Need PHP help - Conditional functions

Could someone please explain this to me? I have read about it but still do not understand it.

 

If you mean things like if, else, etc... Then a quick Google search will provide you with a ton of basic tutorials. The syntax is quite easy to follow. Same solution if you're talking about conditional loops.

 

what's a conditional function?

 

That's sort of what I'm asking.

 

Here try this If then and Math..

 

Link didn't work.

 

try again.. works fine

 

I tried again, I restarted and tried again, for some reason my browser is not showing your site, though it loaded, and I can see the source code.

 

OMG its not working in IE.. luckily other pages are.. still its not good..

I guess try using FF..

 

if ( !function_exists('functionName')){
  function functionName(){}
}

PHP:

 

Oh, ok that makes sense now, thanks.

 

Chemo is on the right track, I think. I looked at this thread a while ago and didn't know what 'conditional functions' were, so I steered clear

But yeah, Chemo makes a good point and he jolted my memory: it may also be in reference to using call_user_func ( http://ca3.php.net/manual/en/function.call-user-func.php ) whereby you can use a variable to define the name of the function to call.

 

There's always the php website, www*php.net

if(statement) {
$result = Function_A();
} else {
$result = Function_A();
}

or

function testFunction($var) {
if($var==statement) {
//do somthing
//return something
} else {
//do somthing else
//return something else
}
//or return something here
}
