Understanding the Question Mark and Colon Operators in Conditional Expressions
The question mark and colon operators, "?" and ":", serve as part of the ternary conditional operator, commonly referred to as the "ternary operator." It provides a concise alternative to the traditional if-else statement.
Syntax:
boolean_expression ? true_result : false_result;
Usage:
The expression starts with a boolean expression that evaluates to true or false. If the expression is true, the ternary operator returns the value of the expression after the question mark. Otherwise, it returns the value after the colon.
For example:
<code class="java">int result = a > b ? x : y;</code>
This statement is equivalent to the following if-else statement:
<code class="java">if (a > b) { result = x; } else { result = y; }</code>
Applications:
The ternary operator is particularly useful in situations where you need to conditionally assign a value or perform a single line of conditional processing. For more complex conditional logic, it is still recommended to use if-else statements.
Example Code:
Consider the following code snippet:
<code class="java">int row = 10; int column; while (row >= 1) { column = 1; while (column "); ++column; } --row; System.out.println(); }</code>
In this example, the ternary operator is used within the print statement to conditionally print "" otherwise.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
