Replace value in associative array using foreach()

[shreyaskudav]

This is how I defined the array:

$j = 1;while($j < $i){$battlepokemon[$j] = array('battle_poke' => $battle_poke[$j], 'battle_level' => $battle_level[$j], 'battle_health' => $battle_health[$j]);$j++;}

So the structure is something like this:

battlepokemon[1]{battle_poke => xxxxbattle_level => 10battle_health => 50}battlepokemon[2]{battle_poke => xxxxbattle_level => 10battle_health => 50}... and so on... 

Lets say.. I want to replace the value battlepokemon[1] => battle_health(key) from 50 to 100 using foreach()..

How should I do that??

 

I don't want to do it manually like: $val[$key] = 100; or something like that...!

foreach($battlepokemon as $key => $value){  $battlepokemon[$key]['battle_health'] *= 2;}

I tried but didnt work!!

Well it should work, are you sure your while loop code works? Try adding print_r($battlepokemon); after your while loop to verify the array data.

IF you want to target specific array item battlepokemon[1] you would have to filter it with if condition to an id ref or similar that would uniquely identify it, else all records would change.

$i = 1;foreach ($battlepokemon as $key => $value){if($value['opponent_increment'] == $opponent_increment){$value['battle_health'] = 0;echo "Data replaced!";}$i++;}

As you said dsonesuk!

This code is working properly..only the assignment of '0' to the attr $value['battle_health'] is not working! is the statement correct??

?? I don't $opponent_increment relates to, but I'm guessing the $j increment or now the index value used for in original post battlepokemon[1] or battlepokemon[2]

        foreach ($battlepokemon as $key => $value) {            if ($battlepokemon[$key]['opponent_increment'] == $opponent_increment) {                $battlepokemon[$key]['battle_health'] = 0;                echo "Data replaced!";            }        }

but you could get same result with

        foreach ($battlepokemon as $key => $value) {            if ($key== $opponent_increment) {                $battlepokemon[$key]['battle_health'] = 0;                echo "Data replaced!";            }        }
