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
  
// 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";
}
?>


Output:

DBMS
Algorithm
C++
JAVA

Program 2: This example illustrate the Associative array.




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


Output:

array(3) {
  ["Name"]=>
  string(13) "GeeksforGeeks"
  ["Address"]=>
  string(5) "Noida"
  ["Type"]=>
  string(16) "Educational site"
}

Program 3: This example illustrate the Multidimensional array.




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


Output:

array(2) {
  [0]=>
  array(4) {
    [0]=>
    int(1)
    [1]=>
    int(2)
    [2]=>
    int(3)
    [3]=>
    int(4)
  }
  [1]=>
  array(4) {
    [0]=>
    int(5)
    [1]=>
    int(6)
    [2]=>
    int(7)
    [3]=>
    int(8)
  }
}
