arrays against array

[Anguz]

if I want to compare all the values in two arrays, can I do it like this?

Code Select Expand

$var = ($array1 == $array2 ? $array3 : '');

or do I have to do it like this?

Code Select Expand

for ($i = '0'; $i < count($array1); $i++)
{
   $var = ($array1[$i] == $array2[$i] ? $array3[$i] : '');
}

note that only one of the comparisons will return true

thanks for your help

hmm maybe I should escape the loop once there's a match, or in the next loop, $var will be empty again...

then maybe something like this?

Code Select Expand

for ($i = '0'; $i < count($array1); $i++)
{
   if ($array1[$i] == $array2[$i])
   {
      $var = $array3[$i];
      break;
   }
   else
   {
      $var = '';
   }
}

Code Select Expand

$worked = true;
foreach($array1 as $a)
   if (!in_array($a, $array2))
   {
      $worked = false;
      break;
   }

hmm... I see... not exactly what I was asking, but you gave me an idea

I just looked up in_array() and also found array_search()

I can do with those something I've been wondering how to

thank you!
