True / False Evaluation Questions

[timothyarden]

Hi Freaks,

Just some quick questions:

 

1) Assuming the function test() returns a true or false value, would these two pieces of code process the same? (if not could you please explain why)

if(test()){
// action(s)
}

//and

if(test() === true){
//action(s)
}

 

2) Same question except for false:

if(!test()){
// action(s)
}

//and

if(test() === false){
//action(s)
}

 

3) if the function returned a string / integer / array / true on success or false on failure would the actions in the if loop execute? (assuming that the function test returned success and therefore was a string / integer / array / true):

if(test()){
// action(s)
}

 

 

Thanks for reading and for everyones help in advance. I know this kind of post would generally be responded to with go try it for yourself but my XAMPP has currently been not allowing me to turn on Apache because of an error.

Or, you could look at the manual.

Thanks for the link trq. That answers the first question and I assume it is the same for the second?

[trq]

It should answer all of your questions.

[timothyarden]

Sorry, yep your right. Thanks for your time and help

Plus, the most effective way to find out "does this do that?" Is to... Do it.

[timothyarden]

Thanks for the advice Jessica, but as I said in my first post XAMPP's Apache process won't start.

You can run PHP scripts from the command-line as well --- no Apache needed.

Hell, in 5.4 php has a web server built in. No need for Apache or Nginx anymore for development.

Hi David,

I am coding on a Windows 8 PC. Are you sure I can run it from the command line? (I assume you mean command prompt)

 

And I thought you couldn't install PHP on Windows PC trq?

 

Thanks for the help and advice guys

[trq]

And I thought you couldn't install PHP on Windows PC trq?

 

What makes you think that?

[timothyarden]

Thats what I was told by a friend who does PHP Development

[timothyarden]

I thought it was only able to be run on Linux and ASP on PCs?

[trq]

PHP is cross platform. Most hosting is Linux. It's not something I would recommend (I wouldn't recommend Windows for anything though) but a lot of people still develop locally on Windows.

[timothyarden]

Okay, thanks for that info trq. Really appreciated

[Jessica]

If you want to do PHP development and your development environment is not working, I would make that priority # 1

 

[DavidAM]

If you installed XAMP on Windows, then you have PHP installed on Windows. I have LAMP running on a Windows 7 machine at work -- I don't recommend Windows for this either, but that's what I have to work with there. I run PHP scripts from the command line (command prompt) all the time. I have even put a couple in the Task Scheduler.

[trq]

If you really must use Windows, I would recommend using vagrant to build a decent dev environment.
