How can PHP developers ensure consistent formatting across multiple lines of output?

To ensure consistent formatting across multiple lines of output in PHP, developers can use the PHP_EOL constant to represent the end of a line. By concatenating PHP_EOL to the end of each line of output, developers can ensure that each line is properly separated and formatted consistently. 

<?php
// Output multiple lines with consistent formatting
echo "Line 1" . PHP_EOL;
echo "Line 2" . PHP_EOL;
echo "Line 3" . PHP_EOL;
?>
