Can anyone better explain what the keyword new does?

The video explains that you need to use the keyword new when creating an object but does not explain why. In later videos you use the keyword new but it's not clear why it's needed or what happens if you leave it out.

If you don't use new your code will probably break. PHP will think you are assigning a new variable and look for the typical variable types. Once you assign it to a class with new, then you can invoke the class methods and properties.

a class is a chunk of code you want to use over and over. Each time you want to use it you have a new use, which allows new info to be passed. Each instance of your object can store its own parameters with the same name at the same time because each instance is a new version of using the code.

So if I dont use the "new" keyword then will the new object use only default data(assume I assign default data)? Or will the code just break entirely?
