Question

当我在我的php文件中添加mysqli_connect语句时，它会停止处理整个脚本。如果使这个语句注释我的PHP文件按预期工作。我将此文件添加到wordpress网站。

我也尝试使用mysql_connect（）进行连接，但结果是一样的。

我的代码：

<?php

require_once ($_SERVER['DOCUMENT_ROOT'].'/wp-config.php');

ini_set('display_errors', 1); 
error_reporting(E_ALL);

//phpinfo();

echo DB_NAME ."<br>";
echo DB_USER ."<br>";
echo DB_PASSWORD ."<br>";
echo DB_HOST."<br>"


$conn = mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD,DB_NAME);
// database port is also 3306 which is default

if (!$conn) {
    echo  "Connection failed: " . mysqli_connect_error();
}
echo "Connected successfully";

?>

php.info()已安装mysqli的输出也已启用。

我是否需要包含一些文件来访问mysqli_connect()功能。

如何连接数据库？

Answer 1

你错过了 echo DB_HOST的分号。＆＃34;

    require_once ($_SERVER['DOCUMENT_ROOT'].'/wp-config.php');

    ini_set('display_errors', 1); 
    error_reporting(E_ALL);

    //phpinfo();

    echo DB_NAME ."<br>";
    echo DB_USER ."<br>";
    echo DB_PASSWORD ."<br>";
    echo DB_HOST."<br>";


    $conn = mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD,DB_NAME);
    // database port is also 3306 which is default

    if (!$conn) {
        echo  "Connection failed: " . mysqli_connect_error();
    }
    echo "Connected successfully";

    ?>

使用此代码。您在DB_HOST."<br>"行末尾错过了半冒号。代码中的每件事都很好。

<?php

require_once ($_SERVER['DOCUMENT_ROOT'].'/wp-config.php');

ini_set('display_errors', 1); 
error_reporting(E_ALL);

//phpinfo();

echo DB_NAME ."<br>";
echo DB_USER ."<br>";
echo DB_PASSWORD ."<br>";
echo DB_HOST."<br>";


$conn = mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD,DB_NAME);
// database port is also 3306 which is default

if (!$conn) {
    echo  "Connection failed: " . mysqli_connect_error();
}
echo "Connected successfully";

?>

添加mysqli_connect（）函数会停止运行脚本
