PHP array() Function

The array() function is an inbuilt function in PHP which is used to create an array. There are three types of array in PHP:

• Indexed array: The array which contains numeric index. Syntax:

  array( val1, val2, val3, ... )

• Associative array: The array which contains name as keys. Syntax:

  array( key=>val, key=>val, key=>value, ... )

• Multidimensional array: The array which contains one or more arrays. Syntax:

  array( array( val11, val12, ...)
         array( val21, val22, ...)
         ... )

Parameters: This function accepts atmost two parameters as mentioned above and described below:

• val: This parameter is used to hold the value of array.
• key: This parameter is used to hold the key value:

Return Value: This function returns an array of parameters. Below programs illustrates the array() function in PHP: Program 1: This example illustrate the Indexed array. php

<?php
// Create an array
$sub = array("DBMS", "Algorithm", "C++", "JAVA");
// Find length of array
$len = count( $sub );
// Loop to print array elements
for( $i = 0; $i < $len; $i++) {
    echo $sub[$i] . "\n";
}
?>

Program 2: This example illustrate the Associative array. php

<?php
// Declare an associative array
$detail = array( "Name"=>"GeeksforGeeks", 
                 "Address"=>"Noida", 
                 "Type"=>"Educational site");
// Display the output
var_dump ($detail);
?> 

Program 3: This example illustrate the Multidimensional array. php

<?php
// Declare 2D array
$detail = array(array(1, 2, 3, 4),
                array(5, 6, 7, 8));
// Display the output
var_dump ($detail);
?>
