note 118003 added to reserved.variables.get

pls i need help on how to make my code work for search engine. <?php //connect server and database here //then below is the set command and query if(isset($_GET['search'])) { $search_value= $_GET['value']; $query = "select * from sites where keywords like '%search_value'"; $my_run = mysql_query($query); while ($row = mysql_fetch_array($my_run)) { $title =$row['title']; $link =$row['link']; $desc =$row['description']; echo "<h1>$title</h1><a href= '$link'>$link</a><p>$desc</p>"; } } ?> Error : but it keeps telling me that i can make use of global array $_GET , that i should instead use filter_input. Now i set up my filter_input code like this but still did not search my database to return result . but it gave no error. please i need help. if(!empty(INPUT_GET ('search'))){ $search_value = filter_input(INPUT_GET, 'value'); $query = "select * from sites where keywords like '%search_value'"; $my_run = mysql_query($query); while ($row = mysql_fetch_array($my_run)) { $title =$row['title']; $link =$row['link']; $desc =$row['description']; echo "<h1>$title</h1><a href= '$link'>$link</a><p>$desc</p>"; } } ?> ---- Server IP: 72.52.91.14 Probable Submitter: 212.119.150.32 ---- Manual Page -- http://php.net/manual/en/reserved.variables.get.php Edit -- https://master.php.net/note/edit/118003 Del: integrated -- https://master.php.net/note/delete/118003/integrated Del: useless -- https://master.php.net/note/delete/118003/useless Del: bad code -- https://master.php.net/note/delete/118003/bad+code Del: spam -- https://master.php.net/note/delete/118003/spam Del: non-english -- https://master.php.net/note/delete/118003/non-english Del: in docs -- https://master.php.net/note/delete/118003/in+docs Del: other reasons-- https://master.php.net/note/delete/118003 Reject -- https://master.php.net/note/reject/118003 Search -- https://master.php.net/manage/user-notes.php
