how to search files on server

[fillthemup]

I'm using MySQL and php. How can I search for specific words on a server folder? This will not be a user's search, but purely backend, mainly to find a specific file that has been created, easily.

Is there a script I can load on the server? Otherway?

Thank you.

Lets suppose your searching filename is myfile.txt and you go like this:

$dir = "/etc/php5/";
$search = "myfile.txt";

if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
        while (($file = readdir($dh)) !== false) {
            if($file == $search)
               echo "File found.";
               break;
        }
        closedir($dh);
    }
} 

Umm I am not sure how much your problem i understand.

thank you for your input. before I try start using it, I want to try to clarify myself.

I have many php files on my server in one main folder. I want to be able to search those files. Let's say the words "Thank you. Your form has been submitted." is in one of those files. Instead of trying to figure out which file was created that will display this message for the user, I want to be able to search that entire folder, for those words. Ex., "form has been submitted"...when I type those words into the search feature, I want to be able to see which files containt those words (anywhere in those files). Doing so will thus either bring up a list of all the files with those words, or somehow else showing me which files contain those words.

The searched files are also in various subfolders.

I hope I made myself more clear.

Thank you

Use rajug's example and modify it to the use readfile() function and possiblely preg_match() function. I guessing that would work.

I dont think that it is easier to search all files and their contents of a directory, but you can give a try with some functions like of PHP i.e. glob(), file_get_contents(),fread(), etc. since i dont have any full code of such.
