PHP to Javascript Project: php.js

php.jsThis 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: md5.

I have moved out PHP.JS to it's own site. For info & reactions on comments please goto phpjs.org

PHP md5

Description

md5 - Calculate the md5 hash of a string

string md5( string str [, bool raw_output] )

Calculates the MD5 hash of str using the » RSA Data Security, Inc. MD5 Message-Digest Algorithm, and returns that hash.

Parameters

  • str

    The string.

  • raw_output

    If the optional raw_output is set to TRUE, then the md5 digest is instead returned in raw binary format with a length of 16. Defaults to FALSE.

Return Values

Returns the hash as a 32-character hexadecimal number.

To run the Javascript md5, you will also need the following dependencies:

Examples

Currently there is 1 example

Example 1

This is how you could call md5()
md5('Kevin van Zonneveld');
And that would return
'6e658d4bfcb59cc13f96c14450ac40b9'

Coming Project features

Project features that we are currently working on:

  • Done - Site. A place for php.js of it's own. See: phpjs.org.
  • Done - 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.
    • 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.

#5. Philip Andrew on 30 January 2008

Default avatar:Philip AndrewThis is a good idea if you want to combine it with Aptana JAXER then it makes JAXER more like PHP.

#4. Kevin on 29 January 2008

Member avatar: Kevin@ Eric: Interesting thought.
But that would mean maintaining multiple versions of the same function, just to be able to do a 'solid' benchmark (by eliminating as many variables such as platform, browser, processor, etc. between your workstation and mine).

And storing and maintaining different versions for the sole purpose of a micro benchmark would slow the project down in this phase, I think.

... [more] So for now, I think I'll leave it up to the community to suggest speed improvements instead.

But thanks for your input, very much appreciated!

#3. Eric on 28 January 2008

Default avatar:EricI think it'd be fantastic to see these functions coupled with some performance measurements, both so we can see areas need optimization and to help people understand which operations are unrealistically expensive.

#1. Ates Goral on 18 January 2008

Default avatar:Ates GoralA while back, I had published a function called phpSerialize() (that does what the PHP serialize() function does) at http://magnetiq.com/2006/07/30/php-style-serialization-of-javascript-objects/

Here's the code copied here: 

/* Returns the class name of the argument or undefined if
   it's not a valid JavaScript object.
*/
function getObjectClass(obj)
{
    if (obj && obj.constructor && obj.constructor.toString)
    {
        var arr = obj.constructor.toString().match(
            /function\s*(\w+)/);
 
        if (arr && arr.length == 2)
        {
            return arr[1];
        }
    }
 
    return undefined;
}
 
/* Serializes the given argument, PHP-style.
 
   The type mapping is as follows:
 
   JavaScript Type    PHP Type
   ---------------    --------
   Number             Integer or Decimal
   String             String
   Boolean            Boolean
   Array              Array
   Object             Object
   undefined          Null
 
   The special JavaScript object null also becomes PHP Null.
   This function may not handle associative arrays or array
   objects with additional properties well.

function phpSerialize(val)
{
    switch (typeof(val))
    {
    case "number":
        return (Math.floor(val) == val ? "i" : "d") + ":" +
            val + ";";
