问题 I know that similar questions have been asked on Stack Overflow many times, but I am having problems with triple nested quotes in html/php.

Here is what I am trying to do (this is found in a php file): echo"<div id = 'feed-element'> <button class='username-button' type='button'>@".$currentUsername."</button> <button class='hashtag-one-button' type='button'>".$hashtag_one."</button> <button

问题 I want to preserve single or double quotes around html attributes, specifically for innerHTML within the content editable div. I know this is weird requirement, but I am looking for possibilities. So lets say I put html in content editable div from server : <div class="editable"> PRESS MENU BUTTON<img src='BUTTON_BACK.png' vspace='-16' width='32' height="32"> </div> This should be preserved. But currently in firefox, as I inspect the DOM it just converts all single quotes to double quotes

问题 I have a function where users can pull a record searching by a text field. The input is put into the following SQL query: $db->query("Select * from users where name = '".$db->real_escape_string($posted_var)."' limit 1"); $db is a mysqli connection object Works perfect until I have a ' in the name.. then the user is required to manually escape the quote to get it to match........ Shouldn't the real_escape_string() function do that for me? I have a test record where name is "test\'string" in

问题 (This is a more specific version of the problem discussed in bash - expand arguments from array containing double quotes .)

问题 I am trying to learn the best way to write queries. I also understand the importance of being consistent. Until now, I have randomly used single quotes, double quotes, and backticks without any real thought. Example: $query = 'INSERT INTO table (id, col1, col2) VALUES (NULL, val1, val2)'; Also, in the above example, consider that table , col1 , val1 , etc. may be variables. What is the standard for this? What do you do? I've been reading answers to similar questions on here for about 20

问题 I've got to write a single-input module that can convert decimals to Bukiyip (some ancient language with a counting base of 3 or 4). For the purpose of the assignment, we only need to work with base 3. I've written some code that does this, but it returns my Bukiyip number with quotes, leaving me with an answer such as '110' for 12. Please help me understand how to work around this? I'm new to Python and keen to learn so explanations will be really appreciated. def bukiyip_to_decimal(num):

问题 In c#: I need to create oracle query string like this: string orQr = @" SELECT ""Date"", ""Key"" FROM TBL "; I need to do it dynamicly. But there is a problem with escaping double-double quotes.

问题 While using IntelliJ Idea to code Scala I've noticed it to use to offer to enclose a string literal in a second pair of double quotes. «Convert to """string"""» - it says. If I agree - it just adds a 2 more double quote marks before and 2 more after the string, having my string to look like val myString = """my string value""" How does this make any sense? Do triple double quotes mean something special in Scala? 回答1: With IntelliJ smart String, there should be only two cases. simple string
