<?php // int isn't a reserved word, right? // So this should work fine! const test = 7; // Let's try using it! var_dump(test); /* Wait, what? A parse error? Why, you might ask? (int) is a special case in the lexer. Turns out that casts are lexed specially. Why? Probably to stop the type names being reserved words. That worked out spectacularly, didn't it. This has been around since at least PHP 3. */
