libxml_disable_entity_loader — Disable the ability to load external entities
This function has been DEPRECATED as of PHP 8.0.0. Relying on this function is highly discouraged.
$disable = true): bool
   Disable/enable the ability to load external entities.
   Note that disabling the loading of external entities may cause general issues
   with loading XML documents. However, as of libxml 2.9.0 entity substitution
   is disabled by default, so there is no need to disable the loading of external
   entities,
   unless there is the need to resolve internal entity references with LIBXML_NOENT.
   Generally, it is preferable to use libxml_set_external_entity_loader()
   to suppress loading of external entities.
  
Returns the previous value.
LIBXML_NOENT constant
