同一個編輯器EclipsePHP Studio v1.2.2編寫的兩個頁面，print_r輸出為何字型大小格式不一致？結果導致三級省市聯動用ajax.php正常，用osg_ajax.php不正常
ajax.php中代碼如下：
header("Content-Type:text/html;charset=gbk");
$sql = "SELECT * FROM `ecs_region` WHERE `parent_id` = '1' ORDER BY `region_id` ASC ";
$list = $db->getAll($sql);
foreach ($list as $key => $val ) {
$list[$key]['region_name'] = urlencode (iconv ('gbk','utf-8',$val['region_name']));
}
print_r (json_encode ($list));

輸出結果如下：

osg_ajax.php
代碼如下：
$sql = "SELECT * FROM `osg_region` WHERE `parent_id` = '1' ORDER BY `region_id` ASC ";

$cursor = exequery( $connection, $sql);

while($rows=mysql_fetch_assoc( $cursor )){
$arr[]=$rows;
}

foreach ($arr as $key => $val )
{
$arr[$key]['region_name'] = urlencode (iconv ('gbk','utf-8',$val['region_name'])); //

}

print_r (json_encode ($arr));
