Global Problem

[Shawazi]

I have the following code in a function. The variable $shipping is not being output outside of the function.

global $insideitem, $tag, $item_arrays, $shiptype, $shipping, $shiparea; 
	if ($tagName == "RateV2Response") 
	{ 
		$shipping = $item_arrays['Rate'][$shiptype];
		echo "$shipping<br>"; //outputs 7.14
		unset($item_arrays);
		$insideitem = false; 
   }

Hmmm....hard to see what is going on from snippet you posted...

<?php
// this line might not even be necessary, usually I'll init
// global at top of script, in rare cases where I use them
$shipping=null;

function some_function() {
    global $shipping;
    // now you can assign values to shipping and effects will be
    // be present throughout script
}
?>

That didn't help. I'm really confused considering this code had been working over a month ago. Now I come back to it and it's just messin with me. It's part of an XML parser I made for shipping with USPS. here is the whole function from part of the script. $shipping is only defined once so I can't be overwriting it.

function endElement($parser, $tagName) 
{ 
	global $insideitem, $tag, $item_arrays, $shiptype, $shipping, $shiparea; 

if ($tagName == "RateV2Response") 
{ 
	$shipping = $item_arrays['Rate'][$shiptype];
	echo "<br>Shipping: $shipping<br>";
	unset($item_arrays);
	$insideitem = false; 
   } 
   if ($tagName == "IntlRateResponse") 
	{ 
		$shipping = $item_arrays['Postage'][$shiptype];
		unset($item_arrays);
		$insideitem = false; 
   } 
}
