What potential issues can arise when removing line breaks from code in PHP?

When removing line breaks from code in PHP, potential issues can arise if the code relies on specific line breaks for readability or functionality. To avoid these issues, you can use the PHP `preg_replace` function with a regular expression pattern to remove line breaks while preserving any necessary formatting. 

<?php
$code = "Some code with line breaks;\nand more code on the next line;";
$code = preg_replace("/\r|\n/", "", $code);
echo $code;
?>
