InfinityLoop

error on by default

Group: Probable bugs · PhpStorm name: InfinityLoopInspection

A method whose only statement calls the very same method on $this, self or static recurses unconditionally until the stack overflows — typically a getter/proxy that was meant to call a property, a parent method or a differently named method.

Example

<?php
class Settings
{
    private $theme;

    public function theme()
    {
        return $this->theme();
    }

    public static function boot($env)
    {
        static::boot($env);
    }

    protected function flush()
    {
        // delegate
        self::flush();
    }

    public function locale()
    {
        return $this->theme;
    }

    public function reload()
    {
        return parent::reload();
    }

    public function save()
    {
        return $this->Save();
    }

    public function sync()
    {
        return ($this->sync());
    }

    public function close($n)
    {
        if ($n > 0) {
            return $this->close($n - 1);
        }
    }
}
