Hello in this video I am going to show you how to use a for each loop. So a for each loop is essentially a more specific for loop that is designed for basically go going over an array for example and if I create an array here so if you don't understand anything that I do with arrays, feel free to check out the arrays video. Okay so I create an array on a call it guru calls and row just makes in here the Faraday Future with the Hagia future we're not sure about that to you to do to do this, she and I will put one more I put messy, I always get confused in the sight of who will asaurus It's with a guess. Okay. Okay, the best part of the day. That's that's probably why they're confused maybe?
No. Okay, so if we wants to print out one of these values, let's ignore the loop. For now, I want to comment out what's inside, so we won't get any disturbance from that, you'll just do the name of the variable. And to access it, you put zero for example, which accesses the first one. So we could echo this out and we get BM two, that's pretty easy. We wanted to access you know, a number one, like the second one, we could do that.
And let's put them on separate lines. So let's enclose this in quotation marks. And I'm going to put a brake line probably just be the if I copy all of this, and this changes to old one. Okay, so that's fine. But I think if he can get quite tiresome to basically access them one by one, if essentially, you know what you're gonna be doing with each one, this has the same maybe you're printing it like this, maybe you gain all of them and print storing them in a database or maybe from a database, you've got an array of email addresses and you want to go over every single one and maybe see your mailing list on your fantastic website and you want to email the user of some new promotion for example. This can be very tiresome if you have 10 2030 hundred thousand, no a million item for example, in the erase instead of this.
What you can do is use a for loop and yes, this is the for each video. So I will begin on today in a second. So to do it in here, we could just put, you know count dollar cars and then we would just say echo dollar cause I breaking out. And this will print them all out, undefined in tech index. Go. Okay, it prints all of them out.
But if that's all we're doing in our inside of my boy for we're doing it basically acts in each element in our array. There's the for each loop, which is a lot easier to use. So you do for each. And in here, you don't put any variable like this, you don't have an index or any iterator or any condition, all you do is put the name of the array, so calls, say as an as value. And that's it. This little line basically says, loop over this array, and every single item that you find in there so in this case, BMW Faraday Future Toyota, Mitsubishi, and Mercedes store it into this variable, dollar value, which is has a local scope and now we can literally just Copy and paste this, Copy that, paste it there and run it.
Oops, don't want that $1 value. There we go. And if I was to comment this so when you accidentally get up source code, you can see the difference between the two. There you go. That is basically a much simpler version of that for loop. So if you need a for loop for simply looping over every single value in an array could be a multi dimensional array doesn't matter, then the for each loop is just a better and easier thing to use.
That's it. Any questions, feel free to pop me a message. And as usual, I look forward to seeing you in the next video.
