Unable to install php-mysqli on PHP7

I have installed PHP 7, mysql5.7, Apache2.2, CentOS6.

And I'm installing CodeIgniter3.0.6.

When I use database connection, error occured and said

A PHP Error was encountered

Severity: Core Warning

Message: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/php_mysqli.so' - /usr/lib64/php/modules/php_mysqli.so: cannot open shared object file: No such file or directory

Filename: Unknown

Line Number: 0

Of course there are no files in '/usr/lib64/php/modules/php_mysqli.so', but I don't know how to install mysqli.so.

I tried 

yum install php-mysql

but

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

and it didn't work.

when I execute yum install php7.0-mysql or yum install php70w-mysql command,

No package php7.0-mysql available.
Error: Nothing to do

I don't know what to do at all.

Please remind that the mysql extension is deprecated and doesn't exists anymore with PHP 7.

The php-mysqlnd package provides only the mysqli and pdo_mysql extensions.

The php-pecl-mysql is also available, build from a git snapshot, provided for compatibility for legacy applications, but is not supported.

From the original question:

Installed: php-common-7.0.4-1.el6.remi.x86_64 (@remi-php70)

You have php 7.0.4 installed from remi-php70, but the repository is not enabled. You need to enabled it, so yum will find the right package matching the installed version.

From the Configuration Wizard instructions:

yum install yum-utils
yum-config-manager --enable remi-php70
yum install php-mysqlnd

Notice: the correct command to install an "foo" extension is yum install php-foo, so "yum install php-mysql" will install the package which provides the mysql extension (so php-pecl-mysql), "yum install php-mysqli" will install the packages which provides the mysqli extension (so php-mysqlnd).

For PHP7, on CentOS / RHEL:

yum install php70w-mysql

if you use the Remi repository

yum install php70-php-mysqlnd

for Ubuntu:

apt-get install php7.0-mysql
