[RESOLVED] cannot redeclare error

[jimot]

hi.. I have a function like this (taken from adsrotator plugin for wordpress):

<?php
function getads($ad = '') {
  $ad = trim($ad);
  if(strlen($ad) > 0) {
    $ad = ABSPATH . "ads/" . $ad . '.txt';
    if(file_exists($ad)) {
      $ads = file($ad);
      return $ads[rand(0, sizeof($ads)-1)];
    }
  }
}

$adds=getads('ad_160x600');
include ABSPATH . "ads/" . trim($adds);
?>

now when I try to use the function again it always give me this error:

Cannot redeclare getads() (previously declared in......

from what I read on php.net, it's because of the include function. How can I fix this?

Thanks

you may have included it twice. like this:

includes("function.php");
//....
includes("function.php"); 

or like this:

includes("function.php");
//...
function gatad() {
//...
}

Use include_once or require_once to prevent such occurences

yes I did the include twice.. how can I overcome this?

I tried include_once and require_once but still gives the same error.

thanks

[dclamp]

have you tried removing the extra include?

[jimot]

yes, if I use the include only once, that's fine, the one that gives the error is the second include..

[dclamp]

yeah, you dont need to include it more then once.

[jimot]

the problem is I need to include the result of the function..

this is what the function does:
it takes one line randomly from a text file, in which each line in the text file is a URL.

Then, I need to include the URL to my site, and I need to do that more than once. That's why I use include more than once.

thanks

[dclamp]

can you post your code? because you have confused me.

[penagate]

Use require_once to load the code file containing the function and simply call the function whenever it is required. Your code—as posted—does not call the function at all, it merely includes it.

it appears that the error comes from the wordpress plugin ... it's been solved.. thank you all for helping me
