[GD77]

Hello:

Trying to make variables global inside a function dynamically:

 

foreach($_POST as $ke => $val) {

 

  $$ke= trim($_POST[$ke]);

global $$ke;

 

}

 

then I call that function inside another one to be used the global... not working how to fix it plz. Thanks

why on earth would you want to set a user submitted value as a global? why are you even using globals?

[GD77]

you are right and m not going to use but when I need to set a variables as globals multiple vars what s wrong with my code so it s not doing it?

Well, rather than help you find the solution to your problem, do you mind us trying to show you a better alternative to this?

 

Also, please include more of your code.

yes I m opened to all alternatives and this is the code nothing more:

function tst() {
  foreach....
}

Your function should return values if you need them outside of the function.

Arbitrarily setting program variables, named directly from externally submitted data, without any limits/restrictions or validation of the name, would allow a hacker to set any of your program variables to anything he wants.
