Php 为什么连接PDO中存在语法错误？

config.ini

[database]
host = 127.0.0.1
dbname = login
user = root
password = 

$con = parse_ini_file('config.ini.php');
date_default_timezone_set('Asia/Kolkata');

try {
$db = new PDO("mysql:host=$con['host'];dbname=$con['dbname']",$con['user'],$con['password']) ;
$db->setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_EXCEPTION);
} catch(PDOExpection $e ) {
die($e->getMessage());
}

PHP

dbname = login
user = root
password = 

$con = parse_ini_file('config.ini.php');
date_default_timezone_set('Asia/Kolkata');

try {
$db = new PDO("mysql:host=$con['host'];dbname=$con['dbname']",$con['user'],$con['password']) ;
$db->setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_EXCEPTION);
} catch(PDOExpection $e ) {
die($e->getMessage());
}

当我尝试连接时，会出现如下语法错误

语法错误，意外的“”（T\u封装了\u和\u空白），应为 标识符（T_字符串）或变量（T_变量）或数字 （T_NUM_字符串）

您正在使用插值在PDO

DSN

参数中包含数组表达式。因此，必须在字符串中使用

{}

花括号

$db = new PDO("mysql:host={$con['host']};dbname={$con['dbname']}", $con['user'], $con['password']) ;

或者只是简单地使用串联

$db = new PDO("mysql:host=" . $con['host'] . ";dbname=" . $con['dbname'], $con['user'], $con['password']) ;
