Попередньо визначені константи

Константи, описані нижче — визначені цим розширенням, тож доступні, коли розширення скомпільовано як частина PHP або динамічно підключене під час виконання.

LIBXML_BIGLINES (int)

Allows line numbers greater than 65535 to be reported correctly.

Зауваження:

Only available as of PHP 7.0.0 with Libxml >= 2.9.0

LIBXML_COMPACT (int)

Activate small nodes allocation optimization. This may speed up your application without needing to change the code.

Зауваження:

Only available in Libxml >= 2.6.21

LIBXML_DTDATTR (int)

Default DTD attributes

Застереження

Enabling loading of DTD attributes will enable fetching of external entities. The LIBXML_NO_XXE constant can be used to prevent this (only available in Libxml >= 2.13.0, as of PHP 8.4.0).

LIBXML_DTDLOAD (int)

Load the external subset

Застереження

Enabling loading of external subsets will enable fetching of external entities. The LIBXML_NO_XXE constant can be used to prevent this (only available in Libxml >= 2.13.0, as of PHP 8.4.0).

LIBXML_DTDVALID (int)

Validate with the DTD

Застереження

Enabling validating the DTD may facilitate XML External Entity (XXE) attacks. The LIBXML_NO_XXE constant can be used to prevent this (only available in Libxml >= 2.13.0, as of PHP 8.4.0).

LIBXML_HTML_NOIMPLIED (int)

Sets HTML_PARSE_NOIMPLIED flag, which turns off the automatic adding of implied html/body... elements.

Зауваження:

Only available in Libxml >= 2.7.7 (as of PHP >= 5.4.0)

LIBXML_HTML_NODEFDTD (int)

Sets HTML_PARSE_NODEFDTD flag, which prevents a default doctype being added when one is not found.

Зауваження:

Only available in Libxml >= 2.7.8 (as of PHP >= 5.4.0)

LIBXML_LOADED_VERSION (string)

Version of libxml's core parser module.

LIBXML_NOBLANKS (int)

Remove blank nodes

LIBXML_NOCDATA (int)

Merge CDATA as text nodes

LIBXML_NOEMPTYTAG (int)

Expand empty tags (e.g. <br/> to <br></br>)

Зауваження:

This option is currently just available in the DOMDocument::save and DOMDocument::saveXML functions.

LIBXML_NOENT (int)

Substitute entities

Застереження

Enabling entity substitution may facilitate XML External Entity (XXE) attacks.

LIBXML_NOERROR (int)

Suppress error reports

LIBXML_NONET (int)

Disable network access when loading documents

LIBXML_NOWARNING (int)

Suppress warning reports

LIBXML_NOXMLDECL (int)

Drop the XML declaration when saving a document

Зауваження:

Only available in Libxml >= 2.6.21

LIBXML_NO_XXE (int)

Disables XML External Entities (XXE) when performing entity substitution

Зауваження:

Only available in Libxml >= 2.13.0, as of PHP 8.4.0

LIBXML_NSCLEAN (int)

Remove redundant namespace declarations

LIBXML_PARSEHUGE (int)

Sets XML_PARSE_HUGE flag, which increases some hardcoded limits from the parser. This affects limits like maximum depth of a document or the entity recursion, as well as limits of the size of text nodes.

Застереження

Because this increases the hardcoded limits, it should only be used with trusted data. Raising the depth limit on untrusted input can lead to excessive resource consumption, such as a stack overflow while processing a deeply nested document.

Зауваження:

Only available in Libxml >= 2.7.0 (as of PHP >= 5.3.2 and PHP >= 5.2.12)

LIBXML_PEDANTIC (int)

Sets XML_PARSE_PEDANTIC flag, which enables pedantic error reporting.
