Logical operators: They are used to combine multiple conditions and evaluate them. They
return a Boolean value 'True' or 'False' as output. Logical operators of PHP are AND(&&), OR (||),
XOR(^), NOT(!). Let us create a PHP script to use some of the logical operators.
<HTML>
<HEAD> <TITLE> Using Variables </TITLE> </HEAD>
<BODY>
<?php
$a = true;
$b = false;
echo var_dump($a and $b);
echo "<br>",var_dump($a or $b);
echo "<br>",var_dump($a xor $b);
?>
</BODY>
</HTML>

output when executing the preceding script:
