本文实例讲述了PHP QRCODE生成彩色二维码的方法。分享给大家供大家参考,具体如下:

这里重写了下PHPQRCODE,精简了部分代码,合并PNG GIF JPEG的输出.

参数说明:

调用方式:
复制代码 代码如下:QRcode::IMGout($text, $outfile = false, $level = QR_ECLEVEL_L, $size = 3, $col=array(array(255,255,255),array(0,0,0)),$margin =2, $saveandprint=false,$logo=false,$bg=false,$type='png');

$text  字符串
$outfile = false

输出文件

$level = L  容错 L 7%  M 15%  Q 25%  H 30%
$size = 3  每个像素点大小
$col=array(array(255,255,255),array(0,0,0))

颜色多维数组RBG

[0] 背景色  array(r,g,b)
[1] 左上角周围  array(r,g,b)
[2] 右上角周围  array(r,g,b)
[3] 左下角周围  array(r,g,b)
[4] 左上角中心  array(r,g,b)
[5] 右上角中心  array(r,g,b)
[6] 左下角中心  array(r,g,b)
[7] 内容  array(r,g,b)
[8] 内容色是否变化//暂未写代码,保留

$margin = 2  //四周边距
$saveandprint=false

$outfile为true时是否同时输出

$logo=false LOGO图像地址 //LOGO高大于宽自动裁剪 圆角透明没写好
$bg=false //背景图像数组

Copy after login

[0] 图像地址
[1] 背景宽 0为不变
[2] 背景高 0为保持宽高比
[3] LOGO宽与背景宽高较小值的比值 例0.8为80%
[4] LOGO距背景左边边距 0为居中 右边超出自动往左
[5] LOGO距背景上边边距 0为居中 下边超出自动往上

$type='png'  输出类型 PNG GIF JPG
