Hiding specified array keys and values

[Dereksdontrun]

Hi,

I have a script that returns a large array from a query and outputs them to an HTML page.
Most of this data i want visible, but some of it I dont...for example ID fields.

I do however have to return these fields in my queries as they are needed so I cant construct my query to not return them.

What would be really fantastic is if i could hide these specific array keys and values,
In a way that doesnt disrupt my page formatting my showing spaces.

My dream solution would include a way to make these hidden values visible when a key combination was pressed to help with debugging. I appreciate this is going into the realms of Javascript now....

But if anyone could help me with hiding these keys and values using PHP (maybe to append HTML/CSS around the array elements that would be a start

Cheers

"hide" the values?
how about you just don't print the ones you don't want to see?

If you want to be able to see certain things during development, but not in production, you might do something like this:

//  set to "FALSE" when you don't want to see your debugging stuff
const DEBUG_MODE = TRUE;

then, everywhere you have something that helps you debug stuff, do something like this:

print $stuff;
print $otherstuff;

if( DEBUG_MODE ){
    print $debugging_stuff;
}

little confused as to the question but how about echoing inside html comment tags, then you would have to use view source to see them. Basic debugging would say echo them on screen while you are setting it up, then stop, when its in production, if you constantly need them something odd is going on. It may be an idea to include some code in your question.

Thanks for the input all.. have decided on a jQuery solution to hide in the browser...the reason i could not just not print is I need all of my array and I am printing most of it, seems easier to exclude the very few values I dont want to show

once again thanks for your help

That's what everyone was suggesting you do, but it's probably going to be much more easier (and make more sense) to do the exclusion in the PHP code that outputs the values in the first place.

And to do that exclusion in PHP would be as simple as:

$hiddenKeys = array('REQUEST_URI','REQUEST_METHOD');
foreach( $_SERVER as $k => $v ) {
   if( in_array($k,$hiddenKeys) ) continue;
   echo $v;
}

That will print everything in the $_SERVER array except the REQUEST_URI and REQUEST_METHOD (since you haven't actually shown us what you are printing and trying to exclude I made up my own thing)

since it's a query result, it'd probably be even easier than that:

$SQL = "SELECT `print_this`,`this_too`,`and_this`,`not_this` FROM `tablename`";
// once you get your resultset
while( $r = $result->fetch_row() ){
   print $r['print_this'];
   print $r['this_too'];
   print $r['and_this'];
   // and, if you wanted it printed "sometimes,"
   //   just make $print_hidden_fields TRUE
   if( $print_hidden_fields ){
      print $r['not_this'];
   }
}
