calling functions through a variable

[Alchemist]

Hello,

quick question: is it possible in PHP to call a function using a variable this way:

$var = 'validate_email';
Check($var);

$var = 'validate_user';
Check($var);

function Check($var)  {

//dynamically call the functions without using switch


}

function validate_email() 
{ 
 //do something 
}

function validate_user() 
{ 
 //do something 
} 

thanks

I think this is what I need

Yes, of course

$foo = 'printf';
$foo("bar"); 

see also call_user_func

ok, I found everything I needed. i'm posting it here in case someone else has the same question:

if you need to call a function dynamically from within a class just use:

$func = 'validate_email';
$this->{$func}();

function validate_email() {
//do something
} 

no need to use call_user_func

today I learned something new

Actually, if you're using single variable, you can omit { } as well:

$someObj->$methodName(args); 

{ } is for complex expressions

$someObj->{ $foo->bar->getMethodName() } (args);
