@NogDogFeb 02.2011 — #It might also be a scope issue if either the variable is declared within a function definition, in which case it is only local to that function.
PS: you could use require() instead of include() to find out if the file is really being included or not. @NogDogFeb 03.2011 — #[b]global[/b] may be a quick fix, but it's generally a non-optimal solution, as it closely couples the function to the rest of the application, which can lead to ugly bugs and limit re-usability. Without a good feel for what all is going on in this case, I'm not sure what the better solution is, but generally you want to feed variables [i]into[/i] a function via the function's arguments (a.k.a. "parameters") and get them [i]out[/i] of the function either by [b]return[/b]ing them, or via a "pass by reference" function parameter.@NogDogFeb 08.2011 — #
But that's just typing: you can type a variable name 20 times in a minute or two if you're a decent typist (or less with a good editor/IDE with auto-completion), which beats the heck out of debugging for hours/days to avoid it, while also avoiding the use of global variables which are frowned upon anyway. ?
simple php variable question – variable definitions being lost
I am sure there is a simple solution to this, but I have found that when I define a variable in one place that it isn’t always available within the rest of the page. For example:
[CODE]
<?php include(“includes/header.php”); //within header $myVariable is declared (by $myVariable = 2;) ?>
<html>
<head>
</head>
<body>
<p>
my variable = <?php echo $myVariable ?>
</p>
</body>
</html>
Is there a way to declare a variable inside an include and have it remembered by the rest of the page that the include is inserted into?

@NogDogFeb 08.2011 — #It didn't work when i tried it. I will double-check it and see if I had an error. Likely I will end up breaking down and passing the variable with the function call (which is what I was trying to avoid since I have to call the function about 20 times).[/QUOTE]
