Associate PHP index with another array - php

Question

I have 3 explode statements:
$emails = explode(',', $row['email']);
$firstnames = explode(',', $row['first_name']);
$lastnames = explode(',', $row['last_name']);
each explode produces three (3) arrays:
//emails
Array
(
[0] => test123#example.com
[1] => lol123#example.com
[2] => haha#example.com
[3] => blahblah#example.com
)
//first name
Array
(
[0] => Bill
[1] => Jake
[2] => John
[3] => Bob
)
//last name
Array
(
[0] => Jones
[1] => Smith
[2] => Johnson
[3] => Bakers
)
I can get the one array easily like this: for example:
foreach ($emails as $email) {
echo $email;
}
That will echo out the emails. But I want to add $firstname and $lastname into it. for example, I want to echo:
test123#example.com Bill Jones
how can i do it?

Answer 1

foreach can assign a key and value if you use the appropriate syntax:
foreach ($emails as $key => $email) {
echo $email;
echo $firstnames[$key];
echo $lastnames[$key];
}
Next time, consult the manual: http://php.net/manual/en/control-structures.foreach.php as this is shown at the very top.
As Pyromonk pointed out, for is useful in situations where you have indexed arrays:
for ($i = 0, $n = count($emails); $i < $n; $i++) {
echo $emails[$i];
echo $firstnames[$i];
echo $lastnames[$i];
}
