How does the assignment operator "=" function in PHP when used in conjunction with echo?

When the assignment operator "=" is used in conjunction with echo in PHP, it simply assigns the value on the right-hand side to the variable on the left-hand side. This means that the variable is assigned the value and then the echoed output is displayed. If you want to display the value of the variable without assigning it, you can simply echo the variable directly without using the assignment operator. 

// Assigning a value to a variable and then echoing it
$value = "Hello World";
echo $value;

// Echoing a value without assigning it to a variable
echo "Hello World";
