array loops

[nikko50]

Hi Guys. Tracy here. I have an array call email[]. How can I loop through this array and concat all the values in one variable. Thanks
Tracy🙂

$count = count($email));
$new_var = "";
$i = 0;
for ($i = 0; $i < $count; $i ++) {
  $new_var = new_var . $email[$i];
}

depending upon what you are trying to accomplish, you might also look into serialize

Thanks Lite!!

Or just [man]implode[/man]...

$var = implode(', ', $email);

[Sxooter]

$newvar = implode("",$arr_var);

Another option is to use [man]implode()[/man].

$email = array("[e-mail]", "[e-mail]", "[e-mail]", "[e-mail]");
$emailconcat = implode(", ", $email);
echo $emailconcat;

The above code would output:
[e-mail], [e-mail], [e-mail], [e-mail]

[edit]sxooter and LordShryku, you two are in my head tonight 😉 I'd have been here sooner, but I was writing out the whole thing.[/edit]
