Looping Through Multi-Dimensional Arrays Using Foreach

[akogo]

Can you loop through a multi-dimensional array using the “foreach” function, but only make it output key/value pairs that match a specific value?

Yes.

In anticipation of your next question

foreach ($array as $key=>$value) {
   if (is_array($value)) {
      foreach ($value as $key1=>$value1) {
         if ($value1 == searchval) echo "$key1 = $value1<br>";
      }
   }
   else {
      if ($value == searchval) echo "$key = $value<br>";
   }
}

Depending on howmany dimensions yo may have to extend the principle to test if $value1 is_array and so on.

barand,

Thanks! I'll try this and report back the results -- looks like it will work.

Well... you would need a recursive function...

Somethink like :

 function Ecrire($arrDonnees) {
 	foreach($arrDonnees as $strCle => $strValeur) {
 		if(is_array($strValeur)) {
 			Ecrire($strValeur);
 		} else {
 			echo "$strCle => $strValeur<BR/>\n"; 		}
 	}
 }
Ecrire($myarray);

Simply because if you have something like that :
$array[0][1][2][3][4][5] = "something", you have to do lots of foreach...

Thanks barand! With slight modifications for my particular situation, I got your code to make it do exactly what I wanted -- It WORKS! Thanks for the help!
Thanks for the additional code suntra.
