Counting

[xwin]

Is there a way to count all of a certain character in all of the files in a defined folder? I know how to do it for one individual file, but is there a way to do it for a folder, without defining the files contained in it?

[altexis]

have a look at the examples for the readdir() function in php.net

Um. I read it over.

So, this will open all the files:

<?php
if ($handle = opendir('/path/to/files')) {
    echo "Directory handle: $handle\n";
    echo "Files:\n";

/* This is the correct way to loop over the directory. */
while (false !== ($file = readdir($handle))) { 
    echo "$file\n";
}

/* This is the WRONG way to loop over the directory. */
while ($file = readdir($handle)) { 
    echo "$file\n";
}

closedir($handle); 
}
?>

Then this is my counting script.

$cont = join('', file("$file"));
$count = substr_count($cont, '|');
print floor($count);

Would I just make it $file?

How do I connect the two?

[altexis]

if your existing code

$cont = join('', file("$file"));
$count = substr_count($cont, '|');
print floor($count);

...already works, then just add it to the one you found from php.net:

$count = 0;
if ($handle = opendir('/path/to/files')) {
    while (false !== ($file = readdir($handle))) {
        if ($file!="." && $file!=".." && !is_dir($file)) {
            $cont = join('', file("/path/to/files/$file"));
            $count += substr_count($cont, '|');
        }
    }

closedir($handle); 
}
print floor($count);

just note that you need to take care of the files with name "." and ".." and also reject the directories

Messed around with it, doesn't work. 🙁

This is what it looks like right now:

$count = 0;
if ($handle = opendir('data/forum . $id')) {
    while (false !== ($file = readdir($handle))) {
        if ($file!="." && $file!=".." && !is_dir($file)) {
            $cont = join('', file('data/forum . $id . /$file'));
            $count += substr_count($cont, '|');
        }
    }

closedir($handle); 
}
print floor($count);

Any help?

[altexis]

is there any error message you have? ...or what does not work exactly?

Apparently it can't get to the right directory..

The directory I want is in /data, the directory it's in is /includes.

The error output is:

Warning: OpenDir: No such file or directory (errno 2) in /home/virtual/site18/fst/var/www/html/forums/includes/forumindex.php on line 43
