Three PHP tutorial multi-File Upload instance code
In the PHP development application often encounter file upload this need, and sometimes will encounter to upload more files, below we come to see I provide three PHP multi-file Upload instance code, good crap don't say more to see these multi-file upload function suitable for you.

Example code:

The name must be "[]"

Sets the types of files that are allowed to be uploaded by users.
$type = Array (' gif ', ' jpg ', ' png ', ' zip ', ' rar ');
$upload = new UploadFile ($_files[' uploadfile '), '/', 1024*1024, $type);
Parameter description: 1: File of the form, 2: Upload directory, 3: Support file Size, 4: Allow file type
$icount = $upload->upload ();
if ($icount > 0) {//upload successful
Print_r ($upload->getsaveinfo ());
*/

Class UploadFile {
var $postfile = array (); User-uploaded files
var $custompath = ""; Custom File Upload Path
var $maxsize = ""; Maximum file size
var $lasterror = ""; Last error message
var $allowtype = array (' gif ', ' jpg ', ' png ', ' zip ', ' rar ', ' txt ', ' Doc ', ' pdf ');
var $endfilename = ""; The last saved file name
var $saveinfo = array (); Save the final information for a file
var $root _dir = ""; The location of the project on the hard disk

/**
* Constructor function
* @access Public
*/

function UploadFile ($arrfile, $path = "_", $size = 2097152, $type = 0) {
$this->postfile = $arrfile;
$this->custompath = $path = = "_"? "": $path;
$this->maxsize = $size;
if ($type!=0) $this->allowtype = $arrfile;
$this->root_dir = $_server[' document_root ');
$this->_mkdir ($this->custompath);
}

/**
* Core code for File upload
* @access Public
* Number of successful files @return int upload
*/

Function upload () {
$ilen = sizeof ($this->postfile[' name '),
for ($i =0; $i < $ilen; $i + +) {
if ($this- >postfile[' ERROR ' [$i] = = 0) {//Upload no error occurred
//Take the current file name, temporary file name, size, extension, which will be used later.
$sname = $this->postfile[' name ' [$i];
$stname = $this->postfile[' tmp_name ' [$i];
$isize = $this->postfile[' size ' [$i];
$stype = $this->postfile[' type ' [$i];
$sextn = $this->_getextname ($sname);

//detects whether the current upload file size is legitimate.
if ($this->_checksize) {
$this->lasterror = "The file you uploaded [". $sname. "], over the system support size!";
$this->_showmsg ($this->lasterror);
Continue;
}

if (!is_uploaded_file ($stname)) {
$this->lasterror = "Your files are not uploaded by normal means!";
$this->_showmsg ($this->lasterror);
Continue
}
$_filename = basename ($sname, ".". $SEXTN). " _ ". Time ().". $sextn;
$this->endfilename = $this->custompath.$_filename;

if (!move_uploaded_file ($stname, $this->root_dir. $this->endfilename)) {
$this->lasterror = $this->postfile[' ERROR ' [$i];
$this->_showmsg ($this->lasterror);
Continue
}

Stores information about the current file so it can be called by other programs.
$this->save_info[] = Array ("name" = = $sname, "type" = = $sextn, "size" = = $isize, "path" = = $this->endfil ENAME);
}
}

return sizeof ($this->save_info);
}
