    <p>I have data in mysql database and I want to be able to read that data in php array and use it for google geolocation.</p> <p>So for this example I want to use only <code>SELECT *</code> statement, as I will not be bothering you with some parameters...</p> <p>What I want to achieve is to get marked line from point A to point B ( depending where GPS location was saved )</p> <p>This is the link what I want to have on my map: <a href="https://google-developers.appspot.com/maps/documentation/javascript/examples/polyline-simple" rel="nofollow noreferrer">POLYLINE</a> in this example there are only 4 data in the array I want to have it more.</p> <p>So now we can get back to the code. This is my PHP script for connecting to mysql. I have been using mysqli as I will have stored procedures later one in the database, so don't get confused.</p> <pre><code>class dbMySql { static function Exec($query) { // open database $conn = mysqli_connect( $GLOBALS['cfg_db_Server'], $GLOBALS['cfg_db_User'], $GLOBALS['cfg_db_Pass'] ); if($conn === false) { throw new Exception(mysqli_connect_error()); } mysqli_select_db($conn,$GLOBALS['cfg_db_Name']); $result = mysqli_query($conn,$query); if(is_bool($result) &amp;&amp; !$result) { $error = mysqli_error($conn); mysqli_close($conn); throw new Exception($error); } mysqli_close($conn); return $result; } } </code></pre> <p>How to connect this php script to code that is example on google API page, and insert my array values when button is clicked instead of the fixed ones:</p> <pre><code>&lt;!DOCTYPE html&gt; &lt;html&gt; &lt;head&gt; &lt;meta name="viewport" content="initial-scale=1.0, user-scalable=no" /&gt; &lt;script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?key=KEY&amp;sensor=true"&gt; &lt;/script&gt; &lt;script type="text/javascript"&gt; function initialize() { var myLatLng = new google.maps.LatLng(0, -180); var myOptions = { zoom: 3, center: myLatLng, mapTypeId: google.maps.MapTypeId.TERRAIN }; var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); var flightPlanCoordinates = [ new google.maps.LatLng(37.772323, -122.214897), new google.maps.LatLng(21.291982, -157.821856), new google.maps.LatLng(-18.142599, 178.431), new google.maps.LatLng(-27.46758, 153.027892) ]; var flightPath = new google.maps.Polyline({ path: flightPlanCoordinates, strokeColor: "#FF0000", strokeOpacity: 1.0, strokeWeight: 2 }); flightPath.setMap(map); } &lt;/script&gt; &lt;/head&gt; &lt;body onload="initialize()"&gt; &lt;div id="map_canvas" style="width:100%; height:80%"&gt;&lt;/div&gt; &lt;div&gt;&lt;button type="button"&gt;Click Me!&lt;/button&gt;&lt;/div&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>EDIT:</p> <p>this is what I get when I do your code: <img src="https://i.stack.imgur.com/C00wn.png" alt="error"></p> <p>EDIT2:</p> <pre><code>&lt;!DOCTYPE html&gt; &lt;html&gt; &lt;head&gt; &lt;meta name="viewport" content="initial-scale=1.0, user-scalable=no" /&gt; &lt;style type="text/css"&gt; html { height: 100% } body { height: 100%; margin: 0; padding: 0 } #map_canvas { height: 100% } &lt;/style&gt; &lt;script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?key=key&amp;sensor=true"&gt; &lt;/script&gt; &lt;script type="text/javascript"&gt; function initialize() { var myLatLng = new google.maps.LatLng(0, 180); var myOptions = { zoom: 3, center: myLatLng, mapTypeId: google.maps.MapTypeId.TERRAIN }; var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); var flightPlanCoordinates = [ &lt;?php echo implode(',', $coordinates) ?&gt; ]; ]; var flightPath = new google.maps.Polyline({ path: flightPlanCoordinates, strokeColor: "#FF0000", strokeOpacity: 1.0, strokeWeight: 2 }); flightPath.setMap(map); } &lt;/script&gt; &lt;/script&gt; &lt;?PHP class dbMySql { static function Exec($query) { // open database $conn = mysqli_connect('localhost','root','*****'); if($conn === false) { throw new Exception(mysqli_connect_error()); } mysqli_select_db($conn,'data_gps'); $result = mysqli_query($conn,$query); if(is_bool($result) &amp;&amp; !$result) { $error = mysqli_error($conn); mysqli_close($conn); throw new Exception($error); } mysqli_close($conn); return $result; } } $coordinates = array(); $result = dbMySql::Exec('SELECT lat,lng FROM data'); while ($row = mysqli_fetch_assoc($result)) $coordinates[] = 'new google.maps.LatLng(' . $row['lat'] .

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
