+## access policy can be one of
+## .policy_readonly(): All entries are read-only by default.
+##    Individual entries can be set read-write using .readwrite() or .rw()
+## .policy_readwrite(): This is the default and can be omitted.
+##    Individual entries can be set read-only using .readonly() or .ro()
+#sp.ini_protection.policy_readonly();
+
+## sp.ini entries can have the following attributes
+## .key("..."): mandatory ini name.
+## .set("..."): set the initial value. This overrides php.ini.
+##    checks are not performed for this initial value.
+## .min("...") / .max("..."): value must be an integer between .min and .max.
+##    shorthand notation (e.g. 1k = 1024) is allowed
+## .regexp("..."): value must match the regular expression
+## .allow_null(): allow setting a NULL-value
+## .msg("..."): message is shown in logs on rule violation instead of default message
+## .readonly() / .ro() / .readwrite() / .rw(): set entry to read-only or read-write respectively
+##    If no access keyword is provided, the entry inherits the default policy set by sp.ini_protection.policy_*-rules.
+## .drop(): drop request on rule violation for this entry
+## .simulation(): only log rule violation for this entry
