See https://bugs.php.net/bug.php?id=52312#1279034613 and its follow-up https://bugs.php.net/bug.php?id=53263 This is underdocumented. Beyond the source (https://github.com/php/php-src/blob/PHP-7.3.0/main/main.c#L1800), one can find it in the long comments to ini.core and in the realpath_cache_* function comments. The configuration documentation should make the information on the relation of open_basedir to the realpath cache easily accessible. The difference of a disabled realpatch cache can be significant enough to discuss alternative means of isolation to open_basedir. This patch adds two notes: one within the open_basedir option description and one in the performance tuning section listing the realpath_cache options. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=77406&edit=1
