Trim a string with an array list

Question

I want to be able to trim a string where values match an array like this

$image_formats = array('.png','.jpg', '.jpeg', '.gif');
$file = 'image1.png';

$file_stripped = trim($file, $image_formats);

Wanted Result: 'image1'

Is there a function for this, whats the best method to go about achieving this?

php.net/manual/en/function.pathinfo.php in addition u can also use in_array() function — Michał Szałapski

You can use str_replace passing an array of search values:

$image_formats = array('.png','.jpg', '.jpeg', '.gif');
$file = 'image1.png';

$file_stripped = str_replace($image_formats, '', $file);

trim() is for removing matches of individual characters, not longer strings.

You can convert $image_formats to a regular expression and use preg_replace().

$image_formats = '/\.(png|jpg|jpeg|gif)$/';
$file_stripped = preg_replace($image_formats, '', $file);
