I decided to follow step No3 although i dont know any php :)
The closest solution i came up with is the following, please correct my mistakes
This is the function that i want to make a php module out of it so every php script can easily invoke the php module: This is just the function i dont know how to make it a php module...

<?php

function counter($pagename,$db,$host) {
    preg_match("{([^/\\]+?)(?:\.[^/\\.]+)?$}", $pagename, $matches); l
+ist($pagename) = $matches;
    
    //======= Insert or Update pagecounter appropriately, then display
+ it ========
    @$db->do('INSERT INTO counters (pagename, pagecounter) VALUES (?, 
+0)', null, $pagename);
    
    if ($host != 'webmaster') $db->do('UPDATE counters SET pagecounter
+ = pagecounter + 1 WHERE pagename = ?', null, $pagename);
    
    list($counter) = $db->selectrow_array('SELECT pagecounter FROM cou
+nters WHERE pagename = ?', null, $pagename);
    
    return $counter;
}

?>

...and after the creation of the module i will have to invoke it as follows(iam sure i have errors)

$file = $_SERVER['SCRIPT_FILENAME'];
$host = $_SERVER['SERVER_ADDR'];

$db = mysql_pconnect("mysql1.000webhost.com", "a3310457_counter", "a33
+10457_akis", "*****"); #i changed host and details here

$counter = counter( $file, $db, $host );
