PHP obtains the weather forecast for the current day and 72 hours, and generates the interface-PHP source code.

PHP obtains the weather forecast for the current day and 72 hours, and generates interface parameters:

City, city ID. for details, see the following table. for example, 212 is Chongqing.

Type, output format, json or xml. the default value is json.

Charset, output character encoding, UTF-8, utf8, or gbk. the default value is UTF-8.

Datetype, date output type, unix or other. the default value is unix timestamp.

For example, getweather. php? Type = xml> city = 212

Principle:
Read the HTML code of http://weather.news.qq.com/inc/07_dc'. $ city. '.htm and retrieve the result using regular expressions.
