A note on the php.net/manual/en/function.strstr.php page: Note: If you only want to determine if a particular needle occurs within haystack, use the faster and less memory intensive function strpos() instead.

@tastro Are there any reputable benchmarks on this?

This might be slower, but IMHO strstr($a, 'are') is much more elegant than the ugly strpos($a, 'are') !== false. PHP really needs a str_contains() function.
