php批量导出pdf文件的脚本（html-PDf）

背景：突然有大量的文件需要导出成PDF文件，写一个批量导出pdf的脚本，同时文件的命名也需要有一定的规则

导出方式：向服务器中上传csv文件，csv文件中包含文件的地址和相对应的文件命名。

如下格式：(地址是已经加密的)

导出的文件 index.php

 <?php
 require 'class/csv.php';
 require 'class/Encrypt.php';
 $args = getopt('f:');
 $file = isset($args['f']) ? trim($args['f']) : '' ;
 if(empty($file)){
     exit("please input file " );
 }
 if(!file_exists(dirname(__FILE__) . "/csv/$file"  ) ){
     exit($file . "---is not exists " );
 }

 $csvreader = new CsvReader(dirname(__FILE__) . "/csv/" . $file);

 $data = $csvreader->get_data( ,  );

 if(empty($data) ){
     exit("file content is empty ");
 }
 $folder = "/opt/data/site/export/file/" ;//创建文件的地址
 $date = date("YmdHis" , time() );
 $f = $folder . "/" . $date ;
 mkdir( $f );
 foreach($data as $key => $value ){
     $url = isset($value[]) ? trim($value[]) : '' ;
     $name = isset($value[]) ? trim($value[]) : '' ;
     $url = Encrypt::AuthCode($url , "DECODE" , "*******@123reu!@^%" );//解密方式
     if(empty($name) OR empty($url ) ){
         continue ;
     }
 //    echo $url ;
 //    echo "\n";
     $commend = "/usr/local/wkhtmltox/bin/wkhtmltopdf '{{$url}}' {$f}/{$name}.pdf &";
     system($commend );//调用系统命令
     echo "export url is {$url} \n";
 }
 echo "OK-----success";

$args = getopt('f:');函数是读取shell脚本的 参数
例如: index.php -f 11.csv  直接读取csv文件夹中的11.csv文件，进行数据导出
csv类如下：

 <?php
 /**

  * @Date:   2017-02-06 10:49:26

 class CsvReader {
     private $csv_file;
     private $spl_object = null;
     private $error;

     public function __construct($csv_file = '') {
         if($csv_file && file_exists($csv_file)) {
             $this->csv_file = $csv_file;
         }
     }

     public function set_csv_file($csv_file) {
         if(!$csv_file || !file_exists($csv_file)) {
             $this->error = 'File invalid';
             return false;
         }
         $this->csv_file = $csv_file;
         $this->spl_object = null;
     }

     public function get_csv_file() {
         return $this->csv_file;
     }

     private function _file_valid($file = '') {
         $file = $file ? $file : $this->csv_file;
         if(!$file || !file_exists($file)) {
             return false;
         }
         if(!is_readable($file)) {
             return false;
         }
         return true;
     }

     private function _open_file() {
         if(!$this->_file_valid()) {
             $this->error = 'File invalid';
             return false;
         }
         if($this->spl_object == null) {
             $this->spl_object = new SplFileObject($this->csv_file, 'rb');
         }
         return true;
     }

     public function get_data($length = , $start = ) {
         if(!$this->_open_file()) {
             return false;
         }
         $length = $length ? $length : $this->get_lines();
         $start = $start - ;
         $start = ($start < ) ?  : $start;
         $data = array();
         $this->spl_object->seek($start);
         while ($length-- && !$this->spl_object->eof()) {
             $data[] = $this->spl_object->fgetcsv();
             $this->spl_object->next();
         }
         return $data;
     }

     public function get_lines() {
         if(!$this->_open_file()) {
             return false;
         }
         $this->spl_object->seek(filesize($this->csv_file));
         return $this->spl_object->key();
     }

     public function get_error() {
         return $this->error;
     }
 }

原理：获取csv文件中的内容，创建保存数据的文件夹，通过导出类来导出文件。
