    ▪php自动删除mysql死连接(Sleep)的方法      本文介绍php自动删除MYSQL死连接(Sleep)的方法，供大家学习参考。   代码如下: <?php define('MAX_SLEEP_TIME', 120);   $hostname = "localhost"; $username = "root"; $password = "password";   $connect = mysql_connect().........

代码如下:

<h1>Employee listing</h1>
<form method="post" >
<p>Enter Department ID:
<input type="text" name="dept_id" size="4">
<input type="submit" name="submit" value="submit"><p>
</form>

代码如下:

<?php
$hostname = "localhost";
$username = "root";
$password = "secret";
$database = "prod";

if (IsSet ($_POST['submit'])) {

     $dbh = new mysqli($hostname, $username, $password, $database);

     /* check connection */
     if (mysqli_connect_errno()) {
          printf("Connect failed: %s\n", mysqli_connect_error());
          exit ();
     }
     $dept_id = $_POST['dept_id'];

     if ($result_set = $dbh->query("call employee_list( $dept_id )")) {
          print ('<table border="1" width="30%"> <tr> '.
               '<td>Employee_id</td><td>Surname</td><td>Firstname</td></tr>');
          while ($row = $result_set->fetch_object()) {
               printf("<tr><td>%s</td><td>%s</td><td>%s</td></tr>\n",
                      $row->employee_id, $row->surname, $row->firstname);
          }
     } else {
          printf("<p>Error:%d (%s) %s\n", mysqli_errno($dbh),
                 mysqli_sqlstate($dbh), mysqli_error($dbh));
     }
     print ("</table> ");
     $dbh->close();
}
?>

代码如下:

<?php
set_time_limit(13600);  //设置时间
$conn=mysql_connect()('localhost','root',''); //连接数据库
mysql_select_db('csdn',$conn);
mysql_query()("SET NAMES utf8");
$file=file('csdn.txt');

foreach($file as $line)
{
    $u=explode()('# ', $line);
    mysql_query("INSERT INTO `user` (username,password,email)VALUES('".trim($u[0])."','".trim($u[1])."','".trim($u[2])."')",$conn);
}
echo 'OK';
?>

代码如下:

<?php
define('MAX_SLEEP_TIME', 120);
 
$hostname = "localhost";
$username = "root";
$password = "password";
 
$connect = mysql_connect()($hostname, $username, $password);
$result = mysql_query()("SHOW PROCESSLIST", $connect);
while ($proc = mysql_fetch_assoc($result)) {
    if ($proc["Command"] == "Sleep" && $proc["Time"] > MAX_SLEEP_TIME) {
        @mysql_query("KILL " . $proc["Id"], $connect);
    }
}
mysql_close($connect);
?>

代码如下:
