=== Code examples

==== Noncompliant code example

With the default threshold of 3:

[source,php,diff-id=1,diff-type=noncompliant]
----
function run() {
  prepare('this is a duplicate'); // Noncompliant - 'this is a duplicate' is duplicated 3 times
  execute('this is a duplicate');
  release('this is a duplicate');
}
----

==== Compliant solution

[source,php,diff-id=1,diff-type=compliant]
----
MESSAGE = 'this is a duplicate';

function run() {
  prepare(MESSAGE); // Compliant - the duplicated string literal is replaced by a constant and can be safely re-used
  execute(MESSAGE);
  release(MESSAGE);
}
----

[source,php]
----
$severity = $request->getParam('severity-score');
