Re: Can i take the variable name in a function?

Check this out: http://www.php.net/manual/en/functions.arguments.php Specifically this example: Making arguments be passed by reference By default, function arguments are passed by value (so that if you change the value of the argument within the function, it does not get changed outside of the function). If you wish to allow a function to modify its arguments, you must pass them by reference. If you want an argument to a function to always be passed by reference, you can prepend an ampersand (&) to the argument name in the function definition: *Example 17-6. Passing function parameters by reference* <?php function add_some_extra(&$string) { $string .= 'and something extra.'; } $str = 'This is a string, '; add_some_extra($str);

echo $str;    // outputs 'This is a string, and something extra.'

?> I think that does what you want? Andy On 10/11/06, Jônata Tyska Carvalho <jonatatyska@gmail.com> wrote:

How can i take the variable name inside a function, ex: definition: function example( $ex ){ echo "Variable Name is $ex "; // how to do this? } use: example($ball); output: Variable Name is ball; another: example($sportCar); output: Variable Name is sportCar; is that possible?
