 1 | # PHP-Base64
 2 | 
 3 | Simple and convenient Base64 encoding and decoding for PHP
 4 | 
 5 | ## Requirements
 6 | 
 7 |  * PHP 5.3.0+
 8 | 
 9 | ## Installation
10 | 
11 |  1. Include the library via Composer [[?]](https://github.com/delight-im/Knowledge/blob/master/Composer%20(PHP).md):
12 | 
13 |     ```
14 |     $ composer require delight-im/base64
15 |     ```
16 | 
17 |  1. Include the Composer autoloader:
18 | 
19 |     ```php
20 |     require __DIR__ . '/vendor/autoload.php';
21 |     ```
22 | 
23 | ## Usage
24 | 
25 | ### Standard
26 | 
27 |  * Encoding data
28 | 
29 |    ```php
30 |    \Delight\Base64\Base64::encode('Gallia est omnis divisa in partes tres');
31 |    // string(52) "R2FsbGlhIGVzdCBvbW5pcyBkaXZpc2EgaW4gcGFydGVzIHRyZXM="
32 |    ```
33 | 
34 |  * Decoding data
35 | 
36 |    ```php
37 |    \Delight\Base64\Base64::decode('R2FsbGlhIGVzdCBvbW5pcyBkaXZpc2EgaW4gcGFydGVzIHRyZXM=');
38 |    // string(38) "Gallia est omnis divisa in partes tres"
39 |    ```
40 | 
41 | ### URL-safe
42 | 
43 |  * Encoding data
44 | 
45 |    ```php
46 |    \Delight\Base64\Base64::encodeUrlSafe('πάντα χωρεῖ καὶ οὐδὲν μένει …');
47 |    // string(80) "z4DOrM69z4TOsSDPh8-Jz4HOteG_liDOus6x4b22IM6_4b2QzrThvbLOvSDOvM6tzr3Otc65IOKApg~~"
48 |    ```
49 | 
50 |  * Decoding data
51 | 
52 |    ```php
53 |    \Delight\Base64\Base64::decodeUrlSafe('z4DOrM69z4TOsSDPh8-Jz4HOteG_liDOus6x4b22IM6_4b2QzrThvbLOvSDOvM6tzr3Otc65IOKApg~~');
54 |    // string(58) "πάντα χωρεῖ καὶ οὐδὲν μένει …"
55 |    ```
56 | 
57 | ### URL-safe without padding
58 | 
59 |  * Encoding data
60 | 
61 |    ```php
62 |    \Delight\Base64\Base64::encodeUrlSafeWithoutPadding('πάντα χωρεῖ καὶ οὐδὲν μένει …');
63 |    // string(78) "z4DOrM69z4TOsSDPh8-Jz4HOteG_liDOus6x4b22IM6_4b2QzrThvbLOvSDOvM6tzr3Otc65IOKApg"
64 |    ```
65 | 
66 |  * Decoding data
67 | 
68 |    ```php
69 |    \Delight\Base64\Base64::decodeUrlSafeWithoutPadding('z4DOrM69z4TOsSDPh8-Jz4HOteG_liDOus6x4b22IM6_4b2QzrThvbLOvSDOvM6tzr3Otc65IOKApg');
70 |    // string(58) "πάντα χωρεῖ καὶ οὐδὲν μένει …"
71 |    ```
72 | 
73 | ## Specifications
