In PHP programming, when you finish using a file, you must close it in time. This is a good habit.

php function or method to close a file

To close a file in php, you need to use the function fclose.

The following is an example of closing a file for reference.

Code:

<?php
//关闭文件
$ourFileName = "testFile.txt";
$ourFileHandle = fopen($ourFileName, 'w') or die("can't open file");
fclose($ourFileHandle);
//by bbs.it-home.org
?>

Code description: The fclose function requires a file handle to be closed. In the above example, we set the variable "$ourFileHandle" to the file handle returned by the fopen function.

After performing the above operation, the opened file testfile.txt will be closed. Any subsequent operations such as reading or appending the file content will be invalid. The above operation can only continue when the access file is opened again.
