etrader Posted March 31, 2011 Share Posted March 31, 2011 I have searched a lot but no information about this aspect. I wonder how much heavy is the process of getting parts of a webpage by preg_match? But my question is that which of these options are in favor of lighter CPU process: 1. getting each item between specified tags by a preg_match or 2. First getting the content between <body>, then processing by php tools such as preg_match (again), explode, etc. Thanks for considering this unusual question Link to comment https://forums.phpfreaks.com/topic/232279-question-about-cpu-usage-by-preg_match/ Share on other sites More sharing options...
bh Posted March 31, 2011 Share Posted March 31, 2011 Hi, you should query in the minimal content u can. If your parts in anywhere in the body get the entiry body and run the search loop in it. If those in a div get that div... Anyway regexp is not a fast method. You can use str pos in a loop, with the handy offset paramterer.

etrader Posted March 31, 2011 Author Share Posted March 31, 2011 Thanks for your reply. You mean it is better to query all <div> by individual preg_match as they will work simultaneously? Right? You mean that getting the body into a string and then analyzing is a step by step process which takes time? OK?
