Re: [PHP] Function Declared in Included File Not Being Found

Files are included/required at run-time. As such, the function has not
been declared when you make reference to it since the require occurs
later. Move the require to the top. As a test, feel free to explicitly
define the function at the bottom without using a require.

Cheers,
Rob.

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!";
}

?>
