Linux operation and maintenance - PHP encounters problems when installing extensions

Install the phalcon extension in php. After the compilation is successful, I first addedextension=phalcon.soin php.ini, but when using php -m, there is a php warning error, and at the same time, an error is reported when php -v , then deletedextension=phalcon.soin php.ini, and added the filephalcon.iniin /etc/php.d. In both cases, the same error was reported

php -v

php -m

service php-fpm restart

/usr/lib/php/modules/ 

/etc/php.d

No need to add extension=phalcon.so in php.ini.

Just follow the documentation. https://docs.phalconphp.com/e...

Since the linux platform is used

Now you can use apt-get or yum to install

Configure the source:

curl -s https://packagecloud.io/install/repositories/phalcon/stable/script.deb.sh | sudo bash 

Then install

sudo apt-get install php7.0-phalcon 

But I’m usually used to compiling the source code for installation, which is what the documentation says.

The problem seems to be that the compilation is not completed. Check to see if the compilation in the specific directory has been completed, and the compilation steps

php -v is running php-cli

I want to know which calling method of your /etc/php.d? cli? fpm?

Is mods-available modified correctly?

Visual inspection indicates that the PDO extension is not installed. phalcon relies on PDO

make&&make install error is obvious. The .so library file is not placed in the extension directory
