PHP: Incrementing Decrementing Operators
PHP supports C-style pre and post increment and decrement operators. The Increment/decrement operators operate only on variables and not on any value.
List of increment/decrement operators
|++$x||Pre-increment||Increments $x by 1, then returns $x.|
|$x++||Post-increment||Returns $x, then increments $x by 1.|
|--$x||Pre-decrement||Decrements $x by 1, then returns $x.|
|$x--||Post-decrement||Returns $x, then decrements $x by 1.|
<?php $a = 10; echo 'Value of $a is :'.$a; echo '<br />After Pre-increment value of $a ( i.e. ++$a ) is: '.++$a; $a = 20; echo '<br />Value of $a is :'.$a; echo '<br />After Post-increment value of $a ( i.e. $a++ ) is: '.$a++; $a = 30; echo '<br />Value of $a is :'.$a; echo '<br />After Pre-decrement value of $a ( i.e. --$a ) is: '.--$a; $a = 40; echo '<br />Value of $a is :'.$a; echo '<br />After Post-decrement value of $a ( i.e. $a-- ) is: '.$a--; ?>
Value of $a is :10 After Pre-increment value of $a ( i.e. ++$a ) is: 11 Value of $a is :20 After Post-increment value of $a ( i.e. $a++ ) is: 20 Value of $a is :30 After Pre-decrement value of $a ( i.e. --$a ) is: 29 Value of $a is :40 After Post-decrement value of $a ( i.e. $a-- ) is: 40

Convert HTML + CSS to PDF
Important: Please note that this answer was written in 2009 and it might not be the most cost-effective solution today in 2019. Online alternatives are better today at this than they were back then.
Here are some online services that you can use:
- PDF Layer
- HTML to PDF Rocket
Have a look at PrinceXML.
It's definitely the best HTML/CSS to PDF converter out there, although it's not free (But hey, your programming might not be free either, so if it saves you 10 hours of work, you're home free (since youalso need to take into account that the alternative solutions will require you to setup a dedicated server with the right software).
