			0 ignored issues – show Bug introduced 2017-06-06 12:47 UTC by Report Bug Copy Issue Report The property `head` does not exist. Did you maybe forget to declare it? In PHP it is possible to write to properties without declaring them. For example, the following is perfectly valid PHP code: class MyClass { } $x = new MyClass(); $x->foo = true; Generally, it is a good practice to explictly declare properties to avoid accidental typos and provide IDE auto-completion: class MyClass { public $foo; } $x = new MyClass(); $x->foo = true; Loading history...

This check looks for the bodies of `if` statements that have no statements or where all statements have been commented out. This may be the result of changes for debugging or the code may simply be obsolete. These `if` bodies can be removed. If you have an empty if but statements in the `else` branch, consider inverting the condition. if (rand(1, 6) > 3) { //print "Check failed"; } else { print "Check succeeded"; } could be turned into if (rand(1, 6) <= 3) { print "Check succeeded"; } This is much more concise to read.

In this case it is vital that someone uncomments it again or your project may behave in very unexpected ways in production.
