In regex, ^ and $ shoudl match start/end of a line when the 'm' /multiline
modifier is set -- however I just spent the better part of the day trying
to figure out why it wasn't working as expected. I used the query
test$
....and the text
test
test
test
Only the last instance of test would match -- that is expected without the
multiline flag. ( http://tinyurl.com/dx86w ) however they should each
match with the multiline flag so long as there's no additional whitespace
after the fact ( http://tinyurl.com/7bap6 ).
Finally, out of ideas, I replaced \r\n with \n on all of my _POST data --
and presto, it worked. So, my question is -- why won't it work on data
with windows line endings? Is there a built in function for changing the
line ending style or something? It seems there should be a more elegant
solution than running a find/replace on all of my user-input just to make
sure the line ending style are liked by PCRE.
Thanks

Allen, I've never encountered such problem because I normally
clean up all "\r" characters, whenever I encounter them,
but there is a parameter "auto_detect_li ne_endings" in your php.ini
which is normally set to "Off".

That'll probably do it. In my code, I never use \r -- the problem was
from user-input, which hadn't occurred to me to manually clean up. Thanks
much. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

Hi,
I've made this regex to catch the start of a valid multiline comment such as
"/*" in e.g. T-SQL code.
"(?<=^(?:*'*')*?*)(?<!^(?:*'*')*?--.*)/\*.*?$"
With Multiline option on.
As we know the T-SQL single line comment starts with a "--" and the string
character is a "'".
Considering all this, from these lines below the pattern will only catch "/*

Hello all,
I'm handling some text files where I don't (necessarily) know the
encoding beforehand. Because I use regular expressions to parse the
text I *must* decode UTF16 encoded text (otherwise the regexes split on
byte boundaries).
I can recognise UTF8 and BOM and remove (but not necessarily decode).
For UTF16 it seems that the Python codec will automatically remove the
BOM. Having detected it (to trigger a decode) is it considered

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
