php startup :unable to load dynamic library

Question

我正在警告php启动：无法加载动态库'C：/wamp/bin/php/php5.5.12/ext/php_intl.dll'-％1不是有效的Win32应用程序。

Answer 1

That is due to invalid dll file.

first you need to find

• Architecture - 32 bit ot 64 bit
• compiler version - VC9 or VC11
• Thread safe or Non thread safe

this can be find by open phpinfo or echoing phpinfo() in any php file. then search for Compiler , Architecture and Thread Safety

then go to http://windows.php.net/download/ and download right Releases. replace needed file then restart web server
