How can using <?= instead of <?php echo affect code readability and safety in PHP?

Using <?= instead of <?php echo can affect code readability because it is a shorthand way of writing the same thing. However, using <?= can make the code more concise and easier to read. In terms of safety, there is no direct impact on security by using <?= instead of <?php echo.

// Using &lt;?= instead of &lt;?php echo for improved code readability
&lt;?= $variable ?&gt;
