Use the PHP
You can simply use the PHP
sizeof() function to get the number of elements or values in an array. The
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); ?>
