PHP代码 - 将Web服务器（/ public_html / ctrackxml）中的xml文件导入mysql数据库

Question

I have xml files been imported onto an FTP server. This is stored in location '/public_html/ctrackxml/' with a random file name and in the following format:

<message type="POSITIONDATA">
  <messageid>-1</messageid>
  <mobile>SNK261GP</mobile>
  <time>2012/01/20 08:34:45 AM</time>
  <latitude>-29.8477</latitude>
  <longitude>30.9554</longitude>
  <status>Driving</status>
  <speed>82</speed>
  <address> near Outer Ring Road (N2); Umkumbaan; in Durban</address>
  <direction>
  </direction>
  <runningodo>1587000</runningodo>
</message>

I need to loop through all the files in the folder and import each file into the MySQL database table xmldata which has the following structure:

I need each tag in the xml file to be imported into a seperate field in the table. so each xml file represent one table entry.

From the research I have done it looks like I need to use the 'LOAD XML LOCAL INFILE' mysql syntax however I cant seem to get this to work correctly directly within mysql.

If you could point me in the right direction I would greatly appreciate it.

Update

below is the code that I hav emanaged to scrape together with the assistance of another website. http://www.phpfreaks.com/forums/index.php?topic=244744.0

I tested the script from phpfreaks and it works 100% however the xml structure is quite different. I have tried to modify the code to suite my xml file but am having some issues to get this working.

my code is as follows but currently fails ont he foreach statement:

<?php

echo "starting <br><br>";
//mysql connection
$con2 = mysql_connect("localhost","dbuser","dbpassword");
if (!$con2)  {  die('Could not connect: ' . mysql_error());  }
$selectdb = mysql_select_db("dbname", $con2);
if (!$selectdb)  { die('Database not used: ; ' . mysql_error());  }

echo "connected to DB<br/><br/>";

//simplexml load xml file   
$library =  simplexml_load_file('http://www.website/ctrackxml/CTO_20120119140006_0000.xml');

echo "xml loaded<br/><br/>";

//loop through parsed xmlfeed and print output      

foreach ($message->message as $message) {                  
printf("messageid: %s
", $messageid->messageid);                  
printf("mobile: %s
", $mobile->mobile);
printf("time: %s
", $time->time);
printf("latitude: %s
", $latitude->latitude);
printf("longitude: %s
", $longitude->longitude);
printf("status: %s
", $status->status);
printf("speed: %s
", $speed->speed);
printf("address: %s
", $address->address);
printf("direction: %s
", $direction->direction);
printf("runningodo: %s
", $runningodo->runningodo);

echo "xml parsed<br/><br/>";

//insert into databse                     
mysql_query("INSERT INTO xml (messageid, mobile, time,latitude,longitude,status,speed,address,direction,odometer)
VALUES (\"$messageid->messageid\", \"$mobile->mobile\", \"$time->time\", \"$latitude->latitude\", \"$longitude->longitude\", \"$status->status\", \"$speed->speed\", \"$address->address\", \"$direction->direction\", \"$runningodo->runningodo\")")
or die(mysql_error());

echo "inserted into mysql<br/><br/>";

//show updated records            
printf ("Records inserted: %d
", mysql_affected_rows());  
}


//close connection 
mysql_close($con2);

?>

Thanks as always to everyone for the help.

<?php

ini_set('display_errors','On');

echo "starting";

//mysql connection
$con2 = mysql_connect("localhost","dbuser","dbpass");
if (!$con2)  {  
    die('Could not connect: ' . mysql_error());  
}

$selectdb = mysql_select_db("dbname", $con2);
if (!$selectdb)  { 
    die('Database not used: ; ' . mysql_error());  
}

echo "connected to DB<br /><br />";

// Read filenames in current directory looking for XML files
$file_arr = array();
if ($handle = opendir('.')) {
    while (false !== ($file = readdir($handle))) {
        if (($file != ".") && ($file != "..")) {
            if(substr($file, -4) == ".xml")
            {
                array_push($file_arr, $file);
            }
        }
    }
    closedir($handle);
}

// Loop through each XML file in the current directory
foreach($file_arr as $filename)
{
    //simplexml load xml file   
    $mess = simplexml_load_file($filename);
    echo "xml loaded<br /><br />";

    $messageid = mysql_real_escape_string($mess->messageid);
    $mobile = mysql_real_escape_string($mess->mobile);
    $time = mysql_real_escape_string($mess->time);
    $latitude = mysql_real_escape_string($mess->latitude);
    $longitude = mysql_real_escape_string($mess->longitude);
    $status = mysql_real_escape_string($mess->status);
    $speed = mysql_real_escape_string($mess->speed);
    $address = mysql_real_escape_string($mess->address);
    $direction = mysql_real_escape_string($mess->direction);
    $runningodo = mysql_real_escape_string($mess->runningodo);

    echo "xml parsed<br /><br />";

    //insert into databse                     
    mysql_query("INSERT INTO xml (messageid, mobile, time, latitude, longitude, status, speed, address, direction, odometer)
    VALUES ('$messageid', '$mobile', '$time', '$latitude', '$longitude', '$status', '$speed', '$address', '$direction', '$runningodo')")
    or die(mysql_error());

    echo "inserted into mysql<br /><br />";

    //show updated records            
    printf ("Records inserted: %d
", mysql_affected_rows());  
}
//close connection 
mysql_close($con2);

?>

The above code should achieve what you are looking for based on the spec. As stated there is one XML record per one XML file.

This code is designed to run in the same directory as the XML files, you can easily change this by editing opendir command in the code. It will read all the XML files in the current working directory and place the data into the Database.
