Accessing Variables Within A Function

[iceman2g]

This is probably a simple question but not quite sure how to access a function set within a variable.

Here's what I mean.

function welcome_Message() {

$variable = "Welcome";
}

the above code is saved within a file and at top of my page I have include("filename.php");

You can pass it into the function e.g.

function welcome_Message($variable) {
  $variable = "Welcome";
}

//pass to welcome_Message
welcome_Message($myvar); //depending on its name

Or you can use global, i dont recommend unless you only plan to use the function in one situation and will remember in case you change variables names etc

function welcome_Message() {
  global $variable;
  $variable = "Welcome";
}

I've been trying global, btu haven't been able to get it working. Hence why I am asking.😕

[planetsim]

Well what errors are you getting. To use global the variable must exist prior to use of the function.

[iceman2g]

I'm recieving no errors. The variable is created with the function.

do you mean access the varible inside of the function?

and if so just return it 🙂

function welcome_Message() {

$variable = "Welcome";
return($varible);
}

this will return the varible(display it) and for your thing about gobals im guesing that you have globals turned off

Duh :rolleyes:

Ok i'm trying to return several variables so that I can use each in various parts of my code.

OK here's the code I was using before.

echo"<option value=\"$option\">$option$price</option>";

I'd call my fucntion and have my drop down menu already created, nice but not what I want. I want to return $option and $price so that I can create the drop down menu on the new page and use each variable in other areas.

You can only return one value whether that be a normal variable or an Array. One result can only be return no more. Of course you can have different returns in sections of the function but the same rule applies.

Just for a word of advice you dont require the parenthesis around the return just like echo and print.

[iceman2g]

Well that's not good.

I need to someway split that data up so I can use the $option and $price elsewhere in my code.

Any idea how I might do this.

[planetsim]

Why not use an Array. That way you can later split it up.

Im am a consistent coder, everything i do i put it in () and quote unless you cant.

[iceman2g]

What an easy way to split this up.

<option value=\"".$option."-".$price."\">".$option." $".$price; if ($t==1){ echo $pp; }echo"</option>

I'd like to use $option and $price. So I need to split it up.

BTW thanks for all the help guys.🙂

any suggestions?
