Comparison Operators in PHP : Tutorial

We can compare values of two operants (variables) using Comparison operators.

Comparison Opearators List

 ==   :  Equal to
 ===  :  Identical
 <>   :  Not equal
 !=   :  Not equal
 !==  :  Not identical
 <    :  Less than
 <=   :  Less than equal to
 >    :  Greater than
 >=   :  Greater than or equal to 

Syntax :

boolean operant1 OPERATOR operant2

Example : Equal to Operator

<?php



$a = 5;
$b = 5;


echo var_dump($a == $b);

}

?>

Output


bool(true)

Example : Identical

<?php



$a = 5;
$b = 2;


echo var_dump($a === $b);

}

?>

Output


bool(false)

Example : No Equal to

<?php



$a = 5;
$b = 2;


echo var_dump($a != $b);

echo var_dump($a <> $b);

}

?>

Output


bool(true)
bool(true)

Example : No Identical

<?php


$a = 5;
$b = 2;


echo var_dump($a !== $b);

}

?>

Output


bool(true)

Example : Less than

<?php


$a = 5;
$b = 2;


echo var_dump($a < $b);

}

?>

Output


bool(false)

Example : Less than equal to

<?php


$a = 2;
$b = 5;


echo var_dump($a <= $b);

}

?>

Output


bool(true)

Example : Greater than

<?php


$a = 2;
$b = 5;


echo var_dump($a > $b);

}

?>

Output


bool(false)

Example : Greater than equal to

<?php


$a = 2;
$b = 5;


echo var_dump($a >= $b);

}

?>

Output


bool(false)
