simplexml_load_file — Interprets an XML file into an object
$filename,$class_name = SimpleXMLElement::class,$options = 0,$namespace_or_prefix = "",$is_prefix = falseConvert the well-formed XML document in the given file to an object.
filename
Path to the XML file
class_name
You may use this optional parameter so that simplexml_load_file() will return an object of the specified class. That class should extend the SimpleXMLElement class.
options
Since Libxml 2.6.0, you may also use the
options parameter to specify additional Libxml parameters.
namespace_or_prefix
Namespace prefix or URI.
is_prefix
true if namespace_or_prefix is a prefix, false if it's a URI;
defaults to false.
Returns an object of class SimpleXMLElement with
properties containing the data held within the XML document, 或者在失败时返回 false.
Produces an E_WARNING error message for each error
found in the XML data.
Use libxml_use_internal_errors() to suppress all XML errors, and libxml_get_errors() to iterate over them afterwards.
示例 #1 Interpret an XML document
<?php
// The file test.xml contains an XML document with a root element
// and at least an element /[root]/title.
if (file_exists('test.xml')) {
$xml = simplexml_load_file('test.xml');
print_r($xml);
} else {
exit('Failed to open test.xml.');
}
?>
This script will display, on success:
SimpleXMLElement Object ( [title] => Example Title ... )
At this point, you can go about using $xml->title
and any other elements.
