Function parameter question?

-Hi, I have this example of a php function from a textbook I鈥檓 using and have a general n00by question:



In the code:



<?php



function printBR($txt)

{

echo $txt."
";

}

printBR("This is a line");

printBR("This is a new line");

printBR("This is yet another line");



?>



Could $txt be referred to as an array?function printBR($i){

if(is_array($i)){

$c = count($i);

for($x=0;$x<$c;++$x){

echo $i[$x] . '<b' . 'r />'; // Yahoo Doesn't properly display br tags

}

}else{

echo $i . '<b' . 'r />';

}

}



Keep in mind though, that you won't see the keys to the array. If you want to see them, then substitute in:

echo '<pre>';

print_r($i);

echo '</pre>';

Directly echoing an array won't give you the results you want.

You would need to loop through the array and print each element:



$num = count($txt);

for ($i=0; $i<$num; $i++) {

echo $txt[$i] . "\n";

}
