Sorting objects by their property..

Prepare some sample objects:

$to_be_sorted = array();
$chars = 'abcdefg';
for($i = 0;$i< 3;$i++ ){
  $random_number = rand(1,99);
  $to_be_sorted[] = (object) [
    'num' => $random_number,
    'str' => $chars[$random_number % 7]
  ];
}

Sort by number

usort($to_be_sorted,function($a,$b){
  return $a -> num > $b -> num;
}); 

Use usort PHP function.

Sort by string

usort($to_be_sorted,function($a,$b){
  return (int)strcmp($a -> str,$b -> str);
});
