Installation of extensions on Windows

After installing PHP and a webserver on Windows, you will probably want to install some extensions for added functionality. You can choose which extensions you would like to load when PHP starts by modifying your php.ini. You can also load a module dynamically in your script using dl().

The DLLs for PHP extensions are prefixed with php_.

Nota: In PHP 4.3.1 BCMath, Calendar, COM, Ctype, FTP, MySQL, ODBC, Overload, PCRE, Session, Tokenizer, WDDX, XML and Zlib support is built in. You don't need to load any additional extensions in order to use these functions. See your distributions README.txt or install.txt or this table for a list of built in modules.

The default location PHP searches for extensions is c:\php4\extensions in PHP 4 and c:\php5 in PHP 5. To change this setting to reflect your setup of PHP edit your php.ini file:

Nota: If you are running a server module version of PHP remember to restart your webserver to reflect your changes to php.ini.

The following table describes some of the extensions available and required additional dlls.
