Posted By Bajarangi soft , Posted On 16-09-2020

array_slice() returns the sequence of elements from the array and we can slice an array using array_slice() to cut an array in any number of arrays.

Syntax for array_slice() and Usage.

array_slice(array, start, length, preserve)

Parameter Description

array       Specifies an input array.

start       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.

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    Specifies if the function should preserve or reset the keys. Possible values:
                    true - Preserve keys
                    false - Default. Reset keys
