<?php
Creating XML objects
$xmldoc = new DOMDocument ();
$xmldoc->load ("Words.xml");
Inquire
if (!empty ($_post[' Sub ')) {
$en _word = $_post[' Enword '];
$word = $xmldoc->getelementsbytagname ("en");
For ($i =0 $i < $word->length; $i + +) {
if ($en _word== $word->item ($i)->nodevalue) {
$CN _word = $xmldoc->getelementsbytagname ("ch")->item ($i)->nodevalue;
Break
}else{
$CN _word = "The word you entered is not found";
}
}
echo $CN _word;
}
Add entry
if (!empty ($_post[' Add ')) {
$en _word = $_post[' En_word '];
$ch _word = $_post[' Ch_word '];
Get root node
$words = $xmldoc->getelementsbytagname ("words")->item (0);
Add elements, adding content
$new _word = $xmldoc->createelement ("word");
$new _word_en = $xmldoc->createelement ("en");
$new _word_en->nodevalue = $en _word;
$new _word_ch = $xmldoc->createelement ("ch");
$new _word_ch->nodevalue = $ch _word;
Elements, meaning that the child elements are connected to the parent element
$new _word->appendchild ($new _word_en);
$new _word->appendchild ($new _word_ch);
$words->appendchild ($new _word);
Save
$xmldoc->save ("Words.xml");
}
?>
