I created this library, to avoid having to throw exception in my code when I use the file functions.

Folded is a constellation of packages to help you setting up a web app easily, using ready to plug in packages.

• folded/action: A way to organize your controllers for your web app.
• folded/config: Configuration utilities for your PHP web app.
• folded/crypt: Encrypt and decrypt strings for your web app.
• folded/exception: Various kind of exception to throw for your web app.
• folded/history: Manipulate the browser history for your web app.
• folded/http: HTTP utilities for your web app.
• folded/orm: An ORM for you web app.
• folded/routing: Routing functions for your PHP web app.
• folded/request: Request utilities, including a request validator, for your PHP web app.
• folded/session: Session functions for your web app.
• folded/view: View utilities for your PHP web app.

• Will throw an Exception if an error occured while using the functions
• Have the exact same signature as the native functions

• PHP version >= 7.4.0
• Composer installed

In your root folder, run this command:

composer required folded/file

• 1. Open a file
• 2. Close a file
• 3. Delete a file
• 4. Write a CSV row to a file
• 5. Read a CSV row from a file
• 6. Rename a file
• 7. Write on file

In this example, we will get an opened file.

use function Folded\openFile; $file = openFile("path/to/file.txt", "r");

In this example, we will close an opened file.

use function Folded\openFile; use function Folded\closeFile; $file = openFile("path/to/file.txt", "r"); closeFile($file);

In this example, we will delete an existing file.

use function Folded\deleteFile; deleteFile("path/to/file.txt");

In this example, we will write a CSV row in a file.

use function Folded\openFile; use function Folded\addCsvRowToFile; $file = openFile("path/to/file.csv", "w"); addCsvRowToFile($file, ["foo", "bar"]);

In this example, we will get a CSV row from a file. Subsequent calls will get the next rows from the file.

use function Folded\openFile; use function Folded\getCsvRowFromFile; $file = openFile("path/to/file.csv", "r"); $firstRow = getCsvRowFromFile($file); $secondRow = getCsvRowFromFile($file);

In this example, we will rename a file.

use function Folded\changeName; changeName("path/to/old.txt", "path/to/new.txt");

In this example, we will write on an opened file.

use function Folded\writeOnFile; $file = fopen("path/to/file.txt"); writeToFile($file, "some text");

If you need to get the number of bytes written, get the return of the function.

use function Folded\writeOnFile; $file = fopen("path/to/file.txt"); $numberOfBytesWritten = writeToFile($file, "some text"); echo "$numberOfBytesWritten bytes written";
