Re: [PHP] Finer points of debugging: vardump vs. print_r

[Morgan Curley]

I generally include the following function:
         function dump( $label, $input ){
                 echo( "<PRE>" );
                 echo( "<H2>$label</H2>\n" );
                 print_r( $input );
                 echo( "</PRE>" );
                 return 1;
         }

or if you like javascript this pops up an alert wherever you insert the 
dump call in your page
         function dump( $label, $input ){
                 ob_start();
                 print_r( $input );
                 $gc     = ob_get_contents();
                 ob_end_clean();

                 $gc = preg_replace( "/'/", "\\'", $gc );
                 $gc = preg_replace( '/\n/', '\\n', $gc );
                 echo( "<script>alert( '$label\\n".$gc."' );</script>" );
                 return 1;
         }

then for simple debugging I call
dump( "My Label", $my_var );

With the javascript you can do some cool things like having divs generated 
per $label.
