how to loop array keys?

[scialom]

Hi all,

I am sending to a function an array
I need to be able to loop the keys (which I don't know them) and get their values.

how can I do so?

thanks!

You could use a foreach loop or [man]array_keys/man.

laserlight is right.

"looping" arrays and getting both the "key" and "value" is a basic feature of PHP.

function MyFunction($array)
{
  foreach ($array as $key => $value) echo "$key=$value<br>";
}

MyFunction(array(
  "apple" => "fruit",
  "holden" => "car",
  "rock" => "hard"
))
