php wordwrap cut parameter when dealing with weird characters

阅读更多关于 php wordwrap cut parameter when dealing with weird characters

问题 I have a problem when using the wordwrap() function in php with for example chinese characters. When the $cut parameter in the wordwrap function is set to true, it ruins the string by inserting question marks. Is there a solution to this? 回答1: The native wordwrap function is not safe to use for unicode. Here's a mb_wordwrap by Sam B.: <?php /** * Multibyte capable wordwrap * * @param string $str * @param int $width * @param string $break * @return string */ function mb_wordwrap($str, $width

How can I make Firefox word-break with CSS?

阅读更多关于 How can I make Firefox word-break with CSS?

This is my code so far: <div style="width:100px;height:100px;background:red"> ssssssssssssssssssssssssssssssssssssss </div> However, word-wrap:break-word; word-break:break-all; does not prove useful, since it can't word-wrap on Firefox. What can I do, using CSS ? white-space: pre-wrap; /* css-3 */ white-space: -moz-pre-wrap; /* Mozilla, since 1999 */ white-space: -pre-wrap; /* Opera 4-6 */ white-space: -o-pre-wrap; /* Opera 7 */ word-wrap: break-word; /* Internet Explorer 5.5+ */ width:200px; The above piece of code works for me wonderfully Use the following rules together: /* For Firefox */

Calculating size of text before drawing to a canvas

阅读更多关于 Calculating size of text before drawing to a canvas

I'm using Delphi 7. I'm more than familiar with using a canvas and drawing text to a canvas, and also using TCanvas.TextHeight etc. The problem arises when I want to implement Word Wrap. Not only do I need the best way to draw text to a canvas and have it automatically wrap to a given width constraint, but I also need to know how high (or how many lines) it will be after it's wrapped. I need to prepare another image before I draw the text, an image which needs to be just big enough to place the wrapped text. This is an attempt to replicate how an iPhone displays SMS messages, with a baloon on

Where to wrap a line of code, especially long argument lists? [closed]

阅读更多关于 Where to wrap a line of code, especially long argument lists? [closed]

What's your preferred way of wrapping lines of code, especially when it comes to long argument lists? There has been several questions relating to wrapping lines (such as When writing code do you wrap text or not? and Line width formatting standard ), but I haven't been able to find one which covers where to wrap a line of code. Let's say we have a line of code that keeps going and going like this example: int SomeReturnValue = SomeMethodWithLotsOfArguments(Argument1, Argument2, Argument3, Argument4); How should that be wrapped? Here's a few ways I can think of, and some of their downsides:

Difference between hard wrap and soft wrap?

阅读更多关于 Difference between hard wrap and soft wrap?

I am in the process of writing a text editor. After looking at other text editors I have noticed that a number of them refer to a "soft" versus "hard" wrap. What is the difference? I can't seem to find the answer by searching. A hard wrap inserts actual line breaks in the text at wrap points, with soft wrapping the actual text is still on the same line but looks like it's divided into several lines. It's usual for text editors to auto-wrap text into paragraphs with hard newlines, but it's less common for the text to be re-flowed into a nice paragraph if you come back later and edit/add/remove

C#: Multiline TextBox with TextBox.WordWrap Displaying Long Base64 String

阅读更多关于 C#: Multiline TextBox with TextBox.WordWrap Displaying Long Base64 String

问题 I have a textbox to display a very long Base64 string. The TextBox.Multline = true and TextBox.WordWrap = true . The issue is caused by the auto-word-boundary detection of the TextBox itself. The Base64 string has '+' as one of the 64 characters for Base64 encoding. Therefore, the TextBox will wrap it up at the '+' character, which is not what I want (because the use might think there is a newline character around the '+' character). I just want my Base64 string displayed in Mulitline-mode in
