Or that there is a separate realpath cache from the regular file stat cache.

The problem was not generated in php7.3.9. 在不使用php函数rmdir删除目录的情况下(如使用命令行删除) 再次使用realpath将不会返回false。在php7.3.9未产生该问题。 Test script: --------------- <?php var_dump(phpversion()); $a = 'eee'; $path = dirname(__FILE__) . DIRECTORY_SEPARATOR . $a; // ------------------ var_dump($path); // ------------------ mkdir($path); var_dump(realpath($path)); // ------------------ passthru('rd "' . $path . '"'); var_dump(realpath($path)); Expected result: ---------------- string(5) "7.3.9" string(24) "E:\phpProject\xlbook\eee" string(24) "E:\phpProject\xlbook\eee" bool(false) Actual result: -------------- string(6) "7.3.10" string(24) "E:\phpProject\xlbook\eee" string(24) "E:\phpProject\xlbook\eee" string(24) "E:\phpProject\xlbook\eee" ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=78634&edit=1
