Not to be rude, but if one wants to improve one's Japanese further than just knowing a few sentence, this information isn't good at all. Simply because it isn't correct.
In Japanese, it is very important to make a difference between Subject and Topic.
Topic in Japanese use Wa. Subjects use Ga.
Even though there are sentences where ga/wa are interchangable, doesn't mean they mean the same.
Also wo is not a function marker, it is an object marker. It marks the direct object in a sentence. Transitive sentence(sentences with an object)such as "I stopped the car" takes wo (kuruma wo tometa). Intransitive sentences(without an object) takes ga . Example: (The car stopped) / Kuruma ga tomatta.
Further ni and he are not the same. They can be interchangable in almost all cases where ni marks direction, but the meaning slightly differs.
Osaka ni ikimashita = I went to Osaka
Osaka he ikimashita = I went in the direction of Osaka (which is pretty much same as I went to Osaka)
These sentences he/ni can be interchangable without much nuances, however this is only when ni marks direction.
My best tip for people interested in learning Japanese, is not to swallow all information you get on forums like this, but get a textbook so you can at least grasp the basic grammar of Japanese, then it will be much easier to pick up information elsewhere, and judge whether it is correct or wrong.
