Fix for PHP Warning Trying to get property '*name*' of non-object

i was getting this error when checking parts of an object that were sometimes set and sometimes they did not exist depending on the values. 

Warning / Error : Warning Trying to get property '*name*' of non-object

Or: Warning Trying to get property of non-object

You can get rid of this warning quite easily with isset.

So even though it can be quite a bit more code to do it this way it checks if the property is set before trying to grab it, and then you can just assign whatever it was going to be assigned to to blank. You can see it in the following example. 

PHP

// code that was causing the warning
$imp_search_review_summary = $item->find('.search_review_summary',0)->attr['data-tooltip-html']; // attr data-tooltip-html

// code that fixes the warning
if(isset($item->find('.search_review_summary',0)->attr['data-tooltip-html'])) {
  $imp_search_review_summary = $item->find('.search_review_summary',0)->attr['data-tooltip-html']; // attr data-tooltip-html
} else {
  $imp_search_review_summary = "";
}
