1.3. Other Changes to PHP5

Besides the laundry list of OOP changes and the multitude of new functions available, there are also other improvements that have been made in the release of PHP5.

1.3.1. Configuration Changes

In PHP5 there are numerous changes to the php.ini configuration file. These are discussed in greater detail in Chapter 5, but here is a list for your reference:

  • mail.force_extra_parameters

  • register_long_arrays

  • session.hash_function

  • session.hash_bits_per_character

  • zend.ze1_compatibility_mode

With these new directives, you can exert a little more control over your PHP environment, which gives you a little more freedom in coding.

1.3.2. MySQLi

MySQL, as you well know, fits well with PHP in delivering database-driven dynamic websites. Thus, it is the release of the MySQLi (MySQL improved) extension that makes life easier for everyone.

1.3.2.1. Configuration Settings

There are several new MySQLi configuration settings available in php.ini. Here's a brief description:

  • mysqli.max_links: Sets the maximum number of MySQL connections per process.
