Define and throw a dedicated exception instead of using a generic one. Open

If you throw a general exception type, such as ErrorException, RuntimeException, or Exception in a library or framework, it forces consumers to catch all exceptions, including unknown exceptions that they do not know how to handle.
Instead, either throw a subtype that already exists in the Standard PHP Library, or create your own type that derives from Exception.
Noncompliant Code Example
throw new Exception(); // Noncompliant
Compliant Solution
throw new InvalidArgumentException(); // or throw new UnexpectedValueException();
See
- MITRE, CWE-397 - Declaration of Throws for Generic Exception
- CERT, ERR07-J. - Do not throw RuntimeException, Exception, or Throwable
Define a constant instead of duplicating this literal "isVisible" 4 times. Open
'isVisible' => null,
- Read upRead up
- Exclude checks
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.
Reduce the number of returns of this function 5, down to the maximum allowed 3. Open
private function asItem($item, $index = null)
- Read upRead up
- Exclude checks
Having too many return statements in a function increases the function's essential complexity because the flow of execution is broken each time a return statement is encountered. This makes it harder to read and understand the logic of the function.
Noncompliant Code Example
With the default threshold of 3:
function myFunction(){ // Noncompliant as there are 4 return statements if (condition1) { return true; } else { if (condition2) { return false; } else { return true; } } return false; }

Having two cases
in a switch
statement or two branches in an if
chain with the same implementation is at
best duplicate code, and at worst a coding error. If the same logic is truly needed for both instances, then in an if
chain they should
be combined, or for a switch
, one should fall through to the other.
Noncompliant Code Example
switch ($i) { case 1: doSomething(); break; case 2: doSomethingDifferent(); break; case 3: // Noncompliant; duplicates case 1's implementation doSomething(); break; default: doTheRest(); } if ($a >= 0 && $a < 10) { doTheThing(); else if ($a >= 10 && $a < 20) { doTheOtherThing(); } else if ($a >= 20 && $a < 50) { doTheThing(); // Noncompliant; duplicates first condition } else { doTheRest(); } if ($b == 0) { doOneMoreThing(); } else { doOneMoreThing(); // Noncompliant; duplicates then-branch } var b = a ? 12 > 4 : 4; // Noncompliant; always results in the same value
Compliant Solution
switch ($i) { case 1: case 3: doSomething(); break; case 2: doSomethingDifferent(); break; default: doTheRest(); } if (($a >= 0 && $a < 10) || ($a >= 20 && $a < 50)) { doTheThing(); else if ($a >= 10 && $a < 20) { doTheOtherThing(); } else { doTheRest(); } doOneMoreThing(); b = 4;

Exceptions
Blocks in an if
chain that contain a single line of code are ignored, as are blocks in a switch
statement that contain a
single line of code with or without a following break
