how to get length of integers in PHP ?

php integer

$num_length = strlen((string)$num);if($num_length == 10) {    // Pass} else {    // Fail}

php integer

if (preg_match('/^\d{10}$/', $string)) {  // pass} else {  // fail}

php integer

This will work for almost all cases (except zero) and easily coded in other languages:

$length = ceil(log10(abs($number) + 1)
