为什么有的页面乱码,为什么有的乱码不乱码?有点晕

Jun 23, 2016 pm 01:40 PM

请看这两个页面:http://www.qgren.com/qigong/gongfa/15_30.shtml
摘要出现乱码。

再看这个页面:http://www.qgren.com/qigong/gongfa/15_28.shtml
摘要没有乱码,很正常。

在网站,部分页面正常,部分页面摘要乱码。我有点晕。
程序是dedecms,gbk版本。我网页模板也是gbk。

调用摘要的代码如下:
{dede:field.description runphp='yes'}
if(@me'' )@me = '

摘要:'.@me.'

 ';
{/dede:field.description}

不知道谁能解我疑惑,为什么会这样?

无余没、无余欲 後有特殊字符。
?查一下。

被加入了空格,删掉即可
观察到 meta 中是一样的乱码,所以就从 meta 中取了

$t = get_meta_tags('http://www.qgren.com/qigong/gongfa/15_30.shtml');echo '乱码:', $s = $t['description'], PHP_EOL;echo '还原:', str_replace(' ', '', $s);

虽然看到的是所谓的空格,但也可能是某个汉字的变异
所以请核对文字后告知差异

找到共同规律,都是一个字后接一个句号。
版主看看

无余没、无余欲 後有特殊字符。
?查一下。


无余没、无余欲 后面并没有特殊字符,见文档。后面是 尽。
无余灭、无余没、无余欲尽。当知是人胜进不退。

$t = get_meta_tags('http://www.qgren.com/qigong/gongfa/15_30.shtml');$s = $t['description'];$n = strpos($s, '欲')+2;$t = substr($s, $n);echo bin2hex('尽。当'), PHP_EOL;echo bin2hex($t), PHP_EOL;$n = strpos($s, '而')+2;$t = substr($s, $n);echo bin2hex('取。人'), PHP_EOL;echo bin2hex($t), PHP_EOL;echo str_replace(' ', "\xa1\xa1", $s), PHP_EOL;echo bin2hex(' '); //再看看全角空格

很显然,你在处理文字时做了将全角空格替换成半角空格的处理
这就是问题的根源!

还是有点乱码,人筹量人人 ?。多了一个怪异的东东。

我把你这段代码试过了,有点纳闷,纳闷的是
echo str_replace(' ', "\xa1\xa1", $s);
这段代码后面不输出东西, ?,这个怪异的东东就不会出现。
反之,只要后面输出什么,比如你的代码,输出个PHP_EOL, ?就出现了。
真的好奇怪啊

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
