note 113617 deleted from function.count by cmb

Note Submitter: MaxTheDragon at home dot nl ---- If you wish to test if an array contains any elements (or is empty), you might tempted to use count to do something like this: <?php if (count($my_array) > 0) { // array is not empty... } // or this ... if (count($my_array) === 0) { // array is empty... } ?> Using the count function here is totally unnecessary and slower. Instead, you should rely on the fact that empty arrays evaluate to false when cast to a boolean: <?php $hasElements = (boolean) $my_array; // or ... $isEmpty = !$my_array; // or in a conditional statement... if ($my_array) { // array is not empty... } ?> Only use count if you need to know if an array contains a specific number of elements n (where n > 0).
