PHP says it can’t find extension php_intl.dll, yet file "php_intl.dll" does exist in the specified location!…
PHP Startup: Unable to load dynamic library ‘C:/wamp/path/to/php/ext/php_intl.dll’ – The specified module could not be found.
This is a very common issue, especially under PHP 5.5, and can easily be fixed.
To find out why PHP cannot load extension php_intl.dll, open the command line, change to WAMP’s PHP directory, and test the php_intl.dll dependencies (i.e., the other DLL files it needs):
C: cd \WampDeveloper\Components\Php deplister.exe ext\php_intl.dll
This is a list of all the DLL files php_intl.dll must load itself, before PHP can load it:
# Core PHP DLL php5ts.dll,OK # International Components for Unicode (ICU) libraries - Unicode and Globalization support icuuc51.dll,OK icuin51.dll,OK icuio51.dll,OK # Microsoft VC++ 2012 Runtime libraries - common functions required by C and C++ programs MSVCR110.dll,OK MSVCP110.dll,OK # Core Windows DLL KERNEL32.dll,OK
On a system with this issue, either the “ICU” or the “VC++ Runtime” DLL files will not be found (i.e., shown as “
NOTFOUND” instead of “
OK” in the above output).
php_intl.dll is not able to find and load these dependencies, PHP outputs:
"The specified module could not be found."
Here is how to fix the issue and load
1. Make sure the PHP directory path is included in the system’s
PATH environmental variable so this set of provided/included ICU DLLs, that php_intl.dll depends on, are found:
icuuc51.dll, icuin51.dll, icuio51.dll
* WampDeveloper Pro already includes PHP’s directory in
PATH, but some other WAMP distributions do not.
2. Install the Microsoft VC++ 2012 Runtime Redistributable that will provide these VC11 runtime DLLs that php_intl.dll depends on (PHP 5.5 is built with VS.NET 2012):
Make sure to install the 32 bit (x86) version if you are using a 32 bit PHP build: vcredist_x86.exe
* Unlike PHP 5.5, PHP 5.3 is built with VS.NET 2008 (VC9), and depends on “Visual C++ Redistributable for Visual Studio 2008″ which provides runtime DLLs: MSVCR90.dll, MSVCP90.dll
