The application example _php technique of Php+xml programming simplexml

This paper illustrates the application of the simplexml of Php+xml programming. Share to everyone for your reference. Specifically as follows:

SimpleXML's core idea: manipulating an XML file in an object-oriented manner, which converts all elements of an XML file into objects.

XML Document: Words.xml

Copy Code code as follows:

<?xml version= "1.0" encoding= "Utf-8"?>
<words>
<word>
<en>boy</en>
<ch> Boy </ch>
</word>
<word>
<en>girl</en>
<ch> Girls </ch>
</word>
<word>
<en>teacher</en>
<ch> Teacher </ch>
</word>
<word>
<en>beauty</en>
<ch> Beauty </ch>
</word>
</words>

SimpleXML Use examples:

Copy Code code as follows:

<?php
echo "<pre>";
$words = simplexml_load_file ("Words.xml")//Returns an array object that can be viewed with print_r () or Var_dump ()
Var_dump ($words);
?>

Read content:

Copy Code code as follows:

<?php
echo "<pre>";
$words = simplexml_load_file ("Words.xml")//Returns an array object that can be viewed with print_r () or Var_dump ()
Echo $words->word[2];
foreach ($words->word as $row) {//$row or an object
Print_r ($row);
echo $row->ch. " }
?>

The second section of the code output results:

Copy Code code as follows:

SimpleXMLElement Object
(
[En] => boy
[CH] => Boy
)
Boy
SimpleXMLElement Object
(
[En] => girl
[CH] => Girl
)
Girl
SimpleXMLElement Object
(
[En] => teacher
[CH] => teacher
)
Teacher

I hope this article will help you with the Php+xml program design.
