I'm starting learning classes in PHP. I coded that:
class User {
function getFbId($authtoken) {
}
function getFbFirstName ($authtoken) {
}
}
What I want to do is something like that: $user=new User($authtoken); And pass the $authtoken to the class. It's possible to define that when starting the class. It's possible to retrieve that value inside a function of that class?
To use the variable passed in constructor throughout your class, you can create a class level variable like this:
class User {
private $tokenID = NULL;
function __construct($tokenID){
// store token id in class level variable
$this->tokenID = $tokenID;
}
function someFun($authtoken) {
echo $this->tokenID;
}
}
You need to create the constructor in order to do that:
class User {
function __construct($tokenID){
// do something with $tokenID
}
function getFbId($authtoken) {
// code
}
function getFbFirstName ($authtoken) {
// code
}
}
Note:
If you are using PHP4, a constructor can be created with a function name same as that of class like:
class User {
function User($tokenID){
// do something with $tokenID
}
function getFbId($authtoken) {
// code
}
function getFbFirstName ($authtoken) {
// code
}
}
Now you can do something like:
$user = new User($authtoken);
You are looking for contructors. See http://www.php.net/manual/en/language.oop5.decon.php Or http://www.codewalkers.com/c/a/Programming-Basics/ObjectOriented-PHP-Constructors-and-Destructors/ for a walk through.
