$arr1 = [1, 2, 3, 4, 5];
$arr2 = $arr1;
$arr2[0] = '!';
echo $arr1[0];
echo $arr2[0];
?>
Aşakdaky kodyň nähili netije berjekdigini aýdyň:
<?php
$arr1 = [1, 2, 3, 4, 5];
$arr2 = &$arr1;
$arr1[0]++;
echo $arr1[0];
echo $arr2[0];
?>
Aşakdaky kodyň nähili netije berjekdigini aýdyň:
<?php
$arr1 = [1, 2, 3, 4, 5];
