How can variables be properly initialized and assigned values in PHP scripts?

Variables in PHP can be properly initialized and assigned values by simply using the variable name followed by the assignment operator (=) and the desired value. It is important to ensure that variables are initialized before being used in the script to avoid errors. It is also good practice to provide meaningful names to variables to improve code readability.

// Initializing and assigning values to variables in PHP
$number = 10;
$string = "Hello, World!";
$boolean = true;

// Using the variables in the script
echo $number; // Output: 10
echo $string; // Output: Hello, World!
echo $boolean; // Output: 1 (true is represented as 1 in PHP)
