Parse KML file with PHP - php

Question

Is there a way to parse google maps *.kml file with simple_xml_load_file("*.kml") ?
I need to save in my database name and coordinates of each polygons registered in my KML file.
On my PHP script, simple_xml_load_file("*.kml") return false, so I can't read it.
<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://www.opengis.net/kml/2.2" xmlns:gx="http://www.google.com/kml/ext/2.2" xmlns:kml="http://www.opengis.net/kml/2.2" xmlns:atom="http://www.w3.org/2005/Atom">
<Document>
<Schema>
...
</Schema>
<Style id="FEATURES">
...
</Style>
<Folder>
<Placemark>
<name>
name
</name>
<Polygon>
<LinearRing>
<coordinates>
coordinates
</coordinates>
</LinearRing>
</Polygon>
</Placemark>
<Placemark>
...
</Placemark>
</Folder>
</Document>
</kml>
I need "name" and "coordinates" values for each "Placemark".

Answer 1

The xml structure is exactly that xml you sent:
For example:
<Document>
<Placemark>
<name>356HH</name>
<description>
</description>
<Polygon><outerBoundaryIs><LinearRing><coordinates>some cordinates here</coordinates></LinearRing></innerBoundaryIs></Polygon>
<Style><LineStyle><color>ff0000ff</color></LineStyle> <PolyStyle><fill>0</fill></PolyStyle></Style>
</Placemark>
<Placemark>
</document>
And it's my php code:
<?php
$completeurl = "2.xml";
$xml = simplexml_load_file($completeurl);
$placemarks = $xml->Document->Placemark;
$con=mysqli_connect("localhost","root","","j3");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$query = '';
$run='';
for ($i = 0; $i < sizeof($placemarks); $i++) {
$coordinates = $placemarks[$i]->name;
$cor_d = explode(' ', $placemarks[$i]->Polygon->outerBoundaryIs->LinearRing->coordinates);
$qtmp=array();
foreach($cor_d as $value){
$tmp = explode(',',$value);
$ttmp=$tmp[1];
$tmp[1]=$tmp[0];
$tmp[0]=$ttmp;
$qtmp[]= '(' . $tmp[0] . ',' .$tmp[1].')';
}
$cor_d = json_encode($qtmp);
$query .='\''.$coordinates.'\', \''.$cor_d.'\'';
$run .="INSERT INTO jos_rpl_addon_zipinfo (name, boundary) VALUES (".$query." );";
//echo $run;
//break;
}
mysqli_query($con,$run);
//echo $run;
mysqli_close($con);
?>

Answer 2

The first line:
<?xml version="1.0" encoding="UTF-8"?>
Tells PHP that this is a document encoded in UTF-8, but your error says it is not encoded as UTF-8. Is this a doc you created with a text editor? If so, you can usually use your editor to save it out in UTF-8. Or you can probably use PHP to detect the encoding and change that first line.

If the XML strucutre is as what you have posted, you can try :-
$xml = simplexml_load_file(...);
$childs = $xml->Document->Folder->children();
foreach ($childs as $child)
{
// child object is same as -> Placemark
}
Example :-
SimpleXMLElement Object
(
[name] =>
name
[Polygon] => SimpleXMLElement Object
(
[LinearRing] => SimpleXMLElement Object
(
[coordinates] =>
coordinates
)
)
)
