special-characters

I'm trying to add some users to my Ldap DB but I get some errors (invalid dn syntax) when I use some special characters like ",.". I need a function that escape all characters. I try preg_quote but I get some errors in some cases. Thanks in advance Code: $user = 'Test , Name S.L'; if(!(ldap_add($ds, "cn=" . $user . ",".LDAP_DN_BASE, $info))) { include 'error_new_account.php'; } DaveRandom EDIT Jan 2013: added support for escaping leading/trailing spaces in DN strings, per RFC 4514 . Thanks to Eugenio for pointing out this issue. EDIT 2014: I added this function to PHP 5.6 . The code below is

I'm seeking simple Python function that takes a string and returns a similar one but with all non-ascii characters converted to their closest ascii equivalent. For example, diacritics and whatnot should be dropped. I'm imagining there must be a pretty canonical way to do this and there are plenty of related stackoverflow questions but I'm not finding a simple answer so it seemed worth a separate question. Example input/output: "Étienne" -> "Etienne" Reading this question made me go looking for something better. https://pypi.python.org/pypi/Unidecode/0.04.1 Does exactly what you ask for. In

I am currently writing a small script that checks the contents of each string. I was wondering what the REGEX would be to make sure that a string has a letter (upper or lower), a digit, and a special character? Here is what I know so far (whcih isn't much): if(preg_match('/^[a-zA-Z0-9]+$/i', $string)): Help would be great! Thank You! The easiest (and probably best) way is to do three separate checks with preg_match : $containsLetter = preg_match('/[a-zA-Z]/', $string); $containsDigit = preg_match('/\d/', $string); $containsSpecial = preg_match('/[^a-zA-Z\d]/', $string); // $containsAll =

I have added a section list for a simple Core Data iPhone app. I followed this so question to create it - How to use the first character as a section name but my list also contain items starting with characters outside A-Z, specially Å,Ä and Ö used here in Sweden. The problem now is that when the table view shows the section list the three last characters are drawn wrong. See image below alt text http://img.skitch.com/20100130-jkt6e55pgyjwptgix1q8mwt7md.jpg It seems like my best option right now is to let those items be sorted under 'Z' if ([letter isEqual:@"Å"] || [letter isEqual:@"Ä"] ||

For example, #'functionname , is it necessary? #'functionname in Common Lisp Common Lisp and some other Lisp dialects have more than one namespace. Here the ones for functions and values are different. To get the function value of a name, we need to write: (function functionname) Since that is a bit long to write, there is a shorter notation: #'functionname To show the effect see this: (let ((foo 42)) (flet ((foo () 'bar)) (list foo (function foo) #'foo (foo)))) Above defines a local variable FOO and a local function FOO . The list statement returns the value of FOO , then the function value

I want to check an NSString for special characters, i.e. anything except a-z, A-Z and 0-9. I don't need to check how many special characters are present, or their positions, I just need to know whether a particular string contains any or not. If it does, then I want to be able to display "Error!", or something similar. For example, jHfd9982 is OK but asdJh992@ is not. Also, letters with accents, diacritics, etc. should not be allowed. How would I go about this? Thanks! Michael NSCharacterSet * set = [[NSCharacterSet characterSetWithCharactersInString:@

I have a large filelist of 7000+ files to delete from a Unix directory. I could have accomplished this using a while loop while read file do rm $file done < filelist or just cat filelist | xargs rm The challenge comes from deleting those files which have "Windows-like back slash \, colon : and spaces " in their filenames. Eg. C:\Sxxx Accr Vac 1111.txt N:\Lxxx\Dxxx_FOLDER\Mxxx\Mxxx_DOWNLOAD_TEXTFILE_PATH\000000_Mxxx_Bxxx-Pxxx-H.txt N:\Lxxx\Dxxx_FOLDER\Mxxx\Mxxx_DOWNLOAD_TEXTFILE_PATH\130607_Mxxx_Bxxx-Cxxx-L.txt N:\Lxxx\Dxxx_FOLDER\Mxxx\Mxxx_DOWNLOAD_TEXTFILE_PATH\140103_Mxxx_Xxxx-Pxx-H.txt To
