Graph Counter Example
Hello, you are the first guest
|
Count. php file
| The Code is as follows: |
|
Header ("Content-type: image/gif ");
// The http header, telling the browser that this is a GIF Image $ Countfile = "num.txt ";
// Define that the file written by the counter is count.txt under the current directory. Then, we should test whether the file can be opened.
If ($ fp = fopen ($ countfile, "r +") = false) {// open the file in read/write mode. if the file cannot be opened, exit.
Printf ("opening file % s failed! ", $ Countfile );
Exit;
}
Else
{
// If the file can be opened normally, the data in the file will be read, assuming 1
$ Count = fread ($ fp, 10 );
// Read 10-Bit Data
$ Count = $ count + 1; Fclose ($ fp );
// Close the current file
$ Fp = fopen ($ countfile, "w + ");
// Open the file in overwrite Mode
Fwrite ($ fp, $ count );
// Write new data after 1
Fclose ($ fp );
// Close the file } // Define output as image type
$ N = 10;
// Variable $ n is the number of digits displayed |
