// Counter
Function countx ($ file = "count. dat "){
If (file_exists ($ file )){
$ Fp = fopen ($ file, "r ");
$ Numx = fgets ($ fp, 10 );
Fclose ($ fp );
$ Numx ++;
// The above four lines of code can be replaced by an expression: $ numx = file_get_contents ($ file) + 1;
}
Else {
$ Numx = 1 ;}
File_put_contents ($ file, $ numx); // when the file does not exist, this function automatically creates the file and converts the parameter to a string for writing.
Echo $ numx;
/* The entire function body can be replaced by two expressions: file_exists ($ file )? File_put_contents ($ file, file_get_contents ($ file) + 1): file_put_contents ($ file, "1"); readfile ($ file );
*/
}
// Function call
Countx ();
