Coding Style Compatibility introduced by
For compatibility and reusability of your code, PSR1 recommends that a file should introduce either new symbols (like classes, functions, etc.) or have side-effects (like outputting something, or including other files), but not both at the same time. The first symbol is defined on line 17 and the first side effect is on line 12.

The PSR-1: Basic Coding Standard recommends that a file should either introduce new symbols, that is classes, functions, constants or similar, or have side effects. Side effects are anything that executes logic, like for example printing output, changing ini settings or writing to a file.

The idea behind this recommendation is that merely auto-loading a class should not change the state of an application. It also promotes a cleaner style of programming and makes your code less prone to errors, because the logic is not spread out all over the place.

To learn more about the PSR-1, please see the PHP-FIG site on the PSR-1.

Coding Style Compatibility introduced by
PSR1 recommends that each class must be in a namespace of at least one level to avoid collisions.

You can fix this by adding a namespace to your class:

namespace YourVendor;

class YourClass { }

When choosing a vendor namespace, try to pick something that is not too generic to avoid conflicts with other libraries.

Coding Style introduced by
initExtension uses the super-global variable $GLOBALS which is generally not recommended.

Instead of super-globals, we recommend to explicitly inject the dependencies of your class. This makes your code less dependent on global state and it becomes generally more testable:

// Bad
class Router
{
    public function generate($path)
    {
        return $_SERVER['HOST'].$path;
    }
}

// Better
class Router

    public function __construct($host)
    {
        $this->host = $host;
    }

    public function generate($path)
    {
        return $this->host.$path;
    }

Unused Code introduced by
This if statement is empty and can be removed.

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.

Unused Code Comprehensibility introduced by
55% of this comment could be valid code. Did you maybe forget this after debugging?

Sometimes obsolete code just ends up commented out instead of removed. In this case it is better to remove the code once you have checked you do not need it.

The code might also have been commented out for debugging purposes. In this case it is vital that someone uncomments it again or your project may behave in very unexpected ways in production.

This check looks for comments that seem to be mostly valid code and reports them.

The method onExtensionFunction() contains an exit expression.

An exit expression should only be used in rare cases. For example, if you write a short command line script.

In most cases however, using an exit expression makes the code untestable and often causes incompatibilities with other libraries. Thus, unless you are absolutely sure it is required here, we recommend to refactor your code to avoid its usage.
