我只需要一个从 php-Script 调用的简单 mysqli-Connection。以下脚本没有响应。如果出现某种错误消息，甚至是一些用于调试目的的回声语句，会更容易。但不是。只有白屏。
<?php
private $db_config_file = realpath(dirname(__FILE__)) . "config/db.ini";
private $db = NULL;
if (!file_exists($this->db_config_file)) {
$msg = "The config-file <code>"
. $this->db_config_file
. "</code> doesnt't exist.";
show_error_page($msg);
}
$config = parse_ini_file($this->db_config_file);
$host = $config[$host];
$user = $config[$user];
$password = $config[$password];
$dbname = $config[$dbname];
$conn = new mysqli($host, $user, $password, $dbname);
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
} else echo "Connection established!";
$conn->close();
?>
db.ini：
host = localhost
dbname = bl
user = mm
password = noadmin
尝试改变
$host = $config[$host];
$user = $config[$user];
$password = $config[$password];
$dbname = $config[$dbname];
至
$host = $config['host'];
$user = $config['user'];
$password = $config['password'];
$dbname = $config['dbname'];
你正在使用 $host = $config[$host]，它需要是 $config['host']
