今天晚上彻夜加班,碰巧看到两个网页。我对php所知甚少。anyway, 看看有没有更方便的办法。

Is it so difficult. :)
Anyway, tonight I learnt the jargon for this script. Captcha image validation. Widely used. But I would assume there are image recognition scripts or codes already to crack simple Captcha. Here is not google, luckily. :) - Re: PHP script to block automated postposted on 11/29/2007

能不能把code弄成变形的,有些spam有图形识别能力。
如果花太多时间就算了。 - Re: PHP script to block automated postposted on 11/29/2007
It generates random number everytime...
I use English upper case, lower case as well as number combinations, No chinese, for the sake of easily typing.

Don't use this - it's too advanced for this small web server. Only Google needs that.
The key requriement to this function is simple-to-use for us, rather than scare-off spammers once-for-all.
I would reckon a simple image with random numbers in it would be sufficient. Noise pixels or not doesn't matter. It's quick to render to client, and easy to see for the people. Performance and Usability always come first. :)
And you don't want to kill off the emeny once-for-all - you only need the easiest way with minimum cost as a start. Then increase your power step by step as the devil grows. :) - Re: PHP script to block automated postposted on 11/30/2007
变形的图形也写出来了,不好认,还是不变吧
大家说说

先不变吧,code 预留下,以后需要再用。

Oh my goodness. By a simple glance of that I would simply forget what I am going to see in the postings. A good way to kill me off. Where do you want us to concentrate on? :)
Better not use that. Agree with LM this time.
