The linter obviously doesn't catch that. PHPStorm (as a reasonable IDE) also doesn't catch that. In languages PHP tries to follow this is a syntax error. Test script: --------------- $ php -r 'function a($b=true, $c){ var_dump($b,$c); } a(); ' Expected result: ---------------- error: default argument missing for parameter 2 Actual result: -------------- Warning: Missing argument 2 for a(), called in Command line code on line 1 and defined in Command line code on line 1 bool(true) NULL ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=74251&edit=1
