my_string="Welcome to MySite.com"
Response.Write ( my_string )
Response.Write "Length of this string = " & len(my_string)
Response.Write "Number of bytes Required for this string = " & lenB(my_string)

The output of this will also show the number of bytes required. Here in this case it will print this:

Welcome to MySite.com

Length of this string = 21

Number of bytes Required for this string = 42

Arithmetic Operators:

+ Addition Add two values

- Subtraction Subtract the second value from the first

* Multiplication Multiply two values

/ Division Divide the first value by the second

% Modulus Divide the first value by the second and return only the remainder
(for example, 7 % 5 yields 2)

Comparison Operators:

= = Equal Checks for equal values

= = = Identical Checks for equal values and data types

! = Not Equal Checks for values not equal

! = = Not Identical Checks for values not equal or not the same data type

< Less than Checks for one value being less than the second

> Greater than Checks for one value being greater than the second

< = Less than or Equal to Checks for on value being less than or equal to the second

> = Greater than or Equal to Checks for on value being greater than or equal to the second

Logical Operators:

And Checks if two or more statements are true

&& Same as And

Or Checks if at least one of two statements is true

|| Same as Or

Xor Checks if only one of two statements is true

! Checks if a statement is not true

Increment and Decrement Operators:

++value Pre-Increment Adds 1 to the value before processing the expression which uses the value

–value Pre-Decrement Subtracts 1 from the value before processing the expression which uses the value

value++ Post-Increment Adds 1 to the value after processing the expression which uses the value

value– Post-Decrement Subtracts 1 from the value after processing the expression which uses the value

SELECT left(item_num, 4) FROM flowers;

If item_num = 754861 then the output will be: 7548

SELECT right(item_num, 4) FROM flowers;

If item_num = 754861 then the output will be: 4861

Code:

<?php

$s = “Coding PHP is fun.”;

print “ereg_replace(): ” .
ereg_replace(“CODING”, “Learning”, $s) . “<br>”;
print “eregi_replace(): ” .
eregi_replace(“CODING”, “Learning”, $s);

?>

Output:

ereg_replace(): Coding PHP is fun.
eregi_replace(): Learning PHP is fun.
Explanation:

eregi_replace() is case insensitive, while ereg_replace() is not.

$formatted = number_format($number,2);
