Operators	Description
<	Less than
>	Greater than
<=	Less than or Equal to
>=	Gretaer than or Equal to
==	Equal to
===	Equal to
!=	Not Equal to
!==	Not Equal to

Example for <(Less than)

Source Code :

12345678<?php
$a = 10;  
$b = 6;
if($a < $b)
 echo "a is less than b";
else
 echo "a is not less than b";
?>

Output :

a is not less than b

Example for >(Greater than)

Source Code :

12345678<?php
$a = 10;  
$b = 6;
if($a > $b)
 echo "a is greater than b";
else
 echo "a is not greater than b";
?>

Output :

a is greater than b

Example for <=(Less than or Equal to)

Source Code :

12345678<?php
$a = 10;  
$b = 10;
if($a <= $b)
 echo "a is less than or equal to b";
else
 echo "a is not less than or equal to b";
?>

Output :

a is less than or equal to b

Example for >=(Greater than or Equal to)

Source Code :

12345678<?php
$a = 10;  
$b = 5;
if($a >= $b)
 echo "a is greater than or equal to b";
else
 echo "a is not greater than or equal to b";
?>

Output :

a is greater than or equal to b

Difference between == and ===

Program में दो variables दिए हुए है उन दोनों का data type अलग-अलग है | उसमे से $a की value; integer है और $b की value double है |

== ये operator अपनी values को compare करता है |

=== ये operator अपनी values और उसके data types को compare करता है |

Source Code :

123456789101112131415<?php
$a = 5;     //Integer
$b = 5.0;   //Double

if($a == $b)
 echo "a is equal to b <br />";
else
 echo "a is not equal to b <br />";


if($a === $b)
 echo "a is equal to b <br />";
else
 echo "a is not equal to b <br />";
?>

Output :

a is equal to b 
a is not equal to b 

Difference between != and !==

Program पर दो variables है लेकिन उन दो variables की values same है पर data types अलग-अलग है |

!= ये operator अपनी values को compare करता है |

!== ये operator अपनी values और उसके data types को compare करता है |

Source Code :

123456789101112131415<?php
$a = 5;     //Integer
$b = "5";   //String

if($a != $b)
 echo "a is not equal to b <br />";
else
 echo "a is equal to b <br />";


if($a !== $b)
 echo "a is not equal to b <br />";
else
 echo "a is equal to b <br />";
?>

Output :

a is equal to b 
a is not equal to b
