不在for循环中显示第一个标记

Question

我只插入两个items只是为了查看xml的外观。循环显示在每个item image：＆＃39; 1.gif＆＃ 39;但不在第一项中。在第一项中显示默认标记 任何想法我将如何在第一项中使用图像标记（1.gif）？

var map;
        var infowindow;
            function initialize() {
            var myLatlng = new google.maps.LatLng(38.822590,24.653320);
            var myOptions = {
              zoom: 6,
              center: myLatlng,
              mapTypeId: google.maps.MapTypeId.ROADMAP
            }
            var pirkagia1  = 'pirkagia/1.gif';
            map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
            <?php foreach ( $item_array as $item ) : ?>

                            if ( parseFloat ( '<?php echo $item["fire"] ?>') == 1 ) {
                                var contentString = '<?php echo $item['title']; ?>';                
                                var latlng = new google.maps.LatLng(<?php echo $item['glat'] ?>,<?php echo $item['glon'] ?>);               
                                var marker1 = createMarker1( contentString,latlng,pirkagia1 );
                            }
            <?php endforeach; ?>

                            icon: pirkagia1
                            });
                        google.maps.event.addListener( marker1, "click", function() {
                        if (infowindow) infowindow.close();
                            infowindow = new google.maps.InfoWindow({
                            content: contentString
                            });
                            infowindow.open(map, marker1);
                        });
                        return marker1;
                        }
