Using correct regex would help:
ereg_replace("[[:cntrl:]]", "*", $str);

Description:
------------
I was handling some broken text file. And I managed to fix it by
replacing the ascii-control characters (0x00 to 0x1F) to avoid crash
when INSERT the text into a db-table.
But the ereg_replace replaces other critical characters such as 0-9 : <
= > ... (seems to be 0x30 to 0x3F), too.
Reproduce code:
---------------
$str = "<a href='http://www.php.net/'>PHP.net</a>";
$result = ereg_replace("[\\x00-\\x1F]", "*", $str);
// the result was:
// *a href*'http*//www.php.net/'*PHP.net*/a*
// not,
// <a href='http://www.php.net/'>PHP.net</a>
Expected result:
----------------
the function should replace only the characters ranging 0x00 ~ 0x1F
only.
Actual result:
--------------
it replaced not only 0x00 - 0x1F but also 0x30 ~ 0x3F (I guess, and
0x20 ~ 0x2F seems to be safe)
