» Javascript equivalent for PHP's array

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: array.

PHP array

Description

Javascript array

Source

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

function array( ) {
    // http://kevin.vanzonneveld.net
    // +   original by: d3x
    // *     example 1: array('Kevin', 'van', 'Zonneveld');
    // *     returns 1: ['Kevin', 'van', 'Zonneveld']
 
    return Array.prototype.slice.call(arguments);
}

Examples

Currently there is 1 example

Example 1

This is how you could call array()
array('Kevin', 'van', 'Zonneveld');
And that would return
['Kevin', 'van', 'Zonneveld']

To easily include it in your code, every function currently available is stored in

Namespaced What is 'namespaced?'

To download use Right click, Save Link As
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.

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.
  • Site. A place for PHP.JS of it's own. You can track our lame attempts at phpjs.org (not hyperlinked deliberately). If there are any CakePHP developers out there who would like to contribute, contact me.
  • 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.

Member avatar: Kevin@ thinsoldier: What about them? Judging by your comment I would think you mean that our asort doesn't support them.. But it appears we don't have an asort yet ;)
JavaScript does support them in general. But they're called objects to be strict.
But I guess I don't fully understand your question.

#1. thinsoldier on 19 June 2008

Default avatar:thinsoldierwhat about associative arrays?
var Divs = array(); // array of divs that I want to sort
Divs['amelie'] = divHtmlElement3;
Divs['randolph'] = divHtmlElement1;
Divs['judy'] = divHtmlElement9;
... [more]
asort(Divs);

showDivArray(Divs);
