<?php
function sanitize($data); {
     return mysql_real_escape_string($data)
}
?>

I'm getting this error while opening my sites index.php

Unnecessary and incorrect semi-colon:

function sanitize($data); <-- HERE

Missing semi-colon:

return mysql_real_escape_string($data) <-- HERE

Correct code:

<?php
function sanitize($data) {
     return mysql_real_escape_string($data);
}
?>

function sanitize($data); {
                        ^--- extra semicolon as well

Remove the semi-comma here function sanitize($data);
And add the semi-comma at the end of return mysql_real_escape_string($data)

The corrent code is:

<?php
function sanitize($data) {
     return mysql_real_escape_string($data);
}
?>
