What is the difference between <?= and echo in PHP?

The main difference between <?= and echo in PHP is that <?= is a shorthand syntax for echoing output, while echo is a language construct. Both <?= and echo can be used to output data to the browser, but <?= is typically used for shorter, simpler statements, while echo is more versatile and can handle more complex output scenarios.

// Using <?= shorthand syntax
<?= "Hello, World!"; 

// Using echo language construct
echo "Hello, World!";
