[Resolved] strpos issues

[helz]

whenever i have tried to use strpos it has worked successfully,
but now it doesnt seem to want to work...
i use this code to display files in a directory:

if (is_dir($dir)) {
   if ($dh = opendir($dir)) {
      while (($file = readdir($dh)) !== false) {
         if ($file!="." && $file!=".." && substr($file,-4)!=".php"){
            echo $file;
         }
      }
   }
   closedir($dh);
}

it goes through the directory and outputs the files onto the screen
but now i want to test $file to see if a certain string is inside the filename using:
strpos($file,"YAC");
there is a file called: YAC_LEAGUE.htm
but strpos returns false even though it exists...

i know strpos is case sensitive, but i thought that it was only
sensitive to what case the needle is.

any ideas?

Tried [man]stristr[/man]? It's more what it's made for...

I dunno if strpos is supposed to do this that well or not ... I'll jog over to the manual and see. Wonder if you caught a bug?

Nah, of course. Since the file starts with "YAC", strpos is returning position zero, and you're testing without calling "===" ... check the manual.

But I think stristr is still more what you want.... 😉

try using
if(strpos(strtolower($file),"yac")) !== FALSE) {
echo "found file";
}

thanks for that, i tend to use strpos because i just want to know
whether it exists, where as i see in the manual. strstr/stristr return part of the string.

thanks again

just one more thing,
if i wanted to check for two things:
does "a" or "b" exist in $string.
can that be done in a single strpos with an array as the needle?
or would i have to use two strpos's?
