Variables within a Class

[Betard]

Can anyone give me some insight on how to use / share variables within a class across the different methods(functions)?

<?php

class myClass {

	var $myVar = 1;
	var $myString = "My number is: ".$myVar;

function testFunc1 () {

	$myVar = $myVar + 1;

	return $myVar;
}

function testFunc2() {

	$myCombo = "What is your number<br />".$myString;

	return $myCombo;		
}
}

$my_test = new myClass();

// below should result in '2' and does not
print($my_test->testFunc1());

// below should result in displaying both sentences with variables inserted, but does not	
print($my_test->testFunc2());

?>

Obviously what I have here is wrong since variables/values are not being seen within the methods/functions.

and I get the following error upon loading this. Unless I comment out line 6 of course in order to get no errors, but I still do not get the intended results:

Parse error: syntax error, unexpected '.', expecting ',' or ';' in /home/mypath/myfolder/test.php on line 6

I'm still pretty new to all of this, but there must be a way to essentially have 'global' variables for this type of situation shouldn't there be?

You need to use the $this variable for "this object". Also, you cannot use operators or functions in a class variable declaration, so you'll need to move your concatenation operation to a constructor.

class myClass {

    var $myVar = 1;
    var $myString;

// constructor:
function myClass() {
    $this->myString = "My number is: ".$myVar;
}
function testFunc1 () {

    $this->myVar = $this->myVar + 1;

    return $this->myVar;
}

function testFunc2() {

    $myCombo = "What is your number<br />".$this->myString;

    return $myCombo;        
}
}

Thanks NogDog, this is exactly what I needed to bump my classes up notch.
