PHP压缩一个文件夹里面所有的文件，多文件混合压缩

PHP压缩一个文件夹里面所有的文件，多文件混合压缩

p.s. 文件打包，文件夹打包，文件夹加文件压缩，zip函数      

前言...

找了好久，都没找到适合自己的函数，遂自建一个。

本函数可以接受多个源文件(或文件夹)同时压缩，例如使用数组传值：

$zip_result = createZip( array('A.php', 'B.txt', 'logo.png', '/var/www/assets/css/'),      'result.zip' );

$zip_result = createZip( ‘/path-to-source-folder/’,  'result.zip' );

$zip_result = createZip( 'index.html',      'result.zip' );

注意：

* 1.需要两个自建函数配合：createZip()  +   recursive_get_files_by_path_of_folder() 

* 2.主函数一个输出的结果$return['data']['zipFile']['url']需要自己去补充，现在为空。（可选）

代码：

<?php

/**
*
* createZip - 创建压缩包，for文件夹／文件
*
* @param type string-or-array $from
*        => 字符串 '/path/to/source/file/or/folder/'
*        => 或者 包含字符串的数组  array('fileA','FolderA','fileB')
* @param type string $to
*        => 字符串 '/path/to/output.zip'
* @return array
*        => array(
*             'success' => false,
*             'message' => '失败原因',
*             'data' => array(
*                 'zipFile' => array(zip文件的信息)
*             )
*           )
