[RESOLVED] Simple Function I want to echo

[spighita]

Hello Everyone,
I've been away for quite some time now and have forgotten a lot of php. I've started programming again and stuff is coming back to me.

I have this simple php code I need to see how to get it going

$a="apple";
function fruits(){
if($a=='apple'){
return "Yesssssssssss!!!!!!";
}//end if
}//end function fruits
echo fruits();;

What's wrong with this?

Thanks for your taking your time in reading this.

$a does not exist in the function's scope. A possibly appropriate solution in this case is to use a parameter, e.g.,

<?php
function fruits($x) {
    if ($x == 'apple') {
        return 'Yesssssssssss!!!!!!';
    }
    return '';
}

$a = "apple";
echo fruits($a);

as laserlight is right on

here a few more options

$a = 'apple';


function fruits()
{
   global $a; // global $a to the function scope.

if($a == 'apple')
{
   return 'yesssssss!';
 }

 else
 {
     trigger_error('Nooooo!');
     return(false); // return false on failer
  }

 return(false); // return if nether condition apply's
}

function fruits()
{
	$a = 'apple'; // defining $a in function scope.

if($a == 'apple')
{
	return 'yes';
}

else
{
	return 'no';
}

   return(false);
}

Laserlight.. I remember the first time you helped me 8 years ago. Thank you again. You are a legend in my book.

Jgetner, thanks for the alternate solutions. I had forgetten about the global variable and thanks for bringing it back.
