Also I am trying to set up a search feature, how do I make direct the search a specific database?

<?php

function one() {
//Your code here
}

function two() {
//Your code here
}

function three() {
//Your code here
}

switch($op) {

case "one":
one();
break;

case "two":
two();
break;

case "three":
three();
break;

default:
one();
break;
}

?>

Linking Examples:


http://mysite.com/myfile.php?op=one
http://mysite.com/myfile.php?op=two
http://mysite.com/myfile.php?op=three


The default page will be fuction one.

Or u can try this:


<?php

if(!isset($id)){
die("Id not set");
} else {


//Your code goes here.

}

?>

do i need to put that in every document? And what does the "switch" tag do when it makes it past #3?

Best way is to use a database. Will be more efficiant too if you've got loads of files/pages.

On the example above, once you get past 'three' it'll go to the default page, ie: one.

So if you've got hundreds of pages, you'll have hundreds of 'case's in a switch, which wouldn't seem resourceful to me. Best way if you don't have a db is probably to use an array:

http://uk2.php.net/array

Then check if the page is in the array by using

http://uk2.php.net/in_array


/* security checks done, connected to db etc etc */
$sql = "SELECT data FROM table WHERE id='$id'";
$query = mysql_query($sql) or die(mysql_error());
if(mysql_num_rows($query) == '1'){
echo 'Page found, echo all info from db entry';
}else{
echo 'Page not found, show error';
}
