DOMDocument generation and parsing XML format data in PHP

Array

The code is as follows	Copy Code
$arr [] = Array ( ' Name ' => $row [' name '], ' Sex ' => $row [' Sex '], ' Age ' => $row [' age '] );

Generate PHP

The code is as follows

Copy Code

$doc = new DOMDocument (' 1.0 ', ' utf-8 '); Declaring versions and encodings $doc->formatoutput = true; $r = $doc->createelement ("root"); $doc->appendchild ($R); foreach ($arr as $dat) { $b = $doc->createelement ("data"); $name = $doc->createelement ("name"); $name->appendchild ($doc->createtextnode ($dat [' name ')]); $b->appendchild ($name); $sex = $doc->createelement ("sex"); $sex->appendchild ($doc->createtextnode ($dat [' sex '])); $b->appendchild ($sex); $age = $doc->createelement ("Age"); $age->appendchild ($doc->createtextnode ($dat [' age '])); $b->appendchild ($age); $r->appendchild ($b); } echo $doc->savexml ();

This generates an XML file.

Parsing XML files is also very simple.

code is as follows

copy code

" Header ("content-type:text/html; Charset=utf-8 "); $url = "createxml.php"; $reader = new XMLReader ();//Instantiate XMLReader $reader->open ($url);//Get XML $i =1; while ($reader->read ()) { if ($reader->nodetype = = Xmlreader::text) {//Judge node type $m = $i%3; if ($m ==1) $name = $reader->value;//Read node value If ($m ==2) $sex = $reader->value; If ($m ==0) { $age = $reader->value; $arr [] = array ( ' name ' => $name, ' sex ' => $sex, ' age ' => $age ); } $i + +; } } //print_r ($arr);
