Logical operators in PHP are used to combine multiple conditions and return a single boolean result. They are essential in decision making, conditional statements, and controlling program flow in web development.<\/p>\n\n\n\n
These operators help developers check whether multiple conditions are true or false at the same time.<\/p>\n\n\n\n
Logical operators are used to perform logical operations on expressions that return true or false. They are mostly used with if, else, and loop structures.<\/p>\n\n\n\n
The AND operator returns true only if all conditions are true.<\/p>\n\n\n\n
Example<\/p>\n\n\n\n
<?php
$age = 20;
$hasID = true;
if ($age >= 18 && $hasID == true) {
echo \"Allowed to enter\";
}
?><\/code><\/pre>\n\n\n\nOR Operator<\/h3>\n\n\n\n
The OR operator returns true if at least one condition is true.<\/p>\n\n\n\n
Example<\/p>\n\n\n\n
<?php
$marks = 40;
$attendance = 85;
if ($marks >= 50 || $attendance >= 80) {
echo \"Pass\";
}
?><\/code><\/pre>\n\n\n\nNOT Operator<\/h3>\n\n\n\n
The NOT operator reverses the result of a condition.<\/p>\n\n\n\n
Example<\/p>\n\n\n\n
<?php
$isLoggedIn = false;
if (!$isLoggedIn) {
echo \"Please login first\";
}
?><\/code><\/pre>\n\n\n\nXOR Operator<\/h3>\n\n\n\n
The XOR operator returns true if only one condition is true, but not both.<\/p>\n\n\n\n
Example<\/p>\n\n\n\n
<?php
$a = true;
$b = false;
if ($a xor $b) {
echo \"Only one condition is true\";
}
?><\/code><\/pre>\n\n\n\nHow Logical Operators Work in PHP<\/h2>\n\n\n\n
Logical operators evaluate expressions from left to right and return a boolean result. They are commonly used to control access, validate forms, and apply business rules in web applications.<\/p>\n\n\n\n
