Check if array is present in another array without exact match

Question

$source = ['domain.com', 'subdomain.value.com'];
$str = ['value.com', 'blur.de', 'hey.as'];

How to check if any of $str is present in $source?

I've tried in_array or array_intersect but both seem to check for exact values, so none match.

In this example, it should match as 'value.com' is present in 'subdomain.value.com'.

you need something more complicated than in_array because there is a bit of extra matching work for the substrings. in_array and array_intersect do only exact matches. Importantly, to find the right solution-- should "subdomain.value" (or just "value", or just "in.va") match to "subdomain.value.com" ? — exa

Answer recommended by PHP Collective

You could replace elements in $source with elements in $str and see how many replacements were made:

str_replace($str, '', $source, $count);
echo $count;
