PHP check() work

“check() work” is utilized to get them all to outnumber of components of an exhibit.

Syntax:

    count(array, [count_mode])

Here,

• cluster is the name of an info exhibit
• count_mode is a discretionary parameter and its default value is 0, it has two values
• 0 – It doesn’t check all components of a multidimensional exhibit
• 1 – It checks all components of a multidimensional exhibit

Example:

    Input:
    $arr1 = array("101", "102", "103", "104", "105");

    Output:
    arr1 has 5 elements

PHP code: Using single-dimensional cluster

<?php    
    $arr1 = array("101", "102", "103", "104", "105");
    $arr2 = array("Amit", "Abhishek", "Prerana", "Aleesha", "Prem");
	
	$len = count($arr1);
	print ("arr1 has $len elements\n");
	$len = count($arr2);
	print ("arr2 has $len elements\n");	
?>

Output

arr1 has 5 elements
arr2 has 5 elements

PHP code: Using multidimensional cluster

<?php    
    $students = array(
        "101" => array(
                "name" => "Amit",
                "age" => 21,
            ),
        "102" => array(
                "name" => "Abhi",
                "age" => 20,
            )
        );

    $len = count($students);
    print ("count value = $len (count_mode is not provided)\n");

    $len = count($students, 0);
    print ("count value = $len (count_mode is set to 0)\n");    
    
    $len = count($students, 1);
    print ("count value = $len (count_mode is set to 1)\n");    
?>

Output

count value = 2 (count_mode is not provided)
count value = 2 (count_mode is set to 0)
count value = 6 (count_mode is set to 1)
