How to delete the first few elements of an array in php

In PHP, we can use the array_splice function to delete elements in an array. The syntax of this function is as follows:

array_splice($array, $start, $length);

Among them, $array is the array to be operated on, $start is the starting position to be deleted, and $length is the number of elements to be deleted. It should be noted that this function will modify the original array.

For example, we have an array $number = [1, 2, 3, 4, 5]. If we want to delete the first three elements, we can write like this:

array_splice($number, 0, 3);

Execute After completing this statement, the $number array will become [4, 5].

Of course, if we just want to get the first few elements instead of removing them, we can use the array_slice function. The syntax of this function is as follows:

array_slice($array, $start, $length);

Among them, $array is the array to be operated on, $start is the starting position to be obtained, and $length is the number of elements to be obtained. It should be noted that this function does not modify the original array.

For example, we have an array $number = [1, 2, 3, 4, 5]. If we want to get the first three elements, we can write like this:

$result = array_slice($number, 0, 3);

Execute After completing this statement, $result will become [1, 2, 3], while $number remains unchanged.

To sum up, if we want to delete the first few elements of an array, we can use the array_splice function, and if we just want to get the first few elements, we can use the array_slice function. You need to choose which function to use based on your specific needs.
