| This change to the semantics of non-strict comparisons is backwards incompatible. Worse, it constitutes a silent change in core language semantics. Code that worked one way in PHP 7.4 will work differently in PHP 8.0. Use of static analysis to detect cases that may be affected is likely to yield many false positives. | This change to the semantics of non-strict comparisons is backwards incompatible.
