$mysql_server_name="localhost"; /pic/pic/pic/pic/pic/pic/div>
/pic/div>
$result=mysql_db_query($mysql_database, $strsql, $conn);/pic/div>
echo '<table border="1" cellpadding="1" cellspacing="2">';/pic/div>
mysql_field_name($result, $i);
echo "</b></td>\n";
}
echo "</tr>\n";
/pic/div>
mysql_data_seek($result, 0);
/pic/div>
while ($row=mysql_fetch_row($result))
{
echo "<tr>\n";
for ($i=0; $i<mysql_num_fields($result); $i++ ){echo '<td bgcolor="#00FF00">';echo "$row[$i]";
echo '</td>';
}
echo "</tr>\n";

<?php$link = mysql_connect("mysql_host", "mysql_user", "mysql_password") or die("Could not connect");print "Connected successfully";mysql_select_db("my_database") or die("Could not select database");$query = "SELECT * FROM my_table";$result = mysql_query($query) or die("Query failed");print "<table>\n";while ($line = mysql_fetch_array($result, MYSQL_ASSOC)) { print "\t<tr>\n"; foreach ($line as $col_value) { print "\t\t<td>$col_value</td>\n"; } print "\t</tr>\n"; } print "</table>\n";mysql_free_result($result);mysql_close($link);?>

代码单独存为一个文件conn.php,在以后要用到这些代码时只要include这个页面就可以了.如add.php这个页面要要添加数据入数据库,那么在add.php里include "conn.php";
