ThinkPHP3.2.3 extended QR code, thinkphp3.2.3 extension

First, the path is set.

Simple to use no Logo:

Public Function QRCode () {        Vendor (' Phpqrcode.phpqrcode ');        Generate QR code image        $object = new \qrcode ();        $url = ' http://www.shouce.ren/';//URL or text content        $level =3;        $size =4;        $errorCorrectionLevel =intval ($level);//Fault tolerance level        $matrixPointSize = Intval ($size);//Generate picture size        $object->png ($ URL, False, $errorCorrectionLevel, $matrixPointSize, 2);    }

Advanced use with Logo:

Public Function QRCode () {Vendor (' phpqrcode.phpqrcode ');        Generate QR code image $object = new \qrcode ();        $qrcode _path= ';        $file _tmp_name= ';        $errors =array (); if (!empty ($_post)) {$content = Trim ($_post[' content ');//two-D code content $contentSize = $this->getstringleng            Th ($content); if ($contentSize >150) {$errors []= ' word is too long and cannot be more than 150 characters!
