国家气象局免费天气预报接口（沈阳）：http://www.weather.com.cn/data/cityinfo/101010100.html
这个接口提供了一个json格式的天气预报数据。
不知道用php怎么得到这个json，在网上找到了以下代码

但其中的httpGetRequest函数是个自定义函数，而且网上并没有放出这个函数的原型！请高手指点！

回复讨论(解决方案)

$url = 'http://www.weather.com.cn/data/cityinfo/101070101.html';$s = file_get_contents($url);print_r(json_decode($s, true));

Array
(
    [weatherinfo] => Array
        (
            [city] => 沈阳
            [cityid] => 101070101
            [temp1] => 10℃
            [temp2] => -2℃
            [weather] => 多云
            [img1] => d1.gif
            [img2] => n1.gif
            [ptime] => 08:00
        )

)

httpGetRequest无需理会，反正目的就是把文本抓下来，只是用了什么手段而已，你完全可以自写
直接获取就按版主给的file_get_contents，想省点流量就用curl或者socket发送压缩请求
先用 file_get_contents 把工作完成了，等有时间学习了curl, socket...再回头优化吧

你贴的代码中 $info 就是你得到的数据

版主就是版主，十分感谢！还有感谢snmr_com的优化建议！

版主的是正确的...

这个接口已经不更新了，获取的数据不对

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages.
