问题
I am sort of stuck. My goal is to extract data from a website that has several hundred pages. Its a sports website and i have to extract the team names and other relevant data. So far i have been successful doing it. I ran the loop for 6-7 pages and its works perfectly well. but when i change the loop to about month(25), it retrieves incomplete data.
For instance if the destination date is 25 October, it may stop randomly at 10-12 October.
I am using phpQuery and my internet connection is 1MB.
Kindly guide me in this matter, Thank You.
