SimpleXMLElement::__construct

(PHP 5 >= 5.0.1, PHP 7)

Creates a new SimpleXMLElement object

final public SimpleXMLElement::__construct ( string $data [, int $options = 0 [, bool $data_is_url = false [, string $ns = "" [, bool $is_prefix = false ]]]] )

Creates a new SimpleXMLElement object.

Parameters:

data

A well-formed XML string or the path or URL to an XML document if data_is_url is TRUE.

options

Optionally used to specify additional Libxml parameters.

data_is_url

By default, data_is_url is FALSE. Use TRUE to specify that data is a path or URL to an XML document instead of string data.

Namespace prefix or URI.

is_prefix

TRUE if ns is a prefix, FALSE if it's a URI; defaults to FALSE.

Returns:

Returns a SimpleXMLElement object representing data.

Exception:

Produces an E_WARNING error message for each error found in the XML data and additionally throws an Exception if the XML data could not be parsed.

Use libxml_use_internal_errors() to suppress all XML errors, and libxml_get_errors() to iterate over them afterwards.

Changelog:

5.2.0

Added the ns and is_prefix parameters.

5.1.2

Added the options and data_is_url parameters.
