The table img is the stored picture path, that is, the path under the WWW directory, since the table is stored in the path, then we can use the PHP link database to obtain:

<?PHPrequire"DBDA.class.php";//calling the encapsulation class    $db=NewDbda (); $sql= "SELECT * FROM book"; $arr=$db->query ($sql); foreach($arr  as $v)//iterate through the contents of each column    {        //The image gets the path with an IMG tag, because the traversal of the IMG is $v[5], so the path is $v[5]        Echo"<div id= ' Hang ' ><a href= ' gouwu.php?bkid={$v[0]} ' >$v[5]} ' ></a> <div class= ' JG ' ><a href= ' gouwu.php?bkid={$v[0]} ' >{$v[1]}</a></div> <div class= ' JG ' style= ' color:red ' >{$v[3]} meta </div> </div>"; }?>
