PHP QRCODE生成彩色二维码的方法,phpqrcode生成
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
[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

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
