How to count all array elements in PHP ?

We have given an array containing some array elements and the task is to count all elements of an array arr using PHP. In order to do this task, we have the following methods in PHP:

Approach 1: Using count() Method: The count() method is used to count the current elements in an array. It returns 0 for an empty array.

Syntax:

count($array, mode)

Example :

PHP

filter_none

edit
close

play_arrow

link
brightness_4
code

<?php
// PHP program to count all elements
// or values in an array
    
// Use of count() function
$array = array("Geek1", "Geek2",
            "Geek3", "1", "2","3");  
  
echo "Count first array elements: " . count($array) . "\n"
  
$array = array(
  'names' => array("Geek1", "Geek2", "Geek3"), 
  'rank' => array('1', '2', '3')
); 
  
echo "Recursive count: " . count($array, 1) . "\n"
echo "Normal count: " . count($array, 0); 
  
?>

Output



Count first array elements: 6
Recursive count: 8
Normal count: 2 

Approach 2: Using sizeof() Method: The sizeof() method is used to count the number of elements present in an array or any other countable object.

Syntax:

sizeof($array, mode)

Example :

PHP

filter_none

edit
close

play_arrow

link
brightness_4
code

<?php
// PHP program to count all elements
// or values in an array
    
// Use of sizeof() function
$array = array("Geek1", "Geek2"
           "Geek3", "1", "2","3");
  
echo "Count second array elements: "
              . sizeof($array) . "\n"
  
$array = array(
      'names' => array("Geek1", "Geek2", "Geek3"), 
      'rank' => array('1', '2', '3')
); 
  
echo("Recursive count: " . sizeof($array, 1) . "\n"); 
echo("Normal count: " . sizeof($array, 0) . "\n"); 
  
?>

Count second array elements: 6
