Using class object and method in function

Hello,
I try to create and use a class object instance and its method inside a function.
For example I have the following code, but it not works:

Code: Select all

class clsTest { protected $prop =''; function __construct($prop){ $this->prop = $prop;var_dump($prop); } public function method($str){ return $this->prop .' / '. $str; } } //Receives $prop-argument for object-instance, $str-argument for method() function fun(){ $str ='Text to method.'; $ob = new clsTest($prop); $re = $ob->method($str); return $re .' / Text from function.'; } $prop ='Prop for class.'; echo fun();
It shows this error:

Code: Select all

Notice: Undefined variable: prop

Hello,
Pass to the function the arguments needed for class.
You can use one of the following examples:
1.

Code: Select all

class clsTest { protected $prop =''; function __construct($prop){ $this->prop = $prop; } public function method($str){ return $this->prop .' / '. $str; } } //Receives $prop-argument for object-instance, $str-argument for method() function fun($prop, $str){ $ob = new clsTest($prop); $re = $ob->method($str); return $re .' / Text from function.'; } $prop ='Prop for class.'; $str ='Text to method.'; echo fun($prop, $str); // Prop for class. / Text to method. / Text from function.
2.

Code: Select all

class clsTest { protected $prop =''; function __construct($prop){ $this->prop = $prop; } public function method($str){ return $this->prop .' / '. $str; } } //Receives $ob-object-instance, $str-argument for method() function fun($ob, $str){ $re = $ob->method($str); return $re .' / Text from function.'; } $prop ='Prop for class.'; $ob = new clsTest($prop); $str ='Text to method.'; echo fun($ob, $str); // Prop for class. / Text to method. / Text from function.
