|
PhpSpreadsheet is a library written in pure PHP and offers a set of classes that
|
|
allow you to read and write various spreadsheet file formats such as Excel and LibreOffice Calc.
|
|
|
|
## PHP Version Support
|
|
|
|
LTS: Support for PHP versions will only be maintained for a period of six months beyond the
|
|
[end of life](https://www.php.net/supported-versions) of that PHP version.
|
|
|
|
Currently the required PHP minimum version is PHP __7.4__, and we [will support that version](https://www.php.net/eol.php) until 28th June 2023.
|
|
|
|
See the `composer.json` for other requirements.
|
|
|
|
## Installation
|
|
|
|
Use [composer](https://getcomposer.org) to install PhpSpreadsheet into your project:
|
|
|
|
```sh
|
|
composer require phpoffice/phpspreadsheet
|
|
```
|
|
|
|
If you are building your installation on a development machine that is on a different PHP version to the server where it will be deployed, or if your PHP CLI version is not the same as your run-time such as `php-fpm` or Apache's `mod_php`, then you might want to add the following to your `composer.json` before installing:
|
|
```json
|
|
{
|
|
"require": {
|
|
"phpoffice/phpspreadsheet": "^1.23"
|
|
},
|
|
"config": {
|
|
"platform": {
|
|
"php": "7.4"
|
|
}
|
|
}
|
|
}
|
|
```
|
|
and then run
|
|
```sh
|
|
composer install
|
|
```
|
|
to ensure that the correct dependencies are retrieved to match your deployment environment.
|
|
|
|
See [CLI vs Application run-time](https://php.watch/articles/composer-platform-check) for more details.
|
|
|
|
### Additional Installation Options
|
|
|
|
If you want to write to PDF, or to include Charts when you write to HTML or PDF, then you will need to install additional libraries:
|
|
|
|
#### PDF
|
|
|
|
For PDF Generation, you can install any of the following, and then configure PhpSpreadsheet to indicate which library you are going to use:
|
|
- mpdf/mpdf
|
|
- dompdf/dompdf
|
|
- tecnickcom/tcpdf
|
|
|
|
and configure PhpSpreadsheet using:
|
|
|
|
```php
|
|
// Dompdf, Mpdf or Tcpdf (as appropriate)
|
|
$className = \PhpOffice\PhpSpreadsheet\Writer\Pdf\Dompdf::class;
|
|
IOFactory::registerWriter('Pdf', $className);
|
|
```
|
|
or the appropriate PDF Writer wrapper for the library that you have chosen to install.
|
|
|
|
#### Chart Export
|
|
|
|
For Chart export, we support following packages, which you will also need to install yourself using `composer require`
|
|
- [jpgraph/jpgraph](https://packagist.org/packages/jpgraph/jpgraph) (this package was abandoned at version 4.0.
|
|
You can manually download the latest version that supports PHP 8 and above from [jpgraph.net](https://jpgraph.net/))
|
|
- [mitoteam/jpgraph](https://packagist.org/packages/mitoteam/jpgraph) (fork with php 8.1 support)
|
|
|
|
and then configure PhpSpreadsheet using:
|
|
```php
|
|
Settings::setChartRenderer(\PhpOffice\PhpSpreadsheet\Chart\Renderer\JpGraph::class); // to use jpgraph/jpgraph
|
|
//or
|
|
Settings::setChartRenderer(\PhpOffice\PhpSpreadsheet\Chart\Renderer\MtJpGraphRenderer::class); // to use mitoteam/jpgraph
|
|
```
|
|
|
|
One or the other of these libraries is necessary if you want to generate HTML or PDF files that include charts.
|

## Patreon
|
|
|
|
I am now running a [Patreon](https://www.patreon.com/MarkBaker) to support the work that I do on PhpSpreadsheet.
|
|
|
|
Supporters will receive access to articles about working with PhpSpreadsheet, and how to use some of its more advanced features.
|
|
|
|
Posts already available to Patreon supporters:
|
|
- The Dating Game
|
|
- A look at how MS Excel (and PhpSpreadsheet) handle date and time values.
|
|
|
|
The next post (currently being written) will be:
|
|
- Looping the Loop
|
|
- Advice on Iterating through the cells in a worksheet.
|
|
|
|
My aim is to post at least one article each month, taking a detailed look at some feature of MS Excel and how to use that feature in PhpSpreadsheet, or on how to perform different activities in PhpSpreadsheet.
|
|
|
|
Planned posts for the future include topics like:
|
|
- Tables
|
|
- Structured References
|
|
- Array Formulae
|
|
- Conditional Formatting
|
|
- Data Validation
|
|
- Formula Debugging
|
|
- Value Binders
|
|
|
|
After a period of six months exclusive to Patreon supporters, articles will be incorporated into the public documentation for the library.

## PHPExcel vs PhpSpreadsheet ?
|
|
|
|
PhpSpreadsheet is the next version of PHPExcel. It breaks compatibility to dramatically improve the code base quality (namespaces, PSR compliance, use of latest PHP language features, etc.).
|
|
|
|
Because all efforts have shifted to PhpSpreadsheet, PHPExcel will no longer be maintained. All contributions for PHPExcel, patches and new features, should target PhpSpreadsheet `master` branch.
|
|
|
|
Do you need to migrate? There is [an automated tool](/docs/topics/migration-from-PHPExcel.md) for that.
