second issue first: one call to preg_replace...if you check out php.net/preg_replace, you'll see what i mean...use arrays... and as long as you have them ordered in the right way, it'll execute them in that order, so by the time the \s replace comes up all your 'bbbnbb' will be fixed...problem then is that those newlines would get caught by the \s and get switched to spaces...so, if you want them to stay, then use [ ] to represent a space instead of \s...might want [ \t] to catch tabs as well... first issue: hard to see whats going on, but check your syntax. i just ran this; $text = "this is some text with a newline in it right here \n there it was"; echo $text; echo '<br>'; echo preg_replace("/[ ]+\n+[ ]+/","\n",$text); and it made the substitution fine.

Using "\n" (either in single or double quotes) resulted in actual 'backslash n' being all over my output, instead of newlines. Hence, my inquiry. >your first pattern will be "/[ ]+\n+[ ]+/" with a replacement of a single >newline...then the second will be the previous regex.....check out php.net >for help with syntax and using arrays with preg_* functions....the first >should catch all situations of a series of spaces [with at least one newline >in between them] and substitute a newline..... Thanks, sounds about right. The second pattern (which sometimes includes getting rid of newlines) won't clobber the results of the first pattern? And are you suggesting two separate calls to the preg* function? It sounds like you are, if each of the two patterns also has a unique replacement string.
