PHP Comparison Operators (Examples)



Hello dear readers! welcome back to another section of my tutorial on PHP. In this tutorial guide, we will be discussing about the PHP Comparison Operators.

Try the following example below to have a proper understanding of all comparison operators. Copy and paste the following PHP codes in a text.php file and save the file in your PHP Server's document root and then browse it using any Web browser.

<html>
   
   <head>
      <title>Comparison Operators</title>
   </head>
   
   <body>
      
      <?php
         $a = 42;
         $b = 20;
      
         if( $a == $b ) {
            echo "TEST1 : a is equal to b<br/>";
         }else {
            echo "TEST1 : a is not equal to b<br/>";
         }
      
         if( $a > $b ) {
            echo "TEST2 : a is greater than  b<br/>";
         }else {
            echo "TEST2 : a is not greater than b<br/>";
         }
      
         if( $a < $b ) {
            echo "TEST3 : a is less than  b<br/>";
         }else {
            echo "TEST3 : a is not less than b<br/>";
         }
      
         if( $a != $b ) {
            echo "TEST4 : a is not equal to b<br/>";
         }else {
            echo "TEST4 : a is equal to b<br/>";
         }
      
         if( $a >= $b ) {
            echo "TEST5 : a is either greater than or equal to b<br/>";
         }else {
            echo "TEST5 : a is neither greater than nor equal to b<br/>";
         }
      
         if( $a <= $b ) {
            echo "TEST6 : a is either less than or equal to b<br/>";
         }else {
            echo "TEST6 : a is neither less than nor equal to b<br/>";
         }
      ?>
      
   </body>
</html>

Output

When the above code is executed, it will produce the following result -

TEST1 : a is not equal to b
TEST2 : a is greater than b
TEST3 : a is not less than b
TEST4 : a is not equal to b
TEST5 : a is either greater than or equal to b
TEST6 : a is neither less than nor equal to b
