the problem with those functions based on the array length is that they
couldn't work with an associative array such as:
var test:Array = new Array()
test['foo'] = 1;

Also found this @ layer51.com/proto:

except using a while loop, this returns the position if found and -1 if
not.. might be little handsomer sometimes.
Array.prototype.in_array=function(value){
var l;
l = this.length;
while(l--)
{
if(this[l] == value){
return l;
}
}
return -1;
}
Of course you could rewrite the above to make them AS2. There are tons of
Array prototypes to be found there. (www.layer51.com/proto)

Hello Flashcoders,
Sometimes I'd like to use advanced array functions like those in,
say, PHP: in_array (check array for having a value),
array_unique (delete duplicates) etc.
For now, I use my own ones. Example:
function my_in_array(needle:String, haystack:Array):Boolean{
if(haystack.toString().indexOf(needle) == -1){
return true;
}else{
return false;
}
}
Frankly, I'm not sure if this is the best/fastest way for such
tasks: "needle" needs to be a string type.
Does anyone have info or ideas on this?
