The raw seems to be different than the site's copy, and in the raw copy there's a cs variable that's unaccounted for.

@jd: Yes, in this function, I see no reason we shouldn't return a genuine array, since PHP is not preserving keys of an original array here but is just starting fresh (and is only producing a sequential numeric array). I've fixed in Git. Some of our other functions, however, our constrained to return an object in order to preserve keys and/or to avoid returning confusing arrays which have &quot;undefined&quot; interspersed throughout.

Shouldn't line 11 be:

var tmp_arr = []
(i.e. not curly brackets)

@JeromeM: Can you provide some sample data where it is not working? Are you using the latest version? (see &quot;raw js source&quot; link on this page) What errors? The example is working for me

Hello Mickael,

This should definitely be working in Firefox, as that is what i use to test it. Can you please give example code which causes the problem for you? Are you using any other libraries with your code like Prototype?

Hi,
I test this function with Mozilla Firefox 3.5.7 but it does not work.
I think that Mozilla has a bug concerning &quot;for in&quot; syntax.

Thanks for all scripts, PHP.JS is a very good work :)

Hmmm. I should change that to:

<pre><code>
const CASE_LOWER = 0;
const CASE_UPPER = 1;
</code></pre>

Hey Kevin, here's my implementation for array_change_key_case().

<pre><code>
var CASE_LOWER = 0;
var CASE_UPPER = 1;

function array_change_key_case(array) {
    // *     example 1: array_change_key_case(42);
    // *     returns 1: false
    // *     example 2: array_change_key_case([ 3, 5 ]);
    // *     returns 2: {0: 3, 1: 5}
    // *     example 3: array_change_key_case({ FuBaR: 42 });
    // *     returns 3: {&amp;quot;fubar&amp;quot;: 42}
    // *     example 4: array_change_key_case({ FuBaR: 42 }, CASE_LOWER);
    // *     returns 4: {&amp;quot;fubar&amp;quot;: 42}
    // *     example 5: array_change_key_case({ FuBaR: 42 }, CASE_UPPER);
    // *     returns 5: {&amp;quot;FUBAR&amp;quot;: 42}
    // *     example 6: array_change_key_case({ FuBaR: 42 }, 2);
    // *     returns 6: {&amp;quot;FUBAR&amp;quot;: 42}
    
    if (array instanceof Array) {
        return array;
    }
    
    if (array instanceof Object) {
        var case_fn = (arguments.length == 1 || arguments[1] == CASE_LOWER) ?
                &amp;quot;toLowerCase&amp;quot; : &amp;quot;toUpperCase&amp;quot;;
        var ret = new Object();
        
        for (var key in array) {
            ret[key[case_fn]()] = array[key];    
        }
        
        return ret;
    }
    
    return false;
}
</code></pre>
