PHP has a built – in function, array_slice() , that you can use to extract a range of elements from an array. To use it, pass it the array to extract the slice from, followed by the position of the first element in the range (counting from zero), followed by the number of elements to extract.
Note: If the array have string keys, the returned array will always preserve the keys
| 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:
