You could show what you've done so far.

Let's say you have square 1 - it will be player - and square two - which will be wall.

You have to do four ifs to check if collision happened:

if(player is on the left side of wall)
{
collision = false;
}
else if(player is on the right side of wall)
{
collision = false;
}
else if(player is under the wall)
{
collision = false;
}
else if(player is above the wall)
{
collision = false;
}
else
{
 collision = true // Player isn't outside the box, so he must be inside, or collide with it :)
}

Try to make it yourself.

Cheers!
