看文档会发现模板变量都不在了,tp6已经把功能全部模块化了,很多东西都独立了出去,模板也一样
须要看模板单独的文档:https://www.kancloud.cn/manual/think-template/1286403

须要把模板组件加入框架

composer require topthink/think-template

在配置文件view.php里面加一个tpl_replace_string配置项

'tpl_replace_string'  =>  [
    '__THEMES__'=>'/static/frontend/theme',
    '__STATIC__'=>'/static',
    '__JS__' => '/static/javascript',
]

使用thinkTemplate模板引擎

新版框架默认只能支持PHP原生模板,如果需要使用thinkTemplate模板引擎,需要安装think-view扩展(该扩展会自动安装think-template依赖库)。

composer require topthink/think-view

方法一:

"mysql:host=$host;dbname=$db;charset=utf8"

注意: 方法一在低版本php中不适应 php 5.3.6
方法二:

$dbh = new PDO("mysql:$connstr",  $user, $password);
$dbh->exec("set names utf8");

ps:不设置,中文可能出现乱码

function RandomFile($folder='', $extensions='.*'){
  // fix path:
  $folder = trim($folder);
  $folder = ($folder == '') ? './' : $folder;
  // check folder:
  if (!is_dir($folder)){ die('invalid folder given!'); }
  // create files array
  $files = array();
  // open directory
  if ($dir = @opendir($folder)){
    // go trough all files:
    while($file = readdir($dir)){
      if (!preg_match('/^\.+$/', $file) and 
        preg_match('/\.('.$extensions.')$/', $file)){
        // feed the array:
        $files[] = $file;        
      }      
    }    
    // close directory
    closedir($dir);  
  }
  else {
    die('Could not open the folder "'.$folder.'"');
  }
  if (count($files) == 0){
    die('No files where found :-(');
  }
  // seed random function:
  mt_srand((double)microtime()*1000000);
  // get an random index:
  $rand = mt_rand(0, count($files)-1);
  // check again:
  if (!isset($files[$rand])){
    die('Array index was not found! very strange!');
  }
  // return the random file:
  return $folder . $files[$rand];
}

//用法演示:
// "jpg|png|gif" matches all files with these extensions
print RandomFile('test_images/','jpg|png|gif');
// returns test_07.gif
// ".*" matches all extensions (all files)
print RandomFile('test_files/','.*');
// returns foobar_1.zip
// "[0-9]+" matches all extensions that just 
// contain numbers (like backup.1, backup.2)
print RandomFile('test_files/','[0-9]+');
// returns backup.7
