Answer 1

Verwenden isset() zu überprüfen, ob eine Variable vorhanden oder nicht, Sie Code wie sein sollten,

print isset($img_array[3]) && '<div style="position:absolute; left:15.5%; top:125%;"> 
     <img src="../../fb_users/'.$gender.'/'.$user.'/Post/'.$img_array[3].'" 
     height="90" width="78"></div>'; 

Verwenden gleicher Code für anderen Array-Indizes.
