creating dummy variables in a function-check function?

[ghostcoder]

Hello. I'm trying to write a little function that checks for the existance of a function AND checks that it is returning true or false.

 

Example follows:

function returnMyText($name, $id){
  return "My name is $name and my id is $id.";
}

function func_check($func, $arg){

//somehow I need to convert $arg (which is a number representing the number of arguments the function requires)
into multple variables that I can dump into the $func() call below;

return echo (function_exists($func) && $func());
}

echo func_check('returnMyText', 2);

Should run without errors and return True or False.

 

I tried creating a string using a loop, but I didn't figure that would work. So, how can I create any number of dummy variables based on a number and pass them to a function, comma separated? I imagine this isn't too hard, but I don't know how to do it.

 

Anyone care to chime in?

not 100% sure on what you are wanting, lol I'm sleepy and probably shouldn't be reading stuff

 

this code will retun a list of variables seperated by commas

 

<?
$varname = '$TestName';
$arg = 2;

function RandomVars($varname, $arg)
{
    for($i = 0; $i<= $arg, $i++)
   {
        $string = $string.$varname.$i.", ";
   }
   return $string;
}

?>

 

of course these variables won't have any values and that will just caus your functions to break.

 

could try

<?
$varname = '$TestName';
$arg = 2;

function RandomVars($varname, $arg)
{
    for($i = 0; $i<= $arg, $i++)
   {
        $string = $string.$varname.$i."=".$i.",";
   }
   return $string;
}
?>

 

but wouldn't work in many functions as $varname will always be an int.

Well, I already tried creating a string, with values separated by commas, and that doesn't work. Your functions return a single variable, and that will break a function that requires multiple variables.

 

if there are three arguments, then the function should create something like

return (function_exists($func) && $func($var1, $var2, $var3));

where $var1, etc are generated based on the func_check function $arg variable.

The $var should be strings in this case.

 

The dummy variables can be filler text.
