我有
<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);
require_once "configuration.php";
header('Content-Type: application/json');
try
{
$mysqli = new mysqli(MYSQL_SERVER, MYSQL_USERNAME, MYSQL_PASSWORD, MYSQL_DATABASE);
$mysqli->set_charset("utf8");
} catch (Exception $e) {
echo json_encode(
array(
'msg' => $e->getMessage()
)
);
}
如果 mysqli
未启用,则它不会捕获错误:
Fatal error: Uncaught Error: Class 'mysqli' not found in C:\test\db_connect.php:8
Stack trace:
#0 C:\test\getContacts.php(2): require_once()
#1 {main} thrown in C:\test\db_connect.php on line 8
我该怎么做才能捕获错误?
这个我试过了,但是没用:
<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);
require_once "configuration.php";
header('Content-Type: application/json');
try
{
if(!extension_loaded('mysqli'))
{
throw new Exception('mysqli is not enabled');
}
$mysqli = new mysqli(MYSQL_SERVER, MYSQL_USERNAME, MYSQL_PASSWORD, MYSQL_DATABASE);
$mysqli->set_charset("utf8");
} catch (Exception $e) {
echo json_encode(
array(
'msg' => $e->getMessage()
)
);
}
这个并没有停顿,继续执行脚本。
{"msg":"mysqli is not enabled"}
Notice: Undefined variable: mysqli in C:\test\getContacts.php on line 99
Fatal error: Uncaught Error: Call to a member function query() on null in C:\test\getContacts.php:99 Stack trace: #0 {main} thrown in C:\test\getContacts.php on line 99
最佳答案
奇怪的是它不会被安装,但如果你自己安装,我想它可以被省略。我会检查程序函数是否存在
if(!function_exists('mysqli_connect')) {
throw new Exception('mysqli is not enabled');
}
关于如果未启用 mysqli,PHP 不会抛出异常,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/38838079/
