libxml_disable_entity_loader

Disable the ability to load external entities

&warn.deprecated.function-8-0-0;
&reftitle.description; `bool` `libxml_disable_entity_loader` `bool` `disable`&true;

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.

&reftitle.parameters;

`disable`

- Disable (&true;) or enable (&false;) libxml extensions (such as book.dom, book.xmlwriter and book.xmlreader) to load external entities.

&reftitle.returnvalues;

Returns the previous value.
