need help with ereg function

[mikewooten]

i'm using the datecheck () ereg function inside of a while loop and its giving me this error.
here's the function:

PHP:

function datecheck($intext) { 
   $result = ereg("([0-9]{1,2})-([0-9]{1,2})-([0-9]{4})", $intext, $trashed); 
   if ($result) { $isamatch = ""; } else { $isamatch = "No - NOT A MATCH"; } 

 echo("\"$intext\" $isamatch<br>\n");   

}

--------------------------------------------------------------------------------

here' s the error:

Fatal error: Cannot redeclare datecheck() (previously declared in /home/username/public_html/folder/thanks2.php:332) in /home/username/public_html/folder/thanks2.php on line 332

when i take the function outside of the loop, the form on the page just keeps copying itself all the way down the page, i'm guessing it has something to do with the loop, but i'm not sure whats going on with it, and why its giving me this error if
i don't have 2 functions with the same name? also i don't have an include file with the same function in that file.
can anyone tell me how i could fix this so that i don't get this error?

thanks

You have this function inside of a loop? The error you're getting is because you can only define a function once. The error says you're trying to declare it multiple times and PHP hates that. This leads me to believe you have the loop and then the function definition in that loop. You need to put the function out on its own, and then CALL the function from your loop (versus defining it in the loop). Give that a shot.

would i CALL the function from my loop?
would it be the same as i am calling it inside of the loop?
thanks

You can't define the function from within your loop, which is what I think you're doing, but you haven't posted all the code. Calling a function is just a matter of doing [function name]([param 1], [param 2], ...).

There are some basic jargon that you need to know when dealing with functions:

1. To declare a function is to write the implementation of the function.
   e.g.

   function myFunction($arg1, $arg2) {
   	return $arg1 + $arg2;
   }

myFunction is the name of the function, and $arg1 and $arg2 are the function's arguments (parameters).

2. To call a function is to use it in your code.
   e.g.

   echo myFunction(2, 3);

3. You can only declare a function of a given name once in your script.
   But you can call it as many times as you like.

NB: it some other programming languages, it is possible to declare more than one function of a given name in the same program, i.e. function overloading.
In these cases, there is usually some way to determine which function declaration should be used when calling the function.
PHP4 does not support function overloading.

should i post all the code that i have for the page i'm working on for you to see what i'm doing wrong?

[mikewooten]

i put the functions on its own outside of the loop and when i go to run the page and view it.
the form on the page just keeps copying itself all the way down the page. i'm not sure whats going on with it.
how can i get the page to only display the form once and not have many copies of the form.
can someone please help?

here's the code i am using:

session_start();

require_once('bookmark_fns.php'); 

$username = $HTTP_POST_VARS['username'];
$passwd = $HTTP_POST_VARS['passwd'];

if ($username && $passwd)
{
    if (login($username, $passwd))
    {
      $HTTP_SESSION_VARS['valid_user'] = $username;
    }  

    else
    {
      do_html_header('Problem:');
      echo 'You could not be logged in. 
            You must be logged in to view this page.';
      do_html_url('login.php', 'Login');
      do_html_footer();
      exit;
    }
