global

hi
i posted a few threads so far but didn't get answers... maybe i'm doing something wrong?!

i'll try one more time.
i have a situation where i have to declare global variables like:

global $moo; $foo; $etc....

the problem i noticed is if i have long number of globals sometimes they don't get processed - like they are not there. but if i move the variable i need to another line with "global" in front, it works...

can somebody please explain why is this happening? i thougth there isn't any limit of how many variables should i have after "global"....

thanks..

Use comma instead of semicolons, e.g.

global $var1, $var2, $var3;

thanks...

now this is wierd. both codes below are the same to me the first one works.. the second doesn't...

code 1 - this works - if you change $name...
##############################
<?

$name = "foo";

function checkTag($one, $two)
{
echo $one." is dufferent then ".$two;
}

switch ($name) {

		case "don":  
						echo "mooo";		   
					   	break;


		default:		
						checkTag("uno", "dos");
						break;

}
?>

######################################

code two - this doesn't work - the error i get is:
Cannot redeclare checktag() (previously declared......

here is the code:

<?
function startElement($parser, $name, $attrs) {

global $usless_tag, $open_tag, $tag;

if (!( (in_array($name, $usless_tag)) == 1) ) {

function checkTag($o_tag, $the_name) { // << this is the error line...

											if ($format= $o_tag[$the_name]) {
          					 					 echo $format;
        										} 

							} 	

switch ($name) {

		case "HOTELID": 
						break;

		default:		
						checkTag($open_tag, $name);
						break;
			 }

}

$tag = $name;

}
?>

how are these 2 codes different?!

thanks...

Why are you defining function inside another function? Take it out..

Also
if ($format= $o_tag[$the_name]) {
should use == instead of =.

sorry... that was stupid - i mean function into function --- this is the 12 th hour so i must be seeing things.... the "$format=" is ok though - i don't compare it - i create the variable there...

thanks...
