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" .
"
You got big problem. Try again.
n";exit 0;
}
binmode $xfile;
use File::Copy;
copy($xfile,$writed.$strNetFname);
}
sub g_head{
print '
文件上传结果(Upload Result) | ||
SourceFile: | ';DestFile: | ';Upload | ';
'.$xfile .' | ';'.$writed.$strNetFname.' | ';OK! | ';
}

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
