I am stuck on the following... I would like to get some text from a user and then input that as a variable.

$a = "$input";

If the user types a word starting with a dollar sign ($), I get an error, saying that the variable does not exist... Any ideas on how to filter the dollar sign out?

Thanks,

dombi

Um... try:

$a = $input;

[nonhuman]

$a = $input; will just set a variable called $a to the same value as a variable named $input, it won't actually get the input from the user.

How are they inputing the information? Is it a web form, or just at the terminal?

If it's a web form, then the information they enter will be stored in either $_GET or $_POST depending on the submission method you're using. So if the input box was named "foo" on the web form, you would do $a = $_GET["foo"] or $a = $_POST["foo"].

If it's at the terminal... I'm not actually sure. Why would you use PHP at the terminal?

Where does he mention 'terminal'?

$name = $_GET["Name"]
$name = $_POST["Name"]

Is correct, but $a is a bad variable, can't you come up with something more understandable?

He didn't say anything about the terminal, but he also didn't say anything that would make me think it was for a web page. So I figured I'd cover all the bases as best I can. As his sig says he's a web designer and PHP isn't a language that most people would choose for programming outside a web environment I wasn't too worried that I had no idea how to get input from the command line in PHP.

And $a was his variable name not mine. I was just using his example.

I know about the variable name, I think I should have been clearer in my response, and I actually was directing it towards him. Sorry for the confusion, I was not critiquing your code.

Right about the web / php... conclusion.

Yeah - the lounge - *great* place to post PHP questions.

The webDev forum must be for posting stories about badgers and things.

[Ghoser777]

Better than what's usually posted in the lounge.

And amazingly, this thread has yet to see any use of the "Ha! Ha!" picture.

Um.. original question is:

"If the user types a word starting with a dollar sign ($), I get an error, saying that the variable does not exist... Any ideas on how to filter the dollar sign out?"

Not how you read in the user's input.

[hyteckit]

If the question was how to you get the user input, then I would have to ask how is the user inputting data.

Is the coming from command line?
From a web form? GET or POST method?
What's for form field name?
Is global variables turned on?

BAH!

Use WebObjects, it's free now. And drag'n'drop is just so much more fun



(I know - not much help, but one has to spread the good word, right?)

[King Bob On The Cob]

well, there is always the good ol eregi_replace...
eregi_replace("\$", "", $input);
not sure if that's gonna do it for you, but it should.

Ah, whoops. Sorry bout that.

That's cool. A lot of us are not very quick these days, and I've missed a few admittedly and have had to have a bit of crow myself.
