You didn't read my code closely enough: I said:

If I replace the problem line

         foreach ( array_keys($data) as $key2 )
                   ^^^^^^^^^^

with the alternate

         foreach ( $data as $key2=>$val2 )

I just thought I would see if anyone else can reproduce it! Ok. The problem is in the following snippet of code. ( Note : this exmaple is extremely contrived, and is the essence of a much more complicated situation involving a function call from a class method... ) <?php

     $data = array( "A" => "AA" , "B" => "BB", "C"=> "CC", "D"=> "DD", "E"

=> "EE" );

     print "<pre>\n";
     foreach ( $data as $key1=>$val1 )
     {
//        foreach ( $data as $key2=>$val2 )
         foreach ( array_keys($data) as $key2 )   // <= PROBLEM IS HERE
         {
             if ( $key1 == $key2 )
                 print "<b>$key2</b>";
             else
                 print $key2;

             print "  ";
         }
         print "\n";
     }

     print "</pre>";

?> I beleive it should generate <pre> <b>A</b> B C D E A <b>B</b> C D E A B <b>C</b> D E A B C <b>D</b> E A B C D <b>E</b> </pre> Instead it generates <pre> <b>A</b> B C D E </pre> If I replace the problem line

         foreach ( array_keys($data) as $key2 )

with the alternate

         foreach ( $data as $key2=>$val2 )

then it works fine. I am using PHP 4.0.4pl1.

I haven't taken a very good look at your code, but as I understand you believe that: foreach ($data as $key) delivers the same $key as in: foreach ($data as $key=>$value) Well... it doesn't. Check the manual on it. If you use the foreach ($x as $y) construction, $y is the value... not the key. Take a look at: http://www.php.net/manual/en/control-structures.foreach.php <Quote from PHP manual> foreach(array_expression as $value) foreach(array_expression as $key => $value) </Quote from PHP manual> I think this solves your problem... </Reply> -- * R&zE: -- »»»»»»»»»»»»»»»»»»»»»»»» -- Renze Munnik -- DataLink BV -- -- E: renze@datalink.nl -- W: +31 23 5326162 -- F: +31 23 5322144 -- M: +31 6 21811143 -- -- Stationsplein 82 -- 2011 LM HAARLEM -- Netherlands -- -- http://www.datalink.nl -- «««««««««««««««««««««««« -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: php-general-unsubscribe@lists.php.net For additional commands, e-mail: php-general-help@lists.php.net To contact the list administrators, e-mail: php-list-admin@lists.php.net
