Jun 13, 2016 am 09:32 AM
import thinkphp

下面附上import的幾個用法介紹

1、用法一

import('@.Test.Translate');
@,表示項目根目錄。假定根目錄是:App/
導入類庫的路徑是:App/Lib/Test/Translate.class.php
結論:import('@')是相對于項目目錄的Lib目錄而言

2、用法二

import('Think.Test.Translate');
Think,表示系統(tǒng)根目錄。既是:./ThinkPHP/
導入類庫的路徑是:./ThinkPHP/Lib/Test/Translate.class.php
結論:import('Think')是相對于系統(tǒng)目錄的Lib目錄而言

3、用法三

import('ORG.Test.Translate');

import('COM.Test.Translate');
ORG, 第三方公共類庫目錄
COM, 企業(yè)公共類庫目錄
兩種寫法都是相對于./ThinkPHP/Extend/Library/ 而言。
導入類庫的路徑是:./ThinkPHP/Extend/Library/ORG/Test/Translate.class.php

導入類庫的路徑是:./ThinkPHP/Extend/Library/COM/Test/Translate.class.php

結論:import('ORG')或import('COM')是相對于系統(tǒng)擴展類庫目錄而言(./ThinkPHP/Extend/Library/)

4、用法四

import('Blog.Test.Translate');
這種寫法既不是@,Think的寫法,有不是ORG,COM的寫法,會被當作分組的項目目錄來處理。
解析結果是:App/../Blog/Lib/Test/Translate.class.php
結論:第四種寫法,是相對于分組項目目錄的Lib目錄而言的寫法。

5、用法五

import還支持別名導入,使用別名導入,首先先定義別名文件,在項目配置目錄下建立alias.php,定義項目中需要用到的類庫別名。

return array(
'page' => LIB_PATH.'Common/page.class.php',
);

//這樣使用即可
import('page');
