Just an quick example how to search and add information to MySQL.

<?php 

// search.sql : https://pastee.org/e7zke
// when searching, use % as wildcard.

$con = mysql_connect("localhost","user","pw");
mysql_select_db("search", $con);

if (!$con) { die('Could not connect: ' . mysql_error()); }

if( !isset($_GET['addnew']) ) { echo "ADD NEW: <form action=# method=get><b>URL</b>: <input type=hidden name=addnew><input type=text name=u> - <b>Title</b>: <input type=text name=t> - <b>Keywords</b>: <input type=text name=kw> <input type=submit value=Add!></form><br/><br/>SEARCH: <form action=# method=get><b>Search</b>: <input type=text name=s> <input type=submit value=Search!></form>"; }

if( isset($_GET['addnew']) )  {
    $url = $_GET['u'];
    $title = $_GET['t'];
    $keywords = $_GET['kw'];
    $result = mysql_query("INSERT INTO search(title, url, word) VALUES('$title', '$url', '$keywords')");
    mysql_close($con);
    die("Added.");
}

$getme = "%";
$getme = $_GET['s'];

$result = mysql_query("SELECT SQL_CACHE * FROM search where word like '%$getme%' limit 0,25");

echo "<table border='0' padding='10'><tr><th>ID</th><th>Title</th><th width='100'>URL</th></tr>";

while($row = mysql_fetch_array($result))  {

    echo "<tr>";
    echo "<td>" . $row['id'] . "</td>";
    echo "<td>" . $row['title'] . "</td>";
    echo "<td>" . $row['url'] . "</td>";
    echo "</tr>";

}

echo "</table>";

mysql_close($con);

?>
