Sharing some naming conventions is a key point to make it possible for a team to efficiently collaborate. This rule allows to check that all local variable and function parameter names match a provided regular expression.

Noncompliant Code Example

With the default regular expression ^[a-z][a-zA-Z0-9]*$:

public function doSomething($my_param){
  $LOCAL;
  ...
}

Compliant Solution

public function doSomething($myParam){
  $local;
  ...
}

Exceptions

Loop counters are ignored by this rule.

for (int i = 0; i < limit; i++) {  // Compliant
  // ...
}
