After you have opened
a file and finished your business you need to close that file.
Don't keep an unnecessary open file on your server as it taking up
resources and can cause mischief!
File
Close Description
In PHP it is not system
critical to close all your files after using them because the server
will close all files after the PHP code finishes execution.
However
the programmer?could make mistakes (i.e. editing a file that
you accidentally forgot to close).
You
should close all files after you
have finished with them because it's a good programming practice.
File Close Function
We
will examine the?example below and
discuss the importance of closing a file.
PHP Code:
$ourFileName
= "testFile.txt"; $ourFileHandle = fopen($ourFileName, 'w') or
die("can't open file"); fclose($ourFileHandle);
The
function fclose requires the file handle that we want to close down.?
In our example above we set our variable "$fileHandle"
equal to the file handle returned by the fopen
function.
After a file has been closed down with fclose
it is impossible to read, write or append to that file unless it is
once more opened up with the fopen function.
