From manual page: https://php.net/language.oop5.abstract

I suggest replace "may not" with "cannot" to make definition more accurate in sentence "Classes defined as abstract may not be instantiated, and any class that contains at least one abstract method must also be abstract.".

PHP error message is also unambiguous:
Error: Cannot instantiate abstract class MyAbstractClass in C:\path\to\file\index.php on line XYZ




Test script:
---------------
<?php

abstract class MyAbstractClass {

    public function test()
    {
        echo 'test';
    }

}

$a = new MyAbstractClass();
