There are a few common reasons why custom php.ini files won’t work.
- Check the file name
Often if you’re saving it in Windows – for example with Notepad – the file may have been accidentally named “php.ini.txt”. Please ensure this isn’t the case. - Is the file in the script directory?
Make sure the php.ini wasn’t placed in a subfolder, as it will only take affect for that folder and subfolders.
