Error when switching to Luasandbox: Scribunto_LuaInterpreterNotFoundError - php

I installed a new Instance of MediaWiki 1.39 on a Debian 11 server with PHP 8.2.2. I installed the Scribunto extension (and its dependencies) with Luastandalone binaries at first and it worked. A script that we would like to use seems to meant for Luasandbox, though, so I wanted to switch to Luasandbox.
I followed the instructions from https://www.mediawiki.org/wiki/Extension:Scribunto and https://www.mediawiki.org/wiki/LuaSandbox. Because the prepackaged installation with sudo apt install php-luasandbox only seems to be able to get packages for php7.4 I used the manual installation.
Following the installation php -ini lists:
luasandbox
luasandbox support => enabled
and php -m contains:
luasandbox
In the LocalSettings.php I removed the other Scribunto entries and added
$wgScribuntoDefaultEngine = 'luasandbox';
instead.
The Special:Version page continued to list Scribunto as an active extension but when a script is invoked, it failes with an Internal Error:
Fatal exception of type "Scribunto_LuaInterpreterNotFoundError"
Does anybody know why this happens or have any pointers on how to diagnose the issue further? How can I make sure Scribunto looks in the right place? (i.e. the location where I downloaded and compiled the luasandbox files as described in the installation instructions) Are there any additional log files I could check?

Install PHP 7.0 Internationalization extension (Intl) on XAMPP on Mac

I followed the instructions outlined here:
Install PHP Internationalization extension (Intl) on XAMPP on Mac
Ran sudo pecl install intl
selected the correct files from the Cellar
then this error happened:
/private/tmp/pear/temp/intl/intl_error.h:24:10: fatal error:
'ext/standard/php_smart_str.h' file not found
include
^ 1 error generated. make: *** [php_intl.lo] Error 1 ERROR: `make' failed
No matter, did some research and found out that PHP 7.0.8 deprecated php.smart_str.h to php.smart_string.h
So given my scant knowledge of C++ I copied smart_string.h to smart_str.h and renamed all the headers from STRING to string.....
re-ran pecl -no luck....more errors......without knowing where the .c files are and remaking php (not really interested in going that far) since anyway I'm using XAMPP so that ended that option.
I have php 5.5 on my mac, deep in the usr/local/bin folder
so next step was to get pecl to use those files and generate an intl.so file....
Did that....I have the intl.so file so put it in the 'extensions' folder in XAMPP (for reference: /Applications/XAMPP/xamppfiles/lib/php/extensions/no-debug-non-zts-20151012)
Ran php and came up with this error:
Warning: PHP Startup: Unable to load dynamic library
'/Applications/XAMPP/xamppfiles/lib/php/extensions/no-debug-non-zts-20151012/intl.so'
- dlopen(/Applications/XAMPP/xamppfiles/lib/php/extensions/no-debug-non-zts-20151012/intl.so,
9): Symbol not found: _zval_used_for_init Referenced from:
/Applications/XAMPP/xamppfiles/lib/php/extensions/no-debug-non-zts-20151012/intl.so
Expected in: flat namespace in
/Applications/XAMPP/xamppfiles/lib/php/extensions/no-debug-non-zts-20151012/intl.so
in Unknown on line 0
I imagine it has to do with different versions?
In any case I can't get pecl to install intl without a make error in PHP 7.0.8 on XAMPP. There is no documentation on this and you'd think that if you deprecate a header.h file you'd update all extensions?
Install intl.so in PHP 7 seems impossible?
After a lot of research I was finally able to resolve this. Detailed steps here:
before you begin, check which php path is set. it should be /Applications/XAMPP/xamppfiles/bin/php. If not you can change it by PATH="/Applications/XAMPP/xamppfiles/bin:${PATH}". more detail here
Overall idea is to build the intl-extension from PHP source code on your own. Before you begin make sure you have installed Xcode. Also, install the latest version of autoconf. this might help:
brew install autoconf
Next download the version of PHP you use in XAMPP from php.net. I am using 7.1.18. This version worked for me: php-7.1.31, I’m guessing if you follow the steps it might work for 7.0 or 7.2 as well. Do let me know if it does or doesnt, I’ll update this post. Do not use PHP 7.3 for Magento 2.3.0, it is not supported.
Extract the tar.gz file using (I extracted it inside ~/Downloads/ folder )
tar -xzvf php-7.1.31.tar.gz
cd into the extracted folder
cd php-7.1.31
change to subfolder ext/intl
cd ext/intl/
Run these commands to build the extension
/Applications/XAMPP/bin/phpize
./configure --enable-intl --with-php-config=/Applications/XAMPP/bin/php-config --with-icu-dir=/Applications/XAMPP/xamppfiles/
make
sudo make install
you can now delete all files you downloaded and also the extracted folders.
Open /Applications/XAMPP/xamppfiles/etc/php.ini , and add extension=intl.so
Restart your Apache using XAMPP GUI and it should work.
So far, it seems that extension intl.so for php is bundled with php
and should be compiled with php (intl --enabled). XAMPP does not support this (as of Oct 2016), MAMP does. I do not know about other distros. However, if you're willing to recompile PHP 7, it's worth it just to do that and enable it during compiling.
So....I ran with MAMP. Then I decided that I would simply install apache 2.4 and php 7 and Mysql without the stack and the junk that comes with MAMP or XAMPP and everything works like a charm... so if you need to use CakePHP or intl support etc... just drop XAMPP/MAMP and go with a standard install. I used homebrew (MacOS) and everything is working fine.
Update: As regards Windows, XAMPP does not default it, but you can add the module (dll) in php.ini and works like a charm
The error means that XAMPP doesn't have PHP compiled with intl. You may try:
pecl install intl
but probably it won't work as well.
See: PHP Bug #72879 Pecl install intl make error with PHP 7.0.8.
As for the workaround, try installing memcached extension instead of memcache, e.g.
pecl install memcached
Note: It also requires libmemcached package/library to be installed beforehand. For macOS, install via: brew install libmemcached.
If you wanna try without homebrew, with native apache and php, look at my aswer here: https://stackoverflow.com/a/55131868/3692846

Including the SVN class in a PHP Project

So this probably has a simple answer, but I'm not finding it anywhere.
I have the following code:
function getSVN(){
$svn = new SVN;
$log = $svn->log('https://svn.repo/trunk/', SVN::HEAD);
}
Not surprisingly, I get the following error:
Fatal error: Class 'SVN' not found
So I tried to include it using:
use SVN;
But I got:
Warning: The use statement with non-compound name 'SVN' has no effect
What's the proper way to include PHP's SVN class?
The SVN PHP client requires an additional PHP extension to be loaded.
http://php.net/manual/en/svn.installation.php has some general installation instructions but the real gold is in the comments.
Aptitude systems (incl. Ubuntu)
sudo apt-get php5-svn
Aptitude tends to resolve dependencies so we're good in that front.
Yellowdog Updater, Modified (yum) systems
yum install subversion subversion-devel neon neon-devel
pecl install svn
Windows
Download the DLL if you can find one.
Otherwise compile from source.
Works on all systems
Compile from source
Following all this you need to ensure that either:
1) There is a relevant entry in php.ini which enables this extension: e.g. extension=svn.so (or DLL)
2) There is a relevant configuration .ini file which is included with php (the path where this should be is stated in phpinfo();)
In any case the extension needs to show up in the php -m list
Although this question is nearly 3 years old as I post this, I would like to contribute my solution to possibly help others who have encountered errors on Redhat style machines.
I was able to successfully install it via RPM package install. The links below may help you, depending on OS and PHP version.
www.rpmfind.net
centos.pkgs.org
I simply followed the instructions from CentOS packages and the php pecl-svn extension installed with no issues on the Redhat 6.9 PHP 5.6 server. Hopefully the same works for you. Best of luck.

How do I solve this PHP-PEAR error / install PEAR on Fedora?

I'm trying to save an old, failing web-server setup consisting of Fedora, PHP, PEAR, and Oracle.
With some difficulty (I'm very new to all four), I've been able to set up something similar on a newer system. I used Fedora 19, PHP 5.5.4 (with Apache 2.4.6), and Oracle 11g.
That just leaves PEAR.
Now, from what I understand, PEAR is some PHP code, like a library, which PHP Web Applications can use to save time from having to code them again - database connection, for example.
But I don't know what to do with it, or even how to get it. Copy paste from my old system? Download using the CLI using yum? Are there packages I need to be aware of, or is it just a one download-one install thing?
For instance, a basic PHP webpage with the following code:
<?php
phpinfo();
?>
works fine on the new server setup, so I'm assured that everything else is working. But when I try to load the PHP files from the other server, it returns an Internal Server Error. I checked the error_log files under /etc/httpd/logs, and most of the errors appear as below:
PHP Fatal error: require_once(): Failed opening required 'MDB2.php' (include_path='.:/usr/share/pear:/usr/share/php') in /var/www/html/hrweb/includes/functions.php on line 4
EDIT:
According to the PEAR Website, PEAR is included upon the installation of PHP, though not all modules / packages are there. Typing in the command pear in the CLI does confirm it is installed, though it does not help the issue.
I got the MDB2 package via pear install MDB2, though apparently, MDB2_Driver_oci8 is required. Whenever I try to download that, I get the following:
"MDB2_Driver_oci8" version "1.4.1" does not have REST XML available
In addition to this, I also tried to download OLE, which gets me the following:
No releases available for package "pear.php.net/OLE"
This was also previously the error of trying to download MDB2_Driver_oci8.
Thanks.
You have to install the (surprise!) MDB2 package to get MDB2.php:
$ pear install mdb2
and the adapter of your choice:
$ pear install mdb2_driver_mysql-beta
Then make sure the PEAR php directory is in your include path - see the PEAR manual.
"MDB2_Driver_oci8" version "1.4.1" does not have REST XML available
try to install the beta version:
$ pear install mdb2_driver_oci8-beta
No releases available for package "pear.php.net/OLE"
You're trying to install the stable version, but OLE does not have any stable version (yet): http://pear.php.net/package/OLE/download
Append either -alpha or -beta after OLE:
$ pear install OLE-beta

CentOS - Mongo class not found in PHP

I need the MongoDB PHP driver on my CentOS 5.4 machine. My PHP version is 5.1.6. I downloaded the RPM and installed it. That created several files in /usr/bin directory. I copied
/usr/bin/mongo
to
/usr/lib/php/modules
which was what extension_dir showed on doing phpinfo();.
I also added
extension=mongo.so
in /etc/php.ini.
However on executing my PHP script, i still get
Mongo class not found.
What's going wrong here ?
Also, my phpinfo() shows PHP version 5.1.6 whereas running PHP from command line shows 5.3.3. Could anything be wrong with that ?
Thanks in advance.
You're saying your webserver and command line PHP report different versions. These are going to be installed in different locations, and their extensions are API incompatible with each other.
When you installed the php_mongo extension, it may have used the command line php to determine the directory to install the extension to.
Make sure you have the correct php_mongo for the php version of your webserver, and it is in the correct extensions directory. (get the directory from the php.ini returned by phpinfo())
I hope you realise PHP 5.1 is also many years out of date. Unless you have a specific reason to use a version that old, you should also look at upgrading to a more recent version.
Edit:
Just read your comment "I must also mention that /usr/bin/mongo is a binary executable file but its not having a .so extension. Im copying it as is to /usr/lib/php/modules"
No no no! :)
This is the mongo command line client. This is not the PHP extension!
You can run a find /* -name "mongo.so" to see where the installer put the file, this will probably also give you an indication of which version of PHP it was installed for.
It looks as though you are confusing the RPM-packages for the MongoDB server with the requirements to install the MongoDB PHP driver. The PHP driver provides access to the server from your PHP applications, and does not install any command line tools.
restart httpd !
yum service httpd restart

Compiling a PHP extension as non-thread-safe

I am trying to compile the imagemagick (imagick) extension to use in a non-thread-safe environment on windows.
I am using PHP 5.3.10 and have set up Visual C++ express as my compiling environment.
The problem is that I am using a non-thread-safe version of PHP as a FCGI module in Apache 2.2.
Thus, my PHP is supplied with a php5.lib and not a php5ts.lib. I believe this is the reason why I am getting these errors:
imagick.obj : error LNK2019: unresolved external symbol __imp__tsrm_mutex_alloc referenced in function _zm_startup_imagick
I have only ever built and compiled things on linux, so am not too sure how to do this on a windows environment.
How can I compile the extension so that it is non-thread-safe?
I downloaded the threadsafe binary of PHP 5.3.10 to get a copy of php5ts.lib. I was then able to compile the extension.
I am guessing that setting the ZTS preprocessor directive to either 1 or 0 would cause the extension to compile as either threadsafe or non-thread-safe. (Not too sure about this, so if someone could let me know if this is correct or not, it would be much appreciated. :) )
I then set up a virtual machine running Windows 7 and installed the latest version of WAMP. Reason being that it used a threadsafe version of PHP.
I placed the dll in the ext folder in the PHP installation and enabled it in php.ini. However, even after trying both the ts and nts version in WAMP, I would get:
PHP Warning: PHP Startup: Unable to load dynamic library 'c:/wamp/bin/php/php5.3.10/ext/imagick.dll' - The specified module could not be found.
in Unknown on line 0
But the thing is that c:/wamp/bin/php/php5.3.10/ext/imagick.dll' does exist, and yes I have checked this a lot of times.
I then downgraded ImageMagick to 6.6.2-10-Q16, but still see the same problem.
The same issue occurs on my dev machine running a nts version of PHP 5.3.10 on Apache 2.2 (all installed manually).
Looks like I could be wrong regarding the ZTS preprocessor. If I set ZTS=0 and compile, using dependency walker on the compiled dll still shows that it requires php5ts.dll which is only present on threadsafe versions of PHP.
I did more tinkering with dependency walker and found that I had to statistically link to msvc100d.dll. I then removed ZTS in the preprocessor definition and was able to compile using php5.lib instead of php5ts.dll. I think this should get me a non-ts dll.
However, when loading the extension, I am still getting:
PHP Warning: PHP Startup: Invalid library (maybe not a PHP library) 'imagick.dll' in Unknown on line 0
And errors from dependency walker:
Error: At least one module has an unresolved import due to a missing export function in an implicitly dependent module.
Error: Modules with different CPU types were found.
Warning: At least one delay-load dependency module was not found.
Warning: At least one module has an unresolved import due to a missing export function in a delay-load dependent module.
Installed visual c++ express 2008 and compiled using platform toolkit v90, but still facing the same issues.
Any tips appreciated :)
Solution Found! See my answer.
Got it! I hope this can help those compiling php extensions on windows in the future. What I have done is based on: https://wiki.php.net/internals/windows/stepbystepbuild
Note: I read an answer on this site that said compiling PHP extensions by itself on windows is unsupported. Based on my experiments yesterday, it seems to be a lot of work as well, so I am using the PHP build process.
The best way is to use the PHP build process.
Install Visual C++ Express 2008 (any version will do, but express is free) and Windows SDK 6.1 (note that we want the 6.1 version not anything older or newer).
Install the SVN client tools if you haven't done so and restart for your PATH variable to take effect.
Get the PHP SDK binary tools and extract it to C:\php-sdk.
Start the CMD Shell under Microsoft Windows SDK v6.1 in your start menu and run cd C:\php-sdk.
Run setenv /x86 /xp /release this creates a 32-bit release. You can use /x64 to build a 64-bit release (I have not tried this).
run bin\phpsdk_setvars.bat
run bin\phpsdk_buildtree.bat php53dev
Download the PHP source code and extract it to C:\php-sdk\php53dev\vc9\x86 so that you end up with C:\php-sdk\php53dev\vc9\x86\php5.3-xyz
Download the latest deps and extract everything to C:\php-sdk\php53dev\vc9\x86. You may be prompted to overwrite any existing folders, so press yes.
run cd C:\php-sdk\php53dev\vc9\x86
Check out the latest version of your extension from the svn repository: svn co http://svn.php.net/repository/pecl/imagick/trunk pecl/imagick I am checking out imagick here.
Install any dependencies. In my case, I need to install ImageMagick, so I downloaded the latest recommended windows binary. You will need to restart after installation to update your PATH variable, but you can do this after you have compiled. Make sure you install the C/C++ headers and includes as well.
Copy the contents of the includes directory from the ImageMagick install directory to C:\php-sdk\php53dev\vc9\x86\deps\include.
Copy the contents of the lib directory from the ImageMagick install directory to C:\php-sdk\php53dev\vc9\x86\deps\lib
Now, let's build: run cd C:\php-sdk\php53dev\vc9\x86\php5.3-xyz then buildconf then configure --help. Look at the help properly. It will show you all config flags and any avaliable extensions to enabled. In my case, since I added imagick, I had an option called --with-imagick
Run config: configure --enable-cli --with-imagick=shared --disable-zts If you want to build a non-thread-safe binary use --disable-zts, otherwise remove that configuration flag. I am not sure why, but sometimes extensions use the --with-myextension flag and sometimes --enable-myextension, so check configure --help for the flag to use. If you add =shared after the extension flag, it will be compiled as a separate DLL, which si what we want.
Compile: run nmake then nmake snap.
Done :) Check C:\php-sdk\php53dev\vc9\x86\php-5.3.10\Release (non-thread-safe) or C:\php-sdk\php53dev\vc9\x86\php-5.3.10\Release_TS (thread-safe). Your compiled binaries should be in there. The compiled extensions (pecl), should be in a ZIP file similiar to pecl-5.3.10-nts-Win32-VC9-x86.zip. Open this file and extract the extensio DLL to your ext folder in your PHP installation.
Enable the PHP extension and restart your webserver. Run phpinfo() and check that the extension is enabled.
If the extension does not work properly, make sure you reboot to update your PATH variable. In my case, I need to have the imagemagick install directory in my PATH variable.
???
Profit!
Is there a reason you need to compile? Why not download? It's usually much simpler/quicker on Windows.
