PHP mysqli_thread_id() 函数
示例 - 面向对象的样式
返回当前连接的线程 ID，然后杀死连接：
<?php
$mysqli = new mysqli("localhost","my_user","my_password","my_db");
if ($mysqli -> connect_errno) {
echo "Failed to connect to MySQL: " . $mysqli -> connect_error;
exit();
}
// Get thread id
$thread_id = $mysqli -> thread_id;
// Kill connection
$mysqli -> kill($thread_id);
?>
$mysqli = new mysqli("localhost","my_user","my_password","my_db");
if ($mysqli -> connect_errno) {
echo "Failed to connect to MySQL: " . $mysqli -> connect_error;
exit();
}
// Get thread id
$thread_id = $mysqli -> thread_id;
// Kill connection
$mysqli -> kill($thread_id);
?>
查看底部的程序样式示例。
定义和用法
thread_id() / mysqli_thread_id() 函数返回当前连接的线程 ID，然后使用 mysqli_kill() 函数杀死该连接。
注释：如果连接被损坏且重新连接，线程 ID 将会改变。因此，仅当您需要的时候才获取线程 ID。
语法
面向对象的风格：
$mysqli -> thread_id()
程序风格：
mysqli_thread_id(connection)
