Re: String Extension Proposal

I really don't see that the minimal performance improvements on the one special case where you are modifying the string in place warrants the complexity of a string class. I'd bet other overhead will eat away at the performance of even that special case. And the idea that $trimmedStr = $myStr->makeCopy()->trim; is somehow superior to: $trimmedStr = trim($myStr); just seems insane to me. So no, I'd be completely against letting this get anywhere near the core. -Rasmus Jessie Hernandez wrote: > Hello, I've started working on an extension which declares a String > class for PHP.
