README
Encode a file.
use Jstewmc\EncodeFile\Encode; // set the filename $filename = '/path/to/foo.txt'; // create an ASCII encoded string $contents = mb_convert_encoding('foo', 'ASCII'); // put the contents into the file file_put_contents($filename, $contents); // is the file UTF-32 encoded? mb_check_encoding(file_get_contents($filename), 'UTF-32'); // returns false // create the service // keep in mind, you'll need to implement the Read and Write interfaces // $service = new Encode(new Read(), new Write()); // convert the file to UTF-32 $service($filename, 'UTF-32'); // is the file UTF-32 encoded? mb_check_encoding(file_get_contents($filename), 'UTF-32'); // returns true
PHP Extensions
This library requires PHP's non-default mbstring
extension. If the service is instantiated without the mbstring
extension loaded, a BadMethodCallException
will be thrown.
Dependencies
This library depends on (and provides) two interfaces for a read-file service and a write-file service. The former must implement a __invoke(string $filename): string
method, and the latter must implement a __invoke(string $filename, string $contents): int
method.
The read-file and write-file interfaces MAY be implemented by the jstewmc/read-file and jstewmc/write-file libraries, respectively. For example, in your application, extend Jstewmc\ReadFile\Read
and implement Jstewmc\EncodeFile\Read
:
namespace My\App; use Jstewmc\EncodeFile\Read as ReadInterface; use Jstewmc\ReadFile\Read as ReadParent; class Read extends ReadParent implements ReadInterface { // nothing yet }
From encoding
Keep in mind, it's difficult to detect a string's character encoding. Even PHP's mb_detect_encoding()
function is not perfect. For example, mb_detect_encoding()
will almost never detect Windows-1252 encoding, even if the string actually is Windows-1252 encoded (see Bug #64667 for details).
To prevent erroneously detecting the file's from encoding, you MAY include it as the service's third argument. If the "from" encoding is not given, the library will attempt to detect it.
use Jstewmc\EncodeFile\Encode; $service = new Encode(new Read(), new Write()); // encode file as UTF-8 from Windows-1252 $service('/path/to/file.txt', 'UTF-8', 'Windows-1252');
