We often see that the statistical codes of many websites are displayed in the form of js calls. Let’s take a look at how to implement them.

  1. $countfile = "num.txt";//The file to define the counter is count.txt in the current directory, Then we should test whether the file can be opened
  2. if (($fp = fopen($countfile, "r ")) == false) { //Open the file in read-write mode, exit if it cannot be opened
  3. printf ("Failed to open file %s!",$countfile);
  4. exit;
  5. }else{
  6. $count = fread ($ fp,10); //If the file can be opened normally, read the data in the file, assuming it is 1
  7. $count = $count 1; //Read 10-bit data
  8. fclose ($fp);//Close the current file
  9. $fp = fopen($countfile, "w ");//Open the file in overwrite mode
  10. fwrite ($fp,$count) ;//Write the new data after adding 1
  11. ​​​ fclose ($fp);//And close the file
  12. ​​​ Echo document.write(".$count.")n;// Use javascript to output data
  13. }
  14. ?>
  15. Call the js method in the html file.
