Source code outcome What does that mean? A simple counter source code

$memo _file= "Phpcount/vst.txt";
if ($phpxcount <> $REMOTE _addr) {
$visits = File ($memo _file);
$number _of_last_visit = $visits [0];
$number _of_new_visit = + + $number _of_last_visit;
$fp = fopen ($memo _file, "w");
$FW = fwrite ($fp, $number _of_new_visit);
Fclose ($FP);
$len _str = strlen ($number _of_new_visit);
for ($i = (0); $i < $len _str; $i + +) {
$numbers _exploded = substr ($number _of_new_visit, $i, 1);
$output _str = $output _str. "";
}
}else{
$visits = File ($memo _file);
$number _of_last_visit = $visits [0];
$number _of_new_visit = $number _of_last_visit;
$fp = fopen ($memo _file, "w");
$FW = fwrite ($fp, $number _of_new_visit);
Fclose ($FP);
$len _str = strlen ($number _of_new_visit);
for ($i = (0); $i < $len _str; $i + +) {
$numbers _exploded = substr ($number _of_new_visit, $i, 1);
$output _str = $output _str. "";
}
}
echo $output _str;
?>

The above describes the source code ending what the meaning of a simple counter source code, including the source code ending what the meaning of the content, I hope the PHP tutorial interested in a friend helpful.
