Check if a text file exists and if not create it

[Dalziel]

I want to use a PHP script to check whether a file exists or not and if not to create it.

Example that is not written in PHP but shows what I want to do:

if (main.txt exists)
{
do nothing
}
else
{
create main.txt with just one character inserted into it, a 0.
}

clearstatcache();
if(!file_exists("your_filename_here"))
{
$fp = fopen("your_filename_here","w");
fwrite($fp,"0");
fclose($fp);
}


Don't forget to add error checking.

Doesn't fopen automatically create a file if the named file doesn't exist?

Yes, but it also truncate file. It may be not what Dalziel wants.

Yes but it's being used for a hit counter, if I left it for fopen to create it, the first time the page was loaded an error would be displayed.
