Let you upload 1000 files at the same time (2)_PHP tutorial

Now that the file submission page has been generated, the following task is clear: save the submitted file content to the server.

Below we use two methods to implement this function:

1. Use PHP to save:
We first define a file saving function fup() which has two parameters:
$filename: file content
$fname: file name (including path)
The rest is to write a loop to write the files to the server in sequence. Here is a brief explanation:
PHP handles uploaded files like this: If the submitted file box is file0, then the content of the file submitted to PHP is saved in the variable $file0, and the file name is saved in $file0_name middle. In this way, what I have to do in this loop is to decompose the content submitted on the submission page. Please see the code below for the implementation process.

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

for($i=0;$i<$cnt;$i++)
{
$ffnn="file".$i;
$ffnnname=$ffnn."_name";
$ ffpath="path".$i;

                                                                                              $ffnn,$$ffpath.$$ffnnname); //"../www/test/tmp/"
}
?>
------------ -------------------------------------------------- --------

2. Use PERL to save:
The principles of their implementation are exactly the same. I won’t go into details here. Please look at the code:

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;

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

for ($i=0;$i<$cntfile;$i++ ){
$paramfile = 'file'.$i;
$parampath='path'.$i;

$written=param($parampath);

&upfile ;
                                           ;<<<<<<<
sub upfile
{
$maxdata = 512000;
# $written = ' ../www/test/tmp/';


$strRFname=reverse $xfile;
$intIndex=index($strRFname,''); $strRFname,0,$intIndex);
$strNetFname=scalar reverse $strNetFname;


if((stat $xfile)[7]>$maxdata){
print " Status: 411 Size Not Allowedn" . "Content-Type: text/htmlnAllow: POSTnn" .
"< /head>

You got big problem. Try again.

n";
 
binmode $xfile;
use File::Copy;
copy($xfile,$written.$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!

';
}
