Php Standalone Skript doesnt Query Database, APIv4 Simple Example

Question

I tried to write a Standalone PHP-Skript for CiviCRM and looked after the Simple Example, but unfortunately it doesnt return something.

<?php
require_once '/var/www/html/wp-content/plugins/civicrm/civicrm/civicrm.config.php';
require_once $civicrm_root . '/CRM/Core/Config.php';


$config = CRM_Core_Config::singleton();

$contacts = \Civi\Api4\Contact::get()
  ->addSelect('first_name')
  ->addWhere('contact_type', '=', 'Individual')
  ->setLimit(25)
  ->execute();

foreach ($contacts as $contact) {
    echo $contact;
}

The variable $civicrm_root is loaded by the civicrm.config.php and is the absolute path to my civiCRM root: /var/www/html/wp-content/plugins/civicrm/civicrm/. I looked up both config files, they exist and I crosschecked the querycode against the APIv4 Explorer, and it works, I dont know what the problem is.

System:

• Debian 11 VM
• Apache 2.4.54
• PHP 7.4.30
• MariaDB: 10.5.15
• Wordpress: 6.0.1
• CiviCRM: 5.52.0 I hope there is a Idea for a solution. Thanks in advance!

Edit I

I applied the suggestions and invoke it with ~/buildkit/bin/cv scr myscript.php but no return value either.

<?php
$config = CRM_Core_Config::singleton();

$contacts = \Civi\Api4\Contact::get()
  ->addWhere('contact_type', '=', 'Individual')
  ->setLimit(25)
  ->execute();

foreach ($contacts as $contact) {
    echo $contact['first_name'];
}

EDIT II

I tried cv api4 Contact.get +w 'contact_type = "Individual"' +l 25 and it works, still: whats wrong with the script?

EDIT III

I insert the line echo count($contacts);, and this return 0.

Answer 1

I wouldn't do it that way. I'd remove those first two lines and install cv - if you are using buildkit you already have it - and then run it with cv scr myscript.php.

That way it runs on all cmses, and you can do other neat stuff like cv scr --user=demo myscript.php to run it as the user named demo to test different permissions, run it with -vvv to get some debugging, etc...

Separate note: $contact is not a string so you can't echo it. You can do something like var_export($contact).

Answer 2

In Combination out of Demerits posts i can solve the problem via

cv scr --user=some_wordpress_username skriptname.php

Thanks for the support.
