I have encountered a situation where I'm using the foreach() where I need to
assign new data to the $value in the foreach loop, foreach($x as $key ==>
$value). With PHP 5, you can do the ampersand to the $value but I'm using
PHP 4? So, how do you guys do it? I tried this sample code but it only work
in the child array but not the parent arrays... Food for Thought??
Thanks...
--code--
function XmlTreeCDataAsciiLoopThrough(&$tree)
{
foreach($tree as $key => $value)
{
if (is_array($value)) {
XmlTreeCDataAsciiLoopThrough($value);
} else {
if ($key == "VALUE") {
echo $tree[$key]." ###<br>";
$tree[$key] = "#############";
echo $tree[$key]." @@@<br>";
}
}
}
}
