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.

DBMS
Algorithm
C++
JAVA

Program 2: This example illustrate the Associative array.

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

Program 3: This example illustrate the Multidimensional array.

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)
  }
}
