Showing everything..

I've jsut written some code to print out all the variables in the $GLOBALS array..and then I was trying to print out everything in $links_loop. For some reason, this code isn't working correctly;

Code:
<? foreach ($GLOBALS as $item => $var) { echo "&nbsp;&nbsp;$item   =>  $var<BR>"; } 

echo "now array.."; 

foreach ($links_loop as $thing) {  

  foreach ($links_loop['$thing'] as $loop => $val) { echo "&nbsp;&nbsp;$loo   =>   $val"; } 

}  

?>

For some reason, the last foreach is brining up an error. How would I refer to the sub-arrays within $globals?

Thanks

Never mind...I worked it out Smile

Code:
<? foreach ($GLOBALS as $item => $var) { echo "&nbsp;$item   =>  $var<BR>"; } ?> 

<? echo "now array.."; ?> 
<?  

$i = 0; 
foreach ($links_loop as $thing => $val) {  

  $i++; 
  echo "<BR>"; 
  foreach ($links_loop[$thing] as $line => $val) { echo "&nbsp;&nbsp;&nbsp;&nbsp;$line    => $val<BR>"; } 

}  

?>

That prints out everything in the $GLOBALS variable..and all the link variables that are available. May come in handy for people like me, who are working on PHP Plugins Wink

I don't see where you even use $i ?

Why do that when you can just do:

Code:
<pre><?print_r($GLOBALS)?></pre>

Code:
<pre><?print_r(get_defined_vars())?></pre>

for all available variables.

Because in the plugin I was working on, I use;

$i++;
some other stuff here { $add[$i]; }

to populate the add array for use later.

I'm just trying to port over my Count_Impressions plugin to PHP...and it seems to be going quite well :)
