PHP Bug Type: *General Issues
Bug description: mutliple users cause write one but not another
Description:
------------
NOT sure if this is a bug or program issue. If two people acess the file
at the same time, would php write both of their information to the file or
one will write to the file and the other doesn't not. With the code below,
on the RequestLog.txt file, both of them on that file but only one on the
TimeRequested.csv file. Why is this happened? Or this happen because
someone is open the file (TimeRequested) while the other write to the
file. Any help would be appreciate.
Reproduce code:
---------------
$flog = fopen("RequestLog.txt","a");
fwrite($flog, $name);
fwrite($flog, " submitted on ");
fwrite($flog, $day);
fwrite($flog, " at ");
fwrite($flog, $time);
fwrite($flog, "\n");
fclose($flog);
if(file_exists("TimeRequested.csv"))
{
writeToFile();
}
else
{
writeToFileHeader();
}
Expected result:
----------------
All information of the two people access at the same time should be in the
TimeRequested.csv file
Actual result:
--------------
Only one information write to the file.
