Upgrading from 3.1.2 to 3.1.3¶

Before performing an update you should take your site offline by replacing the index.php file with a static one.

Step 1: Update your CodeIgniter files¶

Replace all files and directories in your system/ directory.

注解

If you have any custom developed files in these directories, please make copies of them first.

Step 2: Remove usage of nice_date() helper (deprecation)¶

The Date Helper function nice_date() is no longer useful since the introduction of PHP's DateTime classes

You can replace it with the following:

DateTime::createFromFormat($input_format, $input_date)->format($desired_output_format);

Thus, nice_date() is now deprecated and scheduled for removal in CodeIgniter 3.2+.

注解

The function is still available, but you're strongly encouraged to remove its usage sooner rather than later.

Step 3: Remove usage of $config['standardize_newlines']¶

The Input Library would optionally replace occurences of rn, r, n in input data with whatever the PHP_EOL value is on your system - if you've set $config['standardize_newlines'] to TRUE in your application/config/config.php.

This functionality is now deprecated and scheduled for removal in CodeIgniter 3.2.+.

注解

The functionality is still available, but you're strongly encouraged to remove its usage sooner rather than later.
