今天本能是想测试一个PDO持久化，会不会带来会话混乱的问题 先贴一下PHP代码, 代码丑了点，但是坚持能run就行，反正就是做个测试。
<?php
$dsn = 'mysql:host=localhost;dbname=test;charset=utf8';
$user = 'root';
$password = 'root';
// 设置 PDO 选项，启用持久化连接
$options = [
PDO::ATTR_PERSISTENT => true,
PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION
];
try {
// 创建持久化连接
$pdo = new PDO($dsn, $user, $password, $options);
$stmt = $pdo->prepare("INSERT INTO test_last_insert_id (uni) VALUES (:uni);");
$uni = uniqid('', true);
$stmt->bindValue(':uni', $uni);
$aff = $stmt->execute(); //
if ($aff === false) {
throw new Exception("insert fail:");
}
$id = $pdo->lastInsertId();
function getExecutedSql($stmt, $params)
{
$sql = $stmt->queryString;
$keys = array();
$values = array();
// 替换命名占位符 :key with ?
$sql = preg_replace('/\:(\w+)/', '?', $sql);
// 绑定的参数可能包括命名占位符，我们需要将它们转换为匿名占位符
foreach ($params as $key => $value) {
$keys[] = '/\?/';
$values[] = is_string($value) ? "'$value'" : $value;
}
// 替换占位符为实际参数
$sql = preg_replace($keys, $values, $sql, 1, $count);
return $sql;
}
$stmt = $pdo->query("SELECT id FROM test_last_insert_id WHERE uni = '{$uni}'", PDO::FETCH_NUM);
$row = $stmt->fetch();
$value = $row[0];
if ($value != $id) {
throw new Exception("id is diff");
}
echo "success" . PHP_EOL;
} catch (PDOException $e) {
header('HTTP/1.1 500 Internal Server Error');
file_put_contents('pdo_perisistent.log', $e->getMessage() . PHP_EOL);
die('Database connection failed: ' . $e->getMessage());
} catch (Exception $e) {
header('HTTP/1.1 500 Internal Server Error');
file_put_contents('pdo_perisistent.log', $e->getMessage() . PHP_EOL);
die('Exception: ' . $e->getMessage());
}
