Extract a substring between two characters in a string PHP

Question

Is there a PHP function that can extract a phrase between 2 different characters in a string? Something like substr();

Example:

$String = "[modid=256]";

$First = "=";
$Second = "]";

$id = substr($string, $First, $Second);

Thus $id would be 256

Any help would be appreciated :)

Answer 1

use this code

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

Answer 2

Use:

<?php

$str = "[modid=256]";
$from = "=";
$to = "]";

echo getStringBetween($str,$from,$to);

function getStringBetween($str,$from,$to)
{
    $sub = substr($str, strpos($str,$from)+strlen($from),strlen($str));
    return substr($sub,0,strpos($sub,$to));
}

?>

Answer 3

$String = "[modid=256]";

$First = "=";
$Second = "]";

$Firstpos=strpos($String, $First);
$Secondpos=strpos($String, $Second);

$id = substr($String , $Firstpos, $Secondpos);
