PHP to Javascript Project: php.js
This article is part of the 'Porting PHP to Javascript' Project, which aims to decrease the gap between developing for PHP & Javascript.
A lot of people are familiar with PHP's functions, and though Javascript functions are often quite similar, some functions may be missing or addressed differently. The Javascript implementations should be as compliant with the PHP versions as possible, a good indication is that the PHP function manual could also apply to the Javascript version.
Porting crucial PHP functions to Javascript can be fun & useful. Currently some PHP functions have been added, but readers are encouraged to contribute and improve functions by adding comments. Eventually the goal is to save all the functions in one php.js file and make it publicly available for your coding pleasure.
If you choose to contribute, let me know how you want to be credited in the function's comments. You may also want to subscribe to RSS so you receive updates whenever new functions are posted.
This is a Javascript version of the PHP function: base64_decode.
PHP base64_decode
Description
base64_decode - Decodes data encoded with MIME base64
string base64_decode( string data [, bool strict] )
Decodes a base64 encoded data.
Parameters
-
data
The decoded data.
-
strict
Returns FALSE if input contains space or some other separator.
Return Values
Returns the original data or FALSE on failure. The returned data may be binary.

Source
This is the main source of the Javascript version of PHP's base64_decode
function base64_decode( data ) { // http://kevin.vanzonneveld.net // + original by: Tyler Akins (http://rumkin.com) // + improved by: Thunder.m // + input by: Aman Gupta // + improved by: Kevin van Zonneveld (http://kevin.vanzonneveld.net) // - depends on: utf8_decode // * example 1: base64_decode('S2V2aW4gdmFuIFpvbm5ldmVsZA=='); // * returns 1: 'Kevin van Zonneveld' // mozilla has this native // - but breaks in 2.0.0.12! //if (typeof window['btoa'] == 'function') { // return btoa(data); //} var b64 = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/="; var o1, o2, o3, h1, h2, h3, h4, bits, i = ac = 0, dec = "", tmp_arr = []; do { // unpack four hexets into three octets using index points in b64 h1 = b64.indexOf(data.charAt(i++)); h2 = b64.indexOf(data.charAt(i++)); h3 = b64.indexOf(data.charAt(i++)); h4 = b64.indexOf(data.charAt(i++)); bits = h1<<18 | h2<<12 | h3<<6 | h4; o1 = bits>>16 & 0xff; o2 = bits>>8 & 0xff; o3 = bits & 0xff; if (h3 == 64) { tmp_arr[ac++] = String.fromCharCode(o1); } else if (h4 == 64) { tmp_arr[ac++] = String.fromCharCode(o1, o2); } else { tmp_arr[ac++] = String.fromCharCode(o1, o2, o3); } } while (i < data.length); dec = tmp_arr.join(''); dec = utf8_decode(dec); return dec; }
To run the Javascript base64_decode, you will also need the following dependencies:
Examples
Currently there is 1 example
Example 1
base64_decode('S2V2aW4gdmFuIFpvbm5ldmVsZA==');And that would return

Generally the best way is to use a minified version and gzip it
Testing the functions
The number of functions is growing fast and so it becomes hard to maintain quality.
To defeat that danger of bad code, syntax errors, etc, I've added a new feature: php.js tester.
It is an automatically generated page that includes ALL functions in your browser, and then extracts specific testing information from each function's comments. This info is then used to run the function, and the return value is compared to a predefined one.
This way code is always checked on syntax errors, and if it doesn't function correctly anymore after an update, we should also be able to detect it more easily.
If you want, go check it out.

Coming Project features
Project features that we are currently working on:
- Versioning. Individual functions are versioned, but the entire library should be versioned as well.
- Light. A lightweight version of php.js should be made available with only common functions in it.

In firefox, window.atob works for decoding as long as you don't pass in a large string. Over a certain size, it fails with an 'out of memory' error.

#1. TXGruppi on 08 April 2008
Reading the functions I found the base64_encode and base64_decode in a way very complicated.
There are the functions btoa and atob in JavaScript that make this conversion.
