PHP array_splice() Function

Complete PHP Array Reference

Definition and Usage

The array_splice() function removes selected elements from an array and replaces it with new elements. The function also returns an array with the removed elements.

Syntax

array_splice(array,start,length,array)

Tips and Notes

Tip: If the function does not removes any elements (length=0), the replacment array will be inserted from the position of the start parameter. (See example 3)

Note: The keys in the replacement array are not preserved.

Example 1

<?php
$a1=array(0=>"Dog",1=>"Cat",2=>"Horse",3=>"Bird");
$a2=array(0=>"Tiger",1=>"Lion");
array_splice($a1,0,2,$a2);
print_r($a1);
?>

The output of the code above will be:

Array ( [0] => Tiger [1] => Lion [2] => Horse [3] => Bird ) 

Example 2

The same example as example 1, but the output is the returned array:

<?php
$a1=array(0=>"Dog",1=>"Cat",2=>"Horse",3=>"Bird");
$a2=array(0=>"Tiger",1=>"Lion");
print_r(array_splice($a1,0,2,$a2));
?>

The output of the code above will be:

Array ( [0] => Dog [1] => Cat )

Example 3

With the length parameter set to 0:

<?php
$a1=array(0=>"Dog",1=>"Cat");
$a2=array(0=>"Tiger",1=>"Lion");
array_splice($a1,1,0,$a2);
print_r($a1);
?>

The output of the code above will be:

Array ( [0] => Dog [1] => Tiger [2] => Lion [3] => Cat )
