php mysql与xml数据相互转换程序
很多时间我们要把数据保存到其它地方,如保存到xml或又想把xml数据保存到mysql数据库,下面我们就提供了一款php mysql与xml数据相互转换程序哦。
先来看看调用方法
<?php
$xml = new MySQL2XML(array(
'host' => 'localhost',
'username' => 'root',
'password' => '',
'database' => 'mysql'
));
$xml->setTables(array(
'wp_term_relationships',
'wp_terms'
)); //设置备份的表
$xml->setSaveFolder('datas/'); //保存备份文件的文件夹
$xml->toXML(); //备份开始下面是这个互相转换程序的类型文件
<?php
class MySQL2XML {
protected $conn;
protected $result;
protected $tables;
protected $saveFolder = 'datas/';
public function __construct($config = NULL) {
if ($config !== NULL && is_array($config)) {
$this->connect($config);
}
}
public function connect($config) {
$this->conn = mysql_connect($config['host'], $config['username'], $config['password']);
if ($this->conn) {
mysql_select_db($config['database']);
return true;
}
return false;
}
public function setSaveFolder($folder) {
if (is_dir($folder)) {
$this->saveFolder = rtrim(str_replace("\\", "/", $folder) , '/');
return true;
}
return false;
}
public function setTables($tables) {
if (is_array($tables)) {
$this->tables = $tables;
return true;
}
return false;
}
public function query($query) {
if (!isset($query) || trim($query) == '') return false;
$this->result = mysql_query($query);
if ($this->result) return true;
return false;
}
public function toXML() {
if (!isset($this->tables)) return false;
foreach ($this->tables as $table) {
$file = $this->saveFolder . $table . '.xml';
$fp = @fopen($file, 'w');
if (!$fp) exit('Can not write file');
fwrite($fp, $this->tableToXML($table));
fclose($fp);
unset($fp);
}
return true;
}
public function tableToXML($table) {
header("content-type:text/xml;charset=utf-8");
$xml = "<?xml version=\"1.0\" encoding=\"utf-8\" ?>\n<datas>\n";
$fields = $this->getFields($table);
$datas = $this->getDatas($table);
$cdata = array();
foreach ($datas as $data) {
foreach ($data as $key => $value) $cdata[$key][] = $value;
}
foreach ($fields as $element) {
$xml.= "\t<fields name=\"{
$element['Field']
}
" type=" {
$element['Type']
}
" null=" {
$element['Null']
}
" key=" {
$element['Key']
}
" default=" {
$element['Default']
}
" extra=" {
$element['Extra']
}
\">\n";
foreach ($cdata[$element['Field']] as $value) {
$xml.= "\t\t<data>{$value}</data>\n";
}
$xml.= "\t</fields>\n";
}
$xml.= '</datas>';
return $xml;
}
protected function getFields($table) {
$query = "SHOW FIELDS FROM {$table}";
$this->query($query);
return $this->fetchAll();
}
protected function getDatas($table) {
$query = "SELECT * FROM {$table}";
$this->query($query);
return $this->fetchAll();
}
protected function fetch() {
if (is_resource($this->result)) {
return mysql_fetch_assoc($this->result);
}
return false;
}
protected function fetchAll() {
if (is_resource($this->result)) {
$return = array();
$row = NULL;
while ($row = mysql_fetch_assoc($this->result)) {
$return[] = $row;
}
return $return;
}
return false;
}
