Learn how to delete an element from an array in php?

By admin|PHP

There is an easy way to delete an element from a php array. It is unset.

<?php $x = array(1, 2); unset($x[0]); var_dump($x); ?> result is, 

array(1) {   [1]=>   int(2) } 

unset

(PHP 4, PHP 5)

unset — Unset a given variable

void unset ( mixed $var [, mixed $... ] )

unset() destroys the specified variables.

The behavior of unset() inside of a function can vary depending on what type of variable you are attempting to destroy.

If a globalized variable is unset() inside of a function, only the local variable is destroyed. The variable in the calling environment will retain the same value as before unset() was called.
