This doesn't solve the strval problem, but in my debug output I wasn't so interested
in the array's name, as in
the meaning/status of the data it contained. Here is an equivalent approach (- the
idea of nesting the two
functions was the subject of a conversation with Torben here, a few days back):
Function ShowList( $title, $aList )
// Debug output routine to echo an array/list to the screen
// requires a documentary name for the list as $title
// requires the array to be listed as $aList
// NB co-requisite FnShowListItem
{
echo "<br>Listing array=$title: n=" . count( $aList );
array_walk( $aList, "FnShowListItem" );
}
Function FnShowListItem( $item, $key ) { echo "<br>$key=" . $item . "~"; }
//end of function ShowList
In the main routine make a call something like:
if ( DEBUG ) ShowList( "Prefixed", $aURLs );
Please feel free to translate it into Polish.
I haven't tried to time/test, but I figured that the array_walk() would be more
efficient than writing an
(interpreted) PHP loop to run through the entire array/list, even with the function
call.
Perhaps someone can confirm/refute that?
