Php Tutorial Part 3

Variables Continue:
You can have very useful functions with variables.
For example:

$var1 = "Welcome";

$var2 = " to my website";

echo $var1 . $var2;

?>

The above code will output in one line Welcome to my website (They words are not connected why? Because in the $var2 the beginning starts with space if it was not a space character there the programmer should do this echo $var1 . " " . $var2; This will print an extra space between the two characters.
While i was designing a php website someone ask how do i find out what is the length of a variable in phpThe answer is simple and is provided for you in php with the function strlen() The use is:

$var1 = "Welcome to Cyprus have a Nice day";

//call a function to show how many characters are in a varialbe

echo strlen($var1);

//The output should be: 33

?>

In php they are many functions that will help you with your string variables we will refer to them later in the tutorials
