How do I cycle through REQUEST and use dynamic variable naming? PHP ! :)

I have a form that submits details of multiple people i.e in the $_REQUEST I get :

title1 = Mr, 
first_name1 = 'Whatever', 
surname1 = 'Whatever', 

title2 = Mr, 
first_name2 = 'Whatever', 
surname2 = 'Whatever'

There's obviously more but this explains the situation. There could be ten people being submitted and therefore it would go up to title10, first_name10, surname10...

I have been trying to use:

for ($x = 1; $x < 4; $x++) {

    $a = new applicant();
    $a->title       = $_REQUEST['title'+$x];
    $a->first_name      = $_REQUEST['first_name'+$x];
    $a->surname         = $_REQUEST['surname'+$x];
    $a->Save();
}

However it appears that you cannot do this +$x bit. I know there is a way around it since I remember doing this ages ago yet I don't have my code 开发者_如何转开发at work :/

Any ideas guys?

PHP uses . for concatenating strings, and + for adding numbers; this is different from some other languages which use + for both. Possibly confusing, but unlikely to change.

'title' + $x will try to add the parts as if they were numbers, casting if necessary.

'title' . $x should do what you seem to be looking for.

String concatenation in PHP uses the operator . not +. For example: $_REQUEST['title' . $x];

You can use the same attribute name in your HTML form for mulitple inputs like so:

<input name="title[]" />
...
<input name="title[]" />

Which when submitted to the PHP script will be available in the GET/POST as an array already.

you may try this:

$a = "first part";
$b = "second part";

$c = ${$a.$b};

or something like

$c = $_REQUEST[${$a.$b}];

Anyway, you got the idea.
