I have the latest version of Apache (Apache 2.4), latest version of PHP (PHP7), and latest version of MySQL (not sure the version but I have WorkBench version 6.3). In the past, when I checked if my PHP was working by this line of code <?php phpinfo(); ?> it would show that I have MySQL / mysqli installed and ready to go. But with PHP7 it shows mysqlnd.
I try using mysqli commands to check if I can connect to my database by mysqli_ping() and I also tried connecting to the database using server, user, pass. I keep getting errors such as Class mysqli not found. Or Call to undefined function mysqli_ping(). I've tried searching the net for some answers and All I could find was that I need to install MySQL (but a few sites said it was deprecated).
Am I able to get mysqli for PHP7? Or do I use mysqlnd? What is mysqlnd? Is it a new version of MySQL/mysqli?
Update 2020
For Windows 10 users I strongly recommend windows subsystem for linux (WSL 2) and setup your server there.
If you need php and mysql access in windows environment, then the fastest way is to install Wampserver. If you also need access to php through console then add php location (like C:\wamp64\bin\php\php7.4.11) to environment variables.
If that doesn't suit you and you need full setup always enabled on your system then follow install with choco.
To work properly with apache and load all needed extensions (including php_mysqli) you need ThreadSafe version of PHP, so make sure to download correct version or if you use Chocolatey to manage your windows applications, then just install php with this command:
choco install php --package-parameters='"/ThreadSafe "'.
This will install php in C:\tools\php72 directory, but you can overwrite it with another parameter:
choco install php --package-parameters='"/ThreadSafe ""/InstallDir:C:\PHP"""'.
The mysqlnd extension is part of PHP. It was developed as an alternative to bundling the libmysqlclient, because that library had license conditions that made it awkward to bundle with PHP.
You won't use mysqlnd directly. It's an internal library that is used by mysqli and pdo_mysql as a means to communicate with the MySQL Server.
As for mysqli, yes, it's available for PHP 7. I don't use Windows, but apparently not all extensions are enabled by default.
You probably need to edit your php.ini and uncomment the line
extension=ext_mysqli.dll
or whatever it is for that extension. It might already be in the file, but commented out. So go take a look and see.
Check if your system path environmental variable includes the PHP installation directory. That worked for me on with PHP 7.1 / Apache 2.4 / Windows Server 2016.

I'm just shifting from wamp to mamp on windows.
Through mamp every thing is working perfectly (WordPress or PHP Projects).
1) In cmd when I work with wp-cli.phar file, it's give me the following error
your php installation appears to be missing the mysql extension which is required by wordpress
I check the php.ini files, extension path is perfect, php_mysql.dll isn't here. then I change PHP version 5.6.13 here I have php_mysql.dll extension but problem is same.
2) Also set the environment variable C:\MAMP\bin\php\php7.0.0;
When I check PHP Variable Path with phpinfo(); path are
Why it show wamp and mamp both path ?
Both problem have relation with each other ?
The path variable holds the windows OS' path environment variable's contents. Apparently, you have multiple versions of php installed: v5.5 and v7.0 and MAMP uses v7.0.
If you check out mysql's documentation on mysql extension, you will see that:
This extension is deprecated as of PHP 5.5.0, and has been removed as of PHP 7.0.0. Instead, either the mysqli or PDO_MySQL extension should be used. See also the MySQL API Overview for further help while choosing a MySQL API.
So, if you want to keep using mysql extension, then you need to downgrade the php version you use.
The other option is to upgrade to at least wordpress v3.9 because it can use mysqli extension instead of mysql.
So I have a trouble here. Tried use mssql_connect() but interpeter says that function is undefinied. PHP.net advices this, but it suppports only older versions of PHP. Is it possible to connect to MS SQL Server database from PHP5.6? What extensions should I add, what functions can I use?
Configuration details: localhost, Apache 2.4, PHP 5.6, OS Windows 8.
You need to enable the MSSQL extension in the PHP.ini file.
If this extension is not installed, you need to install it in PHP.
Please tell your server details (OS/WebServer like apache nginx) so that I can explain in detail.
Use
<?php phpinfo();?>
to see what are available with your php installation. I advice you to use PDO instead of mysql_* functions. It supports several databases not only MSSQL or MySQL.
I'm using xampp-win32-1.8.3-1-VC11-installer and i enabled php_mssql.dll extension in php.ini by remove ;
I copy php_mssql.dll to xampp\php\ext
and ntwdblib.dll to xampp\apache\bin
i got 2 files above in old of xampp version.
But when i start my apache in xampp then i get
How to fix that thanks
It announced from php website http://php.net/manual/en/intro.mssql.php
These functions allow you to access MS SQL Server database.
This extension is not available anymore on Windows with PHP 5.3 or later.
SQLSRV, an alternative extension for MS SQL connectivity is available from Microsoft: ยป http://msdn.microsoft.com/en-us/sqlserver/ff657782.aspx.
Since XAMPP 1.8.0 its used PHP 5.4.4 and php_mssql.dll extension is not available anymore on windows with PHP 5.3 or later.
So you can't use this library to your new XAMPP although you get it from your old XAMPP.
You must use alternative extension to connect to MS SQL Server database like SQLSRV.

Your php version from XAMPP 1.8.3 is PHP 5.5.15, so you must use "php_sqlsrv_55_nts.dll" or "php_sqlsrv_55_ts.dll". Those files can be downloaded from http://www.microsoft.com/en-us/download/details.aspx?displaylang=en&id=20098`.
Note :: see also the information on Details section to help you choose file that you must download

http://php.net/manual/en/book.sqlsrv.php
Windows PHP extensions are neither forward nor backward compatible between second-level PHP versions. That means you cannot use a PHP 5.3 extension in PHP 5.4 and vice-versa.
As you're running XAMPP 1.8.3 and this is one of the first PHP bundles with the VC11-PHP5.5 builds you'll have to find a VC11-PHP5.5 compatible extension somewhere else.
I've just checked another WAMP bundle called EasyPHP, but they don't ship the MS SQL extension with their VC11-PHP5.5 bundle either.
I can't help with finding a compatible extension, though.
You could also build the extension yourself if that is an option for you.
I have shifted my CakePHP (2.3.1 stable version) site to Host-ed.me and I am getting PDO class not found error. How to enble PDO on Host-ed.me server. Any suggestion is highly appreciated.
I suggest to first compare your previous/local PHP configuration with the configuration on hosted.me.
You can do so by generating a phpinfo() report of both. be sure to remove the phpinfo page afterwards - having a publicly visible phpinfo page on your website is a major security risk.
Check if PDO is really not installed on the webserver, either via the phpinfo() report or via instructions found in this question; How to determine if PDO is enabled in PHP?
You may also check if hosted.me is not using an outdated version of php, otherwise you may run into other problems later on
If PDO is not installed and is required for your website (or the php version is too old), there's no other option than to contact the hosting provider and ask them if it is possible to have it installed or your website be hosted on a different server.
Finally, if these options do not give you a solution, find a better hosting provider that does have a decent PHP installation :)
Check out this blog for details.
Basically, you have to do the folllowing:
1. Check if PDO is installed (lookinto your phpinfo() output / write simple program)
2. Install PDO, using yum install php-pdo
Test again, using the above scripts and you should be good to go.
You just need to enable the PHP extensions:
pdo
pdo_sqlite
sqlite
or ask host to enable them
I have successfully configured php in IIS. sample php pages working fine. now i want to connect it to sql server i tried it by downloading a mssql .dll file in ext folder,I also tried by installing a extension for windows driver, then also it is not working. please help to sort out this issue. I am Using php5.3.19 for the same.
In order to use PHP 5.3 with SQL Server (2005 and above), you will need the Microsoft Drivers for PHP for SQL Server. There are two versions available: 2.0 and 3.0. 3.0 includes support for SQL Server 2012 and PHP 5.4.
You can find instructions for installing the dlls and interfacing with SQL Server in a TechNet article.
To install the extensions, you must move them into your ext folder and add a line to php.ini to load them, like the following:
extension=php_sqlsrv_53_nts_vc9.dll
Once this is done, restart the web server and load phpinfo in order to see if the extension has loaded. If it has loaded correctly, you should see a "sqlsrv" section in PHPInfo.
When the time comes for you to begin writing PHP that connects to SQL Server, make sure you have installed the native client. The current version is the SQL Server 2012 Native Client. References for the API are available on TechNet and PHP.net.
Finally, consider upgrading to PHP 5.4. The 3.0 versions of the drivers support 5.4 but the 2.0 versions do not; if you cannot install 3.0 on your system, you can find a 5.4-compatible version of the DLL (sqlsrv-5.4-nts-snap.zip or
sqlsrv-5.4-ts-snap.zip) on PHP.net. I have had good results with these versions.
