Building Database Applications in PHP

102 notes

Cours 3 sur 4 dans Specialization Web Applications for Everybody

In this course, we'll look at the object oriented patterns available in PHP. You'll learn how to connect to a MySQL using the Portable Data Objects (PDO) library and issue SQL commands in the the PHP language. We'll also look at how PHP uses cookies and manages session data. You'll learn how PHP avoids double posting data, how flash messages are implemented, and how to use a session to log in users in web applications. We'll then build the first 'complete' application that has multiple screens to Create, Read, Update and Delete (CRUD) our data. This brings all the previous concepts together and will form the basis for all later web applications.

À partir de la leçon

PHP Redirect, Routing, and Authentication

We look at how PHP avoids double posting data, how flash messages are implemented, and how we use a session to log in users in web applications.

Charles Severance
Associate Professor
School of Information

Well, hello! We are at Bletchley Park where computer science,

internet, history, technology and all of computation started here at Bletchley Park.

And we've had a very special record

setting office hours and I want you to meet your fellow students.

Okay, so here we go. So Howdy!

State your name and.

Hi! I'm Steve.

Well, also but you should say that you're somebody special,

you're not just Steve.

Well, I'm one of the mentors for the Python course. All of them.

So welcome, Steve!

It's a honor to have worked with you all these years, right.

Steve is the one that does all of the hard work.

I get all the credit and people like Steve and other mentors,

they actually do the hard work.

So, thank you, Steve. Thank you so much.

Well, thanks for inviting me down with your help, it was brilliant.

Yeah. So say hi the rest class.

Hi! I'm Benoit.

Okay.

Originally from France. I live here in London,

very happy to be here and meet you, Dr. Chuck.

I'm happy to meet you.

I've done the Internet history class.

I really loved it, I'm really keen to do the next one and the Python.

Cool. And don't worry,

it's a very wide angle,

so I'm not really taking a picture of your nose.

Hi! I'm Craig.

I am doing the Python web data and see you online.

Okay. Did you get in trouble when that guy come talk to you?

Yeah.

Really.

Yeah.

You okay though.

Yeah, I'm fine.

They going to let you come back.

Yeah, I'm fine.

Good. Okay. Say hi.

I'm Steve.

I've done the first Python course and I'm

going to be doing some of the other soon and I found it really,

really useful in getting my way into the language, it's really helpful.

Thanks.

Hi, I'm Jenny and I'm a software developer and I use the Python for

Everybody course to teach

a programming class at an international school in Chiang Mai, Thailand.

And it's good to be here at the Bletchley Park, England.

You know that the books translated into Chinese, right.

Does that work in Thailand?

Not so well.

Okay, I guess I'm not that cool.

Different script.

Okay. Okay.

Hello! I'm Arnaud from France.

I work in my university as an Arduino instructor and

because of the Python class I forgot the syntax of Arduino,

that was embarrassing in my job.

You mean processing. You mean,

you don't use processing anymore.

You use Python instead of processing.

No, I use Arduino.

I'm supposed to do debugging at the university,

but they add a semicolon everywhere

and then I forgot the Python so it made it embarrassing.

Welcome! Did you travel from Paris?

Yeah.

You came from like Paris to here.

Yes, I do.

I guess it is from Eurostar.

It's not like coming from Australia, right. I guess it's not.

Someone beat me, huh.

No, no, no, I am not saying.

You're right, Eurostar, Paris is closer than we think.

I'm Kevin. I've only come from London but it's been really good to hear

Coursera is put together and how you make the course and thank you.

Well, thanks for coming.

Hi, I am Xiangyang.

I am Sapu. We are from China.

We're living here.

You're students?

Yeah, we are working in the UK at the moment.

Okay.

So it's nice to meet you here at Bletchley Park and Python course is great.

Yeah.

Cool.

Hello! I'm Yannis.

I used to work with Python for a long time but it's the first time that

I'm taking a course just to see the language properly. Thank you.

Hello! I'm Isabelle.

I use your courses to refresh my computer science knowledge.

Yes.

I'm learning Python with you.

I've come to Bletchley Park at least five times.

Like you, you're a fan like me.

I would love to have worked here during the war.

Must have been so exciting.

Yeah. You know three-quarters of the people here were women.

Yeah.

Yeah. Very impressive.

We don't have the most interesting jobs all of them, but we'd have changed that.

Exactly. Exactly.

Hi! I'm Patrick. I did the Internet history course

and it's a very exciting day for me today

because when I did that course I said I

wanted to go to Bletchley Park and I'm here today.

And I also said I wanted to come to one of Dr. Chuck's office hours,

so I got to do two at once today which is quite brilliant.

Yeah, one of my ideas is that this is our class reunion.

Yeah.

That was kind of the I was thinking that we could have a class reunion.

Hi! I'm David. I've taken your Python course

and your Internet History course, loving them.

Welcome. Glad you're here.

Hi! I'm Paul, and I've done the Python courses and they're great.

Thank you.

Hi! I'm Hugh from Cambridge and I've

done your Python courses and I'm currently doing the web one.

I'm very excited to be here with you.

And it's great to try and teach kids,

so I'm actually learning it because my son is doing Python for his exams,

so hopefully I can help him.

Great. You're only like a couple of blocks away from Raspberry Pi headquarters, right?

Here in Cambridge. And they're doing Python stuff there too as well.

Big time.

Yeah, I'd like to get that all connected somehow.

Think of a cunning plan.

Yeah.

Hi! I'm Roger. I have done the Python for Everybody course and I've

just started the web one and I am really looking forward to getting right through it.

Cool.

Hi! I'm Thaddeus.

I come originally from Poland,

I live here in UK.

I just started my journey with Python.

I should say thank you very much for everything you're doing.

It's really, really good stuff. And- yes?

So here's the question. Do you know the history

of Bletchley Park and the three Polish cryptographers.

Oh, it was very,

very underrated what they did for us.

Well, I bet everybody who's historians here have done

a really good job of making that clear.

Which brings me to the next question,

when you're going to come to the office hours to

Poznan in Poland.

You have a lot of friends there.

Well, I go many places,

so maybe we'll figure that out.

Okay.

One more thing. Hello to my wife and two daughters.

There you go.

Hi!

I'm Maddie. I live just live north of London.

I took the first Python course so I could keep up with

my boy who's learning it in

school basically. It's lovely to meet you. Thank you very much.

Great. Well, lovely to meet you.

Hello there!

My name is Andrew.

I'm a pensioner, just doing the Python course for interest and I'm hoping

to combine that with the little projects I've got with the Raspberry Pi.

Very good.

But I think the Python course is a gripping course. Well done!

You're very young for a pensioner.

Indeed. Far too far into my 70s.

Hello! I'm Adam.

I came with my family and I just started to learn the Python.

I'd like to use in my work,

job and later I would

like to teach my daughter programming.

Yeah. At some point that'll become normal.

Just our next generation of codebreakers.

Exactly.

Important to bring them to the ground zero.

Ground zero. Ground zero of it all.

And in the future it will be so much better.

We break this ground and it'll stay broken.

Definitely.

Hi! I'm Alice. I live in Bristol

Bristol? That's far away. That's that way.

It's a couple of hours, yeah,

southwest. So I did

the Python course a few months ago and I'm

going to do a new one, that you've come- the three, course three.

Yeah, course three. Looking forward to see you in course three.

Yeah, they're really good.

I tried some other ones from Coursera and they weren't anywhere near as good.

I'll have to cut that out. Maybe I won't cut that part out.

Hi! I'm Yang. It's nice to see you in real life finally.

I'm an analyst, so I hope to be able to use your work,

learning Python and apply it to my work,

so I'll follow you to Capstone, I'm pretty sure.

Well, great.

Keep up the good work.

Well, hopefully I'll figure out the Capstone by the time we get to Capstone.

Hi!

Hi! I'm David.

I'm from Ormskirk, north of Liverpool.

I work as a learning technologist and I'm interested in doing the Python course

to bring my programming skills up-to-date.

I am learning technologist myself.

Yeah.

Yeah. Hello!

Hi! I'm Cynthia.

And I'm taking your Python course which is excellent.

I highly recommend it for anyone who wants to learn programming and I'm on

a career break right now raising Aiden and Tyco.

Hello!

Hello!

And it's been great for maintaining intellectual sanity.

That is a use case that's very important actually.

But your career has something to do with nuclear reactors or stealth aircraft.

No, no, no. Mass spectrometry.

Oh, mass spectrometer. Whatever, I knew it was complex.

So without the computational part,

mass spectrometry is so useless.

Well, mass spectrometry is a needle in a haystack problem.

Yeah. But if it weren't for the programming we couldn't make any sense of that data.

Right.

I never knew how to do that before and I hope when

I go back I'll actually know what I'm doing.

Well, great. Great. That's a great way to do a career career break.

Hi! My name is Arthur and I'm from London and I've done

Internet and history technology course

and I'm looking forward to doing the Python course.

Great. Great. Do you want be on? Are you hiding?

No, no it's just my wife.

Okay, okay you're the photographer.

Okay, so we'll get a wide shot of you all.

Give yourself a large round of applause for like your awesomeness and initiative.

So, there we have it,

the first first perhaps of many class reunions here at Bletchley Park.

So, see you on the net.
