PHP | array_slice() Function

By Prem Tiwari in PHP Documentation. Updated on


array_slice() is an inbuilt function of PHP library and it is used to slice an array according tot the user needs.

array_slice() — It returns the sequence of elements from the array array as specified by the offset and length parameters. As already mentioned this function will return the selected or the sliced parts of the given array.

Syntax

array_slice ( array $array , int $offset [, int $length = NULL [, bool $preserve_keys = FALSE ]] ) : array

Parameters
array:
The input array.

offset
If offset is non-negative, the sequence will start at that offset in the array.

If offset is negative, the sequence will start that far from the end of the array.

Note:

The offset parameter denotes the position in the array, not the key.

length
If length is given and is positive, then the sequence will have up to that many elements in it.

If the array is shorter than the length, then only the available array elements will be present.

If length is given and is negative then the sequence will stop that many elements from the end of the array.

If it is omitted, then the sequence will have everything from offset up until the end of the array.

preserve_keys

array_slice() will reorder and reset the integer array indices by default. This behaviour can be changed by setting preserve_keys to TRUE. String keys are always preserved, regardless of this parameter.

Return Values

Returns the slice. If the offset is larger than the size of the array, an empty array is returned.
