PHP 字符串编码错误

Question

我正在尝试获取以下代码以输出带有 Google Static Maps API http://code.google.com/apis/maps/documentation/staticmaps/#Imagesizes URL 的 IMG 标签嵌入其中...结果是除了 $address 之外的所有内容都已成功输出...我做错了什么？

function event_map_img($echo = true){
    global $post;
    $address = get_post_meta($post->ID, 'date_address', true);
    if($echo): echo '<img src="'.'http://maps.google.com/maps/api/staticmap?center='.$address.'&zoom=14&size=700x512&maptype=roadmap&markers=color:blue|label:X|'.$address.'&sensor=false" />';
    else:
        return '<img src="'.'http://maps.google.com/maps/api/staticmap?center='.$address.'&zoom=14&size=700x512&maptype=roadmap&markers=color:blue|label:X|'.$address.'&sensor=false" />';
    endif;
}

试试这个:

function event_map_img($echo = true) {
    global $post;
    $address = urlencode(get_post_meta($post->ID, 'date_address', true));
    $src = htmlspecialchars('http://maps.google.com/maps/api/staticmap?center='.$address.'&zoom=14&size=700x512&maptype=roadmap&markers=color:blue|label:X|'.$address.'&sensor=false');
    if ($echo) {
        echo '<img src="'.$src.'" />';
    } else {
        return '<img src="'.$src.'" />';
    }
}
