count — Count all elements in an array, or something in an object.
|
According to the website, sizeof is an alias of count, so they should be running the same code. Perhaps sizeof has a little bit more lag because it needs to resolve it to count? It should be very minimal though. |
Example
<?php
$myArray = array("hen","tiger","bear");
$count = count($myArray);
echo $count;
?>
Output
3
