Question

我在程序PHP应用程序中第一次使用mysqli。对不起复杂的层次结构。以下是它的结构。

index.php 包括 config.php 包含 db_conn.php
index.php 包括 gallery.php

的index.php

include('config.php');

<html>
<body>
    <?php include('gallery.php');?>
</body>
</html

的config.php

include('db_conn.php');
include('setttings.php')
#more code..

db_conn.php

?php
$con=mysqli_connect("localhost","my_user","my_password","my_db");
// Check connection
if (mysqli_connect_errno())
{
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
}

gallery.php

$sql_pa = "SELECT * FROM `pasal` WHERE `deleted` = 0 ORDER BY `datetime`";
$query_pa = mysqli_query($con, $sql_pa);
# more code...

所以我的连接存储在位于 db_conn.php 文件中的变量 $ con 中，该文件在 gallery.php中不可用文件。我该如何解决？

db_conn.php

    apply plugin: 'com.android.application'

dependencies {

    compile ('com.google.android.gms:play-services:9.0.2')
    compile 'com.android.support:appcompat-v7:24.0.0'
    compile files('libs/appcompat_v7.jar')
    compile files('libs/ksoap2-android-assembly-2.5.8-jar-with-dependencies.jar')
    compile files('libs/gcm.jar')
    compile files('libs/android.jar')
    compile files('libs/activation.jar')
    compile files('libs/additionnal.jar')

    compile ('com.google.android.gms:play-services-analytics:9.0.2')
    compile files('libs/libGoogleAnalyticsServices.jar')
    compile files('libs/mail.jar')
    compile "com.android.support:support-v4:24.0.0"
    compile "com.android.support:design:24.0.0"
    compile 'com.android.support:multidex:1.0.1'
}

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.2'
    }
}

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"
    useLibrary  'org.apache.http.legacy'

    defaultConfig {

        applicationId "com.expedite.apps.vedant"
        minSdkVersion 9
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
        multiDexEnabled true
    }


    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }

        // Move the tests to tests/java, tests/res, etc...
        instrumentTest.setRoot('tests')

        // Move the build types to build-types/<type>
        // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
        // This moves them out of them default location under src/<type>/... which would
        // conflict with src/ being used by the main source set.
        // Adding new build types or product flavors should be accompanied
        // by a similar customization.
        debug.setRoot('build-types/debug')
        release.setRoot('build-types/release')
    }
}

gallery.php

$con

双N

无法使用存储在另一个文件中包含的包含文件中的mysqli连接？
