How to count all elements or values in an array in PHP

Use the PHP count() or sizeof() function

You can simply use the PHP count() or sizeof() function to get the number of elements or values in an array. The count() and sizeof() function returns 0 for a variable that has been initialized with an empty array, but it may also return 0 for a variable that isn't set.

You can additionally use the isset() function to check whether a variable is set or not.

<?php
$days = array("Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat");
 
// Printing array size
echo count($days);
echo "<br>";
echo sizeof($days);
?>
