help removing new line chars

[Aaron Collins]

Hello,

i have a string that was entered in a web form and stored in a mysql
database where the user entered carriage returns as well as <br>'s
after each line in the form. the data is stored as

line 1<br>
line 2<br>
line 3

i need is to modify the text so instead it reads

line1<br>line2< br>line3

the problem is when i use strpos() and substr() on the multi line
text, i keep getting these invisible \n chars that i can't seem to get
rid of. even after using trim($string), i still can't get rid of these
buggers.

is there a function in php that strips the invisible \n chars that are
generated from a web form?

Thanks so much for any suggestions :)

IIRC, web forms are supposed to submit line breaks as \r\n so what you can
do to ensure all are removed is something like so:

$text = str_replace("\r ", "", $text);
$text = str_replace("\n ", "", $text);

or the nasty one liner

$text = str_replace("\r ", "", str_replace("\n ", "", $text));

You can also do this:

$text = str_replace("\r \n", "", $text);

but if you do have any line breaks that are just "\n" then it won't get rid
of them.

Note that trim() only trims at the beginning and end of the string, not of
lines in the string, hence my solution.

or the elegant one liner :)

$text = str_replace(arr ay("\r", "\n"), "", $text);

Oh cool, I didn't know you could do that until you pointed it out. I guess
that's what I get for using PHP for such a long time. According to the
manual the ability to pass arrays was added in 4.0.5

The str_replace() worked!! Thank you so much for your help :) I was
really having fun with those suckers. I didn't know about the \r.
Thanks for taking the time and helping me out. I really appreciate it.

//strip newlines and leading spaces... logic from Smarty code (but, order reversed)
$strip_search = array('%[\r\n]+%m', // remove CRs and newlines
"![\t ]+$|^[\t ]+!m"); // remove leading/trailing space chars
$strip_replace = array('',
'');
$page = preg_replace($s trip_search, $strip_replace, $page);

The easiest way in my opinion is: strip_tags( $text);

This will strip all tags from the string.
