[SOLVED] No output?

[The Little Guy]

myClass.php:

<?php
class myClass {
     public $myVar = '';

     function myFunction($value){
          return $myVar = $value;
     }

     function useVars(){
          echo $myVar;
     }
}
?>

 

<?php
include 'myClass.php';
$tempC = new myClass();
$tempC->myFunction('I am a cat');
$tempC->useVars();
?>

After running this file, the output would be blank why?

Return values in functions, don't echo them!

 

<?php
class myClass {
     public $myVar = '';

     function myFunction($value){
          return $myVar = $value;
     }

     function useVars(){
          return $myVar;
     }
}
?>

[The Little Guy]

it still does nothing

[PFMaBiSmAd]

return $myVar = $value;

should be -

 

$this->myVar = $value;

[The Little Guy]

would I do this->$myVar to set the variable to the new value?

You also need to change -

 

echo $myVar;

 

to this -

 

echo $this->myVar;

This is from the actual file:

 

Fatal error: Cannot access empty property in /home/.marble/ryannaddy/phpsnips.com/phpMagick/phpMagick.php on line 39

<?php
class phpMagick {	
public $input = '';
function set_input($ipt){
	return $this->$input = $ipt;  // Line 39
}
}
?>
