removing spaces and line breaks - php
I'm trying to find away to remove multi spaces from within a string (trim() only does start and end), also a fool proof way of removing adjusting multi line breaks.
example:
This old dog
has
fleas.I want to allow one \n for sentence and max of two \n's for paragraph, problems arise when there is more than three, unless I place it in a while loop which I'd rather not do if I can help it.
for the spaces tried str_replace(" "," ",$theinput) but it messes up the line breaks - need to display as nl2br on output
Anyone done anything like this before?

Well....if you're html-ifiying this...it could turn out that your input is:
This old dog<br />has<br />
<br />
<br />
fleas
So in that instance, you would want to search for the HTML components, and not the PHP line break or blank space.

Thanks but I'm not "html-ifiying" it, comes from a form into a database, but need to strip spaces etc before going in, then when displayed am using nl2br()

well why don't you try doing nl2br() first, and then searching for the 's...see if that works, just to see if your logic is correct.

Thanks but been there done that,
Biggest problem is if there are say six 's, ideally it should be cut down to two str_replace("\n","",$theinput);
I have to do several combinations, , \n, \n\r etc
Something I'm thinking of trying is to strip all double spaces out " " and adding a \n after a full stop. Down side is if the full stop isn't used it wont work as intended
also if a measurment is used, ie. 12.5 mm
