In PHPUnit, how do I indicate different with() on successive calls to a mocked method?

I want to call my mocked method twice with different expected arguments. This doesn't work because expects($this->once()) will fail on the second call.

$mock->expects($this->once())
     ->method('foo')
     ->with('someValue');

$mock->expects($this->once())
     ->method('foo')
     ->with('anotherValue');

$mock->foo('someValue');
$mock->foo('anotherValue');

I have also tried:

$mock->expects($this->exactly(2))
     ->method('foo')
     ->with('someValue');

But how do I add a with() to match the second call?

You need to use at():

$mock->expects($this->at(0))
     ->method('foo')
     ->with('someValue');

$mock->expects($this->at(1))
     ->method('foo')
     ->with('anotherValue');

$mock->foo('someValue');
$mock->foo('anotherValue');

Note that the indexes passed to at() apply across all method calls to the same mock object. If the second method call was to bar() you would not change the argument to at().
