PHP Variables

-
  In PHP, a variable starts with the  $  sign, followed by the name of the variable: for example: <?php $txt =  "Hello RK!" ; $x =  5 ; $y =  10.5 ; ?> A variable can have a short name (like x and y) or a more descriptive name (age, carname, total_volume). Rules for PHP variables: A variable starts with the  $  sign, followed by the name of the variable A variable name must start with a letter or the underscore character A variable name cannot start with a number A variable name can only contain alpha-numeric characters and underscores (A-z, 0-9, and _ ) Variable names are case-sensitive ( $age  and  $AGE  are two different variables) NOTE: Remember that PHP variable names are case-sensitive! Output The PHP  echo  statement is often used to output data to the screen. The following example will show how to output text and a variable: Example 1: <?php $txt =  "RK" ; echo   "I love $txt!" ; ?> Example 2: <?php $txt =  "RK" ; echo   &q

 There are following types of operator in PHP: Arithmetic operators Assignment operators Comparison operators Increment/Decrement operators Logical operators String operators Array operators Conditional assignment operators Arithmetic operators: + Addition $x + $y Sum of $x and $y - Subtraction $x - $y Difference of $x and $y * Multiplication $x * $y Product of $x and $y / Division $x / $y Quotient of $x and $y % Modulus $x % $y Remainder of $x divided by $y ** Exponentiation $x ** $y Result of raising $x to the $y'th power Assignment operators: x = y x = y The left operand gets set to the value of the expression on the right x += y x = x + y Addition x -= y x = x - y Subtraction x *= y x = x * y Multiplication x /= y x = x / y Division x %= y x = x % y Modulus Comparison operators: == Equal $x == $y Returns true if $x is equal to $y === Identical $x === $y Returns true if $x is equal to
