yii2 配置加速 – N个配置文件生成一个配置文件

yii2的配置方式是N个配置文件，最终通过merge函数合并成一个php数组，如果只有几个配置文件，不会占用太多资源，如果像fecshop这类电商系统，有大量的配置文件，因此需要合并N个配置文件成一个配置文件，具体实现如下：

首先新建文件@app/merge_config.php 设置可写权限， 然后新建文件 @app/web/index-merge-config.php，将index.php的内容复制过来，在 代码：$config = yii\helpers\ArrayHelper::merge函数后面，添加下面的代码，这些代码的用处是将$config数组的内容重新写成php代码保存到文件@app/merge_config.php中

$str = '<?php '.PHP_EOL;
$str .= 'return '.PHP_EOL;

function toPhpCode($arr,$i=0){
  $i++;
  $tb_i = $i*4;
  $tb = ($i-1)*4;
  $tb1_str = '';
  $tb2_str = '';
  for($j=0;$j<$tb;$j++){
    $tb1_str .= ' ';
  }
  for($jj=0;$jj<$tb_i;$jj++){
    $tb2_str .= ' ';
  }
  $mystr = '';
  if(is_array($arr) && !empty($arr)){
    $mystr .= PHP_EOL .$tb1_str.'['.PHP_EOL;
    $t_arr = [];
    foreach($arr as $k => $v){
      $key 	= '';
      $value 	= '';
      if(is_string($k)){
        $key = "'".$k."'";
      }else{
        $key = $k;
      }
      if(is_array($v) && !empty($v)){
        $value = toPhpCode($v,$i);
      }else if(is_array($v) && empty($v)){
        $value = '[]';
      
      }else{
        if(is_string($v)){
          $value = "'".$v."'";
        }else if(is_bool($v)){
          if($v){
            $value = 'true';
          }else{
            $value = 'false';
          }
        }else{
          if(is_null($v)){
            $v = "''";
          }
          $value = $v;
        }
        
      }
      $t_arr[] = $tb2_str.$key."=>".$value;
    }
    $mystr .= implode(','.PHP_EOL,$t_arr);
    $mystr .= PHP_EOL .$tb1_str.']'. PHP_EOL;
  }
  return $mystr;
}


$str .= toPhpCode($config);
$str .= ';';

echo 'generate merge config file success';
file_put_contents('../merge_config.php', $str);
echo 'generate merge config file success';

执行这个文件后，就会将$config数组的内容，以php代码的方式写入到merge_config.php，这样就生成了单文件配置。

在index.php中加载单文件配置

$use_merge_config_file = true;

if($use_merge_config_file){
  $config = require('../merge_config.php');
}else{
  $config = yii\helpers\ArrayHelper::merge(
    require(__DIR__ . '/../../common/config/main.php'),
    require(__DIR__ . '/../../common/config/main-local.php'),
    require(__DIR__ . '/../config/main.php'),
    require(__DIR__ . '/../config/main-local.php'),
    # fecshop services config
    require(__DIR__ . '/../../vendor/fancyecommerce/fecshop/config/fecshop.php'),
    # fecshop module config
    require(__DIR__ . '/../../vendor/fancyecommerce/fecshop/app/appfront/config/appfront.php'),
    
    # thrid part confing
    
    # common modules and services.
    require(__DIR__ . '/../../common/config/fecshop_local.php'),
     
    # appadmin local modules and services.
    require(__DIR__ . '/../config/fecshop_local.php')
    
  );
}

这样就完成了。

 

下面fecshop的代码我粘贴一下：（供参考）

index.php：

error_reporting(E_ALL || ~E_NOTICE); //除去 E_NOTICE 之外的所有错误信息
ini_set('session.cookie_domain', '.fancyecommerce.com'); //初始化域名，
$http = ($_SERVER['SERVER_PORT'] == 443) ? 'https' : 'http';
$homeUrl = $http.'://'.$_SERVER['HTTP_HOST'].rtrim(dirname($_SERVER['SCRIPT_NAME']), '\\/');
