Question

How to check if two strings are anagram (same letters different words) in PHP

Answer 1

// Count characters (mode 1: only characters that appear)

function areAnagram($s1, $s2) {
    // Check if arrays are exactly equal (same values & order)
    if (count_chars($s1, 1) === count_chars($s2, 1)) {
        return true;
    } else {
        return false;
    }
}
 
echo (areAnagram('php', 'hpp') ? "yes" : "no") . "\n";
echo (areAnagram('php', 'pph') ? "yes" : "no") . "\n";
echo (areAnagram('php', 'hph') ? "yes" : "no") . "\n";
