PHP System Upgrade Service Overview

About Updating Your PHP System to the Latest Version

Your website likely contains not only simple HTML pages but also a variety of features such as:

  • Custom-developed systems
    (e.g., database systems for managing website content, product pages, or catalog search tools)
  • Contact forms
    (e.g., automated email forwarding to designated personnel and database storage of form entries)
  • WordPress-based websites

To maintain and operate these systems, it is essential to ensure that the OS and middleware, such as PHP, are updated to the latest versions. The OS and relevant middleware have support lifecycles, after which security updates and other support will no longer be available. To address this, updates to the OS and PHP may be necessary, and in some cases, we may recommend migrating to a new server.


Challenges

Simply switching the PHP version in your server management panel may not be enough in many cases. Especially when there are incompatible changes, modifications to the PHP scripts become essential.
If you consult with us before making any changes, we can confirm compatibility with the target PHP version and provide a detailed estimate for the required modifications.


Current Issues

End of Support for CentOS7 and PHP7

The support period for CentOS7 and PHP7 has already ended. In particular, systems based on PHP 5.x still in use face increasing security risks. For this reason, we strongly recommend upgrading to PHP 8 as soon as possible.

Character Encoding Issues

If your website or database uses Shift_JIS (SJIS), the following issues may arise:

  • Risk of garbled characters
  • Difficulty in supporting multiple languages
  • Compatibility issues
  • Increased operational costs
  • Security concerns
  • Character set limitations

To address these problems, we recommend migrating to modern character encoding, such as UTF-8.


Estimation Process

We will consult with you beforehand regarding the process.

  1. Identification of Target Systems:
    (e.g., websites, web applications, or combinations of systems)
  2. Signing a Non-Disclosure Agreement (NDA):
    To ensure the confidentiality of your information and prevent disclosure to third parties.
  3. Preparation for Testing:
    • Providing a full copy of the target systems
    • Or granting access to your server
      (We will discuss the specifics with you beforehand.)
  4. Testing and Identifying Required Modifications:
    We will create a test environment and outline the necessary adjustments.
  5. Providing an Estimate:
    A detailed quotation will be presented based on the required modifications.
