Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

"Note:



empty() only checks variables as anything else will result in a parse error. In 

other words, the 

following will not work: empty(trim($name))."



$c = cleanData::GET("test");

if(empty($c)) { 

  /* etc */

} else {

  /* etc */

}

Description:
------------
I have built an MVC (lightweight MVC) now in this is static class ("cleanData") 

with method for (POST, GET, URL) and use addSlashes on them,



the problem is when i use the return data in the empty function

("Fatal error: Can't use function return value in write context")

Test script:
---------------
class cleanData{

  public static function GET($key){

    return addslashes($_GET[$key]);

  }

}



if(empty(cleanData::GET("test"))){

  echo "empty";

}else{

  echo cleanData::GET("test");

}

Expected result:
----------------
if loaded with ?test=1 i should see

1 on output,



if loaded with ?test=, or without test in url i should see 

empty

Actual result:
--------------
Fatal error: Can't use function return value in write context
