Just a simple implementation for JavaScript:
<?php
function array_unique(thearray)
{
thearray.sort();
//reset($thearray);
newarray = new Array();
for (n=0;n<thearray.length;n++)
{
unique=1;//by default
for(nn=0;nn<newarray.length;nn++)
if (thearray[n] == newarray[nn])
{
unique=0;//already exists
break;
}
if(unique)//dont exists
newarray.push(thearray[n]);
}
return newarray;
}
?>
