Webservice PHP

Boas,

Eu tou a tentar criar um webservice que faz uma chamada a uma api via ajax e me devolve o array ja tratado mas ele nao me esta a passar a variável para o lado do cliente o que poderá estar mal alguém me pode ajudar?

Server

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.js"	type="text/javascript">	</script>
<script>
	var line_points = new Array;
	var line_points2 = new Array;
	function ponts (lat1,long1,lat2,long2) {
	$.ajax({

 url : "https://graphhopper.com/api/1/route?point.....",
 type : "GET",
 async: true,
 dataType : "json",
 success : function(keydata) {
 // Create array of lat,lon points
 var arr = new Array;
 var line_points = new Array;
 var data = keydata.paths[0].points.coordinates;
 for (var prop in data) {
 arr.push(data[prop]);
 }
 for (var alt in arr) {
 var arr2 = new Array;
 arr2.push(arr[alt][1]);
 arr2.push(arr[alt][0]);
 line_points.push(arr2);
 }
 console.log("Ajax");
 console.log(line_points);
	line_points2=line_points;

	}});

return line_points2;
}
</script>
<?php

$server = new SoapServer(null, array('uri' => "http://localhost:8888/soap/"));
 function getpoints($lat1 , $long1, $lat2, $long2) {
 echo '<script type="text/javascript">ponts('.$lat1.','.$long1.','.$lat2.','.$long2.');
 </script>';
$x = "<script>document.write(line_points2)</script>";
return $x ;
}

$server->addFunction("getpoints");
if ($_SERVER["REQUEST_METHOD"]== "POST") {
 $server->handle();

} else {

	$functions = $server->getFunctions();
	foreach ($functions as $func) {
 print $func. "<br>";
	}
}
?>

Cliente

<?php
$client = new SoapClient(null, array(
	'location' => 'http://localhost:8888/soap3/server.php',
	'uri' => 'http://localhost:8888/soap/',
	'trace' => 1));
$result = $client->getpoints("41.695242","-8.84232","41.69489","-8.833072");
 if (is_soap_fault($result)){
	echo trigger_error("SOAP Fault: (faultcode: {$result->faultcode},
	faultstring: {$result->faulstring})", E_ERROR);
}

else{

	print_r($result);
}
?>

Obrigado .
