PHP Get Array Length

 To count the array length we use count method, it can be use to count the no. of properties of an object.

The structure of count is:

int count ($var [,int $mode=COUNT_NORMAL]);

Where 

$var is an array

mode is optional and we can set this parameter to COUNT_RECURSIVE (or 1), count() will recursively count the array. This option is beneficial for multidimensional array.Default value for this mode is 0.

 

Code:

<?php

$colorList = array("apple"=>"red",

"grass"=>"green",

"sky"=>"blue",

"night"=>"black",

"wall"=>"white");

echo "Array size with count: ".count($colorList);

?>

Output:

Array size with count: 5
