Assignment operators in PHP

There are two types of assignment operators for PHP, namely:

(1) "=": assigns the value of the right expression to the left operand. It copies the value of the right expression to the left-hand operand. In other words, the left operand is first requested for a piece of memory, and then the copied value is placed in this memory.

(2) "&": Reference assignment means that both variables point to the same data. It will allow two variables to share a piece of memory, and if the memory stored data changes, then the values of the two variables will change.

<?php

$a = "I am learning php! in mu-class net ";

$b = $a;

$a = "I am learning php! every day in Mu-class net ";

$c =& $a;

echo $b. " <br/> ";

echo $c. " <br/> ";

?>

I am learning php! in MU-class network. I study php! every day in the school network
