  • An array is a variable that can hold more than one value at a time.

Create an Array in PHP

  • In PHP, array() function is used to create the array
  • Arrays in PHP can be divided into three,
    1. Indexed Arrays
    2. Associative arrays
    3. Multidimensional Arrays

PHP Indexed Arrays

  • Indexed Arrays are the arrays with numeric syntax.
  • There are two ways to create an indexed array.
    1. Assigned automatically
    2. Assigned manually

Assigned automatically

     $numbers = array("One", "Two", "Three");

Assigned manually

     $numbers[0] = "One";
	 $numbers[1] = "Two";
	 $numbers[2] = "Three";

PHP Associative Arrays

  • Associative arrays are the arrays with named keys.
  • There are two ways to create associative arrays.
     $numbers = array("number1"=>"1", "number2"=>"2", "number3"=>"3");

     $numbers['number1'] = "1";
	 $numbers['number2'] = "2";
	 $numbers['number3'] = "3";	

PHP Multidimensional Arrays

  • A multidimensional array is an array of arrays or containing one or more arrays.
  • A two-dimensional array is an array of arrays.
  • A three-dimensional array is an array of arrays.
     $vehicles = array

     echo $vehicles[0][0].": Sold: ".$vehicles[0][1].", In stock: ".$vehicles[0][2].".<br>";
     echo $vehicles[1][0].": Sold: ".$vehicles[1][1].", In stock: ".$vehicles[1][2].".<br>";
     echo $vehicles[2][0].": Sold: ".$vehicles[2][1].", In stock: ".$vehicles[2][2].".<br>";
