What is the correct way to end a PHP statement?

How to Correctly End a PHP Statement

The correct way to end a PHP statement is with a semicolon (;). PHP is highly reliant on correct syntax, just like any other programming language, and forgetting to end a PHP statement with a semicolon can result in errors and unexpected behavior.

A statement in PHP is a command that exists for the PHP interpreter to execute. In PHP syntax, each individual statement is separated by a semicolon. It functions as a separator, differentiating one statement from the next.

Let's take a look at an example:

<?php
$hello = "Hello, world!";
echo $hello;
?>

In this example, there are two PHP statements. The first one is $hello = "Hello, world!"; where we're assigning the string "Hello, world!" to the variable $hello. The second statement, echo $hello;, is then printing the value of $hello to the screen. As you can see, both of these statements are ended with a semicolon.

Keep in mind that the end tag of a block of PHP code automatically implies a semicolon; there's no need to have a semicolon terminating the last line of a PHP block.

<?php
$hello = "Hello, world!";
echo $hello
?>

In the above code, even though there is no semicolon after the echo statement, it is still correct because the end of the PHP code block (?>) automatically implies a semicolon.

Remember, consistently using semicolons to end your PHP statements is a best practice that can prevent errors. It creates readable code and makes it easier for others (and future you) to understand the code's flow.
