Drupal 7 theme Template.php Unexpected T_OBJECT_OPERATOR error

Question

I'm new to Drupal development and trying to run a preprocess function for a content type inside my custom theme's template.php.

Here's my code:

function MYTHEME_preprocess_article(&$variables) {
  if (!field_image_alt_text->getValue().strlen() = 0 || null ) { set value to something }else {return;}
};

but it returns a syntax error as:

Syntax Error: Unexpected T_OBJECT_OPERATOR

How can I . resolve this error?

Thanks in advance!
