I have a custom drupal 7 form as below

   $form['general_details'] = array(
         '#type' => 'fieldset',
         '#title' => t('General'),
         '#description' => t('General Information.'),
         '#required' => TRUE,
         );

   $form['general_details']['salutation'] = array(
         '#type' => 'select',....

I am getting an error in the line "$form['general_details']['salutation']" Error: Cannot use string offset as an array with PHP7.2

Can someone help ? Thanks in advance.

You must declare empty array before assign it

 $form = array();

$form['general_details'] = array(
         '#type' => 'fieldset',
         '#title' => t('General'),
         '#description' => t('General Information.'),
         '#required' => TRUE,
);

$form['general_details']['salutation'] = array(
         '#type' => 'select',....
