copied!<p>Here is my solution:<br></p> <pre><code><?php class FileGrep { private $dirs; // Scanned directories list private $files; // Found files list private $matches; // Matches list function __construct() { $this->dirs = array(); $this->files = array(); $this->matches = array(); } function findFiles($path, $recursive = TRUE) { $this->dirs[] = realpath($path); foreach (scandir($path) as $file) { if (($file != '.') && ($file != '..')) { $fullname = realpath("{$path}/{$file}"); if (is_dir($fullname) && !is_link($fullname) && $recursive) { if (!in_array($fullname, $this->dirs)) { $this->findFiles($fullname, $recursive); } } else if (is_file($fullname)){ $this->files[] = $fullname; } } } return($this->files); } function searchFiles($pattern) { $this->matches = array(); foreach ($this->files as $file) { if ($contents = file_get_contents($file)) { if (preg_match($pattern, $contents, $matches) > 0) { //echo $file."\n"; $this->matches = array_merge($this->matches, $matches); } } } return($this->matches); } } // Usage example: $fg = new FileGrep(); $files = $fg->findFiles('.'); // List all the files in current directory and its subdirectories $matches = $fg->searchFiles('/open/'); // Search for the "open" string in all those files ?> <html> <body> <pre><?php print_r($matches) ?></pre> </body> </html> </code></pre> <p>Be aware that:<br></p> <ul> <li>It reads each file to search for the pattern, so it may require a lot of memory (check the "memory_limit" configuration in your PHP.INI file).</li> <li>It does'nt work with unicode files. If you are working with unicode files you should use the "mb_ereg_match" function rather than the "preg_match" function.</li> <li>It does'nt follow symbolic links</li> </ul> <p>In conclusion, even if it's not the most efficient solution at all, it should work.</p>
