How to get a substring between two strings in PHP?

Answer 1

UTF-8 version of @Alejandro Iglesias answer, will work for non-latin characters:

function get_string_between($string, $start, $end){
    $string = ' ' . $string;
    $ini = mb_strpos($string, $start, 0, 'UTF-8');
    if ($ini == 0) return '';
    $ini += mb_strlen($start, 'UTF-8');
    $len = mb_strpos($string, $end, $ini, 'UTF-8') - $ini;
    return mb_substr($string, $ini, $len, 'UTF-8');
}

$fullstring = 'this is my [tag]dog[/tag]';
$parsed = get_string_between($fullstring, '[tag]', '[/tag]');

echo $parsed; // (result = dog)
