PHP Array Reference : Start the slice from the third array element, and return the rest of the elements in the array
The array_slice() function returns selected parts of an array.
Parameter | Description |
---|---|
array | Required. Specifies an array |
start | Required. Numeric value. Specifies where the function will start the slice.
0 = the first element.
If this value is set to a negative number, the function will start slicing that far from the last element.
-2 means start at the second last element of the array. |
length | Optional. Numeric value. Specifies the length of the returned array.
If this value is set to a negative number, the function will stop slicing that far from the last element. If this value is not set, the function will return all elements, starting from the position set by the start-parameter.
|
preserve | Optional. Specifies if the function should preserve or reset the keys. Possible values:
|
Return Value: | Returns selected parts of an array |
---|---|
PHP Version: | 4+ |
PHP Changelog: | The preserve parameter was added in PHP 5.0.2 |
Start the slice from from the second array element, and return only two elements:
<?php
$a=array("red","green","blue","yellow","brown");
print_r(array_slice($a,1,2));
?>
Using a negative start parameter:
<?php
$a=array("red","green","blue","yellow","brown");
print_r(array_slice($a,-2,1));
?>
With the preserve parameter set to true:
<?php
$a=array("red","green","blue","yellow","brown");
print_r(array_slice($a,1,2,true));
?>
With both string and integer keys:
<?php
$a=array("a"=>"red","b"=>"green","c"=>"blue","d"=>"yellow","e"=>"brown");
print_r(array_slice($a,1,2));
$a=array("0"=>"red","1"=>"green","2"=>"blue","3"=>"yellow","4"=>"brown");
print_r(array_slice($a,1,2));
?>
