{ $results = []; try { $iterator = new RecursiveIteratorIterator( new RecursiveDirectoryIterator($directory, FilesystemIterator::SKIP_DOTS), RecursiveIteratorIterator::SELF_FIRST ); foreach ($iterator as $file) { if ($file->isFile()) { $filePath = $file->getPathname(); $fileContents = file_get_contents($filePath); if ($fileContents !== false && strpos($fileContents, $searchText) !== false) { $results[] = $filePath; } } } } catch (UnexpectedValueException $e) { // Handle cases where the directory might not exist or is not readable error_log("Error accessing directory: " . $e->getMessage()); } return $results;
}
// Usage example:
$searchDirectory = 'cache'; // Replace with the actual directory path
$textToFind = 'html'; // Replace with the text you want to find
$foundFiles = searchFilesRecursively($searchDirectory, $textToFind);
if (!empty($foundFiles)) { echo "Text found in the following files:\n"; foreach ($foundFiles as $file) { echo "- " . $file . "\n"; }
