Bit&Black Base64 String

Encodes files to base64 strings and decodes base64 strings to files.

Installation

This library is made for the use with Composer. Add it to your project by running $ composer require bitandblack/base64-string.

Usage

Initialize the Base64String with the path to the file you want to encode:

<?php

use BitAndBlack\Base64String\Base64String;

$base64String = new Base64String('/path/to/myfile.txt');

You can access the single parts of the base64 string now like that:

<?php

/** Will echo something like "data:text/plain;base64,SGVsbG8gV29ybGQh..." */
echo $base64String->getBase64String();

/** Will echo "text/plain" */
echo $base64String->getMimeType();

Or simply echo the object:

<?php

/** This will also echo something like "data:text/plain;base64,SGVsbG8gV29ybGQh..." */
echo new Base64String('/path/to/myfile.txt');

Backwards

You can also convert a base64 encoded string and extract its parts:

<?php

use BitAndBlack\Base64String\Base64File;

$base64File = new Base64File('data:text/plain;base64,SGVsbG8gV29ybGQh');

You can access the single parts of the file now like that:

<?php

/** Will echo "txt" */
echo $base64File->getExtension();

/** Will echo "Hello World!" using the input string above */
echo $base64File->getContent();

/** Will echo "text/plain" */
echo $base64File->getMimeType();

With that information it is easy to write that file to the file system:

<?php

file_put_contents(
 'myfile.txt', /** Or `'myfile.' . $base64File->getExtension(),` if you prefer. */
 $base64File
);
