Quick PHP OO question

[ryan_b83]

Hello, I was wondering if I instantiate a class which has class varibles in it how could I access just the variable in an outside method rather than re-instantiating the class within the method. Here is an example

class siteBase{
 function siteBase{
 $this-var = "123";
 }
}
class siteUtilities{
 function someMethod{
 //How would I access $siteBase->var without having to instantiate it?
 }
}
$siteBase = new siteBase();
$siteUtilities = new siteUtilities();
$siteUtilities->someMethod();

[PHP_Chimp]

class siteUtilities extends siteBase{
function someMethod{
//How would I access $siteBase->var without having to instantiate it?
}
}

Then you can overload whatever you want. Have a look at [php.net...] and [php.net...] for more specific info on class constants.

You can't access a variable declared inside a function. The function would either have to return the value stored in the variable, or the variable should be made a class attribute, in which case it can be accessed statically, or via inheritance...

You should be able to make the variable constant, too, in your class, then use the scope resolution operator to access it:

class siteBase {
const var = 123;
...
}
#
echo siteBase::var; #uses scope resolution operator
