PHP to Javascript Project: php.js

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: base_convert.

PHP base_convert

Description

base_convert - Convert a number between arbitrary bases

string base_convert ( string number, int frombase, int tobase)

numberThe number to convert

Parameters

number
The number to convert
frombase
The base number is in
tobase
The base to convert number to

Return Values

number converted to base tobase

Javascript base_convert

Source

This is the main source of the Javascript version of PHP's base_convert

function base_convert(number, frombase, tobase) {
    // http://kevin.vanzonneveld.net
    // +   original by: Philippe Baumann
    // *     example 1: base_convert('A37334', 16, 2);
    // *     returns 1: '101000110111001100110100'
 
    return parseInt(number+'', frombase+0).toString(tobase+0);
}

Examples

Currently there is 1 example

Example 1

This is how you could call base_convert()

base_convert('A37334', 16, 2);

And that would return

'101000110111001100110100'

Coming Project features

Project features that we are currently working on:

Site. A place for php.js of it's own. You can track our lame attempts at phpjs.org. If there are any CakePHP developers out there who would like to help out, please contact me.
Compile. Compile your own php.js version, with only the functions you need. Should generate a hash with which you can retrieve latest versions of your php.js combination.
docBlock. Move to docBlock comments for improved compatibility with IDEs.
Done - Testsuite. A better test-suite that can be ran locally so developers can easily test before commiting. Also the testing itself should be more thorough.
Done - Versioning. Individual functions are versioned, but the entire library should be versioned as well.
