PHP Variables

In PHP, variables are used to store data values. A variable starts with the dollar sign ($) followed by the name of the variable. PHP is a loosely typed language, meaning you do not have to declare the data type of a variable.

Example of Variable Declaration

<?php
$variableName = "Hello, World!";
echo $variableName; // Outputs: Hello, World!
?>

Summary of PHP Variables

  • Dynamic Typing: Variables can hold any type of data.
  • Variable Naming: Must start with a letter or underscore, followed by letters, numbers, or underscores.
