I plan to upgrade my version of PHP 4 to PHP 5 on my FreeBSD box. Should I be concerned with my existing PHP scripts? |

| Well, I certainly wouldn’t be concerned too much as I have updated all my web hosting servers to PHP 5 with absolutely no complaints. If you go to the Zend website, they have a page which lists the differences between the two versions of PHP – which isn’t a lot to be honest.
If you have clients running on your web servers then you can run the two versions in parallel. You will have to set up your Apache (or whatever web server you’re using) to handle different file extensions with corresponding versions of PHP. For example, files with .PHP and .PHP4 will still be parsed and handled by PHP 4, while .PHP5 extensions can be parsed by PHP 5. It’s really simple to set up if you compiled your PHP as a module add-on.
Overall, I would suggest that you move entirely over to PHP 5 soon. If I remember correctly, from PHP 4.3.1 onwards, no major updates will be made only minor security updates. All major developments will be focused on the version 5 branch.
