Define a constant instead of duplicating this literal "weathermap_final_memory" 4 times.

if (isset($values['weathermap_final_memory']) && isset($values['weathermap_initial_memory']) && $values['weathermap_loaded_memory'] && isset($values['weathermap_highwater_memory'])) {

Duplicated string literals make the process of refactoring error-prone, since you must be sure to update all occurrences.

On the other hand, constants can be referenced from many places, but only need to be updated in a single place.

Noncompliant Code Example

With the default threshold of 3:

function run() {
  prepare('action1');                              // Non-Compliant - 'action1' is duplicated 3 times
  execute('action1');
  release('action1');
}

Compliant Solution

ACTION_1 = 'action1';

function run() {
  prepare(ACTION_1);
  execute(ACTION_1);
  release(ACTION_1);
}

Exceptions

To prevent generating some false-positives, literals having less than 5 characters are excluded.

There are no issues that match your filters.
