What could be causing a line break when entering a space in a textarea pre-filled with text using PHP?

When entering a space in a textarea pre-filled with text using PHP, the line break may be caused by the presence of newline characters (\n) in the pre-filled text. To solve this issue, you can use the PHP function `trim()` to remove any leading or trailing whitespace, including newline characters, from the pre-filled text before displaying it in the textarea. 

<?php
// Pre-filled text with newline characters
$prefilled_text = "This is a pre-filled text\nwith a newline character";

// Remove leading and trailing whitespace, including newline characters
$clean_text = trim($prefilled_text);

// Display the cleaned text in a textarea
echo '<textarea>'.$clean_text.'</textarea>';
?>
