Run the below code with a breakpoint set on the commented line, then issue a command "context-get -d 1" (change stack depth to 1), then "eval $A". The result is null instead of the array.

<?php

function B() {
$B = array();

for ($i = 0; $i < 10; $i++) {
    $B[$i] = 'B>>Item num: ' . ($i+1); /* Place bp here */
}

}

$A = array();

for ($i = 0; $i < 10; $i++) {
$A[$i] = 'Item num: ' . ($i+1);
}

B();
