This will truncate a longer string to a smaller string of specified length (e.g. the “25” value in the code below) while replacing the middle portion with a separator exactly in the middle. Useful when you need to truncate a string but still show the beginning (e.g. for sorting and because it is most recognizable) and also show the end (perhaps to show a file name).
<?php $longString = 'abcdefghijklmnopqrstuvwxyz0123456789z.jpg'; $separator = '/.../'; $separatorlength = strlen($separator) ; $maxlength = 25 - $separatorlength; $start = $maxlength / 2 ; $trunc = strlen($longString) - $maxlength; echo substr_replace($longString, $separator, $start, $trunc); //prints "abcdefghij/.../56789z.jpg" ?>
