Hello! Most of PHP's symbols are case insensitive. This means extensions that need to do things with function and method names end up lowercasing and hashing the lowercased names, often having to do more memory allocations too. Since case insensitive symbols is language dictated behavior, it makes sense to expose the correctly cased symbols to extensions. In PHP 8.0 (and possibly older, I did not check), the engine is already interning the lowercased name of user defined functions; it's just not made available to extensions.
In my ideal world, we'd actually switch all symbols to be case sensitive. However, that won't be happening for PHP 8 due to BC. So, instead, I propose adding an `.lcname` member (or some other name indicating it's been normalized to the preferred PHP case) to at least zend_op_array and zend_class_entry, but preferably for internal functions too. Note that many internal functions will already be lowercase, so the data can be shared. I could make this change in the main engine, but I strongly suspect it will not play correctly with opcache. -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: https://www.php.net/unsub.php
