Fatal error: Cannot redeclare header()

clinicalbear · June 25th, 2012, 01:04 PM

Hi everyone, I have a problem to call external functions.
I wrote this:

Code:

<?php 
function header(){
?>
<!DOCTYPE html>
<html>
<head>
</head>
<?php
}
?>

in a php file named header.php
in the index page i've included the function in this way:

Code:

<?php 
include_once 'tiles/header.php';

header();
?>

when I watch this page on the browser I get this error:

Code:

Fatal error: Cannot redeclare header() in /var/www/vhosts/../header.php on line 9

any suggestion on how to solve this?

Ok, solved, I just changed the function name from header() to head() and now no problems.
if anyone knows why please post the reason so that I can know at least why...

Greetings,

Because there is already a php function called 'header' and you were creating another one hence the 'cannot redeclare' error.

thank you UseLess, I thought something like this and you confirmed it.
