Answer 1

Check this:

$content .= '<div class="evt_date" >
             <meta itemprop="startDate" content="'.$data[$k]['startDate'].'">
             <meta itemprop="endDate" content="'.$data[$k]['endDate'].'">
             <span><button type="button" class="btn btn-primary btn-listing"  onClick="favaorite('.$data[$k]['id'].',\''.$data[$k]['city'].'\',\''.$data[$k]['country'].'\',\''.$data[$k]['event_url'].'\')">Addtofavorite</button>
             </span>';

Answer 2

Separate the multiple quotes, ie quotes within quotes.

$click_fnt = "favaorite($data[$k]['id'],$data[$k]['city'],$data[$k]['country'],$data[$k]['event_url'])";

and add it to your code

$content .= '<div class="evt_date" >
             <meta itemprop="startDate" content="'.$data[$k]['startDate'].'">
             <meta itemprop="endDate" content="'.$data[$k]['endDate'].'">
             <span><button type="button" class="btn btn-primary btn-listing"  onClick="'.$click_fnt.'">Addtofavorite</button>
             </span>';

This way it wont confuse the compiler nor the programmer.
