We use exceptions for that. > P.S.: For typical MediaWiki use cases, PHP's assert is even faster > than throwing exceptions behind 'if'-guards. That's funny, for me "if" is about 10 times faster than assert() in the non-throwing case. Micro-optimisation in PHP usually revolves around minimising the number of function calls, since a function call is relatively complex and expensive compared to other opcodes. -- Tim Starling _______________________________________________ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
