Symfony method for generating two-dimensional code _php example

The method of generating two-dimensional code by Symfony is described in this paper. Share to everyone for your reference, specific as follows:

There are a lot of examples of using PHP to generate two-dimensional code on the Web, mainly in two ways:

The first: Google Open API, as follows:

$urlToEncode = "http://blog.it985.com";
Generateqrfromgoogle ($urlToEncode);
function Generateqrfromgoogle ($chl, $widhtHeight = ' m ', $EC _level = ' L ', $margin = ' 0 ')
{
  $url = UrlEncode ($url) ;
  Echo '

Second: Using PHP class library PHP QR CODE

How to use:

<?php
//include one of these two files:/
* qrlib.php for full
version (also your have to provide all library files
form Package plus cache dir)
OR phpqrcode.php for merged version (only one file,
but slower and less code BEC Ause disabled cache
and quicker masking configured)
* *//
/Two sentence explanation://////
with qrlib.php words need to be put together with other files: files, folders.
//phpqrcode.php is a merged version that only needs to include this file, but the resulting picture is slow and inaccurate including
('./phpqrcode/phpqrcode.php ');
Here are two uses:
//Create a two-dimensional code file
QRCode::p ng (' Code data text ', ' filename.png ');
Creates file
//Generate picture to browser
qrcode::p ng (' some othertext 1234 ');

Of course, there are other ways to generate two-dimensional code, this is not one of the introduction.

Let's talk about using Endroidqrcodebundle to generate two-dimensional code under Symfony:

1, the use of composer installation

Copy Code code as follows:

Composer require Endroid/qrcode-bundle

2. Register in kernel

<?php
//app/appkernel.php public
function Registerbundles ()
{
  $bundles = array (
    //...
    ) New Endroid\bundle\qrcodebundle\endroidqrcodebundle (),
  );
}

3. Define Access Routing

Endroidqrcodebundle:
  resource:  "@EndroidQrCodeBundle/controller/"
  type:    annotation
  Prefix:   /qrcode

4. Configure Config.xml

Endroid_qr_code:
  size:100
  padding:10
  extension:gif
  error_correction_level:high
  Foreground_color: {r:0, g:0, b:0, a:0}
  background_color: {r:255, g:255, b:255, a:0}
  #label: "My Labe L "
  #labelFontSize: 16

5. Use in twig

Normal text generation method:
