How do I use preg_replace to replace a space (" ") with a comma (",")?
i am using:
preg_replace('/ /', ',', $string).
this isn't working.

Hi,
The replaced string is returned by the function. This works.
$str = "test test2";
$str2 = preg_replace('/ /', ',', $str);
If your are doing simple replacements like this you should use
str_replace() it's much faster!
$str = "test test2";
$str2 = str_replace(' ', ',', $str);

Simply do a
>while ($file = readdir($handle)){
and make your directory current inserting
chdir('c:\apache\htdocs');
just before the line where you finally check success of the fopen using
> if ($handle_file = fopen ($find_file, "r")) {
> ...
> }
> else print 'Unable to open file '.$find_file;
because most likely c:\apache\htdocs isn't the current dir when
executing the fopen (opendir does not make a dir current to fopen).
Alternately you might want to feed the complete pathname
(including dir) to the fopen.
Besides: in a case where you know the filename in advance you might
leave out the directory search completely, thus saving a lot of execution
time.

I think you have the problem in:
$handle_file = fopen ($find_file, "r");
while (!feof ($handle_file)){
$buffer = fgets($handle_file, 4096);
echo "$buffer";
}
Right? Well, I think the next code could help you:
";
}
?>
This prints each line of the text file. I hope it helps you.
