escaping

I'm trying to mimic the json_encode bitmask flags implemented in PHP 5.3.0, here is the string I have: $s = addslashes('O\'Rei"lly'); // O\'Rei\"lly Doing json_encode($s, JSON_HEX_APOS | JSON_HEX_QUOT) outputs the following: "O\\\u0027Rei\\\u0022lly" And I'm currently doing this in PHP versions older than 5.3.0: str_replace(array('\\"', "\\'"), array('\\u0022', '\\\u0027'), json_encode($s)) or str_replace(array('\\"', '\\\''), array('\\u0022', '\\\u0027'), json_encode($s)) Which correctly outputs the same result: "O\\\u0027Rei\\\u0022lly" I'm having trouble understanding why do I need to

I have to run a command in the background but I want to have proper escaping for its parameter. system("rake send_mails subject='#{params[:subject]}' 2> /dev/null 1> /dev/null &"); If I write system("rake", "send_mails", params[:subject]) then I don't have "place" for redirections and the & sign. If I don't I do not have escaping for the subject parameter. How can I resolve this? In Ruby 1.9, try Process.spawn : # Spawn a new process and run the rake command pid = Process.spawn({"subject" => params[:subject]}, "rake", "send_mails", :out => 'dev/null', :err => 'dev/null') # Detach the spawned

I need to send HTML emails directly from oracle PL/SQL package. This works almost fine.

So, I need to escape this column before inserting into email body. Is there a function to escape html special chars into entities automaticly? Or do I need to replace('<', '<', string) manually all the special characters? You can use the htf.escape_sc function: SQL> select htf

This question already has an answer here: XSS prevention in JSP/Servlet web application 8 answers I have this weird issue with special characters. In JSP, I am using field name as id and the name can be anything like id="&lt;1 and &>2" (OR) id="aaa & bbb" I don't have any other option to use ID's other than names, that what the only thing I get from backend.

I'm wanting to match ^(@|\s)*{{string}}:? whereas {{string}} is dynamically defined. It may have periods and dashes and any number of things in it and I really need for it to be escaped.

I was wondering if Go provides any sort of analog. donatJ regexp.QuoteMeta does the deed. 来源： https://stackoverflow.com/questions/27415532/any-way-to-escape-a-go-string-in-a-regular-expression
