php blowfish hashing with crypt(): the CLI result differs from webserver's one

When I use php function crypt() using Blowfish algorithm with web-server:

<?php

    echo crypt('SAD123', sprintf('$2a$10$%s', '7711cbpe58dfpogiu049857f011werb0'));

I get this result: 

$2a$10$7711cbpe58dfpogiu0498u5Vh773A3qx.3LE3ro3NX7F9c9N7.pOm

But if I'm using PHP interpretor with command line:

php -r "echo crypt('SAD123', sprintf('$2a$10$%s', '7711cbpe58dfpogiu049857f011werb0'));"

I'm getting another result:

a0SqNHxQ8/2mA

Do you have any ideas?

The system is: Apache/2.2.3 (CentOS), PHP Version 5.4.26

This is because the dollar-signs with the following digits in your command-string are also interpreted as positional parameters in bash.

When you escape them, it will work as expected:

$ php -r "echo crypt('SAD123', sprintf('\$2a\$10$%s', '7711cbpe58dfpogiu049857f011werb0'));"

So when you want to tinker with some PHP in your comman line, you should just run it interactively:

$ php -a
php > echo crypt('SAD123', sprintf('$2a$10$%s', '7711cbpe58dfpogiu049857f011werb0'));
