PHP 警告：PHP 启动：无法加载动态库 '\\xampp\\php\\e xt\\php_pgsql.dll

Question

我尝试使用 zend 框架，但是当我通过命令提示符创建项目时，警告即将到来，警告是PHP 警告：PHP 启动：无法加载动态库 '\\xampp\\php\\e xt\\php_pgsql.dll

Answer 1

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! :)

Tested these steps on Windows 8, I assume this works on other old versions too :)

Answer 2

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!

Answer 3

您可以修改 php.ini 文件以启用 php_pgsqlsql.dll
