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(1000 , 0 );

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[0]) ? trim($value[0]) : '' ;
    $name = isset($value[1]) ? trim($value[1]) : '' ;
    $url = Encrypt::AuthCode($url , "DECODE" , "*******@123reu!@^%" );//解密方式
    if(empty($name) OR empty($url ) ){
        continue ;
    }
//    echo $url ;
//    echo "
";
    $commend = "/usr/local/wkhtmltox/bin/wkhtmltopdf '{{$url}}' {$f}/{$name}.pdf &";
    system($commend );//调用系统命令
    echo "export url is {$url} 
";
}
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
/** 7  */
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 = 0, $start = 0) {
        if(!$this->_open_file()) {
            return false;
        }
        $length = $length ? $length : $this->get_lines();
        $start = $start - 1;
        $start = ($start < 0) ? 0 : $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。
