Function

fnbcprog

I am very new to functions. This is actually the second time I have tried to use one. I am trying to create a function that prints the label and the url with the SessionID attached. I need some help under standing why this does not work.

reusable.php


function url($prefix,$page,$target,$sid,$label) {
     $url = "<a href='$prefix/$page?SessionID=$sid' target='$target'>" . $label . "</a>";
}

index.php

<tr>

<?
include reuable.php; 
url("","forgot.php","",$SessionID,"Forgot Password") 
?>

</tr>

do this:

function url($prefix, $page, $target, $sid, $label)
{
return $url = '<a href='.$prefix.'/'.$page.'?SessionID='.$sid.'&target='.$target.'>'.$label.'</a>';
}

And do this in your code:
$url = url(...);
echo = $url;

or simply:
echo url(...);

oh, don't forget you can global isht.
$someglobalvar ="I hate this non constant junk";
function blah(..)
{
global $someglobalvar;
return "blah ". $someglobalvar."<br>";
}

You can globalize the variable, but the use of global is really not recommended if you want your code to be as robust and clean as possible.

Usually it leads to poor programming.
