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!
';
}

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.
