Upgrade Outdated PHP

Need to upgrade a site from PHP 5.3.3 to newest version. Two main issues upgrading:

1) unable to login to admin area of custom built site after 5.6.x and above

2) site doesn't show on 7.x.x and above

Site is currently running 3 platforms: custom-built site, Wordpress and Joomla. We only need help with getting our custom site updated.

The site has several 1,000 pages; however, many are dynamically generated. As far as actual pages, there are probably a few 100 that are unique.

We had somebody who ended up passing away who started updating all the code and said it wasn't difficult just time consuming.

We have no clue how long it will take.

技能: HTML, MySQL, PHP, 网站设计, 数据库编程
