Hi all,
I want to create an if statement like:
if (-e $file) {
for($i = 0; $i < 10; $i++) {
sleep(1);
}
unlink $file;
}
Please tell me what will happen if in this period of time (10 seconds)
another page visitor, or program will delete $file.
Will this script try to delete a non existent $file?
Will the script check the if statement for each function under it, so it
will see that there is no $file, or I should use:
unlink $file if -e $file;
Thanks.
