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: number_format.

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

PHP number_format

Description

number_format - Format a number with grouped thousands

string number_format ( float number[, int decimals[, string dec_point]], string thousands_sep)

number_format() returns a formatted version of number.This function accepts either one, two or four parameters (not three):

Examples

Currently there are 6 examples

Example 1

This is how you could call number_format()
number_format(1234.56);
And that would return
'1,235'

Example 2

This is how you could call number_format()
number_format(1234.56, 2, ',', ' ');
And that would return
'1 234,56'

Example 3

This is how you could call number_format()
number_format(1234.5678, 2, '.', '');
And that would return
'1234.57'

Contributing is as easy as adding a comment with better code, or code for a new function.
Any contribution leading to improvement will directly get your name & link here.


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.

#25. Rival on 12 February 2009

Gravatar.com: Rival- show thousand separator for number=1000

note: for 1000.55 result with precision 1 in FF/Opera is 1,000.5, but in IE is 1,000.6

#22. Diogo Resende on 02 February 2009

Gravatar.com: Diogo ResendeIt's not correct for numbers below 1000. It needs an else statement like this:

if (abs > 1000) {
...
} else {
s = abs.replace('.', ',');
}

Member avatar: Kevin@ Luke: After I changed:

prec = !isFinite(+prec) ? 2 : Math.abs(prec);


To

prec = !isFinite(+prec) ? 0 : Math.abs(prec);


..All test cases from the php manual worked perfectly. And since your code is a bit easier on the eyes as well, I'll include it in our project. Thanks a lot!

http://gist.github.com/47871

more lines, but fewer characters, and compresses (via YUI Compressor) to about 83% of the version above. Take a look; there may be improvements to be made.

Gravatar.com: MariuszI take it back, got the latest version and all looks good. Thanks to those involved with the fixes!

#16. Mariusz on 04 November 2008

Gravatar.com: MariuszThis method does not seem to work correctly with negative numbers, for example (to 2 decimal places):

-16038 returns: -160,38.00

-820 returns -,820.00

Gravatar.com: Chad SmithIgnore my previous comment, I'm an idiot. I was checking to see if it was larger than 1000 before it ran through the function. Duh, sorry.

Love the script!
Chad

#14. Chad Smith on 28 August 2008

Gravatar.com: Chad SmithAnyone else notice that if you just put in 1000 it doesn't format the number to 1,000? But if you put in 1001 it formats correctly to 1,001.

Any idea what could make that happen?

#13. Kevin on 08 June 2008

Member avatar: Kevin@ Howard Yeend: Thanks for noticing. This function was revised, and that reimported a previously fixed bug. It's probably because in some countries (including my own), the dec_point and thou_sep are indeed the other way around compared to the english standard. Anyway. fixed again :)

#12. Howard Yeend on 06 June 2008

Default avatar:Howard Yeendjust a comment; aren't the default values for dec_point and thou_sep the wrong way around?

by default it formats 12345.67 as 12.345,67

shouldn't it be 12,345.67 ?

#11. Kevin on 13 April 2008

Member avatar: Kevin@ Jonas Raoni: Thanks I've updated the function. I have one remark though. We generally compress code with packer & jsmin to obtain bandwidth & speed advantages, while maintaining readability so developers can more easily understand and update each others code.

#10. Jonas Raoni on 12 April 2008

Default avatar:Jonas RaoniI corrected all of the bugs that I found:
- Negative numbers;
- Starting with zero;
- Rouding (when cutting the decimal places of "0.9" it should be 1 not 0).

... [more] And here is the last version of the code:

Number.prototype.formatMoney = function(c, d, t){
var n = this, c = isNaN(c = Math.abs(c)) ? 2 : c, d = d == undefined ? "," : d, t = t == undefined ? "." : t, s = n < 0 ? "-" : "",
i = parseInt(n = Math.abs(+n || 0).toFixed(c)) + "", j = (j = i.length) > 3 ? j % 3 : 0;
return s + (j ? i.substr(0, j) + t : "") + i.substr(j).replace(/(\d{3})(?=\d)/g, "$1" + t)
+ (c ? d + Math.abs(n - i).toFixed(c).slice(2) : "");
};

Default avatar:Allan JensenFixed the problem with negative numbers myself. Function needs to look like this:

return neg + km + kw + kd;
}

#6. Allan Jensen on 28 March 2008

Default avatar:Allan JensenThe function has a problem with negative numbers.

This:

number_format(-258.75, 2, ",", ".")
... [more]
incorrectly gives:

-,258,75

Please help me fix this.

#4. Benjamin &quot;balupton&quot; Lupton on 20 March 2008

Default avatar:Benjamin \"balupton\" Luptondec_point and thousands_sep defaults should be the other way round

#3. Michael White on 01 March 2008

Default avatar:Michael WhiteNo problem. I love having these familiar PHP functions available. I have a sort of proposal for you, maybe you could contact me via email (michael -a-t- crestidg.com) so I can get you some more details. It probably wouldn't take too much time for us to do and it would benefit those who want to use the entire PHP.js package along side other JavaScript quite a lot.

#2. Kevin on 01 March 2008

Member avatar: Kevin@ Michael White: It sure did, thanks for taking the time to supply better code. I've updated the function!

#1. Michael White on 01 March 2008

Default avatar:Michael WhiteThere is a bug in Safari - at least in Safari 3.0.4 that causes the combination of Math.abs(0).toFixed(x) where x seems to be any positive integer to provide erroneous output.

The sample code below contains problematic code at the top and a sample solution line at the end. The new code for the number_format() function actually is in a separate code block below this one.

var price = 0.00;
alert(Math.abs(price)); // Alerts: 0 - correct.

// Alerts: 0.00 in most browsers.
// In Safari 3.0.4 you get: 0.-0
alert(Math.abs(price).toFixed(2));

// However - If you skip the use of Math.abs() on a 0 value then the toFixed() function works correctly.
var new_price = 0;
alert(new_price.toFixed(2));

// Temp-fix ( I submitted this bug to Apple)
var num = 0;
var result = Math.abs(0).toFixed(1);
alert(result);
result = result.replace(/-/, 0);
alert(result);


Since this problem only occurs when working on a value of 0 (zero) to begin with we know that the hyphen character should be a 0 so we can simply replace it with a 0 if it is found.

// The easiest way to fix this is to simply modify the line that reads:
kd = (decimals ? dec_point + Math.abs(number - i).toFixed(decimals).slice(2) : "");
 
// with the following line of code:
kd = (decimals ? dec_point + Math.abs(number - i).toFixed(decimals).replace(/-/, 0).slice(2) : "");
 
// The only difference is the addition of .replace(/-/, 0) just before the slice() method is used.
// This tiny extra amount of processing should not be significant unless number_format() is run in very tight loops - and even then it can only be considered extra in browsers like IE, Opera, and Firefox since this appears to be a Safari only bug. Checking the browser seemed to be overkill in this instance.


I hope it helps!
