Question

我正在使用共享主机。这里我创建了config.ini文件在<properties>  <jvm.args>-XX:MaxMetaspaceSize=64m -Xloggc:logs/gc_%p_%t.log</jvm.args> <derby.version>USE_REQUIRED_JRE8_DERBY_VERSION</derby.version> </properties> ... <profiles> <profile> <activation> <jdk>1.7</jdk> </activation> <properties> <jvm.args>-XX:MaxPermSize=64m -Xloggc:logs/gc.log</jvm.args> <derby.version>10.12.1.1</derby.version> </properties> </profile> </profiles>中包含连接信息。

在默认文件夹中复制了/home/kkits996/private/config.ini和dbconnection.php 当我运行dbconcheck来检查dbconnection并检索表数据时它没有显示表格cruduser的获取结果表中的回显值未显示。

dbconnect.php

dbconcheck.php

dbconcheck.php

<?php
function db_connect() {

    // Define connection as a static variable, to avoid connecting more than once 
    static $connection;

    // Try and connect to the database, if a connection has not been established yet
    if(!isset($connection)) {
        // Load configuration as an array. Use the actual location of your configuration file
        //    $config = parse_ini_file('/home/kkits996/private/config.ini'); 
        $connection = mysqli_connect($config['servername'],$config['username'],$config['password'],$config['dbname']);
    }

    // If connection was not successful, handle the error
    if($connection === false) {
        // Handle error - notify administrator, log to a file, show an error screen, etc.
        return mysqli_connect_error(); 
    }
    return $connection;
}

// Connect to the database
$connection = db_connect();

// Check connection
if ($connection->connect_error) {
    die("Connection failed: " . $connection->connect_error);
}
?>

从config.ini访问数据库连接和查询表数据的数据库信息
