If you are not familiar with arrays, check out our Getting Started article.

Let's say you have an array of fruit.

$fruit = array("apple", "banana", "orange");

array_push can be used to add values to the end of an array. In this example, grapes is added to the fruit array.

array_push($fruit, "grapes");

var_dump can be used to print the data structure of the array.

var_dump($fruit);

Which will show that grapes was appended to the array.

array(4) { [0]=> string(5) "apple" [1]=> string(6) "banana" [2]=> string(6) "orange" [3]=> string(6) "grapes" }
