php-ews: Class 'SoapClient' not found when using full path to the Classes

Question

Implementing php-ews on the existing non-OOP website.

Running standalone PHP script in shell works fine.

Standalone PHP script uses use:

use \jamesiarmes\PhpEws\Client;
use \jamesiarmes\PhpEws\Request\CreateItemType;

But I can't use use inside if-statements on the website, so I prepended all Classes using full path (i.e. new \jamesiarmes\PhpEws\Client).

Now I'm getting this error.

Fatal error: Class 'SoapClient' not found in /home/project/master/vendor/jamesiarmes/php-ntlm/src/SoapClient.php on line 13

I verified that Soap extension is installed. Please help. Thanks.

Answer 1

Running standalone PHP script in shell works fine.

but

I verified that Soap extension is installed.

How have you verified? You know you may be loading different php.ini files for CLI and Webserver environments.

(For example, in my Ubuntu server, with Apache webserver, I have both

/etc/php5/cli/php.ini

and

/etc/php5/apache2/php.ini )

Not answering your original question, but this one:

But I can't use use inside if-statements on the website, so I prepended all Classes using full path (i.e. new \jamesiarmes\PhpEws\Client).

use statements to import namespaced classes belong to the top of the file, outside any parentheses. They will always be "executed", i.e. create alias links inside the current namespace for the foreign class name (and if no namespace is being used, the root namespace is being used) - just for the current file they are in. So it is nothing permanent or reaching outside of the current file - new files may have different use imports, but they also have to repeat any imports if a class is being used in both files.

See http://php.net/manual/en/language.namespaces.php for the chapter on namespaces at large and http://php.net/manual/en/language.namespaces.importing.php for using use in particular. Note example 5 with an illegal code:

<?php
namespace Languages;

function toGreenlandic()
{
    use Languages\Danish;

    // ...
}
?>

Importing classes with use is independent from the execution of code. It already happens when parsing the file to allow PHP to know the fully qualified name of all classes that are being used in the code. They will only be autoloaded when the code gets executed, but use should be kept at the top of the file.
