strcmp equivelant for integers (intcmp) in PHP

So we got this function in PHP

strcmp(string $1,string $2) // returns -1,0, or 1;

We Do not however, have an intcmp(); So i created one:

function intcmp($a,$b) {
    if((int)$a == (int)$b)return 0;
    if((int)$a  > (int)$b)return 1;
    if((int)$a  < (int)$b)return -1;
}

This just feels dirty. What do you all think?

this is part of a class to sort Javascripts by an ordering value passed in.

class JS
{
    // array('order'=>0,'path'=>'/js/somefile.js','attr'=>array());
    public $javascripts = array(); 
    ...
    public function __toString()
    {
        uasort($this->javascripts,array($this,'sortScripts'));
        return $this->render();
    }
    private function sortScripts($a,$b)
    {
        if((int)$a['order'] == (int)$b['order']) return 0;
        if((int)$a['order'] > (int)$b['order']) return 1;
        if((int)$a['order'] < (int)$b['order']) return -1;
    }
    ....
}

Solution 1:

Sort your data with:

function sortScripts($a, $b)
{
    return $a['order'] - $b['order'];
}

Use $b-$a if you want the reversed order.

If the numbers in question exceed PHP's integer range, return ($a < $b) ? -1 : (($a > $b) ? 1 : 0) is more robust.

Solution 2:

You could use

function intcmp($a,$b)
    {
    return ($a-$b) ? ($a-$b)/abs($a-$b) : 0;
    }

Although I don't see the point in using this function at all
