Hello.
I am trying to put one counter in my php with the next code:
<?php

$hitfile = "/admin/contador.txt";
if (!file_exists($hitfile)) {
$file = fopen($hitfile,"r+");
$hits = fread($file,filesize($hitfile));
fclose ($file);
}
else {
$hits = 0;
}
$file = fopen($hitfile,"w+");
fwrite ($file, ++$hits);
fclose ($file);
?>

but when i try to see the php page appears this error:

Warning: fopen(/admin/contador.txt) [function.fopen]: failed to create
stream: No such file or directory in /home/usuairo/pagina.php on line 9

Warning: filesize() [function.filesize]: Stat failed for /admin/contador.txt
