This article describes how to use the advanced interface to develop the function of the parameter QR code on the public platform. First, the scene two-dimensional code In order to meet the needs of User channel promotion analysis, the public platform provides an interface to generate two-dimensional code with parameters. The interface can be used to obtain a number of two-dimensional code with different scene values, after the user scans, the public number can receive the event push. There are

Set PHP tutorial. ini Script Timeout method There are two sets ofMethod One, set inside the php.ini max_execution_time = 1800; Currently the above method can take advantage of ini_set ("Options", "value"),Ini_set (' max_execution_time ', ' 180 '); Method two uses the PHP page to add Set_time_limit (), If you add Set_time_limit (100) at the beginning of the PHP document, it represents a 100-second timeout. http://www.bkjia.com/PHPjc/632293.ht

PHP's performance has been improving. However, if the use of inappropriate, or a inattention, still may be stepping on the internal implementation of PHP hole. I ran into a performance problem a few days ago. The thing is this, a colleague feedback our interface each return takes 5 seconds, we review the code together, "surprise" discovery actually in the loop (about 900 times) called a read cache operation, and this cache key does not change, so we put this code to the outside of the loop , re

the tour. For the server side, visitors can be known, visitors to browse the page is also known, but how to know when to go? Because the HTTP protocol is stateless, it cannot be known. It is common practice to note the last time a visitor browses a site page. If the visitor does not have a new action at a specific time, then it can be assumed that he is gone. According to the above idea, I think it is better to use the database, because the database is more efficient than other methods such as
