是否可以在PHP的date（）函数中重新定义一些预设格式？

Question

We've run into an unexpected issue using PHP's date("c") formatting in PHP 5.3.

The format returns a value that is hostile to the datetime column type in MySQL 5.7 and above.

We never realized we were vulnerable to this issue until we attempted to upgrade our MySQL install and we started getting errors from the DB.

Our use of date("c") is nearly ubiquitous in our PHP code, so we face a dilemma and my team is looking to me to solve.

I want to redefine how PHP returns date("c") permanently for all scripts that run on my servers. Is there a way to branch the function to redefine this preset?

Thanks in advance for your suggestions.

As mentioned in the other comments, PHP 5.3 is extremely out of date and should no longer be used . As of the time of writing this comment, support ended almost 5 years ago.

I would suggest upgrading your PHP version as soon as possible to reduce the chances of security issues.

In regards to your issue, I think rather than re-defining the constant (which isn't possible without a custom PHP build) it would make more sense to do a regex find & replace across your codebase.

There are only a few functions that accept date format string, so it shouldn't be too hard to replace them automatically.
