directories

[angelorigo]

I have the following code to write on the screen the directory where the user is surfing on my website
<?

$root="http://www.website.com"; //site root
$url = explode("/", $PHP_SELF); //store each path in a variable
static $block; $counter = count($url)-1;
$n=1; //set internal loop counter value to 1 cause $url[0] is empty
echo "<a href='".$root."'>Home</a> > "; link inicial (array $url[0]

while($n<$counter){							$toc =$url[$n];						$block=$block."/".$toc;					echo "<a href='".$block."'>".$url[$n]."</a> > ";	
	$n++;		
}

?>

So i want to write for example, instead of "who" wich is the directory the user is acessing by the website "Who we are" i think using a switch this can be done, but this is not working:

<?
$root="http://www.website.com";
$url = explode("/", $PHP_SELF); static $block; $counter = count($url)-1; $n=1; echo "<a href='".$root."'>Home</a> > ";
while($n<$counter){ $toc =$url[$n];
switch($toc){
case $toc="who"; : $toc="Who we are";
break;
}
$block=$block."/".$toc; echo "<a href='".$block."'>".$url[$n]."</a> > ";
$n++;
}
?>

You're using the incorrect format of the switch. Here is the correct format (note the changes made on the case):
switch ($toc) {
case "who": $toc = "Who we are";
}

Rather than setting the case to $toc="who", we are setting the case simply to "who", as the switch is set to check $toc.

Thank´s Mordecai

Now is it working.

I switch the $url[$n], to write the path
since the $toc is used to build the link the path.

I hope this code can be useful to anyone.
I thought the path/link could be wrong but is it working fine writing "Who we are" and linking to "who"

while($n<$counter){			
      $toc =$url[$n];	

      switch($url[$n]){
         case "who" : $url[$n]="Who we are";
          break;
      }

$block=$block."/".$toc;				echo "<a href='".$block."'>".$url[$n]."</a> > ";
	$n++;		
}

?>

I've never seen switch being used if there is only one case to deal with. wouldn't some if condition do just as well?

Hi xblue

I have 20 directories to be switched, but just post one to work it out !
Now my doubt is: how time consuming this script will be now that it is switching 20 cases? at least i have not seen any diference. Do you think it will affect too much the performance?

sorry for the misunderstanding.

switching 20 cases shouldn't really be any problem I think.
actually someone else posted somewhere switch would be more efficient than doing the same thing as if-else construct.
