for the first case - using "\n", try :
ereg_replace('\n+', '\n\n\n', $str)
for the second case - using "<br>", try :
eregi_replace('(<br>)+', '<br>', $str);

Subject: [PHP] Need regular match help - possibly
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 <br><br><br><br><br> a test.
I would want it converted to
This is <br><br><br> 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!
