PHP - check if a string contains any character in another string

Question

How to check if a string contains any character in another string with PHP?

$a = "asd";
$b = "ds";
if (if_first_string_contains_any_of_the_chars_in_second_string($a, $b)) {
    echo "Yep!";
}

So, in this case, it should echo since the ASD contains both D and S.

I want to do this without regular expressions .

Answer 1

You can do this using

$a = "asd";
$b = "ds";
if (strpbrk($a, $b) !== FALSE)
    echo 'Found it';
else
    echo "nope!";

More details: http://php.net/manual/en/function.strpbrk.php

The second parameter case sensitive.
