Laravel下生成验证码的类
本文实例为大家分享了Laravel生成验证码的类,供大家参考,具体内容如下
font=public_path().'/fonts/Elephant.ttf';//注意字体路径要写对,否则显示不了图片 $this->createCode(); } //生成随机码 privatefunctioncreateCode() { $_len=strlen($this->charset)-1; for($i=0;$i<$this->codelen;++$i){ $this->code.=$this->charset[mt_rand(0,$_len)]; } } //生成背景 privatefunctioncreateBg() { $this->img=imagecreatetruecolor($this->width,$this->height); $color=imagecolorallocate($this->img,mt_rand(157,255),mt_rand(157,255),mt_rand(157,255)); imagefilledrectangle($this->img,0,$this->height,$this->width,0,$color); } //生成文字 privatefunctioncreateFont() { $_x=$this->width/$this->codelen; for($i=0;$i<$this->codelen;++$i){ $this->fontcolor=imagecolorallocate($this->img,mt_rand(0,156),mt_rand(0,156),mt_rand(0,156)); imagettftext($this->img,$this->fontsize,mt_rand(-30,30),$_x*$i+mt_rand(1,5),$this->height/1.4,$this->fontcolor,$this->font,$this->code[$i]); } } //生成线条、雪花 privatefunctioncreateLine() { //线条 for($i=0;$i<6;++$i){ $color=imagecolorallocate($this->img,mt_rand(0,156),mt_rand(0,156),mt_rand(0,156)); imageline($this->img,mt_rand(0,$this->width),mt_rand(0,$this->height),mt_rand(0,$this->width),mt_rand(0,$this->height),$color); } //雪花 for($i=0;$i<100;++$i){ $color=imagecolorallocate($this->img,mt_rand(200,255),mt_rand(200,255),mt_rand(200,255)); imagestring($this->img,mt_rand(1,5),mt_rand(0,$this->width),mt_rand(0,$this->height),'*',$color); } } //输出 privatefunctionoutPut() { header('Content-type:image/png'); imagepng($this->img); imagedestroy($this->img); } //对外生成 publicfunctiondoimg() { $this->createBg(); $this->createLine(); $this->createFont(); $this->outPut(); } //获取验证码 publicfunctiongetCode() { returnstrtolower($this->code); } }
