tp6框架升级:使用cmd切换至tp项目后运行以下命令
composer update
php升级到8后,tp6框架中生成验证码报错 Implicit conversion from float 153.60000000000002 to int loses precision
解决方法:
进入vendor/topthink/think-captcha/src/Captcha.php找到writeCurve()方法,
将$px2 = mt_rand($this->imageW / 2, $this->imageW * 0.8);改为 $px2 = mt_rand(intval($this->imageW / 2), intval($this->imageW * 0.8));
protected function writeCurve(): void { $px = $py = 0; // 曲线前部分 $A = mt_rand(1, $this->imageH / 2); // 振幅 $b = mt_rand(intval(-$this->imageH / 4), intval($this->imageH / 4)); // Y轴方向偏移量 $f = mt_rand(intval(-$this->imageH / 4), intval($this->imageH / 4)); // X轴方向偏移量 $T = mt_rand($this->imageH, $this->imageW * 2); // 周期 $w = (2 * M_PI) / $T; $px1 = 0; // 曲线横坐标起始位置 $px2 = mt_rand(intval($this->imageW / 2), intval($this->imageW * 0.8)); // 曲线横坐标结束位置 for ($px = $px1; $px <= $px2; $px = $px + 1) { if (0 != $w) { $py = $A * sin($w * $px + $f) + $b + $this->imageH / 2; // y = Asin(ωx+φ) + b $i = (int) ($this->fontSize / 5); while ($i > 0) { imagesetpixel($this->im, intval($px + $i), intval($py + $i), $this->color); // 这里(while)循环画像素点比imagettftext和imagestring用字体大小一次画出(不用这while循环)性能要好很多 $i--; } } } // 曲线后部分 $A = mt_rand(1, $this->imageH / 2); // 振幅 $f = mt_rand(intval(-$this->imageH / 4), intval($this->imageH / 4)); // X轴方向偏移量 $T = mt_rand($this->imageH, $this->imageW * 2); // 周期 $w = (2 * M_PI) / $T; $b = $py - $A * sin($w * $px + $f) - $this->imageH / 2; $px1 = $px2; $px2 = $this->imageW; for ($px = $px1; $px <= $px2; $px = $px + 1) { if (0 != $w) { $py = $A * sin($w * $px + $f) + $b + $this->imageH / 2; // y = Asin(ωx+φ) + b $i = (int) ($this->fontSize / 5); while ($i > 0) { imagesetpixel($this->im, intval($px + $i), intval($py + $i), $this->color); $i--; } } } }
