[RESOLVED] Array

[thekidscareya]

I have a variable $email that contains who we want to email. I also have an array called $array.

$array looks like this:

$array = (

"Mr. President" => "[e-mail]"

);

Let's say the user wants to email Mr. President. The $email variable would contain "Mr. President". I want to search $array for the email address for $email and $to equal to the email address for that person.

How do I do this?

well say you have "Mr. President" in a variable called $key you can try

if (isset($array[$key])) {
  $email = "\"$key\" <{$array[$key]}>";
} else {
  echo "key $key doesn't exist.";
}

Well, if you know for sure that the key exists, then you can simply do:
$to = $array[$email];

But here are two better ways that check whether the key is there first:

$array = ('Mr. President' => '[e-mail]');
$email = 'Mr. President';

if (isSet($array[$email]))
    $to = $array[$email];
else
   $to = ''; // Not found

Another way:

$array = ('Mr. President' => '[e-mail]');
$email = 'Mr. President';

$key = array_search($email, $array);
if (FALSE === $key)
    $to = ''; // Not found
else
    $to = $array[$key];

EDIT:

Posted too late. Oh well, you get another example/ways to do the same thing.
