1.2.58. Autoappend¶
Appending a variable to itself leads to enormous usage of memory.
<?php
// Always append a value to a distinct variable
foreach($a as $b) {
$c[] = $b;
}
// This copies the array to itself, and double the size each loop
foreach($a as $b) {
$c[] = $c;
}
?>

Change the variable on the left of the append
Change the variable on the right of the append
