SyntaxError: missing } after property list

content:Al futaim, trading company<br />Building M, 36, Saih Shuaib 3 —

PHP code

$content=$servicecenter->getCompanyName()."<br />".$servicecenter->getAddress()."<br /><button type='button' value='Get Direction' class='button' onclick='closeInfoWindow(),calcRoute()' name='Get Direction'>Get Direction</button>"; 

Script

var infowindow = new google.maps.InfoWindow({
  content:<?php echo $content; ?>;
});

Answer 1

Use json_encode and delete the semicolon at end of line:

content: <?php echo json_encode($content); ?>  /* no ; here! */

Answer 2

Missing the quotes for content and no need of ; -

content: '<?php echo $content; ?>'

OR

content: <?php echo json_encode($content); ?>

Answer 3

var infowindow = new google.maps.InfoWindow({
    content:<?php echo $content; ?>
});

You can't have a ; inside an object's declaration. If you want to separate properties, use ,.

Also, depending on what you want to echo there, you might need to add " around the php script.
