Dependencies
No dependencies, you can use this function standalone.
Open syntax issues
php.js uses JsLint to help us keep our code consistent and prevent some common bugs.
Eventually we want all code to pass or at least take into consideration most fixes suggested by JsLint, following this JsLint configuration we’ve decided on.

Here's array_count_values():
[CODE="Javascript"]
function array_count_values(array) {
// * example 1: array_count_values([ 3, 5, 3, "foo", "bar", "foo" ]);
// * returns 1: {3:2, 5:1, "foo":2, "bar":1}
// * example 2: array_count_values({ p1: 3, p2: 5, p3: 3, p4: "foo", p5: "bar", p6: "foo" });
// * returns 2: {3:2, 5:1, "foo":2, "bar":1}
// * example 3: array_count_values([ true, 4.2, 42, "fubar" ]);
// * returns 3: {42:1, "fubar":1}
function countValue(value) {
switch (typeof(value)) {
case "number":
if (Math.floor(value) != value) {
return;
}
case "string":
if (value in this) {
++this[value];
} else {
this[value] = 1;
}
}
}
var ret = new Object();
if (array instanceof Array) {
array.forEach(countValue, ret);
} else if (array instanceof Object) {
for (var key in array) {
countValue.call(ret, array[key]);
}
}
return ret;
}
