Array call from Function

[rkitect]

OK... so I have this snippet of code:

$familyName=Gibsons;
$col=0;
while (isset($family[$familyName][$col])) {
	echo $family[$familyName][$col].' Gibson<br>';
	$col++;
};

that works fine and my output is:

Carl Gibson
Joanna Gibson
Pepper Gibson
Ben Gibson
Allison Gibson
Gwen Gibson
Bennie Gibson

I get all the values of the nodes in the 'Gibsons' array to output fine.

However, when I do this:

function printFamily($familyName) {
	$col=0;
	echo $familyName;
	while (isset($family[$familyName][$col])) {
		echo $family[$familyName][$col].' Gibson<br>';
		$col++;
	};
}

printFamily(Gibsons);

All I get to output is:

Gibsons

What am I mising here?

Thanks in advance!

Read up on variable scope.

Thanks Installer. Not only did that fix it but I now have (2) solutions that I would like to pass along for anyone else having that problem.

You can either pass the variable into the function when you call the function:

function printFamily($familyName, $famArray) {
	$col=0;
	if (! empty($famArray[$familyName])) {
		echo $familyName."s<hr />";
		while (isset($famArray[$familyName][$col])) {
			echo $famArray[$familyName][$col]." $familyName<br>";
			$col++;
		};
	} else {
		echo "$familyName does not exist.  Please try again.";
	};
	echo '<hr />';
}

printFamily(Gibson, $family);

or you can set the variable in question as a global within the function:

function printFamily($familyName) {
        global $family;
	$col=0;
	if (! empty($family[$familyName])) {
		echo $familyName."s<hr />";
		while (isset($family[$familyName][$col])) {
			echo $family[$familyName][$col]." $familyName<br>";
			$col++;
		};
	} else {
		echo "$familyName does not exist.  Please try again.";
	};
	echo '<hr />';
}

Good luck!
