Question

I have a filename with a date in it, the date is always at the end of the filename.
And there is no extension (because of the basename function i use).

What i have:

$file = '../file_2012-01-02.txt';
$file = basename('$file', '.txt');
$date = preg_replace('PATTERN', '', $file);

Im really not good at regex, so could someone help me with getting the date out of the filename.

Thanks

Answer 1

I suggest to use preg_match instead of preg_replace:

$file = '../file_2012-01-02';
preg_match("/.*([0-9]{4}-[0-9]{2}-[0-9]{2}).*/", $file, $matches);
echo $matches[1]; // contains '2012-01-02'
