Zend_Cache：加载缓存数据后，字符编码似乎搞乱了 [英] Zend_Cache: After loading cached data, character encoding seems messed up
问题描述
第一;在我的开发服务器（localhost; OSX上的默认XAMPP）一切正常，虽然当我部署完全相同的代码（和数据）到临时服务器（托管Apache2在Redhat上）。
我使用Zend_Cache缓存一些数据使用文件后端和自动序列化。
原始数据中使用的特殊字符显示正常，但是当从缓存加载时，它们都显示为乱码。
任何人都有一个线索？ p>
PS。而不是一种解决方法，我正在寻找一种方法来了解在登台服务器上可能会错误。
b b b b b b b b b UPDATE
当查看原始缓存文件（一个序列化数组）时，我看到一个大的区别;
当在临时服务器上缓存的（相同）数据显示换行符时，在我的localhost上缓存的数据不显示换行符。
UPDATE
本地服务器运行 PHP 5.3 ，暂存服务器运行 PHP 5.2.10
UPDATE
在Zend FW 1.10.8上运行
，
我几乎和你一样的状态，
开发机器是windows + php 5.3
开发机器是Linux + php 5.2.14
ZF版本是1.10
我唯一的区别是：我用来在引导类
中添加 mb_internal_encoding（UTF-8）; FYI，我用来缓存来自数据库的文本（阿拉伯语）所有编码的UTF8
当我打开文件，我看到阿拉伯文本如预期。
UPDATE ：
1-这里是我完整的initCache函数，只是为了清楚
public function _initCache（）{
mb_internal_encoding（UTF-8）;
$ frontendOptions = array（
'automatic_serialization'=> TRUE，
'lifetime'=> 86400
）;
$ backendOptions = array（
'cache_dir'=> APPLICATION_PATH。/ configs / cache /，
///'cache_dir'=> sys_get_temp_dir（），
）;
$ cache = Zend_Cache :: factory（'Core'，'File'，$ frontendOptions，$ backendOptions）;
Zend_Db_Table_Abstract :: setDefaultMetadataCache（$ cache）;
Zend_Registry :: set（cache，$ cache）;
}
说明：
1 php版本早于PHP 6没有本机支持UTF-8，
http://stackoverflow.com/questions/716703/what-is-coming-in-php-6
2制作php 5.3或5.2使用 ICONV 或 MB_STRING
只需使用 var_dump mb_internal_encoding（））;
$ b
您可以在内部使用 ISO-8859-1 >
您可以覆盖 var_dump（mb_internal_encoding（UTF-8））;
它会输出true（它成功覆盖内部编码）
说实话我不知道是否有更好的解决方案或< a href =http://stackoverflow.com/questions/4045060/how-bad-is-mb-internal-encodingutf-8>这有多糟糕，
如果你有更好的，我会很乐意采用它:)
UPDATE 2
case你不想使用该函数，
打开此文件Zend / Cache / Backend / File.php并转到第976行$ b改变这个：
protected function _filePutContents（$ file，$ string）
{
$ result = false;
$ f = @fopen（$ file，'ab +'）;
if（$ f）{
if（$ this-> _options ['file_locking']）@flock（$ f，LOCK_EX）;
fseek（$ f，0）;
ftruncate（$ f，0）;
$ tmp = @fwrite（$ f，$ string）;
if（！（$ tmp === FALSE））{
$ result = true;
}
@fclose（$ f）;
}
@chmod（$ file，$ this-> _options ['cache_file_umask']）;
return $ result;
}
为：
protected function _filePutContents（$ file，$ string）
{
$ string = mb_convert_encoding（$ string，UTF-8，ISO-8859- 1）; //我没有测试它，使用它在自己的风险，我宁愿坚持第一个解决方案
$ result = false;
$ f = @fopen（$ file，'ab +'）;
if（$ f）{
if（$ this-> _options ['file_locking']）@flock（$ f，LOCK_EX）;
fseek（$ f，0）;
ftruncate（$ f，0）;
$ tmp = @fwrite（$ f，$ string）;
if（！（$ tmp === FALSE））{
$ result = true;
}
@fclose（$ f）;
}
@chmod（$ file，$ this-> _options ['cache_file_umask']）;
return $ result;
}
我没有手动测试，但它应该按预期工作
很高兴帮助！
First; On my development server (localhost; default XAMPP on OSX) everything works fine, though when I deploy the exact same code (and data) to the staging server (managed Apache2 on Redhat) it breaks.
I'm caching some data using Zend_Cache using the File backend and auto-serialization. Special characters used in the original data display fine, though when they are loaded from cache they're all garbled up.
Anyone got a clue?
PS. Instead of just a workaround, I'm looking for a way to understand what might go "wrong" on the staging server. What could possibly mess this up?
UPDATE The data I'm caching is UTF-8 encoded.
UPDATE When looking at the raw cache files (of a serialized array) there i See one big difference; The data cached on my localhost shows no newlines when the (identical) data cached on the staging server does show newlines.
UPDATE
Local server runs PHP 5.3, staging server runs PHP 5.2.10
UPDATE Running on Zend FW 1.10.8
, I have almost identical state like you ,
development machine is windows + php 5.3
development machine is Linux + php 5.2.14
ZF version is 1.10
the only difference i had is : i used to add mb_internal_encoding("UTF-8"); in the bootstrap class
FYI , I used to cache text (arabic language ) from database all encoded UTF8 when i open the file i see the arabic text as expected .
UPDATE : 1- here is my complete initCache function just to make it clear
public function _initCache() {
mb_internal_encoding("UTF-8");
$frontendOptions = array(
'automatic_serialization' => TRUE,
'lifetime' => 86400
);
$backendOptions = array(
'cache_dir' => APPLICATION_PATH . "/configs/cache/",
///'cache_dir' => sys_get_temp_dir(),
);
$cache = Zend_Cache::factory('Core', 'File', $frontendOptions, $backendOptions);
Zend_Db_Table_Abstract::setDefaultMetadataCache($cache);
Zend_Registry::set("cache", $cache);
}
Explanation : 1-Any php version earlier than PHP 6 doesn't have native support for UTF-8 , http://stackoverflow.com/questions/716703/what-is-coming-in-php-6
2-making php 5.3 or 5.2 deal with UTF8 by using ICONV or MB_STRING
simply by using var_dump(mb_internal_encoding());
you can tell that php using ISO-8859-1 internally ,
you can override it by var_dump(mb_internal_encoding("UTF-8"));
it would output true (it success to override the internal encoding )
to be honest i don't know if there is better solution or how bad it is ?? ,
if you had any better i would be happy to adopt it :)
UPDATE 2
in case you don't want to use that function ,
open this file "Zend/Cache/Backend/File.php" and go to the line 976
change this :
protected function _filePutContents($file, $string)
{
$result = false;
$f = @fopen($file, 'ab+');
if ($f) {
if ($this->_options['file_locking']) @flock($f, LOCK_EX);
fseek($f, 0);
ftruncate($f, 0);
$tmp = @fwrite($f, $string);
if (!($tmp === FALSE)) {
$result = true;
}
@fclose($f);
}
@chmod($file, $this->_options['cache_file_umask']);
return $result;
}
to be this :
protected function _filePutContents($file, $string)
{
$string = mb_convert_encoding($string , "UTF-8" , "ISO-8859-1"); // i didn't test it , use it at your own risk and i'd rather stick with the first solution
$result = false;
$f = @fopen($file, 'ab+');
if ($f) {
if ($this->_options['file_locking']) @flock($f, LOCK_EX);
fseek($f, 0);
ftruncate($f, 0);
$tmp = @fwrite($f, $string);
if (!($tmp === FALSE)) {
$result = true;
}
@fclose($f);
}
@chmod($file, $this->_options['cache_file_umask']);
return $result;
}
i didn't test manually but it should work as expected
Glad it helped !
