Trying to use eregi to check string for email injection

Recommended Posts

When I run this code below, it dies when the character r or n is encountered.  I only want it to die when there is a backslash and r or backslash and n together.  I have tried two backlsashes and that does not work either.

Does anybody know how I can fix this?

Thanks,
Kirka

function checkinjection($checkstring)
  {
if (eregi("\r",$checkstring) || eregi("\n",$checkstring)){
die("Problem Sending Email - MI");
}
}
