How to remove similarity string between two strings in php

Question

I have two strings like this:

$str_1 = 'catalog/view/javascript/bootstrap/css/bootstrap.min.css';
$str_2 = 'catalog/view/javascript/font-awesome/css/font-awesome.min.css';

How can I remove 'catalog/view/javascript/' from $str_2.

Thank you!

you can use explode("/",$str); then you use unset or any remove method — mintra

I did do it. But I want to know some shorter code like XOR operator to get the similarity string or I remove all string is same in two variable. — Diego

Try this

$str_2 = 'catalog/view/javascript/font-awesome/css/font-awesome.min.css';
echo str_replace( "catalog/view/javascript/", "", $str_2 );

I think he wants to determine what should be removed from $str_1.

Possible but that is not what he has written in the question. He has asked how to remove part of the string. If the OP wants a comparison then I am sure something else can be written.

demo here

<?php
$str_1 = 'catalog/view/javascript/bootstrap/css/bootstrap.min.css';
$str_2 = 'catalog/view/javascript/font-awesome/css/font-awesome.min.css';
$length = strlen($str_1);
$index = 0;
while($index < $length)
{
    if(strpos($str_2, substr($str_1, 0, $index + 1)) === false)
        break;
    $index++;
}
$str_2 =  substr($str_2, $index);
echo $str_2;

It seems interesting but I need some shorter code. Thankyou!

@Diego I thought you were remove the same part with str_1 from str_2. It seems you don't want that, $str_1 misleads me?????. $str_2 = 'catalog/view/javascript/font-awesome/css/font-awesome.min.css'; echo $str_2 = substr($str_2, strlen('catalog/view/javascript/')); works for you.

Oh, I'm so sorry if I make you sad. I mean, your code is working, but I want to some shorter code like XOR operator, maybe! Ex: while($str_1[$i] ^ $str_2[$i]) { $i++} ....
