由于某种原因,“描述”项将返回NULL以下代码:
NULL
<?php include('db.php'); $result = mysql_query('SELECT * FROM `staff` ORDER BY `id` DESC LIMIT 2') or die(mysql_error()); $rows = array(); while($row = mysql_fetch_assoc($result)){ $rows[] = $row; } echo json_encode($rows); ?>
这是我的数据库的架构:
CREATE TABLE `staff` ( `id` int(11) NOT NULL AUTO_INCREMENT, `name` longtext COLLATE utf8_unicode_ci, `description` longtext COLLATE utf8_unicode_ci, `icon` longtext COLLATE utf8_unicode_ci, `date` longtext COLLATE utf8_unicode_ci, `company` longtext COLLATE utf8_unicode_ci, `companyurl` longtext COLLATE utf8_unicode_ci, `appurl` longtext COLLATE utf8_unicode_ci, PRIMARY KEY (`id`) ) ENGINE=MyISAM AUTO_INCREMENT=5 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci
这是页面上呼应的内容:
[{"id":"4","name":"Noter 2","description":null,"icon":"http:\/\/images.apple.com\/webapps\/productivity\/images\/noter2_20091223182720-thumb.jpg","date":"1262032317","company":"dBelement, LLC","companyurl":"http:\/\/dbelement.com\/","appurl":"http:\/\/noter2.dbelement.com"},{"id":"3","name":"Noter 2","description":null,"icon":"http:\/\/images.apple.com\/webapps\/productivity\/images\/noter2_20091223182720-thumb.jpg","date":"1262032317","company":"dBelement, LLC","companyurl":"http:\/\/dbelement.com\/","appurl":"http:\/\/noter2.dbelement.com"}]
有任何想法吗?
我敢打赌,您正在以非utf8编码检索数据:请尝试mysql_query('SET CHARACTER SET utf8')在SELECT查询之前输入。
mysql_query('SET CHARACTER SET utf8')
SELECT
