foreach won't work in a function

[tomandhannah]

I have the following statement in some code:

foreach ($rfields as $value) { echo "$value, "; }

This statement returns the values of my $rfields array separated by commas as expected. However, if I put this statement into the function below:

function tom() {
foreach ($rfields as $value) { echo "$value, "; }
}

But, when I call the function, I get an error: "Warning: Invalid argument supplied for foreach() in db.php on line 151"

Why would this work outside the function, but not inside the function? How can I fix it so that the function will print the values of the array separated by commas?

I see in your definition of the function that you are not passing the function the value $rfields. You can fix this by chaning your header to

function tom($rfields){ }

Then you will need to change your function call to:

tom($array);

That's it.

Hi,

above mentioned solution can be one option to do the task..
here is the another one

declare $rfields as global variable in ur function body

CODE:

function tom(){

GLOBAL $rsfields;

foreach($rfields as $value){echo "$value, ";}

}

Hope this will work for you..

Passing the parameter as an argument, dziman1229's method, is usually preferred.

Thanks! Works now... but now I have a different problem, which I'll post as a new thread...
