Sort an object array by a property

There are a bunch of topics on this but none of them are exactly what I need. I have an array with fname, lname, etc. I need to sort by lname using this code:

if ($myvar)
    foreach( $myvar as $key => $row) {
        echo "<p>$row->fname $row->lname";
        echo "$row->intro</p>";
        sort($row->lname);
    }
else 
    echo "<p>No Results for your search.</p>";

You can see I threw in a sort, I've also tried ksort(), but nothing is happening. I tried a couple of other things from this forum, but no luck. Is the order wrong? Is the syntax incorrect?

In your code seems like you have an array of arrays. If you have only one array, you dont need use sort inside the foreach. Sort - Sort an array, so use it directly like this:

if ($myvar) {
   uasort($myvar, function($a,$b) {return strcmp($a->lname, $b->lname);}));
}else{
    echo "<p>No Results for your search.</p>";
}

usort($myvar, function($a,$b) {return strcmp($a->lname, $b->lname);});

Though, as said in the comments, if this is searching over a database or search engine, you're better off letting those sort your stuff.
