DMS to WGS84

[MiCR0]

I am trying to work out how to convert DMS to WGS84

 

I have the coordinate in mysql like

 

latitude                    longitude

52°39'03.1 N          0°40'36.1 E

52°46'45.2 N         0°06'59.9 W

 

I need to make them WGS84 and I find a functions

 

<?php
function DMStoDEC($deg,$min,$sec)
{
// Converts DMS ( Degrees / minutes / seconds ) 
// to decimal format longitude / latitude

    return $deg+((($min*60)+($sec))/3600);
}    

function DECtoDMS($dec)
{
// Converts decimal longitude / latitude to DMS
// ( Degrees / minutes / seconds ) 

// This is the piece of code which may appear to 
// be inefficient, but to avoid issues with floating
// point math we extract the integer part and the float
// part by using a string function.

    $vars = explode(".",$dec);
    $deg = $vars[0];
    $tempma = "0.".$vars[1];

    $tempma = $tempma * 3600;
    $min = floor($tempma / 60);
    $sec = $tempma - ($min*60);

    return array("deg"=>$deg,"min"=>$min,"sec"=>$sec);
}   

I had a go at it doing

$lat = explode("°",$data->latitude);
$lat2 = explode("'",$lat[1]);
$lat3 = explode(" ",$lat2[1]);

$longitude = explode("°",$data->longitudeitude);
$longitude2 = explode("'",$longitude[1]);
$longitude3 = explode(" ",$longitude2[1]);

	echo $lat['0'].'-'.$lat2[0].'-'.$lat3[0];
echo '<br/>';
echo $longitude['0'].'-'.$longitude[0].'-'.$longitude[0];

echo  DMStoDEC($lat['0'],$lat2[0],$lat3[0]); 
echo DMStoDEC($longitude['0'],$longitude2[0],$longitude3[0]);
?>

 

I am stuck any help would be great.
