$proquery ="select * from #@__keyproduct where typeid='".$id."' order by corank asc";
$dsql->SetQuery($proquery);
$dsql->Execute();
$i=0;
while($row = $dsql->GetArray()) {
$arrystr.='{"id":"'.$row["id"].'","title":"'.$row["goodstitle"].'","goodsTitle":"'.$row["goodstitle"].'","price":"'.$row

$i++;
}
if($i>0){ $arrystr=substr($arrystr,0,$arrystr.lenght-1); }
如果这样写
$a='{"status":"1","result":['.$arrystr.'],"moreUrl":"'.$moreurl.'"}';
AJAX返回 {"status":"1","result":[],"moreUrl":"http:\/\/"}
result 是空的
如果下面这样写就是正常
//$a='{"status":"1","result":[{"id":"1","title":"补水润肤膏 真的很好 很补水 皮肤有弹性","goodsTitle":"补水润肤膏 真的很好很补水 皮肤有弹","price":"59.9","imgUrl":"http:///sadas213/","goodsUrl":"http:///uploads/allimg/c131205/

$a = iconv("gbk", "UTF-8", $a);
$a=json_decode($a, true);
echo json_encode($a);
请大神们指教一下 谢谢!
回复讨论(解决方案)
$r['a'] = 123;echo json_encode($r); //得到 {"a":123}$a[] = $r;$a[] = $r;$a[] = $r;echo json_encode($a); //得到 [{"a":123},{"a":123},{"a":123}]
你应该知道怎么写了吧?
虽然 php 的 json 函数只支持 utf-8 编码,但你可以要求数据库返回 utf-8 编码的数据
版主您好 我将代码修改成这样 可还是不行 我是学.net的 Php实在太差 麻烦您在指导一下 谢谢
$a=array();
while($row = $dsql->GetArray()) {
$a[]= $row;
}
$a='{"status":"1","result":'.json_encode($a).',"moreUrl":"'.$moreurl.'"}';
$a = iconv("gbk", "UTF-8", $a);
$a=json_decode($a, true);
echo json_encode($a);
AJAX返回 {"status":"1","result":[],"moreUrl":"http:\/\/"}
result 是空的
1、你用的是什么数据库?不会是 Access 吧?
2、如果你无法让数据库返回 utf-8 编码的数据,可以这样
function gtou($s) { return iconv('gbk', 'utf-8', $s); }$a=array();while($row = $dsql->GetArray()) { $a[]= array_map('gtou', $row); }
3、这样构造输出数据
$res = array( 'status' => '1', 'result' => $a, 'moreUrl' => $moreurl,);echo join_encode($res);
版主您好 这样写 输出也是对的
但
AJAX返回 {"status":"1","result":[],"moreUrl":"http:\/\/"}
result 是空的
我的QQ 272718467 要不您加下我的QQ指导一下 或者 关注我一下 可以吗?
这样直接返回数据库读出的数据 AJAX 就可以接到 result
//$a='{"status":"1","result":[{"id":"1","title":"补水润肤膏 真的很好 很补水 皮肤有弹性","goodsTitle":"补水润肤膏 真的很好
很补水 皮肤有弹
性","price":"59.9","imgUrl":"http:///sadas213/","goodsUrl":"http:///uploads/allimg/c131205/

我是mysql数据库
$JsonStr='[ {"id":"1","name":"\u5f20\u96ea\u6885","age":"27","subject":"\u8ba1\u7b97\u673a\u79d1\u5b66\u4e0e\u6280\u672f"}, {"id":"2","name":"\u5f20\u6c9b\u9716","age":"21","subject":"\u8f6f\u4ef6\u5de5\u7a0b"} ]'; //被解析的字符串只能用?引?,而不能用?引? $Json=json_decode($JsonStr,TRUE); echo '<pre class="brush:php;toolbar:false">',var_dump($Json),''; $array=array('a'=>'A','B'=>2); $a=json_encode($array); echo '
',var_dump($a),''; $a=serialize($array); echo '
',var_dump($a),''; $a=unserialize($a); echo '
',var_dump($a),'';die();
sibang 您好 我没有找到单双引号问题 现在还是没有解决
我是 php+ajax+json
谢谢 大神们的支持 由于小弟疏忽
在AJAX请求时 路径写错
其他啥问题都没有
结贴!!!
呵呵,看来还是要仔细

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP makes it easy to create interactive web content. 1) Dynamically generate content by embedding HTML and display it in real time based on user input or database data. 2) Process form submission and generate dynamic output to ensure that htmlspecialchars is used to prevent XSS. 3) Use MySQL to create a user registration system, and use password_hash and preprocessing statements to enhance security. Mastering these techniques will improve the efficiency of web development.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

PHP remains important in modern web development, especially in content management and e-commerce platforms. 1) PHP has a rich ecosystem and strong framework support, such as Laravel and Symfony. 2) Performance optimization can be achieved through OPcache and Nginx. 3) PHP8.0 introduces JIT compiler to improve performance. 4) Cloud-native applications are deployed through Docker and Kubernetes to improve flexibility and scalability.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

PHP and Python each have their own advantages and are suitable for different scenarios. 1.PHP is suitable for web development and provides built-in web servers and rich function libraries. 2. Python is suitable for data science and machine learning, with concise syntax and a powerful standard library. When choosing, it should be decided based on project requirements.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7
