APC - Unable to load dynamic library - php

Here is what I have in my PHP.ini:
extension=php_apc.dll
...
[APC]
apc.enabled = 1
I'm running Apache 2.0.59, PHP version 5.2.3 on Windows Server 2003.
I've already installed XDebug compiled with vc6. Thus, I got the APC version 5.2 vc6. Here are both filenames that I downloaded (and put the *.dll in php/ext/).
php_apc-3.1.5-5.2-vc6-x86.zip
php_apc-3.1.5-5.2-nts-vc6-x86.zip
I got them here.
I've tried rebooting the server and in both cases, I get the following error:
PHP Warning: PHP Startup: Unable to load dynamic library './ext/php_apc.dll' - The specified module could not be found.\r\n in Unknown on line 0

Try using the full drive letter and path to extension_dir in php.ini:
; Directory in which the loadable extensions (modules) reside.
; http://php.net/extension-dir
; extension_dir = "./"
; On windows:
extension_dir = "C:\somedir\php\ext"
And restart Apache after making the change.
(It might very well be something else, but this is the first thing I check on Windows systems -- those pesky filepaths.)

First, I went here
Then, I downloaded Collection of PECL modules for PHP 5.2.3
Then, I extracted the php_apc.dll file and copied it in the ext/ folder
Restarted Apache
It works!

To complete other answers:
Using the non thread safe (NTS) version of the DLL instead of the thread safe one solved the problem for me.
That is, only the NTS version was compatible with my WAMP installation.

You could check this:
Note: On Windows, APC needs a temp path to exist, and be writable by the web server. It checks the TMP, TEMP and USERPROFILE environment variables in that order and finally tries the WINDOWS directory if none of those are set.
http://php.net/manual/en/apc.installation.php

You have to be sure that the DLL has the correct architecture level. I had the same problem trying to load the file from php_apc-3.1.10-5.4-vc6-x86.zip. It didn't work, while the DLL from php_apc-3.1.10-5.3-vc6-x86.zip worked. I don't know how to find the right file without fiddling in the PHP repository though. HTH.

My problem was that I had listed apcu before apc.
extension=apc
extension=apcu
Reordering them so apcu was first, solved my issue.

In my case, I'm using macOS Catalina and was trying to install extension APCU for PHP 5.6.
So i ran below commands:
brew install autoconf
pecl channel-update pecl.php.net
pecl install apcu-4.0.11
At this stage my php5.6 ini got input extension="apcu.so"
But i was getting warning saying the apcu.so wasn't found under
/usr/local/lib/php/pecl/20131226/ directory.
The installer put the apcu.so at /usr/local/Cellar/php#5.6/5.6.40/pecl/20131226/apcu.so
so i copied the apcu.so to the desired directory
cp /usr/local/Cellar/php#5.6/5.6.40/pecl/20131226/apcu.so /usr/local/lib/php/pecl/20131226/
and i'm done.

php.ini extension not found Windows 10 [duplicate]

I run a PHP script and get this error:
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/local/lib/php/extensions/no-debug-non-zts-20090626/ixed.5.2.lin' - /usr/local/lib/php/extensions/no-debug-non-zts-20090626/ixed.5.2.lin: cannot open shared object file: No such file or directory in Unknown on line 0
What does that mean?
It means there is an extension=... or zend_extension=... line in one of your php configuration files (php.ini, or another close to it) that is trying to load that extension : ixed.5.2.lin
Unfortunately that file or path doesn't exist or the permissions are incorrect.
Try to search in the .ini files that are loaded by PHP (phpinfo() can indicate which ones are) - one of them should try to load that extension.
Either correct the path to the file or comment out the corresponding line.
If you're on Linux, you can find all loaded configuration files by typing this in shell:
php -r "print phpinfo();" | grep ".ini"
UPDATE:
As mentioned in comments, this can be even more accurate:
php -i | grep ini
phpStom with XAMPP
TL;DR Except from verifying that the files exist, you might need to add the drive letter to some records in your php.ini file
I suddenly started having a problem using phpStorm 7 for debugging php with xampp and xdebug. When trying to set intellij interperter to be xampps php I got a lot of the warnings like the one in the question, for example:
Unable to load dynamic library '/xampp/php/ext/php_bz2.dll'
For some reason I had to add my drive letter to the records of extension_dir and browscap in the php.ini file:
extension_dir = "\xampp\php\ext"
browscap = "\xampp\php\extras\browscap.ini"
to
extension_dir = "e:\xampp\php\ext"
browscap = "e:\xampp\php\extras\browscap.ini"
If you just want to make the error disappear, and you don't need the extension, then by all means comment the line out in php.ini. But if you actually want to fix the problem here is some additional info.
There are various causes for this based on the exact module, but there are also some general guidelines.
Open phpinfo() and look for extension_dir under the Core section. This is where your modules should be located.
For instance, /usr/lib/php/modules for Unix/Linux.
If the file does in fact exist, make sure permissions are adequate.
If the file does not exist, use the resources below to install it.

Loading .dll in Linux
I've encountered this warning message while I was trying to install a php-extension via the php.ini file;
until I figured out that you cannot load .dll extensions in Linux,
but you have to comment the extensions that you want to import ;extension= ... .dll and install it correctly via sudo apt-get install php-...
note: ... is the extension name you want to enable.
php -r "echo php_ini_loaded_file();"
Will show in CLI current ini loaded file, search there for Your extension, path to it is incorrect.
In my case, this message started to appear when I updated the php version to 7.4.
To solve it I had to look for the php.ini files found inside the php version folder (/etc/php/7.4/apache2/ && /etc/php/7.4/cli/) checking the lines where the extensions I could see that the extensions gd2 and intl were uncommented.
Note that you can also get this error if your PHP library doesn't have the "other" directory opening permission. In my particular case, I noticed this when using php -l to syntax check a script in my text editor. This meant that since my account was called "volomike", that account didn't have permission to run the libraries that the php command relied upon.
For instance, on Ubuntu 14.04, I had PHP5 installed automatically into the path /usr/lib/php5/20121212+lfs. However, because I was working in C++ in building some shared objects, I messed around with the directory permissions and screwed things up such that non-root accounts did not have the directory execute (directory open) permissions to view /usr/lib/php5/20121212+lfs. So, I typed the following command to rectify that problem:
sudo chmod o+x /usr/lib/php5/20121212+lfs.
Now when I do php -l example.php as a non-root user, it never gives me this "Unabled to load dynamic library" problem anymore.
I had the same problem on XAMPP for Windows when I try to install composer.
I did php -v and php throwing error :
Unable to load dynamic library '/xampp/php/ext/php_bz2.dll'
It took me a while until I realized that I need to setup my XAMPP. So I run setup_xampp.bat and php return to works like a charm.
I had this error on a number of modules when I had been running different versions of PHP side by side on my server. To sort this out, I needed to install the packages it couldn't find for that specific PHP version. So, for example, if I saw:-
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/20160303/xml.so'
I would install the library for the PHP version specifically:-
sudo apt-get install php7.1-xml
And then restart Apache. Fixed it for me. You can check your version like this:-
php -v
I had the same problem on XAMPP for Windows10 when I try to install composer.
Unable to load dynamic library '/xampp/php/ext/php_bz2.dll'
Then follow this steps
just open your current_xampp_containing_drive:\xampp(default_xampp_folder)\php\php.ini in texteditor (like notepad++)
now just find - is the current_xampp_containing_drive:\xampp exist?
if not then find the "extension_dir" and get the drive name(c,d or your desired drive) like.
extension_dir="F:\xampp731\php\ext" (here finded_drive_name_from_the_file is F)
again replace with finded_drive_name_from_the_file:\xampp with current_xampp_containing_drive:\xampp and save.
now again start the composer installation progress, i think your problem will be solved.
What I did was;
1 - I first find out what version of PHP I am using thru the function phpinfo()
<?php
phpinfo();
?>
2 - From there you will find the location of your configuration(php.ini) file
3 - Open that file
4 - Comment out the line similar to the image below
This might be a different value but it should be related to extension.
I am no expert but this process helped me solved similar problem.
In my case I got this error because I downloaded a thread-safe version of the dll (infixed with -ts-), but my installation of php was a non-thread-safe (infixed with -nts-). Downloading the right version of the dll, exactly matching my php installation version fixed the issue.
After Windows 10 XAMPP now I installed LAMPP (XAMPP) on Ubuntu. Windows XAMPP had a lot less to configure compare to MAC (iOS) but now with Linux Ubuntu I had a few more since there are more going in Linux (a good thing).
I confused and activated mysqli.dll (and mysql.dll: erase "#" in /etc/php/7.2/cli/php.ini
I started to get the PHP Warning: PHP Startup: Unable to load dynamic library message related to dll. I commented out mysql(and i).dll in the same file but the message didn't go away up until I commented out " " in /opt/lampp/etc/php.ini.
Looks like XAMPP reads php.ini file from /etc/php/7.2/cli and makes modification in php.ini of /opt/lampp/etc. (;extension=php_pdo_mysql.dll after ";" restarted Apache and no more any message.
I encountered a similar error. The mistake I made was to use the "controller" name as "Pages" instead of "pages" in my url.
In Windows, it could be a wrong path in "System environment variables".
"Path" to the php.exe directory must be the good one.
'C:/PHP/5.2.13/ext\php_mcrypt1.dll'
I'd say there's some typo on your php.ini (the extra 1). Perhaps you're loading a different php.ini from what you expect (see the output of php.ini to make sure).
Other than that make sure that php_mcrypt.dll and PHP:
Were linked to the same VC runtime library (typically msvcrt.dll for VC6 or msvcrt90.dll for VC9) – use e.g. the dependency walker for this
Are both debug builds or both release builds
Both have ZTS enabled or ZTS disabled
For libraries that depend on further libraries (DLLs), make sure they are available (e.g. in the same directory as the extension)
PHP should give you meaning errors if any of the first three conditions above is not satisfied, but I wrote those anyway because I'm not sure for PHP 5.2.
From C:\xampp\php\php.exe I got
Unable to load dynamic library ''
C:\xampp\php\ext\php_.dll (The specified module could not be found.)
I solved by commenting out
C:\xampp\php\php.ini
;extension=
I had the same problem when I tried to use php with sql server, when I added the sqlsrv libraries ... it gave me the error, after several days of researching there, I understood that microsoft does not support x64 in this case so what I did was install laragon x86 and use the corresponding libraries. I hope it helps with something
Go to system env variable and set the php ext dir path as
C:\xampp\php\ext
basically it's finding the ext directory and then locating it's file but it's unable to find the files becuase php path is set as different.

Configuring mongodb on MAMP

So I've tried almost all the tutorials I've found here and on other sources but the problem is always the same. The extension is not installed when I call the phpinfo method.
I've added the file mongo.so to the extensions folder and I've called it on the php.ini as extension=mongo.so.
I'm using MAMP 2.2 on Mavericks and the php version is 5.5.3.
Appreciate any kind of help.
The output of phpinfo() will tell you which php.ini file (if any) is in use.
You have to modify that php.ini file and add extension=mongo.so and then restart your webserver.
One thing you need to keep in mind when you are installing the MongoDB driver for MAMP is the pecl command you are using is actually the MAMP command, not some alternative PHP install you may have on your system.
To do this, locate the PHP binary distributed with MAMP, and the use the full path to the pecl command of the MAMP installation.

php curl works from cli but not from apache

I can't get cURL to work from inside Apache by any means. It's actually fairly strange too provided that:
I can execute my PHP pages from the CLI and it POSTs my requests perfectly fine
When I look at my error logs, I get "PHP Fatal error: Call to undefined function curl_init()" as if the extension isn't installed at all. Similarly, a quick `phpinfo()` also yields such as if the extension isn't installed.
Additionally, when I built PHP, I opted the "--enable-curl" flag.
You are probably not loading the extension in the appropriate php.ini. The file should include something like:
[PHP_CURL]
extension=php_curl.dll
Also, --enable-curl is not a PHP configure option. --with-curl=[DIR] is the one you'd want. Check out the cURL installation instructions.
php_curl.dll should be inside PHP's ext directory when configured correctly.
I had same problem after installing php5-curl. I rebooted apache and that fixed it.
sudo /etc/init.d/apache2 restart for ubuntu 12.04
I had similar problem - worked from cli, silently failed from Apache 2.4
I've tried:
1) copying ssleay32.dll and libeay32.dll from php folder into apache\bin folder - didn't work
2) deleting ssleay32.dll and libeay32.dll from apache\bin folder completely - WORKED.
You should restart apache server each time you make change to make it work.
Also you should install both x86 and x64 versions of C++ Resistributable Visual Studio from Microsoft.

Cant find the database driver for MediaWiki during installing

MYSQL and apache server are already installed on my server.
But still I encountered these problem.
I dont understand the terms to compile php with --with-mysql
Where should i compile? i am using window server.
or how to install the mysql.so module??
Checking environment...
Please include all of the lines below
when reporting installation problems.
PHP 5.2.14 installed Could not find a
suitable database driver! For MySQL,
compile PHP using --with-mysql, or
install the mysql.so module For
PostgreSQL, compile PHP using
--with-pgsql, or install the pgsql.so module For SQLite, compile PHP using
--with-pdo_sqlite, or install the pdo_sqlite.so module For MSSQL,
compile PHP using
--with-mssql_not_ready, or install the mssql_not_ready.so module For DB2,
compile PHP using --with-ibm_db2, or
install the ibm_db2.so module For
Oracle, compile PHP using --with-oci8,
or install the oci8.so module
Look in /php_install_dir/extensions. There should be a file named "php_mysql.dll". If so, enable it in php.ini. If not, download the dll, copy it to the extension dir and enable in php.ini. Remember to restart Apache.
See this page for more info (make sure you read the comments).
Changed this in php.ini. Shouldn't the installer have done this for a Windows installation?
; enable_dl = Off
; CHANGED - This is necessary to enable dynamic loading of Windows .dll modules
; The immediate problem was that PHP could not find a database driver for MySQL
enable_dl = On
For PHP: 5.6.10 and MySQL: 5.0.24a
Go to the root folder of PHP installation
Find a file called php.ini-production
Save the file as php.ini
Edit the file and uncomment the following contents
;extension=php_mysqli.dll
;extension_dir = "ext"
and replace it with,
extension= php_mysqli.dll
extension_dir = "D:\Programs\php\ext”

installing php cURL on IIS

I cannot install PHP-CURL on IIS. I think I have tried everything.
My phpinfo() output does not list cURL as available.
I have C:\PHP in my path and working correctly.
I have edited the registry to read from C:\PHP\php.ini. phpinfo() output shows the correct .ini path loaded.
I have uncommented 'extension=php_curl.dll'
I have ssleay32.dll and libeay32.dll availble in C:\PHP
Windows Server 2003
IIS 6
PHP 5.2.4
Try running:
php-cgi.exe -v
and see if any errors come up.
Also make sure the php is correctly in your path by going to the command line and typing:
echo %PATH%
As well make sure the php_curl.dll is in the correct directory and that ssleay32.dll and libeay32.dll are the same versions.
If all else fails try reinstalling PHP as I remember there being some issues a while back with the Curl Module not working on 5.1.4.
As well someone else mentioned installing the thread safe PHP package versus the non-thread package resolving a similar issue.
Did you definitely put php_curl.dll in the directory that PHP reads extensions from? Are the file permissions on it ok? And the big question: where did you get the php_curl.dll from? If you got a precompiled one it might be compiled for a different version of PHP than you are running. Check your webserver logs and see what comes up from PHP when you restart the server/container/whatever.
