PHP implementation File upload php file upload plugin php file upload plugin php ftp upload text

The tool classes are as follows:

 MaxSize = $maxSize; $this->allowmime = $allowMime; $this->allowext = $allowExt; $this->uploadpath = $uploadPath; $this->imgflag = $imgFlag; $this->init ();} Private Function init () {$this->fileinfo = array (); foreach ($_files as $k = = $v) {$this->fileinfo = $v;} if (!empty ($this->fileinfo)) {$this->ext = Strtolower (pathinfo ($this->fileinfo[' name '], pathinfo_extension ));}} /*** Upload file * @return If the upload fails then return false, if the upload succeeds, then the return path */public function UploadFile () {if (! $this->checkerror () | |! $this- >checksize () | | ! $this->checkhttppost () | | ! $this->checktrueimg ()) {return false;} if (!empty ($this->allowext) &&! $this->checkext ()) {return false;} if (!empty ($this->allowmime) &&! $this->checkmime ()) {return false;} $this->checkuploadpath (); $this->uniname = $this->getuniname (); $this->destination = $this Uploadpath.

Here's how to use it:

 
  File Upload

 
  UploadFile (); if (! ( $destination = = = False) {echo "$destination";} echo $uploadHelper->geterror ();?>

The above describes the PHP implementation of file upload, including file Upload, PHP content, I hope that the PHP tutorial interested in a friend helpful.
