recursively reading files from directories and replacing string

[kwylez]

The purpose of the script is to search recursively through the current directory open of any files, read if the files contain a certain string and if so replace it.

However, this doesn't work.

Listing the directories and files is not a problem, but doing doing the string matching and replacing doesn't work at all.

any help would be appreciated.

//begin code
#!/usr/local/bin/php
<?

$dir = '.';
$handle = opendir($dir) or die("Couldn't open the directory");

if(is_dir($dir)) {

while(false !== ($file = readdir($handle))) {

   if($file !=="." && $file !=="..") {

	   if (is_dir($file) ) {

			$newDir = $file;


			echo "Directory is: ".$newDir."\n";
			echo "Files within are: \n";

			$newHandle = opendir($newDir) or die("Failed opening Subdirectory: ".$newDir);

			while(false !== ($newFile = readdir($newHandle))) {

			if($newFile !== '.' && $newFile !=='..') { echo $newFile."\n"; }

			if($newFile !="." && $newFile != ".." ) {

			$fd = @fopen($newFile, 'w') or die("Error opening the file");

			$contents = @fread($fd, filesize($newFile)) or die("Error Reading the file\n $newFile\n");

			if(preg_match('/mail3/', 'mail', $contents)) {

			$contents = preg_replace('/mail3/', 'mail', $contents);

			echo "Succesully updated file\n\n";

			fclose($fd) or die("Couldn't close the file");

																		}
																	}
																}
															}
													   	 }
												      }
												   }

			closedir($handle);

?>

what error are you getting? Have you tried narrowing down to a certain line?

Anyway, this may be a problem:

$fd = @fopen($newFile, 'w') or die("Error opening the file");

You have to open with 'r', not 'w', if you want to read.
