PHP - Return Multidimensional Array Through Foreach

Question

I'm trying to return a value from a multidimensional array, but it doesn't seem to be working.

Array -

[players] => Array
    (
        [0] => Array
            (
                [player] => Necro
                [score] => 0
                [deaths] => 0
                [gq_name] => 
                [gq_kills] => 
                [gq_deaths] => 0
                [gq_score] => 0
                [gq_ping] => 
            )

    )

PHP Foreach

<?php  
$dayzplayers = $results["dayz"]["players"];
          foreach($dayzplayers as $k => $v) {
                  echo ' <b>'.$v["player"].'</b>';
              } ?>

I cannot spot any "dayz" in your array... So $dayzplayers is empty, the loop won't loop. — arkascha

I specify multiple games in the array, thats how I'm specifying the server query specifically. — Necro.

If you do a print_r($v); inside the foreach, what do you get? — m4t1t0

@Jason: no, he posted the debug output above. It is an array, he just didn't post his real data structure. — arkascha

there seems to a special character [SOHplayer] => Necro; analyse it. — जलजनक

The ['player'] index appears to have an invisible control character in the key SOH (Start of Heading)

Try echo ' <b>'.$v[chr(1) . "player"].'</b>'; instead of echo ' <b>'.$v["player"].'</b>';

If the data is what you posted in the first listing, this should work:

foreach($dayzplayers as $player) {
    echo $player[chr(1).'player'];
}

as per http://codepad.org/kUYueGVh

Its so weird. Because when I do a var_dump on $player, it shows the array and clearly shows "player", yet when I do the above code. No output =/ check esclan.org/esclan/dayz# to see.

@Necro Open the dump in an editor where you can see non-graphic characters.

What happens if you echo $player['score'];

It returns the score. But yet when I try 'player' nothing. The array comes back null.

echo (string) $player['player']; or if it indeed does have a SOH character echo var_export($player['player']); See if that helps
