How to Get Array Length in PHP - Step by Step Examples

How to Get Array Length in PHP ?

To get the length of an array in PHP, you can use the count function or the sizeof function.

In this example,

We create an integer array named $numbers with some values.
We then use the count function or sizeof function to get the length of the array and store the returned value in $length variable.
Both functions return the length of this array.
Finally, we shall print the value in $length to standard output.

<?php
$numbers = [1, 2, 3, 4, 5];
$length = count($numbers);
echo "Length of array is: $length";
?>

Length of array is: 5

In this example,

We create a string array named $colors with some values.
We then use the count function or sizeof function to get the length of the array and store the returned value in $length variable.
Both functions return the length of this array.
Finally, we shall print the value in $length to standard output.

<?php
$colors = ['red', 'green', 'blue'];
$length = count($colors);
echo "Length of array is: $length";
?>

Length of array is: 3
