How to delete the first value of an array in php

In PHP, deleting the first value of an array can be achieved through the following methods.

Method 1: Use array_shift() function

array_shift() function can delete the first element in the array and return the value of this element.

$myArray = array("apple", "banana", "orange"); $firstValue = array_shift($myArray); print_r($myArray); // 输出：Array ( [0] => banana [1] => orange ) echo $firstValue; // 输出：apple

Method 2: Use the unset() function and array_values() function

The unset() function can delete the element at the specified position in the array, and the array_values() function can rearrange the keys of the array name.

$myArray = array("apple", "banana", "orange"); unset($myArray[0]); $myArray = array_values($myArray); print_r($myArray); // 输出：Array ( [0] => banana [1] => orange )

Method 3: Use the array_slice() function

array_slice() function can return a segment of elements in the array, so we can delete the first element of the array and then return the remaining elements .

$myArray = array("apple", "banana", "orange"); $myArray = array_slice($myArray, 1); print_r($myArray); // 输出：Array ( [0] => banana [1] => orange )
