With the first get_html () to achieve a simple data acquisition, because it is a implementation of data acquisition of the transmission time will be all the total length of the page download, a page assuming 1 seconds, then 10 pages is 10 seconds. Fortunately Curl also provides the function of parallel processing.

Using the first get_html () to achieve a simple data acquisition, because it is a single execution to collect data transfer time will be the total length of all page downloads, a page assumes 1 seconds, then 10 pages is 10 seconds. Fortunately, Curl also provides the capability of parallel processing.
To write a parallel collection of functions, first of all to

0 Introduction the The country has proposed a "Smart grid" program and has developed a timetable for building a "strong smart grid". "Smart Grid" will achieve the "power flow, information flow, business flow," the integration of a high degree of integration. Intelligent substation is an important foundation and support of strong smart grid, it is in the center of the smart grid hub position. On the receiving of high-voltage power grid input, the next to complete the substation and the u
