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
1 <?php 2 require \'class/csv.php\'; 3 require \'class/Encrypt.php\'; 4 $args = getopt(\'f:\'); 5 $file = isset($args[\'f\']) ? trim($args[\'f\']) : \'\' ; 6 if(empty($file)){ 7 exit("please input file " ); 8 } 9 if(!file_exists(dirname(__FILE__) . "/csv/$file" ) ){ 10 exit($file . "---is not exists " ); 11 } 12 13 $csvreader = new CsvReader(dirname(__FILE__) . "/csv/" . $file); 14 15 $data = $csvreader->get_data(1000 , 0 ); 16 17 if(empty($data) ){ 18 exit("file content is empty "); 19 } 20 $folder = "/opt/data/site/export/file/" ;//创建文件的地址 21 $date = date("YmdHis" , time() ); 22 $f = $folder . "/" . $date ; 23 mkdir( $f ); 24 foreach($data as $key => $value ){ 25 $url = isset($value[0]) ? trim($value[0]) : \'\' ; 26 $name = isset($value[1]) ? trim($value[1]) : \'\' ; 27 $url = Encrypt::AuthCode($url , "DECODE" , "*******@123reu!@^%" );//解密方式 28 if(empty($name) OR empty($url ) ){ 29 continue ; 30 } 31 // echo $url ; 32 // echo "\n"; 33 $commend = "/usr/local/wkhtmltox/bin/wkhtmltopdf \'{{$url}}\' {$f}/{$name}.pdf &"; 34 system($commend );//调用系统命令 35 echo "export url is {$url} \n"; 36 } 37 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：
1 <?php 2 /** 7 */ 8 class CsvReader { 9 private $csv_file; 10 private $spl_object = null; 11 private $error; 12 13 public function __construct($csv_file = \'\') { 14 if($csv_file && file_exists($csv_file)) { 15 $this->csv_file = $csv_file; 16 } 17 } 18 19 public function set_csv_file($csv_file) { 20 if(!$csv_file || !file_exists($csv_file)) { 21 $this->error = \'File invalid\'; 22 return false; 23 } 24 $this->csv_file = $csv_file; 25 $this->spl_object = null; 26 } 27 28 public function get_csv_file() { 29 return $this->csv_file; 30 } 31 32 private function _file_valid($file = \'\') { 33 $file = $file ? $file : $this->csv_file; 34 if(!$file || !file_exists($file)) { 35 return false; 36 } 37 if(!is_readable($file)) { 38 return false; 39 } 40 return true; 41 } 42 43 private function _open_file() { 44 if(!$this->_file_valid()) { 45 $this->error = \'File invalid\'; 46 return false; 47 } 48 if($this->spl_object == null) { 49 $this->spl_object = new SplFileObject($this->csv_file, \'rb\'); 50 } 51 return true; 52 } 53 54 public function get_data($length = 0, $start = 0) { 55 if(!$this->_open_file()) { 56 return false; 57 } 58 $length = $length ? $length : $this->get_lines(); 59 $start = $start - 1; 60 $start = ($start < 0) ? 0 : $start; 61 $data = array(); 62 $this->spl_object->seek($start); 63 while ($length-- && !$this->spl_object->eof()) { 64 $data[] = $this->spl_object->fgetcsv(); 65 $this->spl_object->next(); 66 } 67 return $data; 68 } 69 70 public function get_lines() { 71 if(!$this->_open_file()) { 72 return false; 73 } 74 $this->spl_object->seek(filesize($this->csv_file)); 75 return $this->spl_object->key(); 76 } 77 78 public function get_error() { 79 return $this->error; 80 } 81 }
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。
