PHP Warning: PHP Startup: Unable to load dynamic
when I check the php version, I am prompted for an error
PHP Warning: PHP Startup: Unable to load dynamic library "bz2.so" (tried: / usr/lib/php/20170718/bz2.so (/ usr/lib/php/20170718/bz2.so: cannot open shared object file: No such file or directory),) / usr/lib/php/20170718/bz2.so.so (/ usr/lib/php/20170718/bz2.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

is so urgent that no solution can be found on the Internet. The project just crashed there, turn to your friends
so extension file cannot be found, which means the path is wrong. Confirm where the specific path is. If you don't know, you can see where the extension file is. Change it to the same one and try again.
Sometimes people here are not as they could be.
For whatever reason, your php.ini is mis-configured.
One thing to note that all those missing files are actually Windows files ( .dll) on Linux these would likely be .so files. I'm assuming your hosting on a Linux server.
First find your php.ini file. If you have command line access via SSH, you can try running:
php-- ini
if not you make a simple script, call it test.php like so:
phpinfo ();
? >
Upload the file and run it, something like:
http://www.yoursite.com/test.php
Among the information provided will be the path to php.ini
Once you find it, one option is to edit it and comment out all those extensions, by putting a ";" in front of the line.
Another option is to check if the *. So files exist. Look for them under / usr/lib/php. If they exist, edit your php.ini file to have all those extension end in .so instead of .dll
Finally, if they don't exist, you could install them by using apt-get or yum. An example:
sudo apt-get install php-mbstring
