Description:

This issue is to officially track and implement support for PHP 8.4 across the php-imap2 library.

With PHP 8.4 introducing several changes (deprecations, strictness improvements, internal API adjustments), it's crucial to make sure php-imap2 stays compatible and stable moving forward.

---

Checklist:

• Review all core files for potential incompatibilities
• Update deprecated PHP functions or syntax
• Validate compatibility with new PHP 8.4 INI defaults and behavior
• Test under PHP 8.4 using the full test suite (if available)
• Add PHP 8.4 to CI matrix (GitHub Actions / Travis / etc.)
• Update composer.json to allow php: ^8.4
• Tag a new release (v2.x.x or v3.0.0 depending on BC impact)

---

Context:

• PHP 8.4 RFCs Overview
• Focus on:
  • Potential changes to imap_* functions under PHP 8.4
  • Stricter type handling in class constructors and method parameters
  • New warnings or deprecations that could affect this library

---

Note:

If you’re already running PHP 8.4 and encounter any issues, please comment below with:

• PHP version output (php -v)
• Failing method / class
• Relevant error message or stack trace

Let’s keep this library future-proof and blazing fast! 🚀🐘💙

I have found a memory leak :
Allowed memory size of 268435456 bytes exhausted (tried to allocate 262144 bytes) in vendor/javanile/php-imap2/bootstrap.php on line 331

And nothing regarding a specificity in 8.4

I assume this project is dead now, since there is a €5000 goal for the PHP 8.4 work to be started which has only reached 10%, there have been no code updates for four years (other than the fundraiser last year), and PHP 8.4 is no longer the newest version?

A lot has changed since I first started this project and the initial campaign.

This project was born to address a problem that, at the time, didn’t seem to be properly handled. I’ve always tried to find the motivation to keep it going, but over time that became harder.

That said, the project is not “dead”: it remains open, and anyone is free to fork it, update it, and take it further if they have the time and need for it.

One of the main factors that slowed me down was the uncertainty around Roundcube. I never really managed to get a clear answer about whether I could safely reuse and integrate parts of their code into this project (even with proper credits). That lack of clarity made it difficult to move forward with confidence.

In any case, what this project really needs is a mature IMAP client, and that remains a key challenge.

Thanks for your interest and for bringing this up.
