[Editor's note: that behavior is caused by a bug in PHP 7.0, which has been fixed as of PHP 7.0.7.]



Regarding the entry "Import names cannot conflict with classes defined in the same file".

- I found that since PHP 7.0 this is no longer the case.

In PHP 7.0 you can have a class with a name that matches an imported class (or namespace or both at the same time).



<?php

namespace ns1 {

  class ns1 {

    public static function write() {

      echo "ns1\\ns1::write()\n";

    }

  }

}



namespace ns1\ns1 {

  class ns1c {

    public static function write() {

      echo "ns1\\ns1\\ns1c::write()\n";

    }

  }

}



namespace ns2 {

  use ns1\ns1 as ns1; // both a class in ns1, and a namespace ns1\ns1

    

  // the next class causes fatal error in php 5.6, not in 7.0

  class ns1 {

    public static function write() {

      echo "ns2\\ns1::write()\n";

    }

  }

    

  ns1::write(); // calls imported ns1\ns1::write()

  ns1\ns1c::write(); // calls imported ns1\ns1\ns1c::write()

  namespace\ns1::write(); // calls ns2\ns1::write()

}
