Cannot redeclare function??!!

Anon

Hello. Weird one here - for me.

I have a page (000001.php) which is calling 3 includes to do the following:
- connect to db
- get formatting instructions
- grab a template in which to display

The page is displaying fine and all seems to be working OK, but here's the issue:

For some of my pages (just some!) I get a PHP error message at the bottom of the page:

Fatal error: Cannot redeclare webcontent_connect() in db_functions.php on line 14.

Webcontent_connect is a function in the include file db_functions, which handles my db access protocols, as you may have guessed.

I'm only calling it once, and all db_functions contains is one function - webcontent_connect.

How could this be happening?
Why?
Can anyone help?

Thanks.

Maybe one of the other pages you're including is including db_functions.php again, and you've forgotten that it was there?

Anon

checked for that ... second thing I looked at.

both of the other functions are really stripped down to only do what they need to do.

thanks though.

Can you include the lines of code that produces the error so we can take a look?

Thanks for the interest ... the problem has disappeared. So I am crossing my fingers and hoping everything's OK.

Needless to say, a bug that I can't figure out, can't properly trace, don't understand, and pulls a card-trick disappearing act on me is not helping me sleep at nights.

I had the same problem. It disappeared when I replaced "require()" with "include". Now it's OK.

I encountered the same problem. I put all the functions into common.inc.php, and other files called it using: require("common.inc.php"); Sometimes the redeclare error appears, so strange.

My problem solved when I use "<?php " instead of "<? "! So excited!

//----make pulldown box from an array-----------------------------------------//
//----2 lists (A)=Value/Id (😎=Text on the List ------------------------------//
//----------------------------------------------------------------------------//
function pulldown($name,$text,$value,&$elements,$class) {
//---- main loop will use, <option value="xx">yy</option>
function print_opt ($opt, $key, $sel) {
list($val,$pr) = $opt;
if ($val == $sel) {
echo "<option value=\"$val\" selected>$pr</option>\n";
} else {
echo "<option value=\"$val\">$pr</option>\n";
}
}
$lsize = sizeof($elements); //-- get the number of elements in array
echo "<p class=\"$class\">$text\n";
echo "<select class=\"$class\" name=\"$name\">\n"; //-- start select with name
array_walk($elements,'print_opt',$value);
reset($elements);
echo "</select></p>\n";
}

I hope this code snippet looks normal. 😉
Second Call to function pulldown
generates cannot re_declare print_opt error?

However moving the function outside of the original has done it, because I'm not using any of the main functions variables as globals in the sub function its okay,
but apparently php's nested function support is literal, meaning that if a function foo{ } contains in it the word function xxx() that call will declare xxx as a function, any subsequent calls to function foo, will generate errors "Cannot Redeclare".

Notes for other posters on topic

php4 has

require_once
include_once for those who are getting those
errors.
