Thinkphp Integration Series of Phpqrcode to generate two-dimensional code

PHP generated QR code is actually very simple, of course, refers to the use of QRCode class library;

So about whether to write this blog, I hesitated repeatedly;

But finally decided to write down, if there are children's shoes urgently use, it can be directly cited;

Another can also be written as the article to pay the generated two-dimensional code to do a cushion;

The usual; example of a bjyadmin project: Http://git.oschina.net/shuaibai123/thinkphp-bjyadmin

1: First copy the Phpqrcode folder under/thinkphp/library/vendor/to its own project;

2:/application/common/common/function.php Add the following function

/** * Generate QR Code * @param string $url URL connection * @param integer $size size Pure digital */function qrcode ($url, $size =4) {Vendor (' PHPQR    Code.phpqrcode ');    If there is no HTTP, add if (Strpos ($url, ' http ') ===false) {$url = ' http://'. $url; } QRCode::p ng ($url, false,qr_eclevel_l, $size, 2,false,0xffffff,0x000000);}

Then directly call the QRCode ($url, $size) function, the first parameter to link, the second parameter to the size of A;

3: It is possible to generate two-dimensional code here, if you want to personalize the QR code more customized;

Then the following is to explain the role of the stack of parameters;

PNG ($text, $outfile = False, $level = qr_eclevel_l, $size = 3, $margin = 4, $saveandprint =false, $back _color = 0xFFFFFF, $ Fore_color = 0x000000)

The first parameter is $text; the URL parameter in the above code;

The second parameter $outfile default is no, no file is generated, only the QR code image is returned;

The third parameter, $level, defaults to L; This parameter can pass values of L (qr_eclevel_l,7%), M (qr_eclevel_m,15%), Q (qr_eclevel_q,25%), H (qr_eclevel_h,30%), respectively. ; This parameter controls the fault tolerance of the two-dimensional code; Different parameters represent the percentage of the area where the QR code can be overwritten. The fault-tolerance ratio of two-dimensional code is used; we can place the avatar in any area of the generated QR code image;

The fourth parameter $size; controls the size of the generated picture; default is 4;

The fifth parameter $margin; control the size of the blank area of the generated QR code;

The sixth parameter $saveandprint; Save the image of the QR code and display it; $outfile must pass the picture path;

Seventh parameter $back_color; background color;

The eighth parameter $fore_color; draw the color of the two-dimensional code;

Note: The seventh and eighth parameters need to be 16 binary is the color value, and to replace "#" with "0x"
Give me a chestnut:
White: #FFFFFF = 0xFFFFFF
Black: #000000 = 0x000000
