PHP variable

Variable is what the program used to store any values in computer’s memory such as text, number, date/time, etc.

Declaring and accessing variable

Before a variable is used, you must declare it. To declare a variable in PHP, you can use the following syntax:

To assign a value to the variable, write:


$yourname="Yuk Sovandara";
Note: The name of variable must start with a letter or underscore not a number.
To use the value of the variable, you need only specify $ and variable name.
$var="I like PHP very much.";
echo $var; // the value of var is used(display on the screen)
Note: It is no need to specify data type when you declare a variable in PHP.
