Seems like mbstring function is borked in 4.2.3 :) 

mb_ereg_match doesn't seem to be returning a proper FALSE value when passed to a conditional statement.

BUT, the return value is an empty string which *should* evaluate to flase no?

Following output and code illustrate:

OUTPUT:

RETURN was ** 
a is FALSE

CODE:

if (mb_ereg_match("A", "X")) {
 echo "MATCHES <BR>";
} 
else {
  "echo NO MATCH <BR>"; 
}
$a = mb_ereg_match("A", "X");
echo "RETURN was *$a*<BR>";
if ($a) {
}
else {
 echo "a is FALSE<BR>";}
exit;

Just a comment.

When you submit bug. Submit with "complete" script that is possible to copy & page, then execute.

It will speed up bug fix.

I think you may have meant with the line
  "echo NO MATCH <BR>"
for
  echo "NO MATCH<BR>";

But I can not reproduce the problem yet.
Can you give us a more accurate script to confirm the bug?

Hint: var_dump( mb_ereg_match( ... ) ); will do it easier.

Sorry! Bogus bug ...

I had quotes around my whole echo statement as you pointed out .... really sorry.
