In My Case, my XAMPP was installed in the following path:

C:\xampp

And also when I try to run the following command on CMD,

any_drive_and_path_here>php phpFile.php

It gave me warning error messages like above, more than 15+!!!(And I had to do the following steps to resolve for each of the warning messages.)Then I searched the Google. And I got the idea into mind, whatever it is these modules are gonna be loaded, just because that the relevant line for each module in php.ini file has been un-commented (removing the semicolon ";" at the beginning of each line for each relevant module in php.ini file).And also as the error msg has given I checked if the extention dll file exists in the

xampp\php\ext directory.

(those extentions were there.)

Then I read the php.ini file instructions which is at the top of that file! :) It has given the instructions, to modify the path in each extension enabling lines.

Summary And To-Do :

In this case, relevant to this warning: Tip:if your XAMPP is installed in the following path "C:\xampp\" find and modify the following line(lines if you have more warnings than this)

From: extension=php_pgsql.dll
To:   extension=C:\xampp\php\ext\php_pgsql.dll

And then whenever you start the CMD and try executing the php command, php.ini knows where the exact place your extension.dll file resides in! :)

Hint: Don't Forget To Read the php.ini file instructions which is at the top! :) Hope This Answer Helped You All Who Uses Windows!(These steps worked on Win 8, I assume this works on other old versions too) :)

Thanks for taking time to read the answer!!! Best Regards

Could somebody help me ? Thanks. Running in PHPstorm, Win 10

Somewhere in your php.ini the extension php_pgsql.dll is being tried to load. But could not be loaded.

Look for lines like extension=php_pgsql.dll in your php.ini then remove it.

But if you are working pgsql then you need fix the dll or find an alternate extension that works!

• I don't know Xampp very well, I usually use a LAMP stack. Anyway, this error is pretty straightforward: you need to avoid the load of this extension in your php.ini, or install the required dll if you need PostreSQL
• I guess you better check my answer at the very end! :) Sorry if that doesn't help you! :/
