Can PHP's glob() be made to find files in a case insensitive manner?

Question

I want all CSV files in a directory, so I use

glob(\'my/dir/*.CSV\')

This however doesn\'t find files with a lowercase CSV extension.

Answer 1

To make it work with all extensions use:

$extension = 'some_extension';
glob('my/dir/*.preg_replace('/(\w)/e', "'['.strtoupper($1).strtolower($1).']'", $extension));
