Variable & Function

[Anon]

Im a bit clueless on this one, so maybe someone can help me out.

I have a variable that has a value. That value is the name of a function.

I want to be able to take $myvar and run the appropriate function based off of its value.

Example:

$myvar = "somefunction";

function somefunction()
{
do something here
}

Any ideas how I would go about doing this?

Thanks,

Derek

I'm not quite sure of what you're talking about, but if you have a variable and want to use it in a function simple create function like this:

function somefunction($somevar) {
do something with $somevar // must be somevar because this isn't global, if you had specific variable to use, you'd use global $variable_name;
}

and then create variable such as $myVar = "whatever"; and do this to use $myVar in somefunction,

somefunction($myvar);

for example, echo 2 strings:

function echotwo($varone, $vartwo) {
echo $varone.' and '.$vartwo;
}

and then:
$textone = "PHP";
$texttwo = "mySQL";

echotwo($textone, $texttwo);

would echo PHP and mySQL

or should do that 🙂

Hope it helps, Arni

Well here is a better description.

$var = "bob";

Now $var has the value of bob. Whatever the value of $var is the name of a function.

So since $var is bob, i want to run the function bob()

Summary. I want to take the value of a variable and run a function off of the variables value.

So if $myvar has a value of dosomefunction

then i want to run the function

dosomefunction();

How do i go about this?
