Check if string contains any of the specified words and remove them

I have a variable that I'm trying to check whether it contains a set of specific words. If it contains any of those words, they should be removed.

The code I've tried is:

$title = 'Help my title';    
$array = array("help","test","trying");
    if(0 < count(array_intersect(explode(' ', strtolower($title)), $array))){
      $titlenew = str_replace($array, "", $title);
    }

My expectation is that the above would return:

my title

If it could be case insensitive too, that would be great - although it's not my priority.

Thanks

I'd probably do this with regular expressions:

$str = preg_replace('/\b(word1|word2)\b/i', '', $str);

\b is a word boundary: https://www.php.net/manual/en/regexp.reference.escape.php

You need str_ireplace():

$title = 'Help my title';    
$array = array("help","test","trying");
echo str_ireplace($array, '', $title); // my title
