PHP에서 인증코드 클래스 생성 자세히

여기서 인증코드 수업을 작성했습니다. 저는 초보자이므로 건너뛰시기 바랍니다. 사용 방법을 설명하겠습니다. 두 단계만 거치면 됩니다.

1단계:

내가 만든 인증코드 클래스를 다운로드 받으세요. 다운로드 주소: http://files.cnblogs.com/files/xfjpeter/Verify.zip

2단계:

1. 한 단어로 된 인증코드 파일을 생성합니다

<span style="color: #008080;"> 7</span> <span style="color: #008000;">#</span><span style="color: #008000;">初始化的使用可以传四个参数，分别是：验证码图片的长、高，验证码的长度，验证码的类型（验证码的类型需要将bgRand属性设置为false）</span>
<span style="color: #008080;"> 8</span> <span style="color: #800080;">$code</span> = <span style="color: #0000ff;">new</span> Verify(140, 40, 6, 6<span style="color: #000000;">);
</span><span style="color: #008080;"> 9</span> 
<span style="color: #008080;">10</span> <span style="color: #008000;">#</span><span style="color: #008000;">设置验证码图片的长度</span>
<span style="color: #008080;">11</span> <span style="color: #800080;">$code</span> -> width = 200<span style="color: #000000;">;
</span><span style="color: #008080;">12</span> 
<span style="color: #008080;">13</span> <span style="color: #008000;">#</span><span style="color: #008000;">设置验证码图片的高度</span>
<span style="color: #008080;">14</span> <span style="color: #800080;">$code</span> -> height = 60<span style="color: #000000;">;
</span><span style="color: #008080;">15</span> 
<span style="color: #008080;">16</span> <span style="color: #008000;">#</span><span style="color: #008000;">是否随机背景，默认true（随机）</span>
<span style="color: #008080;">17</span> <span style="color: #800080;">$code</span> -> bgRand = <span style="color: #0000ff;">false</span><span style="color: #000000;">;
</span><span style="color: #008080;">18</span> 
<span style="color: #008080;">19</span> <span style="color: #008000;">#</span><span style="color: #008000;">显示验证码</span>
<span style="color: #008080;">20</span> <span style="color: #800080;">$code</span> -> verify();
로그인 후 복사

생성된 이미지 스타일은 그림과 같습니다
