PHP array_unshift() Function

PHP array_unshift() Function


Hello dear readers! welcome back to another section of our tutorial on PHP. In this tutorial, we will be studying about the PHP Function array_unshift().

The PHP array_unshift() function prepends passed elements to the beginning of the array. Note that the list of elements is prepended as a whole, so that the prepended elements stay in the same order. All the numeric array keys will be modified to start counting from zero while literal keys will not be changed.

Syntax

Following below is the syntax to use this function -

array_unshift($array,$value1,$value2,$value3...)
