escaping

问题 JSON-LD fields are supposed to be double quoted "name": "value", but what if the value has an embedded double quote, like "name" : "Magnetic Strip (36" Length)" Is it sufficient to escape the double quote "name" : "Magnetic Strip (36\" Length)" or is there a better way? 回答1: Yes, backslashes have to be used for escaping double quotes in string values: A string is a sequence of zero or more Unicode characters, wrapped in double quotes, using backslash escapes (if necessary).

问题 So I do this: <?php session_start(); include("../loginconnect.php"); mysql_real_escape_string($_POST[int]); $int = nl2br($_POST[int]); $query = "UPDATE `DB`.`TABLE` SET `interests`='$int' WHERE `user`='$_SESSION[user]'"; mysql_query($query) or die(mysql_error()); mysql_close($con); ?> And let's say that $_POST[int] is "Foo' bar." The single-quote remains unescaped AND I get a MySQL error when running the script, due to the quote. What's wrong? 回答1: m_r_e_s() RETURNS the escaped value, it

问题 I'm currently running into issues when searching for entries where the DN contains a comma: StringTokenizer st = new StringTokenizer(dn, "="); Attributes searchAttributes = new BasicAttributes(st.nextToken(), st.nextToken()); Enumeration results = ctx.search(baseDn, searchAttributes); if (results.hasMoreElements()) { // ... } I tested both dn=first,second as well as dn=first\,second , and although the search runs correctly, I never get any results back . The same baseDn and dn works correctly

问题 I have a string: " \" " . I would like to escape all unescaped double-quotes, i.e. add a backslash before " if it's note there. input = '" \\" "' input.replace(???) == '\\" \\" \\"' I've tried input.replace(/(?!\\)"/g, '\\"') It escapes second backslash twice ( '\" \\" \"' ) for the reason I don't understand. I've figured out (' ' + input).replace(/([^\\])"/g, '$1\\"').slice(1) But it looks ugly. It has to be a better way. Update: One more test case: >> input = '" \\" \\\\" \\\\\\"' -> '" \"

问题 I have some awk that rearrange a line. I would like to escape one of the variables (e.g. $_), in such way that " and \ are escaped with a backslash. Example: echo "Ehm, \"hi\", he \\ said" | awk '{$1="" ; print "\"" $_ "\"" }' " "hi", he \ said" (do not change the echo, normally I read from a file that has Ehm, "hi", he \ said in it). I would like to have " \"hi\", he \\ said" instead. How can I do this? Is there a function in awk that can do this? 回答1: Is there a reason you resort to awk?

问题 For some reason, all my quotes are being escaped and displayed as \". Previously, it was okay. Then I looked at phpinfo() and saw that my magic_quotes_gpc is turned on. However, I cannot find the directory /usr/local/lib/ where php.ini file is and I cannot edit my .htaccess file (gets 500 Internal Server Error). I tried putting this instead on top of my scripts file (which is included in all pages): if (get_magic_quotes_gpc()) { $process = array(&$_GET, &$_POST, &$_COOKIE, &$_REQUEST); while
