sql - Extract a substring between two characters in a string PHP -

is there php function can extract phrase between 2 different characters in string? substr();

example:

$string = [modid=256]; $first = "="; $second = "]"; $id = substr($string, $first, $second);

thus $id 256

any help appreciated :)

use code

$input = "[modid=256]"; preg_match('~=(.*?)]~', $input, $output); echo $output[1]; // 256
