[英]Normalizer fatal error with XAMPP and PHP 5.4.4
When I use the PHP class Normalizer
(eg \\Normalizer::normalize($string, Normalizer::FORM_KD);
) in my class Text.php
in custom namespace Utils
, I get the following error: 当我在自定义命名空间
Utils
类Text.php
中使用PHP类Normalizer
(例如\\Normalizer::normalize($string, Normalizer::FORM_KD);
)时,出现以下错误:
Fatal error: Class 'Utils\Normalizer' not found
in C:\xampp\htdocs\MyProject\src\Utils\text.php on line 380
My project runs under XAMPP with PHP 5.4.4 . 我的项目在XAMPP和PHP 5.4.4下运行。 I know also that:
我也知道:
Normalizer
should work since PHP 5 >= 5.3.0 . Normalizer
应该可以工作。 php_intl.dll
is enabled in my php.ini
file. php.ini
文件中启用了扩展名php_intl.dll
。 What am I missing? 我想念什么?
You forgot the leading backslash In Normalizer::FORM_KD
when calling \\Normalizer::normalize($string, Normalizer::FORM_KD)
notice you only used one backslash in front of the class name, but not when you're using the class constant . 在调用
\\Normalizer::normalize($string, Normalizer::FORM_KD)
您在Normalizer::FORM_KD
忘记了前导反斜杠 \\Normalizer::normalize($string, Normalizer::FORM_KD)
注意,您仅在类名前面使用了一个反斜杠,但在使用类常量时却没有。
In PHP when you declare or import a namespace you are telling PHP to alias all of your function, class/interface, and constant names to your namespace. 在PHP中,当您声明或导入名称空间时,就是在告诉PHP将所有函数,类/接口和常量名称都别名为名称空间。
So the following code would issue a similar fatal error... 因此,以下代码将发出类似的致命错误...
<?php
namespace foo;
var_dump(DateTime::createFromFormat('Y-m-d','2012-12-06'));
The above code would issue an error of PHP Fatal error: Class 'foo\\DateTime' not found in /testfile.php on line 4
上面的代码将发出错误的
PHP Fatal error: Class 'foo\\DateTime' not found in /testfile.php on line 4
To fix this make sure you always call those functions/classes/interfaces/constants which are not declared in your namespace/alias to the global namespace. 要解决此问题,请确保始终调用那些未在名称空间/别名中声明的函数/类/接口/常量给全局名称空间。
<?php
namespace foo;
/* Notice the leading backslash infront of DateTime*/
var_dump(\DateTime::createFromFormat('Y-m-d','2012-12-06'));
