Swoole\Coroutine\MySQL::recv()
接收MySQL Server的响应结果
函数名称：Swoole\Coroutine\MySQL::recv()
函数描述：该函数用于接收MySQL Server的响应结果。
适用版本：Swoole-4.4.0 及以上版本
用法：
创建Swoole\Coroutine\MySQL对象：
$mysql = new Swoole\Coroutine\MySQL();
连接MySQL Server：
$serverInfo = [
'host' => '127.0.0.1',
'port' => 3306,
'user' => 'root',
'password' => 'password',
'database' => 'test',
];
$connected = $mysql->connect($serverInfo);
if (!$connected) {
echo "MySQL连接失败：" . $mysql->connect_error . PHP_EOL;
return;
}
执行SQL查询语句：
$sql = 'SELECT * FROM `users` WHERE `id` = 1';
$queryResult = $mysql->query($sql);
if ($queryResult === false) {
echo "查询失败：" . $mysql->error . PHP_EOL;
return;
}
接收MySQL Server的响应结果：
$response = $mysql->recv();
if ($response === false) {
echo "接收响应失败：" . $mysql->error . PHP_EOL;
return;
}
示例：
<?php
$mysql = new Swoole\Coroutine\MySQL();
$serverInfo = [
'host' => '127.0.0.1',
'port' => 3306,
'user' => 'root',
'password' => 'password',
'database' => 'test',
];
$connected = $mysql->connect($serverInfo);
if (!$connected) {
echo "MySQL连接失败：" . $mysql->connect_error . PHP_EOL;
return;
}
$sql = 'SELECT * FROM `users` WHERE `id` = 1';
$queryResult = $mysql->query($sql);
if ($queryResult === false) {
echo "查询失败：" . $mysql->error . PHP_EOL;
return;
}
$response = $mysql->recv();
if ($response === false) {
echo "接收响应失败：" . $mysql->error . PHP_EOL;
return;
}
print_r($response);
以上示例展示了如何使用Swoole\Coroutine\MySQL::recv()函数来接收MySQL Server的响应结果。首先创建MySQL对象并连接到MySQL Server，然后执行SQL查询语句，并最后通过recv()函数接收响应结果。如果成功接收到响应，则打印输出结果。
