How to add a extention to the php.ini file

Question

Hi have Centos 6 installed and busy installing wkhtmltopdf, I only have one step left and that is to include extension=phpwkhtmltox.so to the php.ini file, I added it to /etc/php.ini and reloaded apache and the extention does not take effect.

I check /usr/lib64/php/modules/phpwkhtmltox.so and the file is present.

Is there anything I did wrong?

Is it spelled correctly in php.ini? - should be `extension=...` — meulop, Jan 27 '12 at 14:26
@meulop - yes it's like this in php.ini extension=phpwkhtmltox.so — Elitmiar, Jan 27 '12 at 14:31
It is possible that a different configuration file is being loaded. a) Check the output of `phpinfo();` for the 'Loaded Configuration File' line - see if you are actually using /etc/php.ini (or `php -i | grep php.ini` - although this isn't the same in some environments). You may want to create a new ini file under `/etc/php.d` and add your line to it (e.g. `echo "extension=phpwkhtmltox.so" > /etc/php.d/phpwkhtmltox.ini` ) . Finally, don't just add the line to the bottom of php.ini - the file is divided into sections, add it before the Module Settings. — cyberx86, Jan 27 '12 at 14:46
@cyberx86 - Placing a new ini file under /etc/php.d did the trick, thank you for the advice. — Elitmiar, Jan 27 '12 at 20:34

When adding an extension to PHP:

Ensure you adding it to the correct php.ini file:
- Check the output of phpinfo(); for the 'Loaded Configuration File' line
  - see if you are actually using /etc/php.ini
- Alternatively try: php -i | grep php.ini
  - some environments (e.g. FastCGI) may load a different config file, so this isn't always reliable
php.ini is an INI file - it is divided into sections (with the section names in square brackets). A directive under the wrong section may not be correctly applied. You should add extensions to the '[PHP]' section (typically the first section, it is often followed by sections for 'Module Settings')
PHP loads the ini files from /etc/php.d - it is good practise to add the extension from there. Create a new ini file, named after your module, containing the 'extension=' directive, and any module specific configuration options. For example:
```
echo "extension=phpwkhtmltox.so" > /etc/php.d/phpwkhtmltox.ini
```

Of course, restart Apache/PHP after you have made the changes, and confirm that they were successful using phpinfo();

A note on (2) : the default php.ini file found version 5.6.9 of PHP mentions this : "Section headers (e.g. [Foo]) are also silently ignored, even though they might mean something in the future." — Nigralbus, Jul 22 '15 at 15:36
