The PHP Page

The server page called by the JavaScript code is a simple PHP file called "gethint.php".


The code in the "gethint.php" checks an array of names and returns the corresponding names to the client:






// Fill up array with names
$a[]="Anna";
$a[]="Brittany";
$a[]="Cinderella";
$a[]="Diana";
$a[]="Eva";
$a[]="Fiona";
$a[]="Gunda";
$a[]="Hege";
$a[]="Inga";
$a[]="Johanna";
$a[]="Kitty";
$a[]="Linda";
$a[]="Nina";
$a[]="Ophelia";
$a[]="Petunia";
$a[]="Amanda";
$a[]="Raquel";
$a[]="Cindy";
$a[]="Doris";
$a[]="Eve";
$a[]="Evita";
$a[]="Sunniva";
$a[]="Tove";
$a[]="Unni";
$a[]="Violet";
$a[]="Liza";
$a[]="Elizabeth";
$a[]="Ellen";
$a[]="Wenche";
$a[]="Vicky"; //get the q parameter from URL
$q=$_GET["q"]; //lookup all hints from array if length of q>0
if (strlen($q) > 0)
{
$hint="";
for($i=0; $i {
if (strtolower($q)==strtolower(substr($a[$i],0,strlen($q))))
{
if ($hint=="")
{
$hint=$a[$i];
}
else
{
$hint=$hint." , ".$a[$i];
}
}
}
}

//Set output to "no suggestion" if no hint were found
//or to the correct values
if ($hint == "")
{
$response="no suggestion";
}
else
{
$response=$hint;
}

//output the response
echo $response;
?>





If there is any text sent from the JavaScript (strlen($q) > 0) the following happens:

1. Find a name matching the characters sent from the JavaScript
2. If more than one name is found, include all names in the response string
3. If no matching names were found, set response to "no suggestion"
4. If one or more matching names were found, set response to these names
5. The response is sent to the "txtHint" placeholder
