Installing PHP SDK Couchbase error - php

I'm trying to install the PHP SDK for my Couchbase cluster and everything during installation finishes without a hitch, but when I run php -i in the terminal I get the following error:
PHP Warning: PHP Startup: Unable to load dynamic library
'/usr/lib/php5/20121212/couchbase.so' -
/usr/lib/php5/20121212/couchbase.so: undefined symbol:
php_json_decode_ex in Unknown on line 0
I don't understand why the couchbase extension won't load.
My setup is:
Ubuntu Server 14.04
Couchbase Server Enterprise 4.5.1
I followed this guide for setting up PHP SDK:
Link to PHP SDK installation guide

Enable extension=json.so in your php.ini if it is not enabled. If it is, enable the couchbase extension after the json extension.
As said in the couchbase php sdk documentation
The Couchbase SDK depends on the JSON PHP extension, so make sure that load order is correct. For example, if your distribution has just a single php.ini file, just insert the line after extension=json.so. If your distribution uses a conf.d-style, name the file with the Couchbase SDK ini so that it will be alphabetically ordered after the JSON extension.

Not able to load php_grpc.dll for php 5.6 in xampp for windows

I am trying to use google cloud php sdk to fetch from google bigtable and found that it requires grpc to be enabled.
So i tried installing grpc on my xampp by downloading dll file from https://pecl.php.net/package/gRPC
I am running PHP version 5.6 on using xampp on my windows machine
I also updated my php.ini file by adding below
extension=php_grpc.dll
I restarted apache and printing phpinfo but i am not able to find grpc module loaded.
I also checked the list of extensions loaded by running php -m command and i get below error.
PHP Warning: PHP Startup: Unable to load dynamic library 'C:\xampp\php\ext\php_grpc.dll' - The specified module could not be found.
in Unknown on line 0
Warning: PHP Startup: Unable to load dynamic library 'C:\xampp\php\ext\php_grpc.dll' - The specified module could not be found.
in Unknown on line 0
Can anyone provide me a solution?
I was facing the same issue when installing the Google Ads PHP library on WAMP Server. I solved it downloading a different gRPC version
https://windows.php.net/downloads/pecl/releases/grpc/1.17.0/
Extacted the file and copied on the extensions directory of WAMP and on the php.ini just add the next line
extension=grpc
Restart apache and php. Hope it helps

PHP ZMQ Extension: Unable to load dynamic library

I'm working on Wampserver on Windows 10.
I'm using an extension called ZMQ. I downloaded the DLLS from:
https://pecl.php.net/package/zmq/1.1.3/windows
I previously used the version of the extension for PHP 5.6 and it worked. The extension however had a bug, so I decided to upgrade my php version to 7.0.4 and try the new version of the extension.
The extension was successfully installed and it appears in the phpinfo(), but when I try to run "php -v" from the command line (or the CLI service that uses the extension), I get the following error: "Warning: PHP Startup: Unable to load dynamic library 'D:/wamp64/bin/php/php7.0.4/ext/php_zmq.dll' - The specified module could not be found.
in Unknown on line 0"
The weird thing is the file "php_zmq.dll" actually exists in the specified path.
Important note: I have the line "extension=php_zmq.dll" in both my "D:\wamp64\bin\apache\apache2.4.18\bin\php.ini" and my "D:\wamp64\bin\php\php7.0.4\php.ini" (which to my understanding is used by the CLI). I can't remove either of those lines because then the extension is removed, or it doesn't work in the CLI.
I had the same problem. using PHP 7.0 x64 TS. I used the exact dll from pecl but same error. all my other extensions load fine and are in the same directory
i followed all instructions on https://superuser.com/questions/585291/installing-zeromq-on-windows-7-wamp-server.
the main updates would be to do the following:
copy libzmq.dll and libsodium.dll to php root dir. (both are found in the pecl zip files.

using V8js in your MAC?

My idea is to use reactjs with serverside rendering in PHP. I run and install with success php55-v8js using homebrew. the path of installation is /usr/local/Cellar/php55-v8js/0.4.0_2
in my application I tried to use V8 but with no success. the message displayed is:
Fatal error: Class 'V8Js' not found in
/Applications/AMPPS/www/phpreact/index.php on line 14.
on line 14 the following code is displayed: $v8 = new V8Js();
my main question is: do we have to call v8 through a require_once/file_get_contents->toPath or similar? or homebrew installation make v8 available globally on the OS system?
If you installed the V8 PECL extension correctly, you also need to turn on the extension in your .ini file and restart your PHP server.

pecl - gearman - Unable to load dynamic library?

I'm setting up the default instance for a new Amazon Elastic Beanstalk cluster however I'm having issues installing the gearman php client via pecl.
I ran pecl install mongo without any issues, but after I run pecl install gearman it gives the following error:
[root#ip ~]# php
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/gearman.so' - libgearman.so.8: cannot open shared object file: No such file or directory in Unknown on line 0
I do have gearmand installed, just the php client is giving me trouble. The php module gearman.so is in the "/usr/lib64/php/modules/" folder too.
Anyone have any idea why this might be happening?
Unfortunately gearman is a bit more complicated to install. You will need to download and compile the gearman server even if you don't intend to use your current server for gearman. It provides the library that you are missing.
If you look at the error message its missing libgearman.so.8 not gearman.so

Differences between PHP 5.2.x and 5.3.x with respect to the SOAP library

I have developed a PHP site using PHP 5.3.4 and deployed it to a server that has PHP 5.2.6 installed. I am not doing anything fancy; in fact, the only major library I am using is PHP's native SOAP library.
However, when I test my deployed site, I get the error:
Fatal error: Class 'SoapClient' not found in (path) on line 20
Are there any major differences between PHP 5.2.x and 5.3.x with respect to the SOAP library? I have already changed the configuration files. (Well, actually I told the sysadmin to do it, because I don't have permission to do so.) And I get the same error. Any ideas?
EDIT: More information...
I'm deploying my site to a Windows server.
The server has AppServ installed.
For some reason I don't understand, PHP's configuration file is C:\Windows\php.ini instead of PHP_DIR\php.ini.
I dont think soap is installed on the server try
sudo aptitude install php-soap
change the following line in php.ini:
;extension=php_soap.dll // before
extension=php_soap.dll // after
this enables the soap extension since PHP 5.0
