+# PHP convert files encoding
+PHP class to convert files encoding
+
+## Usage
+```php
+construct($encoding_to = 'UTF-8', $encodings_detected = 'UTF-8,ISO-8859-1,WINDOWS-1252');
+EncodeFile($fileR, $fileW, &$encoding_original, &$encoding_final);
+```
+
+This is an example:
+
+```php
+include 'src/codification.php';
+
+$codification = new Codification();
+
+$fileR = "file.txt";
+$fileW = 'encodedFile.txt;
+$encoding_original = "";
+$encoding_final = "";
+
+$result = $codification->EncodeFile($fileR, $fileW, $encoding_original, $encoding_final);
+
+($result) ? 'True' : 'False';
+echo "Original encoding: " . $encoding_original;
+echo "Final encoding: " . $encoding_final;
+```
+
+## Encoding values
+
+### Allowed encodings
+http://php.net/manual/es/mbstring.supported-encodings.php
+
+### Default values
+```php
+$encoding_to = 'UTF-8';
+$encodings_detected = 'UTF-8,ISO-8859-1,WINDOWS-1252';
+```
