phar Class not found - php

I am trying of install the dependency manager for php "composer", but "composer" needs the extension "phar". I've realized php6 comes with phar by default, but is disabled and not necessary in order to execute "phar" files.
When I try execute "composer.phar" (in the cmd: php composer.phar) it throws the error:
Fatal error: Class 'Phar' not found in composer.phar on line 13.
If I try to execute the Composer installer, "installer.php" (in the cmd: php installer.php) throws this error:
Some settings on you machine make composer unable to work properly. Make sure that you fix the issues listed below and run this script again:
The phar extension is missing. How can I fix this?
Should I install it or recompile php without --disable-phar I am using appserv 2.6.4 (apache 2.2, php6, mysql 4).

You really shouldn't use cutting edge theoretical software. PHP6 doesn't actually exist. Downgrading to a more realistic version of appserv would solve your problem. But if you insist on using 2.6.4, you should do the following:
check that phar.so exists in the php extensions directory. If not, you need to install that extension.
if it exists, check if it's listed in php.ini as extension=phar.so. If it's not, add that line.
if it is, check that it's listed in the php.ini that command line PHP uses, too. Command line PHP and web PHP sometimes use different php.ini files, and while one might have phar.so activated, the other might not.

Error when switching to Luasandbox: Scribunto_LuaInterpreterNotFoundError

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?

Trouble installing composer for PHP 7 on windows to get PHPmailer

I want to add phpmail to my php Server. The server is a windows machine. I searched for it and found out that the best way to install it is with composer. I'm having trouble getting composer to install due to php.ini issues.
I am getting the following error:
*The PHP exe file you specified did not run correctly:
C:\php\php.exe
The php.ini used by your command-line PHP is: C:\Windows\php.ini
A setting in your php.ini could be causing the problem: Either the 'extension_dir' value is incorrect or the dll does not exist.
Program Output:
PHP Warning: PHP Startup: Unable to load dynamic library 'c:\php\ext\pdo_odbc' - The specified module could not be found.
in Unknown on line 0*
I tried searching the net for pdo_odbc but am not sure what I'm looking for. where can I get the missing dll?
I finally got composer to install. I had to first, rename the ODBC DLL from PHP_pdo_odbc.dll to pdo_odbc.dll. Then I got a message about SSL not being enabled. I first had to enable it in php.ini. Again I had to rename the DLL for SSL from PHP_openssl.dll to openssl.dll. Then Composer installed. Why did PHP install with the DLL's named differently than composer was expecting? Or is this a composer issue or the fact that it's PHP on windows? From there I installed PHPmailer and sent my first piece of mail. This is so much more complicated than coding in .Net

PHP Startup: Unable to load dynamic library php_msgpack_serialize

PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/20131226/memcached.so' - /usr/lib/php/20131226/memcached.so: undefined symbol: php_msgpack_serialize in Unknown on line 0
Earlier today, I enabled forwarding of messages to root#localhost on my server to beam back to my personal email.
I have been receiving the above error message at 30 minutes intervals since. Of course, I checked and there's a PHP session cleaning script attached to cron to run at 30 minutes interval.
I have been searching around but couldn't find any specific solution.
My setup:
memcached 1.4.25
PHP 7.0
nginx/1.10.0
mysql Ver 14.14 Distrib 5.7.13
Ubuntu Server LTS 16.04
The closest I found to my issue above was this: http://community.rtcamp.com/t/php-warning-error-php-msgpack-serialize/6262 but there's no answer on that thread.
First you need to work out which PHP ini files are being loaded. From command line you can run php --ini. Technically apache/nginx can be running a different version, and you can look up using phpinfo(); exit(); test script if you want to view that one instead. As you're using cron, you're using the command line version anyway.
In one of these files you will find a line similar to:
extension="memcache.so"
If you don't need this extension at all, then just comment it out by prepending it with a ;:
;extension="memcache.so"
If you DO need the extension then it sounds like you need to rebuild this module. The easiest way is using PECL.
pecl install memcache
You might need to follow some instructions whilst running the install. Once it's done, you should be able to run php -v and it shouldn't output the same warning. If this has worked and you just see the php versions, you should restart nginx (if you need it on the website, the command line one should work instantly). :
sudo service nginx restart
I guess you can get a help from a similar topic on the site here.
But briefly, one of your extensions is loading memcache and the path in that is not correct.
You should find it in your php.ini and fix the path manually.
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.
Check if msgpack extension is installed and enabled (php -i | grep msgpack).
It seems that PHP in Ubuntu is compiled with it by default.
If it's installed and enabled, then check you memcached extension. Maybe you are using it from a previous installation or something similar.
tl;dr: I eventually had to clear everything PHP that is less than php7.0 from my server manually, along with their related cron jobs.
Long story:
Going through my running process (ps -aux | grep 'php'), I realized php5 is still in there running. Everything on my server uses PHP7, so that lingering process was redundant, plus there was a cron job that runs a session cleaning job on the php5 somewhere, using a script which goes looking for the so-called missing Memcached file.
After removing all phps that are less than php7 from system via apt, I also went in to delete all the existing folders that are less than php7 in /usr/lib/php5 and or /usr/lib/php/ along with their cron related jobs found in /etc/cron.d/php5 and or /etc/cron.d/php/
No more whining warnings from PHP session cleaning about memcache
I was getting a similar error with memcache.so and I noticed there was a new version of memcache that was installed the moment the system ran 'pecl install memcache' (automatically that updated to the latest version). The new version caused that error so I had to change the version 1 version lower to pecl install memcache-4.0.5.2 and it worked. Thanks #Farkie for that insight, that's when I realized that there was a new version that just came out a few days ago and that was it!
Just install msgpack extension and the error message should disappear:
apt install php-msgpack
You might also be missing igbinary extension:
apt install php-igbinary

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.
