Referencing external functions from functions & classes

[fintan]

Hi can someone show me the proper way to call an external function from within a fuction or a class?

Would it be something like this?

$test = myfunciton($var1,$var2);

function testing($variable1, $test){

do something...

}

Thanks

You just call it like you would normally call any other PHP function.

function squareIt($n) 
{ 
 return $n*$n; 
} 
function doSomeMath($n) 
{ 
 return squareIt($n); 
} 
print doSomeMath(5); // prints 25

Thanks coopster I'd assume it's the same for classes with internal and external functions?

Did you try it?

function squareIt($n)  
{  
 return $n*$n;  
}  
class myMathClass 
{ 
 function doSomeMath($n)  
 {  
   return squareIt($n);  
 } 
} 
$math = new myMathClass(); 
print $math->doSomeMath(5); // prints 25 
exit;

The answer is yes, it works ;)
