simplexml function Usage Analysis _php techniques in PHP

This example describes the use of the SimpleXML function in PHP, which allows you to transform XML into objects and share them for your reference. The specific analysis is as follows:

The SimpleXML function allows you to convert XML to an object, and you can work with the object as you would any other object by using a normal property selector or an array iterator. Some of these functions require the latest PHP version.

Installation: The SimpleXML function is part of the PHP core and can be used without installation, and the code is as follows:

Copy Code code as follows:

<?php
Return all content as an object
$lib = simplexml_load_file ("Cet4.xml");
Returns the acquired item node as an array
$items = $lib->item;
$wordsLength = sqlserver/42852.htm Target=_blank >count ($items);
Gets the next node value of all nodes
for ($i =0; $i < $wordsLength; $i + +) {
$word = $items [$i];
echo $word->word. '-----' $word->trans. '-----'. $word->phonetic. ' <br/> ';
}
SimpleXML combining XPath is omnipotent
$words = $lib->xpath ("//word");
Methods to get Properties
echo $words [0][' Add ']. ' <br/> ';
echo $items [0][' PP '];
?>
