Zend不会加载pdo_dblib

Question

I'm trying to connect a Zend application (version 1.11.11) to an mssql server via pdo_dblib (using PHP version 7.0.22). I know that my PHP installation has pdo_dblib since running print(extension_loaded('pdo_dblib')); in the terminal returns 1 . In the .ini file I have:

resources.db.adapter = "pdo_mssql"
resources.db.params.pdoType = "pdo_dblib"

When I run the application with a debugger, the value of the statement $a = extension_loaded('pdo_dblib'); is false .

As a result of this PDO::getAvailableDrivers() doesn't contain pdo_dblib (of course), which causes the application to throw an exception.

Does anyone know why this problem occurs, and how to fix it?

Answer 1

The key is not Zend, but in a subtle detail of your tests:

• running print(extension_loaded('pdo_dblib')); in the terminal returns 1
• when I run the application with a debugger, the value of the statement $a = extension_loaded('pdo_dblib'); is false

PHP on the terminal is not guaranteed to have the same configuration, or even be the same version, as PHP on the web server of the same machine.

You will need to look into your hosting setup to find out how to enable the extension in the php.ini (or equivalent) in the web server's copy of PHP. The output of phpinfo() run in your application, not the terminal , may help.
