Description:
------------
When variable passed by reference is used in switch() it becomes local for that scope
Test script:
---------------
<?php
function bug( &$var ) {
switch( $var ) {
case 1: $var = 2;
}
}
function workaround( &$var ) {
$val_local = $var;
switch( $val_local ) {
case 1: $var = 2;
}
}
$var = 1; bug( $var ); echo $var , PHP_EOL;
$var = 1; workaround( $var ); echo $var , PHP_EOL;
?>
