Using a PHP use keyword conditionally-CodePudding

Looked around and can't really find an answer.

I have a web app that is sending SMS messages using the Twilio SDK

Some installs have Twilio installed and some do not.

I want this code to run only if the Twilio files exist.

The regular code is:

require_once ABSPATH.'php/vendor/twilio-php-master/Twilio/autoload.php';
use Twilio\Rest\Client;

I have tried

if(file_exists(ABSPATH.'php/vendor/twilio-php-master/Twilio/autoload.php')) {
    require_once ABSPATH.'php/vendor/twilio-php-master/Twilio/autoload.php';

    use Twilio\Rest\Client;
}

and also

if(file_exists(ABSPATH.'php/vendor/twilio-php-master/Twilio/autoload.php')) {
    require_once ABSPATH.'php/vendor/twilio-php-master/Twilio/autoload.php';
}
if(class_exists(Twilio\Rest\Client)) {
    use Twilio\Rest\Client;
}



if(file_exists(ABSPATH.'php/vendor/twilio-php-master/Twilio/autoload.php')) {
    require_once ABSPATH.'php/vendor/twilio-php-master/Twilio/autoload.php';

}

use Twilio\Rest\Client;

and always get

syntax error, unexpected 'use'

Is there a way to make this conditional?

CodePudding user response：

Why not use use unconditionally?

 <?php
 use Twilio\Rest\Client;

 if (is_file(ABSPATH.'php/vendor/twilio-php-master/Twilio/autoload.php')) {
      require_once ABSPATH.'php/vendor/twilio-php-master/Twilio/autoload.php';
 }

I can run this code without any issue.

Probably risking name conflicts with Twilio\Rest\Client but I think you'd have this either way.

Thank you marco-a

Ended up using

use Twilio\Rest\Client;

 if (file_exists(ABSPATH.'php/vendor/twilio-php-master/Twilio/autoload.php')) {
      require_once ABSPATH.'php/vendor/twilio-php-master/Twilio/autoload.php';
 }

Still not sure why putting the use statement before works, but it does lol
