Use A Conditional To Check Greater Than Number In PHP

In this article, we are going to explore how to use conditionals to check numbers that are greater than a certain value in PHP. Learning this will enhance your skill in handling and manipulating data in PHP.

Code snippet for Checking Greater Number in PHP

<?php
   $a = 10;
   $b = 20;
   
   if ($b > $a) {
       echo "B is greater than A.";
    } else {
       echo "A is equal or greater than B.";
    }
?>

Code Explanation for Checking Greater Number in PHP

In PHP, we use conditional statements to perform different actions for different conditions. We specifically use “if” conditional expressions to determine whether or not a section of code should be executed. The structure of “if” statements is generally: if(condition) { code to be executed if the condition is TRUE }.

Now, let’s get into the code snippet above.

We begin with the ”<?php” tag to enter into PHP mode. Then we define two variables $a and $b with values 10 and 20 respectively.

Next, we have an “if” statement that checks if $b is greater than $a. If true, then the script will print “B is greater than A.” on the web page.

The “else” clause here is executed if the condition given in the “if” clause is not true - in this case, if $b is not greater than $a. Hence the script will print “A is equal or greater than B.” on the web page.

In conclusion, using “if” conditional expressions, we may check if one number is greater than another. The code snippet and explanation provided in this article should guide you on how to use this essential PHP command. Remember, practice makes perfect, so do well to practice regularly.
