PHP counter program: solves all possible problems. The general counter program executes the external program function exec (), but many host spaces (including charged) refuse this dangerous operation. We have to use fread (), fwrite () and other file read/write functions. Generally, the counter program executes the external program function exec (), but there are
In the multi-threaded environment to count, you need to ensure that the consistency of the count variables and thread safety to ensure that the count is correct in multi-threaded environment.The atomic count is the feature that provides this requirement, which guarantees that the count operation will never be interrupted by any other practice or event when it is completed, and the following is an atomic counter for pthreadsCons: When you use locks to
Before House Orso near saw a lot of such examples, each method is complex, see the following example to implement a graphical counter. Use in Web pages

PHP is now a popular server-side scripting language, it's very powerful, you can use it to do almost anything. Without the need for complex variables and code, you can make beautiful counters very quickly. Next, let's do it step-by-step.
In fact, the principle of the counter everyone knows, first of all, determine a record file, such as Counter.txt or Counter.log, each time you visit this page, add 1 to this file, and then show the results.

Step 1: Create a counter (the simplest digital counter, not an image-based counter ):
Set fsFilesys = CreateObject ("Scripting. FileSystemObject ")
Set myText = fsFilesys. OpenTextFile (Server. MapPath ("/count") "\ count.txt") count = myText. ReadLine
'Read the Count value stored in count.txt. You can write 8771990 first.
My Text. close
Count = count + 1

Combining input streams then using scan -to-track the results are a common scenario when coding with streams.

The list of nested layers is essentially a combination of single-layer lists. The complex hierarchy is made up of a two-tier hierarchy of parent-child relationships. As long as each of the most basic parent-child relationship level is not messy, the composition of the more complex structure will not be chaotic. The point is: 1, the relationship between the subordinate must be clear, father-son relationship is a father-son relationship, brotherhood is a brotherly relationship. 2, the style of the

Counters are essential to websites. Don't underestimate them. every time the webmaster looks at the rapid growth of numbers on a small counter, it feels really good. In the past, we used cgi and asp to write counters. There are many articles in this regard. here, we will use the popular jsp technology to demonstrate how to make a counter. Here we use two files: test. js? 7.1.2 counters
