Welcome! In this lesson, we're exploring special instructions in PHP: Conditional Statements, along with the break
and continue
statements. As we've learned, loops allow us to execute a block of code numerous times. By combining these loops with conditional statements and incorporating the useful break
and continue
instructions, we achieve more robust and efficient code. Let's dive in!
In PHP, the if
statement triggers actions in our code based on a specific condition. Consider this straightforward example, where the if
statement determines which message to print based on the value of $temperature
:
We can evaluate multiple conditions using elseif
. This phrase means, "If the previous condition isn't true, then check this one":
We use the break
statement whenever we want to exit a loop prematurely once a condition is met:
The continue
statement bypasses the rest of the loop code for the current iteration only:
By utilizing the tools we've covered so far, we can craft more flexible loops. Here's a snippet where we terminate the loop once we find "Charlie":
Congratulations! You are now familiar with PHP's if
statement, as well as the break
and continue
statements and their applications in loops. We encourage you to reinforce your learning through the practice exercises. Try altering the examples to check different conditions or use continue
in different loop scenarios. Happy coding!
