variables

问题 I am using PHP , Zend Framework and Zend_Translate (gettext adapter). To edit translations I use POEdit which utilizes xgettext to fetch strings to be translated. POEdit (xgettext) will search for keywords to find strings to translate. So, if searching for the keyword translate , POEdit will have no problem finding the 'Text to translate' string when the text is passed to the translate function directly like: echo translate('Text to translate'); But, in ofther cases strings will be passed to

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 5 years ago . I have nearly finished my game (just graphics and this to do) but do not know how I can save high scores. I searched corona's apis but did not manage to find what I needed. I also downloaded this http://techority.com/2011/12/28/ego-easy-saving-and-loading-in-your-corona-apps/ but

问题 I have a recursive function that can produce a difficult-to-know number of expressions, each needing a new variable multiplied to it. These variables will later be removed out by calculations involving integration or residue. How can I develop these unknown number of variables? Maybe indexed? All examples I've seen on the internet are working with an a priori known object of a definite size, e.g. "item" in How can you dynamically create variables via a while loop? or Accessing the index in

问题 There are many questions asking about how to use a variable within a sed pattern, for example: sed "s/re/$VAR/" file , but I want to perform a substitution on a variable. So far, I have been using echo to do this: echo "$VAR" | sed 's/re/new/' But, though this works, it seems messy. Is there a simpler/more elegant way of doing this in bash or zsh? 回答1: You can do it like this: sed 's/re/new' <<< "$var" If you want to do that and update the variable you can do this: var=$(sed 's/re/new' <<< "

问题 I'm a little confused exactly about how polymorphism and extending classes etc... works in Java when creating objects from these classes. I recently had a problem which someone on here helped me resolved (see Not able to access object sub class's variable? (Java / Android)) for background. I was attempting to create an object like so: Quad hero = new Hero(); Where Hero was a subclass of Quad(); I had variables in my Hero class which I wasn't above to access. The solution was to change my

问题 I am currently working on a JavaScript project and know that JavaScript source code is accessible through the browser. In the code, I have a variable that stores a secret string that is used by the program. However, I do not want others to view the source code and find out the value of this variable. Is there a way to hide the value of a variable? Or is it possible to change the variable value after? For instance, change the actual source code to set the variable to a different value? This

问题 This question already has answers here : What does *& mean in a function parameter (5 answers) Closed 6 years ago . I found this in a final exam: int a = 564; int* pa = &a; int *& pr = pa; cout << *pr; According to the multiple choice answer, the code is valid, and displays the value of a. But I'm confused about evaluation and precedence for line 3. Order of operations for C states that * and & have the same order. So, would it then be int *(&pr) ? How can this be described in words? Thank

问题 I am trying to do a check before the data inserts into the MySQL query. Here is the code; $userid = ($vbulletin->userinfo['userid']); $sql3 = mysql_query("SELECT * FROM table WHERE ID='$_POST[hiddenID]'"); while ($row = mysql_fetch_array($sql3)){ $toon = $row['toonname']; $laff = $row['tlaff']; $type = $row['ttype']; if ($type == 1){ $type == "Bear"; } elseif ($type == 2){ $type == "Cat"; } elseif ($type == 3){ $type == "Dog"; } } However, this isn't working. Basically, there are different
