Hello Gaylen,

try this:

$string = preg_replace(/\n{3,}/, \n\n\n, $string);

 I need a routine that will allow me to trap multiple br and/or line feed
 characters and convert them to a constant number.  As an example, let's
say
 that you have text that has 10 carriage returns and/or line feeds.  I want
 to limit this to 3.  So, I need to be able to parse the line to detect the
 multiple control characters and convert the string to 3.  So if the string
 looked something like:

 This is \n\n\n\n\n\n\n\n\n\n a test.

 I would want it converted to

 This is \n\n\n a test.


 Conceivably, it could be

 This is brbrbrbrbr a test.

 I would want it converted to

 This is brbrbr a test.


 I know I could write a do/while loop, but I was wondering if there is a
way
 using eregi_replace or something along that line?

 Thanks!

Thinking about it, this would probably be even better:

$string = preg_replace(/(\n|br){3,}/i, \\1\\1\\1, $string);

This:
$string = This is a
\n\n\n\n\n\n\n\n\n\n\ntest\nTesting\nTesting\n\n123brbrbrbrbrbr
brbrbrbrbrSome more testingbrbrbrbrbrbrbrbrbrAnd
a little
morebrbrbrbrbrbrbrbrbrbrbrbrbrbrbrbrbrbr
brbrbrbrbrbrbrbrbrbrbrbrbrbrEven more.;

Then outputs as this:

This is a br /
br /
br /
testbr /
Testingbr /
Testingbr /
br /
123brbrbrSome more testingbrbrbrAnd a little
morebrbrbrEven more.

when echo'd with nl2br()

As a side note, does anyone know what's with the br tag changing to br
/?  That's the way I've always used the line break tag for wml pages, but
hadn't realised that it's being written that way for standard html now. Is
this a change in spec?

Thanks.  According to the manual, the br / is for XHTML compliance.  This
changed in 4.0.5.
