Hello ,i tried to use this code to replace any __Random_and[x,y] with rand(x,y) but it didn't run please help me

PHP

function charCallbackRand($matches1){
    $charOne = (int)$matches1[1];
    $charTwo = (int)$matches1[2];
    return rand($charOne,$charTwo);
    }
    $myword = __Random_and[22,95];
    $result = preg_replace_callback('/__Random_anm\[(\d+),(\d+)\]/', 'charCallbackRand', $myword);

What I have tried:

PHP

function charCallbackRand($matches1){
    $charOne = (int)$matches1[1];
    $charTwo = (int)$matches1[2];
    return rand($charOne,$charTwo);
    }
    $myword = __Random_and[22,95];
    $result = preg_replace_callback('/__Random_anm\[(\d+),(\d+)\]/', 'charCallbackRand', $myword);

Instead of using a preg_replace_callback() you can directly insert the wanted numbers from the original text with preg_replace()

Try this:

PHP

$string = '__Random_and[22,95]';
$pattern = '/__Random_and\[(\d+),(\d+)\]';
$replacement = 'rand($1,$2)';
$result preg_replace($pattern, $replacement, $string);

RegEx only apply on strings, not on code.

PHP

function charCallbackRand($matches1){
    $charOne = (int)$matches1[1];
    $charTwo = (int)$matches1[2];
    return 'rand('.$charOne.','.$charTwo.')';
    }
    $myword = '__Random_and[22,95]';
    $result = preg_replace_callback('/__Random_anm\[(\d+),(\d+)\]/', 'charCallbackRand', $myword);

Your code is way complicated for doing such a simple thing, see Solution 1.
