You can use IMCE to select a file.

Method 1 : Form hook_page_attachments

This method allow to store data on drupal session using drupal session table (not php $_SESSION).
Storage is different for each users ans each visitors if anonymous

Syntax:

\Drupal::service('page_cache_kill_switch')->trigger();

Example on a controller:

Create a Drupal 9 project with composer

Error N°1 : PHPunit not found

If uou have a message like : Add Phpunit via composer

CAUTION : PHPunit Version >= 8 is not compatable with drupal, so use the 7

composer require --dev phpunit/phpunit:7

This is usefull if you want to do some actions just one time.

The drush comman is php-script alias src

On drupal 8 with drush

Example :
drush --uri=drupal.loc scr /modules/custom/mymodule/scripts/test-script.php

Example :

$stopwords = ['toto', 'Pied', 'the'];
$str = 'bla bla toto bla bla Toto bla bla Tôtô bla bla totô bla bla bla bla the thé pied pïed pîéd';

function MYMODULE_views_pre_render(ViewExecutable $view) {
 if ($view->id() == 'ABC') {
  $view->setTitle('MY CUSTOM TITLE');
 }
}

Drush 9 is finally here with some much-awaited changes. Drush 9 commands are now classes and .inc files are obsolete. Drush commands will now be based on the Annotated Command format. This will change the fundamental structure of custom Drush commands.
