PHP Manual: Returns the size of the array

public int SplFixedArray::count()

This function has no parameters.

Returns the size of the array.

Example #1 SplFixedArray::count example

<?php
$array = new SplFixedArray(5);
echo $array->count() . "\n";
echo count($array) . "\n";
?>

The above example will output:

5
5

Note:
This method is functionally equivalent to SplFixedArray::getSize.

Note:
The count of elements is always equal to the set size because all values are initially initialized with null.
