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 )
No matter which method you use, you can easily delete the first value in a PHP array.
