What exactly is this snippet of PHP checking for :
function checkOK($field) { if (eregi("\r",$field) || eregi("\n",$field)){ die("Invalid Input!"); } }

It is a function that takes a string variable. If that string variable contains a newline (\n) or a carriage return (\r) then the function will halt any further execution of the script and display the error message "Invalid Input!"
