2. Prerequisites
2.1. Software requirements
The following software is required to develop using PHPExcel:
» PHP version 5.2.0 or newer
» PHP extension php_zip enabled *)
» PHP extension php_xml enabled
» PHP extension php_gd2 enabled (if not compiled in)
*) php_zip is only needed by PHPExcel_Reader_Excel2007, PHPExcel_Writer_Excel2007 and
PHPExcel_Reader_OOCalc. In other words, if you need PHPExcel to handle .xlsx or .ods files you will need
the zip extension, but otherwise not.
You can remove this dependency for writing Excel2007 files (though not yet for reading) by using the PCLZip
library that is bundled with PHPExcel. See the FAQ section of this document (2.4.2) for details about this.
PCLZip does have a dependency on PHP’s zlib extension being enabled.
2.2. Installation instructions
Installation is quite easy: copy the contents of the Classes folder to any location within your
application source directories.
Example:
If your web root folder is /var/www/ you may want to create a subfolder called /var/www/Classes/ and copy the files into
that folder so you end up with files:
/var/www/Classes/PHPExcel.php
/var/www/Classes/PHPExcel/Calculation.php
/var/www/Classes/PHPExcel/Cell.php
...
2.3. Getting started
A good way to get started is to run some of the tests included in the download.
Copy the "Examples" folder next to your "Classes" folder from above so you end up with:
/var/www/ Examples/01simple.php
/var/www/ Examples/02types.php
...
Start running the tests by pointing your browser to the test scripts:
http://example.com/ Examples/01simple.php
http://example.com/ Examples/02types.php
...
Note: It may be necessary to modify the include/require statements at the beginning of each of the test scripts if your
"Classes" folder from above is named differently.
2.4. Useful links and tools
There are some links and tools which are very useful when developing using PHPExcel. Please refer
to the PHPExcel CodePlex pages for an update version of the list below.
