Using usort in php to sort an array of objects?

Question

I did look at usort, but am still a little confused...

Here is what the $myobject object looks like:

Array
(
    [0] => stdClass Object
                 


        

Answer 1

For get property stdClass Object use operator ->{'name_property'}, eg $a->{'tid'}

function cmp( $a, $b )
{ 
  if(  $a->{'tid'} ==  $b->{'tid'} ){ return 0 ; } 
  return ($a->{'tid'} < $b->{'tid'}) ? -1 : 1;
} 
usort($myobject,'cmp');

function sort_by_tid( $a, $b )
{ 
  if(  $a->{'tid'} ==  $b->{'tid'} ){ return 0 ; } 
  return ($a->{'tid'} < $b->{'tid'}) ? -1 : 1;
} 
usort($myobject,'sort_by_tid');
