Wrap lines to 80
We wrapped lines to make easier the source easier to read, and to have more manageable diffs. This was done with something like: ```sh pandoc --wrap=auto --atx-headers -f markdown -t markdown-fenced_code_attributes+pipe_tables+raw_html+intraword_underscores` ```

## There seems to be a problem with character encoding...
|
||||
|
||||
It is necessary to use UTF-8 encoding for all texts in PhpSpreadsheet. If the script uses different encoding then you can convert those texts with PHP's iconv() or mb_convert_encoding() functions.

PhpSpreadsheet holds an "in memory" representation of a spreadsheet, so it is susceptible to PHP's memory limitations. The memory made available to PHP can be increased by editing the value of the memory_limit directive in your php.ini file, or by using ini_set('memory_limit', '128M') within your code (ISP permitting).

# AutoFilter Reference
|
||||
|
||||
|
||||
## Introduction
|
||||
|
||||
Each worksheet in an Excel Workbook can contain a single autoFilter range. Filtered data displays only the rows that meet criteria that you specify and hides rows that you do not want displayed. You can filter by more than one column: filters are additive, which means that each additional filter is based on the current filter and further reduces the subset of data.

|
||||
|
||||
When an AutoFilter is applied to a range of cells, the first row in an autofilter range will be the heading row, which displays the autoFilter dropdown icons. It is not part of the actual autoFiltered data. All subsequent rows are the autoFiltered data. So an AutoFilter range should always contain the heading row and one or more data rows (one data row is pretty meaningless), but PhpSpreadsheet won't actually stop you specifying a meaningless range: it's up to you as a developer to avoid such errors.

To determine if a filter is applied, note the icon in the column heading. A drop-down arrow (![01-03-filter-icon-1.png](./images/01-03-filter-icon-1.png "")) means that filtering is enabled but not applied. In MS Excel, when you hover over the heading of a column with filtering enabled but not applied, a screen tip displays the cell text for the first row in that column, and the message "(Showing All)".

In MS Excel, Simple Filters are a dropdown list of all values used in that column, and the user can select which ones they want to display and which ones they want to hide by ticking and unticking the checkboxes alongside each option. When the filter is applied, rows containing the checked entries will be displayed, rows that don't contain those values will be hidden.

### SYLK
|
||||
|
||||
This is the Microsoft Multiplan Symbolic Link Interchange (SYLK) file format. Multiplan was a predecessor to Microsoft Excel™. Files normally have an extension of .slk. While not common, there are still a few applications that generate SYLK files as a cross-platform option, because (despite being limited to a single worksheet) it is a simple format to implement, and supports some basic data and cell formatting options (unlike CSV files).

### Gnumeric
|
||||
|
||||
The Gnumeric file format is used by the Gnome Gnumeric spreadsheet application, and typically files have an extension of .gnumeric. The file contents are stored using eXtensible Markup Language (XML) markup, and the file is then compressed using the GNU project's gzip compression library.

|
||||
### CSV
|
||||
|
||||
Comma Separated Value (CSV) file format is a common structuring strategy for text format files. In CSV flies, each line in the file represents a row of data and (within each line of the file) the different data fields (or columns) are separated from one another using a comma (","). If a data field contains a comma, then it should be enclosed (typically in quotation marks ("). Sometimes tabs "\t", or the pipe symbol ("|"), or a semi-colon (";") are used as separators instead of a comma, although other symbols can be used. Because CSV is a text-only format, it doesn't support any data formatting options.

Nevertheless, the variations are fairly small, and many implementations allow users to glance at the file (which is feasible because it is plain text), and then specify the delimiter character(s), quoting rules, etc.

**Warning:** Microsoft Excel™ will open .csv files, but depending on the system's regional settings, it may expect a semicolon as a separator instead of a comma, since in some languages the comma is used as the decimal separator. Also, many regional versions of Excel will not be able to deal with Unicode characters in a CSV file.

### HTML
|

HyperText Markup Language (HTML) is the main markup language for creating web pages and other information that can be displayed in a web browser. Files typically have an extension of .html or .htm. HTML markup provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes and other items. Since 1996, the HTML specifications have been maintained, with input from commercial software vendors, by the World Wide Web Consortium (W3C). However, in 2000, HTML also became an international standard (ISO/IEC 15445:2000). HTML 4.01 was published in late 1999, with further errata published through 2001. In 2004 development began on HTML5 in the Web Hypertext Application Technology Working Group (WHATWG), which became a joint deliverable with the W3C in 2008.

|
||||
```
|
||||
> See Examples/Reader/exampleReader01.php for a working example of this code.
|
||||
|
||||
The load() method will attempt to identify the file type, and instantiate a loader for that file type; using it to load the file and store the data and any formatting in a `Spreadsheet` object.
|
||||
> See Examples/Reader/exampleReader01.php for a working example of this
|

|
||||
|
||||
The method makes an initial guess at the loader to instantiate based on the file extension; but will test the file before actually executing the load: so if (for example) the file is actually a CSV file or contains HTML markup, but that has been given a .xls extension (quite a common practise), it will reject the Xls loader that it would normally use for a .xls file; and test the file using the other loaders until it finds the appropriate loader, and then use that to read the file.

||||
|

While easy to implement in your code, and you don't need to worry about the file type; this isn't the most efficient method to load a file; and it lacks the flexibility to configure the loader in any way before actually reading the file into a `Spreadsheet` object.

## Creating a Reader and Loading a Spreadsheet File
|

If you know the file type of the spreadsheet file that you need to load, you can instantiate a new reader object for that file type, then use the reader's load() method to read the file to a `Spreadsheet` object. It is possible to instantiate the reader objects for each of the different supported filetype by name. However, you may get unpredictable results if the file isn't of the right type (e.g. it is a CSV with an extension of .xls), although this type of exception should normally be trapped.

### Combining Multiple Files into a Single Spreadsheet Object
|
||||
|
||||
While you can limit the number of worksheets that are read from a workbook file using the setLoadSheetsOnly() method, certain readers also allow you to combine several individual "sheets" from different files into a single `Spreadsheet` object, where each individual file is a single worksheet within that workbook. For each file that you read, you need to indicate which worksheet index it should be loaded into using the setSheetIndex() method of the $reader, then use the loadIntoExisting() method rather than the load() method to actually read the file into that worksheet.

### A Brief Word about the Advanced Value Binder
|
||||
|
||||
When loading data from a file that contains no formatting information, such as a CSV file, then data is read either as strings or numbers (float or integer). This means that PhpSpreadsheet does not automatically recognise dates/times (such as "16-Apr-2009" or "13:30"), booleans ("TRUE" or "FALSE"), percentages ("75%"), hyperlinks ("http://www.phpexcel.net"), etc as anything other than simple strings. However, you can apply additional processing that is executed against these values during the load process within a Value Binder.

|
||||
|

A Value Binder is a class that implement the \PhpOffice\PhpSpreadsheet\Cell\IValueBinder interface. It must contain a bindValue() method that accepts a \PhpOffice\PhpSpreadsheet\Cell and a value as arguments, and return a boolean true or false that indicates whether the workbook cell has been populated with the value or not. The Advanced Value Binder implements such a class: amongst other tests, it identifies a string comprising "TRUE" or "FALSE" (based on locale settings) and sets it to a boolean; or a number in scientific format (e.g. "1.234e-5") and converts it to a float; or dates and times, converting them to their Excel timestamp value – before storing the value in the cell object. It also sets formatting for strings that are identified as dates, times or percentages. It could easily be extended to provide additional handling (including text or cell formatting) when it encountered a hyperlink, or HTML markup within a CSV file.

### Combining Multiple Files into a Single Spreadsheet Object
|
||||
|
||||
While you can limit the number of worksheets that are read from a workbook file using the setLoadSheetsOnly() method, certain readers also allow you to combine several individual "sheets" from different files into a single `Spreadsheet` object, where each individual file is a single worksheet within that workbook. For each file that you read, you need to indicate which worksheet index it should be loaded into using the setSheetIndex() method of the $reader, then use the loadIntoExisting() method rather than the load() method to actually read the file into that worksheet.

### Combining Read Filters with the setSheetIndex() method to split a large CSV file across multiple Worksheets

An Xls BIFF .xls file is limited to 65536 rows in a worksheet, while the Xlsx Microsoft Office Open XML SpreadsheetML .xlsx file is limited to 1,048,576 rows in a worksheet; but a CSV file is not limited other than by available disk space. This means that we wouldn’t ordinarily be able to read all the rows from a very large CSV file that exceeded those limits, and save it as an Xls or Xlsx file.

### A Brief Word about the Advanced Value Binder
|
||||
|
||||
When loading data from a file that contains no formatting information, such as a CSV file, then data is read either as strings or numbers (float or integer). This means that PhpSpreadsheet does not automatically recognise dates/times (such as "16-Apr-2009" or "13:30"), booleans ("TRUE" or "FALSE"), percentages ("75%"), hyperlinks ("http://www.phpexcel.net"), etc as anything other than simple strings. However, you can apply additional processing that is executed against these values during the load process within a Value Binder.

|
||||
|

A Value Binder is a class that implement the \PhpOffice\PhpSpreadsheet\Cell\IValueBinder interface. It must contain a bindValue() method that accepts a \PhpOffice\PhpSpreadsheet\Cell and a value as arguments, and return a boolean true or false that indicates whether the workbook cell has been populated with the value or not. The Advanced Value Binder implements such a class: amongst other tests, it identifies a string comprising "TRUE" or "FALSE" (based on locale settings) and sets it to a boolean; or a number in scientific format (e.g. "1.234e-5") and converts it to a float; or dates and times, converting them to their Excel timestamp value – before storing the value in the cell object. It also sets formatting for strings that are identified as dates, times or percentages. It could easily be extended to provide additional handling (including text or cell formatting) when it encountered a hyperlink, or HTML markup within a CSV file.

## Cell Caching
|
||||
|
||||
PhpSpreadsheet uses an average of about 1k/cell in your worksheets, so large workbooks can quickly use up available memory. Cell caching provides a mechanism that allows PhpSpreadsheet to maintain the cell objects in a smaller size of memory, on disk, or in APC, memcache or Wincache, rather than in PHP memory. This allows you to reduce the memory usage for large workbooks, although at a cost of speed to access cell data.

|

|

When using CACHE_TO_DISCISAM all cells are held in a temporary disk file, with only an index to their location in that file maintained in PHP memory. This is slower than any of the CACHE_IN_MEMORY methods, but significantly reduces the memory footprint. By default, PhpSpreadsheet will use PHP's temp directory for the cache file, but you can specify a different directory when initialising CACHE_TO_DISCISAM.

Like CACHE_TO_DISCISAM, when using CACHE_TO_PHPTEMP all cells are held in the php://temp I/O stream, with only an index to their location maintained in PHP memory. In PHP, the php://memory wrapper stores data in the memory: php://temp behaves similarly, but uses a temporary file for storing the data when a certain memory limit is reached. The default is 1 MB, but you can change this when initialising CACHE_TO_PHPTEMP.
