在foreach循环中的PHP foreach循环

I'm trying to do a foreach loop inside a foreach loop.

I have a form where the user type in some text and hit send. On the server site I loop through an array with email addresses and send out the text message.

Now I also want the user to be able to use variables in the textarea, like $name. So my loop should first loop through the emails, and then str_replace the userinput $name variable, with the names in my array.

The loop works fine with the email part ($tlf), but not the replace $name part.

Could some spot what I am doing wrong?

$message = stripslashes(strip_tags($_POST['message2']));
$tlf=array("name1","name2");
$test=array("mname1", "mname2");
$subject = "Hello world";
$from = "me@gmail.com";
$headers = "From: $from";

foreach($tlf as $name){
    $to = $name. "@gmail.com";
    foreach($test as $navn){
        $message = str_replace('$navn', $navn, $message);}
    mail($to,$subject,$message,$headers);
}

Thanks a lot.

EDIT: The output is an email sent. Say the user type in "hello $name". I want it to first loop through the $tlf array, in this case creating 2 emails. This goes in as $to in the first loop. This works.

Now the next loop should recognize the user input "hello $name" and loop through the $test array replacing the user $name variable.

The output would be 2 emails send.

1. Mail output: to: name1@gmail.com message: hello mname1

2. Mail output: to: name1@gmail.com message: hello mname2

Let me know if I need to explain better, its hard for me to explain sorry.

Is this what you want?

$message = stripslashes(strip_tags($_POST['message2']));
$tlf=array(
            array("email" => "name1", "name" => "mname1"),
            array("email" => "name2", "name" => "mname2")
          );
$subject = "Hello world";
$from = "me@gmail.com";
$headers = "From: $from";

foreach($tlf as $contact){
    $to = $contact["email"] "@gmail.com";
    $replacedMessage = str_replace('$navn', $contact["name"], $message);
    mail($to,$subject,$replacedMessage,$headers);
}

When you do the following:

str_replace('$navn', $navn, $message)

Then all literal occurences of $navn will be replaced (the first, the second, the third, ...). So running through that loop a second time can't possibly replace anything more.

You will need to define two placeholders, or make some distinction, or use preg_replace_callback if you want to declare in which order (or other logic) the possible replacement strings are applied.

If you had told us (but you haven't) you only wanted to replace the first occurence in each iteration, then a normal preg_replace(.., .., .., 1) would work.
