HomeBackend DevelopmentPHP Tutorial让你同时上传 1000 个文件 (二)

文件提交页面既已生成,下面任务就很明确了:将提交的文件内容保存到服务器上。

下面我们用两种方法来实现这个功能:

1. 用 php 来保存:
我们先定义一个文件保存函数 fup() 它有两个参数:
   $filename: 文件内容
   $fname: 文件名(包含路径)
剩下的就是写一个循环将文件依次写入服务器。这里要简单说明一下:
PHP 对于上传文件的处理是这样的:如果提交的文件框我为 file0, 那么提交给 PHP 的文件内容保存在变量 $file0 中,而文件名则保存在 $file0_name 中。这样在这个循环中我要做的就是将提交页面提交的内容分解出来,实现过程请看下面的代码。

fileup.php
----------------------------------------------------------------------

  function fup($filename,$fname)
  {    If($filename != "none") {
        copy($filename,$fname);
        unlink($filename); 
      }
  }

  for($i=0;$i   {
    $ffnn="file".$i;
    $ffnnname=$ffnn."_name";
    $ffpath="path".$i;
     
    //PRint $$ffnn;
    print $$ffnnname;
    print "
";
     
    fup($$ffnn,$$ffpath.$$ffnnname); //"../www/test/tmp/"
  }
?>
----------------------------------------------------------------------

2. 用 PERL 来保存:
它们实现的原理完全一样,在此不多说,请看代码:

fileup.cgi(fileup.pl)
----------------------------------------------------------------------
#!/usr/bin/perl 

use CGI qw/:standard/; 

if ($ENV{'CONTENT_TYPE'} !~ /multipart/form-data/) { 
 print "Cache-Control: no-cachenPragma: no-cachen" . 
  "Content-Type: text/htmlnn" . 
  "Your web browser cannot upload files. Sorry."; 
 exit 0; 
}


$cntfile=param('cnt');
print header; 
print start_html; 
#print "Receiving Please wait....";

&g_head;

#$writed = '../www/test/tmp/';

for ($i=0;$i   $paramfile = 'file'.$i;
  $parampath='path'.$i;
   
  $writed=param($parampath);

  &upfile;
  &g_body;
}

&g_bott;

#
sub upfile
{
  $maxdata = 512000; 
#  $writed = '../www/test/tmp/'; 


  $strRFname=reverse $xfile;
  $intIndex=index($strRFname,'\');
  $strNetFname=substr($strRFname,0,$intIndex);
  $strNetFname=scalar reverse $strNetFname;
   
   
  if((stat $xfile)[7]>$maxdata){ 
    print "Status: 411 Size Not Allowedn" . 
      "Content-Type: text/htmlnAllow: POSTnn" . 
      "411 411 Size Not Allowed

You got big problem. Try again.

n"; 
    exit 0; 
  } 
   
   
  binmode $xfile; 
  use File::Copy; 
  copy($xfile,$writed.$strNetFname); 
}

sub g_head{
  print '';
  print '';
  print '';
  print '  ';
  print '  ';
  print '  ';
  print '';
}

sub g_body{
  print '';
  print '  ';
  print '  ';
  print '  ';
  print '';
}

sub g_bott{
  print '
文件上传结果(Upload Result)
SourceFile:DestFile:Upload
'.$xfile .''.$writed.$strNetFname.'OK!
';
}
