=== Noncompliant code example

[source,php]
----
"/a++abc/"              // Noncompliant, the second 'a' never matches
"/\d*+[02468]/"         // Noncompliant, the sub-pattern "[02468]" never matches
----


=== Compliant solution

[source,php]
----
"/aa++bc/"              // Compliant, for example it can match "aaaabc"
"/\d*+(?<=[02468])/"    // Compliant, for example it can match an even number like "1234"
