note 71476 added to function.mysqli-real-escape-string

I am wondering why nobody explain how to use this command? If I will do a query which will insert in a field named title : the string <?php echo "123";?>, than it will be dangerous or not to display that with echo in a page? If I try that to output after I get it with $row["title"] sometimes is it shown, sometime is not ! So anyone please illuminate a noob path in PHP please. ---- Server IP: 66.163.161.117 Probable Submitter: 86.104.141.48 ---- Manual Page -- http://www.php.net/manual/en/function.mysqli-real-escape-string.php Edit -- https://master.php.net/note/edit/71476 Del: integrated -- https://master.php.net/note/delete/71476/integrated Del: useless -- https://master.php.net/note/delete/71476/useless Del: bad code -- https://master.php.net/note/delete/71476/bad+code Del: spam -- https://master.php.net/note/delete/71476/spam Del: non-english -- https://master.php.net/note/delete/71476/non-english Del: in docs -- https://master.php.net/note/delete/71476/in+docs Del: other reasons-- https://master.php.net/note/delete/71476 Reject -- https://master.php.net/note/reject/71476 Search -- https://master.php.net/manage/user-notes.php
