This is a Javascript version of the PHP function: str_split.

PHP str_split

Description

str_split - Convert a string to an array

array str_split( string string [, int split_length] )

Converts a string to an array.

Parameters

• string

  The input string.

• split_length

  Maximum length of the chunk.

Return Values

If the optional split_length parameter is specified, the returned array will be broken down into chunks with each being split_length in length, otherwise each chunk will be one character in length.

FALSE is returned if split_length is less than 1. If the split_length length exceeds the length of string , the entire string is returned as the first (and only) array element.

    if (f_split_length == undefined) {
        f_split_length = 1;
    }
    if(f_split_length > 0){
        var result = [];
        while(f_string.length > f_split_length) {
            result[result.length] = f_string.substring(0, f_split_length);
            f_string = f_string.substring(f_split_length);
        }
        result[result.length] = f_string;

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.
