设置生成的图片名字 $imagename = "25220_".date("his",time())."_".rand(1111,9999).'.png';
判断是否有逗号 如果有就截取后半部分if (strstr($image,",")){ $image = explode(',',$image); $image = $image[1];}
设置图片保存路径$path = "tmp/signimage/".date("ymd",time());
判断目录是否存在 不存在就创建 并赋予777权限if (!is_dir($path)){ //判断目录是否存在 不存在就创建 mkdir($path,0777,true);}
拼接路径和图片名称 $imagesrc= $path."/". $imagename;
生成图片 返回的是字节数 $r = file_put_contents(root_path ."public/".$imagesrc, base64_decode($image));
判断图片是否生成成功if (!$r) { return json(['data'=>null,"code"=>1,"msg"=>"图片生成失败"]); }else{ return json(['data'=>1,"code"=>0,"msg"=>"图片生成成功"]);}
