libxml_disable_entity_loader — Disable the ability to load external entities

警告

本函数已自 PHP 8.0.0 起被废弃。强烈建议不要依赖本函数。

说明

libxml_disable_entity_loader(bool $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.

参数

disable

Disable (true) or enable (false) libxml extensions (such as DOM, XMLWriter and XMLReader) to load external entities.

返回值

Returns the previous value.
