File

File class for handling files.

Examples

$file = new IO\File(Application::getDocumentRoot() . "/file.txt");

File data:

$isExist = $file->isExists(); // true, when file exists

$dir = $file->getDirectory(); // File directory as object IO\Directory
$dir = $file->getDirectoryName(); // File directory

$fileName = $file->getName(); // File name
$fileExt = $file->getExtension(); // File extension
$fileSize = $file->getSize(); // File size in bytes 
$contentType = $file->getContentType(); // Content-type

$createdAt = $file->getCreationTime(); // Date when created, timestamp
$accessAt = $file->getLastAccessTime(); // Date when last accessed, timestamp
$modifiedAt = $file->getModificationTime(); // Date when modified, timestamp

$perms = $file->getPermissions(); // Access permissions for file as decimal number
$perms = substr(sprintf('%o', $file->getPermissions()), -3); // Access permission to file as octal number

Actions with files:

$content = $file->getContents(); // Get file content
$file->putContents("data"); // Writes content into file with replacement
$file->putContents("data", IO\File::APPEND); // Finish writing content to the file's end
$file->readFile(); // Print file content

$file->rename(Application::getDocumentRoot() . "/new_file.txt"); // Move/rename the file
$file->delete(); // Delete the file

Some methods have static variants:

$path = Application::getDocumentRoot() . "/another_file.txt";
IO\File::isFileExists($path); // Check file existence

IO\File::getFileContents($path); // Get file content
IO\File::putFileContents($path, "data"); // Write content into file with replacement
IO\File::putFileContents($path, "data", self::APPEND); // Finish writing content into file's end

IO\File::deleteFile($path); // Delete the file
