本文實例講述了php實現(xiàn)與python進行socket通信的方法。分享給大家供大家參考，具體如下：
設(shè)計目的
通過前端頁面發(fā)起請求交給php，php創(chuàng)建socket請求交給Python腳本，然后執(zhí)行完畢之后，返回給前端。

# Now, you can use telnet to test it, the command is "telnet 127.0.0.1 9011"
# You also can use web broswer to test, input the address of "http://127.0.0.1:9011" and press Enter button
# Enjoy it....
