Mongodb - PHP - Insert as number

Question

I have a php script that looks like this:

    $contacts["{$firstname}"]    =  $_POST["{$firstname}"] ;
$contacts["{$lastname}"]    =  $_POST["{$lastname}"] ;
$contacts["{$age}"]    =  $_POST["{$age}"] ;


    $collection->insert($contacts);

so this works fine but i all of these values are going into my collection as "fistname", "lastname" and "age" with quotes around all. I want the quotes around first name and last name but i want the age field to insert as a number/integer not a quoted string. How do I make sure that the age field and other numeric fields go into the mongodb/collection as a number?

I was thinking something like: integer -> $_POST["{$age}"] but im sure that's not right. Again im using PHP not the shell. Thnaks.

Thank you for your help.

How can you verify that whatever string $firstname stores is available in $_POST? Use php.net/manual/en/function.isset.php to check. — Aram Kocharyan

First, you don't need all those quotes and braces. Second, try casting the value to an int

$contacts = array(
    $firstname => $_POST[$firstname],
    $lastname  => $_POST[$lastname],
    $age       => (int) $_POST[$age]
);

I'm assuming here that all the $_POST vars have been checked and validated and $firstname, $lastname and $age are all valid array key strings

I tried your suggestion and although i am not getting any page errors it is still inserting as a "" string. Any other suggestions? Thanks.

Ooops, this did work. I actually had an error in my code. Once i fixed the error (int) worked perfectly. Thanks.

Do you know if there is a cheat sheet on these function like (int). Now my problem is i want to keep the decimal and the numbers after the decmal but (int) is stripping everything after the decimal. What function would i use to keep the decimal in there and the number after the decimal. Thanks.

@user982853 (int) isn't a function, it's a type cast. Try (double) for a decimal number

Simple, typecast to integer, and then do the insert:

$contacts["{$age}"]    =  intval($_POST["{$age}"]) ;
$collection->insert($contacts);

You can use http://php.net/manual/en/function.intval.php to convert a string to an integer.
