I am using a shared hosting through CIPL.in. They use cpanel. I am trying to deploy a ZEND app on my website. However it keeps giving the error.
An error occurred
Application error
Exception information:
Message: The PDO extension is required for this adapter but the extension is not loaded

Also when I try to print out the phpinfo I get:

However when I get back to my hosting providers, they tell me that they have modified the php.ini to enable the PDO support and they will check again. What is it that I need to do or ask my hosts to do?
The configure command in your PHP output shows:
'--disable-pdo'
so I think it's safe to assume that they haven't enabled it.
if (!defined('PDO::ATTR_DRIVER_NAME')) {
echo 'PDO unavailable';
}
elseif (defined('PDO::ATTR_DRIVER_NAME')) {
echo 'PDO available';
}
I hope this works
Does this application want Pdo_Mysql? If so you may be able to use the Mysqli adapter instead - it depends on the software but it's possible.
In the area where you set your database connection details, there's probably an option called 'adapter'. Try setting its value to 'mysqli'
