PHP Comparison Operators - Comparison Operators in PHP

PHP Comparison Operators

• PHP comparison operators are used to compare two values (number or string).
• These operators are used in conditional statements (like if/else) to compare values and return a boolean value (true or false).

Operator	Syntax	Operation
Equal To (==)	$a == $b	Returns True if both the operands are equal
Not Equal To (!=)	$a != $b	Returns True if both the operands are not equal
Not Equal To (<>)	$a <> $b	Returns True if both the operands are unequal
Identical (===)	$a === $b	Returns True if both the operands are equal and are of the same type
Not Identical (!==)	$a == $b	Returns True if both the operands are unequal and are of different types
Less Than (<)	$a < $b	Returns True if $a is less than $b
Greater Than (>)	$a > $b	Returns True if $a is greater than $b
Less Than or Equal To (<=)	$a <= $b	Returns True if $a is less than or equal to $b
Greater Than or Equal To (>=)	$a >= $b	Returns True if $a is greater than or equal to $b

Sample Code

<?php
$a = 80;
$b = 50;
$c = "80";
var_dump($a == $c);
echo "<br>";
var_dump($a != $b);
echo "<br>";
var_dump($a <> $b);
echo "<br>";
var_dump($a === $c);
echo "<br>";
var_dump($a !== $c);
echo "<br>";
var_dump($a < $b);
echo "<br>";
var_dump($a > $b);
echo "<br>";
var_dump($a <= $b);
echo "<br>";
var_dump($a >= $b);
?>
