[SOLVED]Some PHP Problems about mysqli and pdo

jojo06 · 2024-01-04 12:54:40

In phpinfo it shows that there is no PDO support / driver. I cannot use PDO connection on localhost. I cannot debug in VSC.
I activated extension mysqli and everything like that (by deleting ; semicolon at the beginning). But it still shows problems.

I don't know if it is due to the updates, if I am not mistaken, I noticed something like this: When I opened the php.ini file again and looked at it, some extensions were put back in the comment line with a semicolon. mysqli, pdo and anything similar to these names, I removed the ; at the beginning of all of them.

Current:

extension=mysqli
extension=mysql
extension=mysqli.so
extension=pdo_dblib
extension=pdo_mysql
extension=pdo.so
extension=pdo_odbc
extension=pdo_pgsql
extension=pdo_sqlite
extension=/usr/lib/php/modules/mysqli.so

As far as I can tell from the descriptions, I didn't open them because it might be a problem and I don't need to, but as you can see, everything else is very active and installed. 

;mysqli.rollback_on_cached_plink = Off
;mysqlnd.debug =
;mysqlnd.log_mask = 0
;mysqlnd.mempool_default_size = 16000
;mysqlnd.net_cmd_bufer_size = 2048
;mysqlnd.net_read_buffer_size = 32768
;mysqlnd.net_read_timeout = 31536000
;mysqlnd.sha256_server_public_key =

php --ini

What's the output of `pacman -Qi php` and `pacman -Qkk php`?

Oh - I misunderstood your first post. In your code snippet you listed two `ls` commands that appeared to not have any output, but in reality you just showed the output of the commands after both of them (i.e., out of order / out of context). You may want to fix that as it's confusing.

Php is trying to load modules from the wrong location - it likely is related to /etc/php/conf.d/igbinary.ini or /etc/php/conf.d/redis.ini. Please post the output of `pacman -Qkk php-igbinary php-redis` and post or link to the full content of your php.ini (and those other inis if they are changed from the stock default).

pacman -Qkk php-igbinary php-redis

php-redis: 17 total files, 0 altered files

I only know/remember the php.ini, shouldnt be anyother. Can you please mention some ?
Thank you so much.

extension_dir = "ext"

Well there you go, that's the problem. Did you copy this ini file from a windows machine?

No it was default. And its strange indeed to, file has many windows modules. If its not defaults, on linux, i might try to download or copy paste some, it was time ago im not quite remember.

When i try to debug, the debug console output changed. Yet PDO(in phpinfo) has no drivers. But (yes, i cleared the console) its still giving me the PHP related warnings about:

PHP Warning:  PHP Startup: Unable to load dynamic library 'pdo.so' (tried: /usr/lib/php/modules/pdo.so (/usr/lib/php/modules/pdo.so: cannot open shared object file: No such file or directory), /usr/lib/php/modules/pdo.so.so (/usr/lib/php/modules/pdo.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

Thank you for your help.

The first error is due to another clearly nonsensical line in your php.ini ("extension=pdo.so"). The others are due to you not having packages installed for extensions that you have enabled in your php.ini. Do you really want to use all of those extensions? Are are these also the result of just semi-randomly copy-pasting from other peoples' configs?

Given all these errors, and your apparent lack of knowledge of all the changes to your php.ini, I'd strongly advise you just reset it to the defaults for the package, and only make revisions you know you need.

Resetting it would make a lot of sense, yes. Is there a method other than reinstalling php? I don't need to use all this, no. As I said, I had them all enabled in case there was some kind of deficiency/requirement and if there was a bug due to that. Thinking about it again, though, as far as I remember, no, it's not copy and paste from windows.

I have them in the comment line now, but I still get errors:

PHP Warning:  Module "mysqli" is already loaded in Unknown on line 0
PHP Warning:  PHP Startup: Unable to load dynamic library 'pdo_dblib' (tried: /usr/lib/php/modules/pdo_dblib (/usr/lib/php/modules/pdo_dblib: cannot open shared object file: No such file or directory), /usr/lib/php/modules/pdo_dblib.so (/usr/lib/php/modules/pdo_dblib.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

Thank you very much for your help.

curl -sL $(pacman -Sp php) | bsdtar xOf - etc/php/php.ini

That will send the default content to stdout. You could add something like "| sudo tee /etc/php.ini" to the end to overwrite the current file.

Then follow the wiki to configure php as there are a couple things you are expected to change from the default.
