You need to restart MAMP (Or indeed any Apache Server) for changes in php.ini to take effect. Restart MAMP using the GUI.

If you are still experiencing no changes, it s possible you are editing the wrong php.ini file. In MAMP, each php version has it s own php.ini file.

To make utterly sure you are editing the right php.ini file, use the following steps:

1. Create a new .php file in your favourite text editor.

2. Type

   <?php phpinfo(); ?> 
   

   and save it in MAMP s htdocs directory.

3. Save it as index.php

4. Make sure MAMP is running!
5. Start Safari, or any browser, and type "localhost:8888" into your URL bar.
6. You should see a purple table filled with information about your apache server.
7. The 6th row should be titled "Configuration File (php.ini)", and on the right of this, a path should be displayed to the php.ini file apache is currently using. It should look like this: "/Applications/MAMP/bin/php/php5.4.4/conf"
8. Now, either use Finder to look browse to this location and edit the .ini file with Text Edit, or use Terminal.
9. If you want to use Terminal, open a new window and type the following: cd (and then copy and paste the path you gained from step 6) . It should look like something like this: cd /Applications/MAMP/bin/php/php5.4.4/conf
10. Now type ls
11. Typing ls will show you the files within the conf directory. The correct php.ini file should be displayed amongst other files such as pear.conf . If you can see php.ini , we re nearly there. If not, you ve gone wrong somewhere, so read over the previous steps.
12. Now type sudo nano /Applications/MAMP/bin/php/php5.4.4/conf/php.ini
13. And give Terminal your password when it asks for it
14. The php.ini file will be opened in Terminal s integrated text-editor, nano. Edit it, and save it using Nano.
15. Simply quit terminal. 15) Restart Apache using MAMP s GUI 16) Browse to localhost:8888 in your favourite browser. Your changes should be reflected in the configuration screen.

I understand this instructions may be hard to follow, but just contact me if you want to use team viewer or something to get this working! Good luck

Possible answers:

• You forgot to restart the Apache webserver after the change
• PHP uses a php.ini from a different location (Check the PHPIniDir setting in your Apache config).

It seems that there are 2 php.ini files in the MAMP installation. The one that seems to be parsed in my case is not in the config/ folder but in the bin/php/php5.3.14/conf/php.ini
