Hello, I am just starting to use PHP. I have been using PERL for quite some
time. I was wondering if there is any specific FILE LOCKING I need to
implement to keep more than one person from altering a text file at the same
time.
For instance, in PERL, you use the flock command to set up an advisory file
lock. Lets say that if I have a web page with a text based database, and
more than one person wants to write to the file at the same time. In perl,
if you use flock(FILE, 2). This causes person A to wait while person B
writes to the file. flock(FILE, 8) unlocks the file. Then person A is
allowed to write to the file.
Does the perl equivalent of flock happen automatically in PHP?
If not, how do you lock a file?
Is it an advisory lock, or will it cause an error if two people try to
access the same file at the same time for the same purpose (writing).
Thanks,
