This example describes the use of the SimpleXML function in PHP, which allows you to convert XML to an object and share it with everyone for your reference. The specific analysis is as follows:

The SimpleXML function allows you to convert XML to an object, which can be handled by an ordinary property selector or an array iterator, just like any other object. Some of these functions require the latest version of PHP.

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

The code is as follows:

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