Shared coding conventions allow teams to collaborate efficiently. This rule checks that all constant names match a provided regular expression.

Noncompliant Code Example

With the default regular expression ^[A-Z][A-Z0-9]*(_[A-Z0-9]+)*$:

define("const1", true);

class Foo {
    const const2 = "bar";
}

Compliant Solution

define("CONST1", true);

class Foo {
    const CONST2 = "bar";
}
