Hello,
According to the PHP manual on functions (http://www.php.net/manual/
en/language.functions.php):
"In PHP 3, functions must be defined before they are referenced. No
such requirement exists since PHP 4. Except when a function is
conditionally defined..."
If that is true then why does the following not work as I expect?
I expect the result to be "Function was called!" but it actually is
"Function test() does not exist!".
File: a.php
<?php
if (function_exists('test')) {
echo test();
}
else {
echo "Function test() does not exist!";
}
require 'b.php';
?>
-------------------------------
File: b.php
<?php
require 'c.php';
?>
-------------------------------
File: c.php
<?php
function test() {
return "Function was called!";
}
?>
