Downside of all answers here is that they use static field names, so I wrote an adjusted version in OOP style. Assumed you are using getter methods you could directly use this Class and use the field name as parameter. Probably someone find it useful.

class CustomSort{

    public $field = '';

    public function cmp($a, $b)
    {
        /**
         * field for order is in a class variable $field
         * using getter function with naming convention getVariable() we set first letter to uppercase
         * we use variable variable names - $a->{'varName'} would directly access a field
         */
        return strcmp($a->{'get'.ucfirst($this->field)}(), $b->{'get'.ucfirst($this->field)}());
    }

    public function sortObjectArrayByField($array, $field)
    {
        $this->field = $field;
        usort($array, array("Your\Namespace\CustomSort", "cmp"));;
        return $array;
    }
}
