table return values & strpos()

R3D

Hi,

I'm having the following problem, after I have pulled out data from my database tables (MySQL) then it seems the php5 strpos() function fails to get results.

I'm using strpos() to find tags in the format like to wrap html code around it and then display it, everything works fine when I load the data from txt files. But when I use the same data from the table then strpos() just runs over the tags in the string and does not find them.

What is the diffrence about a string that gets contents from out fread() or from a database table? I'm confused.

Does anyone knows why this happens and/or how I can solve this?
Thanks at front.

why strpos? why not either regex (preg_replace) or str_replace?

Hi, I'm using str_replace() to, but first i need to extract the data between the tags, to do that i need to get the start and end positions, eg using strpos().

Here is my function for finding and replacing multiple image tags in a string;

function Convert_IMG($msg)
{
$tag1 = '[IMG]';
$tag2 = '[/IMG]';
$Run = true;
while ($Run) 
{
    $pos1 = strpos($msg, $tag1);
    $pos2 = strpos($msg, $tag2);
    if($pos1==true){
	  if($pos2==true){
         $img = substr($msg, $pos1 + strlen($tag1), $pos2 - strlen($tag1) -$pos1);              

         $img_new = '<img src="' . $img . '" alt="' . $img . '" />';
         $img_old = $tag1 . $img . $tag2;
         $msg = str_replace( $img_old, $img_new, $msg);
      }else{
         $Run = false;
      }
	}else{
	  $Run = false;
	}
}
return $msg;
}

Wich never made any problems before, it always worked, it is just now when i'm parsing a string that I pulled out a table then the strpos() always is returning false, even tough the tags are in the parsed string.

start echoing out the bits to ensure that you have the correct var you are testing and it has the values you expect....
