Defines that the file written by the counter is count.txt under the current directory, and then we should test whether the file can be opened
if ($fp = fopen ($countfile, "r+")) = = False) {//Open file in read-write mode, exit if not open
printf ("Open file%s failed!", $countfile);
Exit
}
Else
{
If the file can be opened normally, read the data in the file, assuming it is 1
$count = Fread ($fp, 10);
Read 10-bit data
$count = $count + 1; Fclose ($FP);
Close the current file
$fp = fopen ($countfile, "w+");
Open files in overwrite mode
Fwrite ($fp, $count);
Write new data after add 1
Fclose ($FP);
and close the file } Define output as Image type
$n = 10;
