我被要求解析一个存储为XML文件的简单文件，然后将数据保存到mysql中。使用php解析XML并将其保存到mysql
但是我完全不知道该怎么办，在网上查看后，所有给出的例子似乎对我的问题或者是不正确的解决方案来说太复杂了。 XML文件看起来像这样
games_scores.xml
<gesmes:Letter>
<gesmes:subject>Reference Scores</gesmes:subject>
-
<gesmes:Sender>
<gesmes:name>Game Information Scores</gesmes:name>
</gesmes:Sender>
-
<Cube>
-
<Cube time="2010-10-13">
<Cube scores="GameA1" value="1.5803"/>
<Cube scores="GameA2" value="21.35"/>
............etc
<Cube scores="GameA15" value="135"/>
</Cube>
</Cube>
</gesmes:Letter>
的话，我必须保存它到mysql现有的，这是
CREATE TABLE IF NOT EXISTS `scrore_table` (
`scrore_id` int(11) NOT NULL auto_increment,
`scrore_title` varchar(32) collate utf8_bin NOT NULL default '',
`scores` varchar(15) collate utf8_bin NOT NULL default '',
`decimal_place` char(1) collate utf8_bin NOT NULL,
`value` float(15,8) NOT NULL,
`date_updated` datetime NOT NULL default '0000-00-00 00:00:00',
PRIMARY KEY (`currency_id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1; ;
INSERT INTO `scrore_table` (`scrore_id`, `scrore_title`, `scores`, `decimal_place`, `value`, `date_updated`) VALUES
(1, 'Game Class A0', 'GameA0', '2', 1.00000000, '2010-04-06 22:00:54'),
(2, 'Game Class A1', 'GameA1', '2', 1.58030000, '2010-04-06 22:00:54'),
(3, 'Game Class A2', 'GameA2', '2', 21.3503000, '2010-04-06 22:00:54'),
..............................etc
(15, 'Game Class A15', 'GameA15', '2', 135, '2010-04-06 22:00:54');
方向看起来这个问题，我按照有PHP脚本：
<?php
class Scores_Converter {
var $xml_file = "http://192.168.1.112/gamescores/games_scores.xml";
var $mysql_host, $mysql_user, $mysql_pass, $mysql_db, $mysql_table;
var $scores_values = array();
//Load convertion scores
function Scores_Converter($host,$user,$pass,$db,$tb) {
$this->mysql_host = $host;
$this->mysql_user = $user;
$this->mysql_pass = $pass;
$this->mysql_db = $db;
$this->mysql_table = $tb;
$this->checkLastUpdated();
$conn = mysql_connect($this->mysql_host,$this->mysql_user,$this->mysql_pass);
$rs = mysql_select_db($this->mysql_db,$conn);
$sql = "SELECT * FROM ".$this->mysql_table;
$rs = mysql_query($sql,$conn);
while($row = mysql_fetch_array($rs)) {
$this->scores_values[$row['scores']] = $row['value'];
}
}
/* Perform the actual conversion, defaults to 1.00 GameA1 to GameA3 */
function convert($amount=1,$from="GameA1",$to="GameA3",$decimals=2) { return(number_format(($amount/$this->scores_values[$from])*$this->scores_values[$to],$decimals));
}
/* Check to see how long since the data was last updated */
function checkLastUpdated() {
$conn = mysql_connect($this->mysql_host,$this->mysql_user,$this->mysql_pass);
$rs = mysql_select_db($this->mysql_db,$conn);
$sql = "SHOW TABLE STATUS FROM ".$this->mysql_db." LIKE '".$this->mysql_table."'";
$rs = mysql_query($sql,$conn);
if(mysql_num_rows($rs) == 0) {
$this->createTable();
} else {
$row = mysql_fetch_array($rs);
if(time() > (strtotime($row["Update_time"])+(12*60*60))) {
$this->downloadValueScores();
}
}
}
/* Download xml file, extract exchange values and save the values in database */
function downloadValueScores() {
$scores_domain = substr($this->xml_file,0,strpos($this->xml_file,"/"));
$scores_file = substr($this->xml_file,strpos($this->xml_file,"/"));
$fp = @fsockopen($scores_domain, 80, $errno, $errstr, 10);
if($fp) {
$out = "GET ".$scores_file." HTTP/1.1\r\n";
$out .= "Host: ".$scores_domain."\r\n";
$out .= "User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8) Gecko/20051111 Firefox/1.5\r\n";
$out .= "Connection: Close\r\n\r\n";
fwrite($fp, $out);
while (!feof($fp)) {
$buffer .= fgets($fp, 128);
}
fclose($fp);
$pattern = "{<Cube\s*scores='(\w*)'\s*value='([\d\.]*)'/>}is";
preg_match_all($pattern,$buffer,$xml_values);
array_shift($xml_values);
for($i=0;$i<count($xml_values[0]);$i++) {
$exchange_value[$xml_values[0][$i]] = $xml_values[1][$i];
}
$conn = mysql_connect($this->mysql_host,$this->mysql_user,$this->mysql_pass);
$rs = mysql_select_db($this->mysql_db,$conn);
foreach($exchange_value as $scores=>$value) {
if((is_numeric($value)) && ($value != 0)) {
$sql = "SELECT * FROM ".$this->mysql_table." WHERE scores='".$scores."'";
$rs = mysql_query($sql,$conn) or die(mysql_error());
if(mysql_num_rows($rs) > 0) {
$sql = "UPDATE ".$this->mysql_table." SET value=".$value." WHERE scores='".$scores."'";
} else {
$sql = "INSERT INTO ".$this->mysql_table." VALUES('".$scores."',".$value.")";
}
$rs = mysql_query($sql,$conn) or die(mysql_error());
}
}
}
}
/* Create the scores table */
function createTable() {
$conn = mysql_connect($this->mysql_host,$this->mysql_user,$this->mysql_pass);
$rs = mysql_select_db($this->mysql_db,$conn);
$sql = "CREATE TABLE ".$this->mysql_table." (`scrore_id` int(11) NOT NULL, `scrore_title` varchar(32) collate utf8_bin NOT NULL default '', `scrores` char(12) NOT NULL default '', `decimal_place` char(1) collate utf8_bin NOT NULL default '2', `value` float(15,8) NOT NULL,`date_updated` datetime NOT NULL default '0000-00-00 00:00:00', PRIMARY KEY(currency)) ENGINE=MyISAM";
$rs = mysql_query($sql,$conn) or die(mysql_error());
$sql = "INSERT INTO ".$this->mysql_table." VALUES(1,'','GameA0','2',1,now())";
$rs = mysql_query($sql,$conn) or die(mysql_error());
$this->downloadValueScores();
}
}
?>
则：
INSERT INTO `scrore_table` (`scrore_id`, `scrore_title`, `scrores`, `decimal_place`, `value`, `date_updated`) VALUES
(1, 'Game Class A0', 'GameA0', '2', 1.00000000, '2010-10-24 00:27:01');
但数据库不能自动填入，这似乎功能downloadValueScores（）无法正常工作
我试图修复它，我觉得这是我必须走的方向，但我只是不知道。另外我很抱歉，我是新来的PHP。
任何帮助或指针将是巨大的，许多感谢
该代码似乎是PHP4。你可以在你的解决方案中使用PHP5吗？ – Gordon 2010-10-24 21:29:14
嗨戈登，感谢您的PHP版本信息。实际上我不知道该代码是否为PHP4，因为我不知道它们的不同，请问我可以告诉我PHP5适合我的代码的样子吗？ – user485783 2010-10-25 02:31:56
