Modernizing PHP one edge case at a time
summary
Walks through exact PHP oddities and the fixes: string "0" is falsy and SimpleXML can make objects evaluate false, GMP boolean-cast bug becomes false in PHP 8.4, comparison rules sometimes force the left operand to be “greater” and array_intersect casts values to strings so arrays collide, string increment spills into numeric semantics prompting a new str_increment helper, range and step edge cases start throwing ValueError in 8.3, disable_functions/classes can cause segfaults, and strict_types applies per file while the engine still uses coercive calls.
