Use A Conditional To Check Less Than Number In PHP

PHP, a popular server-side scripting language, is typically used to generate dynamic web content. An essential tool in PHP, and indeed in any programming language, is the ability to use conditionals to manage the flow of an application based on certain conditions. This article will focus on how to use a conditional to check if a number is less than another number in PHP.

Code Snippet ‘Check Less Than Number’

<?php
    $num1 = 4;
    $num2 = 7;

    if($num1 < $num2) {
        echo "$num1 is less than $num2.";
    } else {
        echo "$num1 is not less than $num2.";
    }
?>

Code Explanation for ‘Check Less Than Number’

In the above code snippet, we are using the less-than operator to compare two numbers and then output a message based on the result of the comparison.

Taking it step by step, we begin by declaring two variables, $num1 and $num2, and assigning them values - in this case, 4 and 7 respectively.

Next, we have an if statement, which is the core of our conditional code. The condition we are testing is $num1 < $num2. In other words, we are asking, “Is $num1 less than $num2?”

In PHP, the less than operator < checks if the value on its left side is less than the value on its right side. If the condition is true (i.e., $num1 is less than $num2), PHP will execute the code block within the if statement. In this case, it will echo the string “$num1 is less than $num2.”

If the condition is false (i.e., $num1 is not less than $num2), PHP will execute the code block within the else statement. In this case, it will echo the string “$num1 is not less than $num2.”

It’s as simple as that! By manipulating the values of $num1 and $num2, you can test different outcomes with the less than operator. This logic can be used to control the flow of your PHP application based on the relative values of any two numbers.
