Unable to load dynamic library 'c:/wamp/bin/php/php5.5.12/ext/php_intl.dll'

问题

I am attempting to connect from an android app to mySQL database within the WAMP server. I am getting this error consistently throughout my php_error log:

PHP Startup: Unable to load dynamic library 'c:/wamp/bin/php/php5.5.12/ext/php_intl.dll'
             The specified module could not be found.

in Unknown on line 0

When I click on the Apache>Version>2.4.9 I get the 2 following errors as pop ups:

The program cant start because icuuc51.dll is missing from your computer.
Try reinstalling the program to fix this problem

and

PHP startup: unable to load dynamic library 'c/wamp/bin/php/php5.5.12/ext/php_intl.dll'
The specified module could not be found.

Does anyone know what is causing this or any potential solutions?

回答1:

This can be corrected very simply as follows.

Using the wampmanager menus do the following :-

left click wampmanager -> Apache -> Version

and then click the version number, probably 2.4.9

This will cause WAMPServer to rebuild of all the SYMLINK's in the apache2.4.9/bin folder and that will put the correct symlinks in there for these 2 extensions.

TO CORRECT THE SECOND ISSUE

Edit the \wamp\script\config.inc.php file and find the code that sets this variable $phpDllToCopy and replace it with this code.

$phpDllToCopy = array (
    'icudt52.dll', //[modif oto] - Ajouts pour éviter unknown error PHP 5.6.a2

You simply need to install Visual C++ Redistributable for Visual Studio 2012 Update 4

I think you have to copy these files

icudt.dll
icudt46.dll
icuin.dll
icuin46.dll
icuio.dll
icuio46.dll
icule.dll
icule46.dll
iculx.dll
iculx46.dll
icutest.dll
icutest46.dll
icutu.dll
icutu46.dll
icuuc.dll
icuuc46.dll

to the location <wamp_installation_path>/bin/apache/apache2.2.22/bin/.

See here for details.

First check if the mentioned file (php_intl.dll) is under c:\wamp\bin\php5.5.12\ext folder.
If so, open the following file with notepad:
c:\wamp\bin\php5.5.12\php.ini
and check if you can find the following line (important: should not have ; sign before the word 'extension'):
extension=php_intl.dll
