[TUTORIAL]Verifica daca exista o cheie intr-un array phpBB 3 - ra!z0r - 01-12-2015
In zilele trecute am avut un task, sa gasesc o cheie intr-un array, daca exista atunci sa se afiseze elementul avand cheia specificata.
Exemplu:
Code:
<?php
$my_arr = array( 0 => 'Ion', 1 => 'Vasile', 2 => 'Maria' );
$cheie = 1;
if (array_key_exists($cheie, $my_arr)) {
echo $my_arr[$cheie];
}
else {
echo 'Cheia specificata nu exista in $my_arr';
}
?>
