Array in PHP (Create an array, add elements, the length of the array, go through all the elements in the array)

last updated: 5 December 2024

To work with an array in PHP, use the array class.

1. Create an empty array

PHP

$my_arr1 = array();

2. Create a populated array

PHP

$my_arr1 = array("Hello", "Home", "Good");

3. Adding New Elements to the End of an Array

PHP

$my_arr1[] = "Hello";
$my_arr1[] = "Home";
$my_arr1[] = "Good";

4. Array length

The count method is the number of elements in the array.

PHP

$myCount = count($my_arr1);
// $myCount = 3

5. Go through all the elements in the array

PHP

for ($i=0; $i<;count($my_arr1); $i++)
{
     $my_element = $my_arr1[$i];

     // on first iteration
     // $my_element = "Hello"

     // on second iteration
     // $my_element = "Home"

     // on third iteration
     // $my_element = "Good"
}
