PHP RFC: Use exceptions by default in SQLite3 extension

• Version: 0.1
• Date: 2022-10-24
• Author: BohwaZ, php at bohwaz dot net
• Status: Implemented
• Implementation: https://github.com/php/php-src/commit/ddd9a08f566d86083d04de320e24f0751a1de759
• First Published at: http://wiki.php.net/rfc/sqlite3_exceptions

The SQLite3 extension is still using PHP warnings by default. PDO is using exceptions, like everyone else.

It's time to move to exceptions.

Progressively deprecate warnings (PHP 8.3), make exceptions the default (9.0) and remove warnings (10.0).

In PHP 8.3:

• Create a new exception class SQLite3Exception, which extends the Exception class
• Remove SQLite3 error code from the error message, and assign it to the exception code
• Make SQLite3::enableExceptions(true) throw SQLite3Exception instead of Exception
• Calling SQLite3::enableExceptions(false) raises E_DEPRECATED
• Default behavior is still to raise warnings (enableExceptions(false))

In PHP 9.0:

• Make SQLite3 throw exceptions of class SQLite3Exception by default, instead of raising warnings
• Calling SQLite3::enableExceptions(false) throws an error
• It's not possible to use warnings anymore.
• Calling SQLite3::enableExceptions(true) raises E_DEPRECATED, to alert that the method will get removed

In PHP 10.0:

• Remove the SQLite3::enableExceptions method

In PHP 8.3:

• Code parsing the error message to get the error code may fail as the error code has been moved to be consistently at the end of the error message string. This is unlikely as the proper way is to use SQLite3::lastErrorCode().
• Code already relying on exceptions will not see a difference, as previously \Exception was thrown, and \SQLite3Exception is a subclass of \Exception

In PHP 9.0:

• Calls to SQLite3::enableExceptions(false) will break
• Code relying on hiding warnings will break

In PHP 10.0:

• Calls to SQLite3::enableExceptions() will fail

PHP 8.3, 9.0, 10.0

None.

Only SQLite3.

None that I can think of.

None.

None.

Everything outside of SQLite3 extension.

Assign SQLite3 error constants to SQLite3Exception class, eg. SQLite3Exception::READONLY, see https://www.sqlite.org/rescode.html
