ARRAY_UNSHIFT(3) 1 ARRAY_UNSHIFT(3)
array_unshift - Prepend one or more elements to the beginning of an array
SYNOPSIS
int array_unshift (array &$array, mixed $value1, [mixed $...])
DESCRIPTION
array_unshift(3) prepends passed elements to the front 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 numerical array keys will be modified to start counting from zero while literal keys won't
be touched.
PARAMETERS
o $array
- The input array.
o $value1
- First value to prepend.
RETURN VALUES
Returns the new number of elements in the $array.
EXAMPLES
Example #1
array_unshift(3) example
<?php
$queue = array("orange", "banana");
array_unshift($queue, "apple", "raspberry");
print_r($queue);
?>
The above example will output:
Array
(
[0] => apple
[1] => raspberry
[2] => orange
[3] => banana
)
