rspec/rules/S3337/php/rule.adoc

``++enable_dl++`` is on by default and allows ``++open_basedir++`` restrictions, which limit the files a script can access, to be ignored. For that reason, it's a dangerous option and should be explicitly turned off.


This rule raises an issue when ``++enable_dl++`` is not explicitly set to 0 in _php.ini_.

== Noncompliant Code Example
