Answers for "how to match array element with different array count in php"

php count array elements with specific key

$cnt = count(array_filter($array,function($element) {
  return $element['your_key']=='foo';
}));

php check if all array values are the same

// All values are equal
if (count(array_unique($allvalues)) === 1 && end($allvalues) === 'true') {

}

// Check the thing you don't want
if (in_array('false', $allvalues, true)) {

}
