我从数据库取出数据后发到web上,让APP去获取信息:
<code>$result = mysql_query("select * from his"); while ($arr = mysql_fetch_assoc($result)) { $json = json_encode($arr,JSON_UNESCAPED_UNICODE); echo $json; }</code>
输出到界面的json为:{"hps_userid":"1","hps_userid2":"1"}
现在app端无法获取数据是我的输出格式问题还是app那边的问题?
现在app那边的同事说需要这种格式才可以
{"No.":[{"hps_userid":"1","hps_userid2":"1"}]}
当搜索到多条数据的时候,又要怎么如何输出?

“现在app那边的同事说需要这种格式才可以”,“才可以”,哈哈。。。
以前我和别人合作的时候也听到过类似的说法,然而后来我学了安卓开发。。。
妈蛋的,才发现,明明是他们解析JSON的代码不怎么会写,还怪我给的格式不对。。。
只要输出的是标准的JSON格式,信息完整,组织正确,根本不存在解析不了的问题。
<code>{"No.":[{"hps_userid":"1","hps_userid2":"1"}]} </code>
这个"No"的存在并没有什么必要(只是因为他们JSON解析不太会)。
话说,“当搜索到多条数据的时候,又要怎么如何输出?"
这种问题应该一开始就考虑好,好吧?
<code>[ { "hps_userid": "1", "hps_userid2": "1" }, { "hps_userid": "2", "hps_userid2": "3" }, { "hps_userid": "4", "hps_userid2": "5" } ] </code>
取多条数据,最后都保存到一个数组里,然后把数组转成JSON,就是上面这样的了。
话说你的代码怎么会是这样。。。
<code>$result = mysql_query("select * from his"); while ($arr = mysql_fetch_assoc($result)) { $json = json_encode($arr,JSON_UNESCAPED_UNICODE); echo $json; } </code>
你知道while循环了几次吗?每次循环都echo,最后输出的是类似这样的:
<code>{"hps_userid":"1","hps_userid2":"1"}{"hps_userid":"1","hps_userid2":"1"}{"hps_userid":"1","hps_userid2":"1"}{"hps_userid":"1","hps_userid2":"1"}{"hps_userid":"1","hps_userid2":"1"}{"hps_userid":"1","hps_userid2":"1"} </code>
这种连起来的就根本不是JSON字符串啊。。。
。。。。。。
如下:
<code>$result = mysql_query("select * from his"); $Temp = array(); $row = mysql_fetch_assoc($result); while ($row) { $Temp[] = array("hps_userid"=>$row["hps_userid"],"hps_userid2"=>$row["hps_userid2"]); $row = mysql_fetch_assoc($result); } die(json_encode($Temp)); //或者你就听你们那个逗比APP工程师的: //die(json_encode(array("No."=>$Temp))); </code>
这里是需要循环的,所以你给你们逗比工程师的json,是需要用 [{xxx:1},{xxx:2}]
这种格式的

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

The session realizes user authentication through the server-side state management mechanism. 1) Session creation and generation of unique IDs, 2) IDs are passed through cookies, 3) Server stores and accesses session data through IDs, 4) User authentication and status management are realized, improving application security and user experience.

Reasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1. Configuration error: Check and set the correct session.save_path. 2.Cookie problem: Make sure the cookie is set correctly. 3.Session expires: Adjust session.gc_maxlifetime value to extend session time.

Methods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

Configuring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
