case-insensitive

I have seen many times in htaccess these type of rules : RewriteCond %{HTTP_REFERER} !^http://www.domain.it$ [NC] or RewriteCond %{HTTP_HOST} !^www\.domain\.it$ [NC] Why is the NC flag necessary, when checking only the domain part? I noticed browsers always converts uppercases in domain names into lower cases , so I don't see what the [NC] flag is usueful for in this case. I mean if we check the remaining part of the url I understand the need for [NC] flag cause on Unix systems www.domain.com/index.html is different file than www.domain.com/INDEX.HTML but I don't understand the need of NC flag

I have the following data in a Table PriceOrderShipped PriceOrderShippedInbound PriceOrderShippedOutbound In SQL I need to write a query which searches for a string in a table. While searching for a string it should ignore case. For the below mentioned SQL query SELECT DISTINCT COL_NAME FROM myTable WHERE COL_NAME LIKE '%PriceOrder%' gives all the above data, whereas SELECT DISTINCT COL_NAME FROM myTable WHERE COL_NAME LIKE '%Priceorder%' doesn't give. Eg. when I search for 'PriceOrder' or 'priceOrder' it works but 'priceorder' or 'Priceorder' doesn't work. I have tried with the below query

I'd like to search for an upper case word, for example COPYRIGHT in a file. I tried performing a search like: /copyright/i # Doesn't work but it doesn't work. I know that in Perl, if I give the i flag into a regex it will turn the regex into a case-insensitive regex. It seems that Vim has its own way to indicate a case-insensitive regex. Chinmay Kanchi You need to use the \c escape sequence. So: /\ccopyright To do the inverse (case sensitive matching), use \C instead. As well as the suggestions for \c and ignorecase , I find the smartcase very useful. If you search for something containing

I have made a small script designed to find a string and wrap it in a span. The string is stored in a variable. The HTML <h2>I have a lot of friends.</h2> <h2>My best friend's name is Mike.</h2> <h2>My best friend's website is <a href="http://www.myfriendmike.com">myfriendmike.com</a>.</h2> The jQuery var term = "friend"; var item = $("h2"); $(item).each(function() { var itemHTML = $(this).html(); var newItemHTML = itemHTML.replace(term, '<span class="highlight">' + term + '</span>'); $(this).html(newItemHTML); }); Here is the entire thing put together: http://jsfiddle.net/97hxbyy0/ The script

I'm looking for a MySQL collation for UTF8 which is case insensitive and distinguishes between "a" and "ä" (or more generally, between umlauted / accented characters and their "pure" form). utf8_general_ci does the former, utf8_bin the latter, bot none does both. If there is no such collation, what can I do to get as close as possible in a WHERE clause? My recommendation would be to use utf8_bin and in your WHERE clause, force both sides of your comparison to upper or lower case. It works fine here with utf8_german2_ci as collation: SELECT * FROM tablename WHERE fieldname LIKE "würz%" COLLATE

I want to do typical highlight code. So I have something like: $valor = preg_replace("/(".$_REQUEST['txt_search'].")/iu", "<span style='background-color:yellow; font-weight:bold;'>\\1</span>", $valor); Now, the request word could be something like "josé". And with it, I want "jose" or "JOSÉ" or "José" etc highlighted too. With this expression, if I write "josé", it matches "josé" and "JOSÉ" (and all the case variants). It always matches the accented variants only. If I search "jose", it matches "JOSE", "jose", "Jose" but not the accented ones. So I've partially what I want, cause I have case

Thanks to the help with my previous homework question Regex to match tags like <A>, <BB>, <CCC> but not <ABC> , but now I have another homework question. I need to match tags like <LOL> , <LOLOLOL> (3 uppercase letters, with repeatable last two letters), but not <lol> (need to be uppercase). Using the technique from the previous homework, I tried <[A-Z]([A-Z][A-Z])\1*> . This works, except there's an additional catch: the repeating part can be in mixed case! So I need to also match <LOLolol> , <LOLOLOlol> , because it's 3 uppercase letters, with repeatable last two letters in mixed case. I

I found in this article , that since ORACLE 10g, there is a way to make a particular connection-session compare strings case-insensitive, without needing any crazy SQL functions, using an ALTER SESSION . Does anyone know if, in 11g, there might be a way to make the database to always operate in this mode by default for all new connection-sessions, thereby eliminating the need for running ALTER SESSION s every time you connect? Or perhaps, an additional parameter you could specify on your connection string that would turn the same on? You could just set the NLS_SORT , NLS_COMP parameters
