You can use a combination of trim to remove leading and trailing whitespace, and preg_replace to replace all newlines and their surrounding spaces internal to the string with a single space:

$str = preg_replace('/\s*\R\s*/', ' ', trim($str));
echo $str;

Note in the above regex \R matches any newline (\r, \n) character.

Output:

PHP: trim - Manual
Because trim() trims characters from the beginning and end of a string, it may be confusing when characters are (or are not) removed from the middle. trim('abc', 'bad') removes both 'a' and 'b' because it trims 'a' thus moving 'b' to the beginning to also be trimmed. So, this is why it "works" whereas trim('abc', 'b') seemingly does not. ltrim() - Strip whitespace (or other characters) from the beginning of a string

Can trim() remove newline characters?
Yes. It removes \n, \r, and other whitespace characters by default.

Does trim() affect UTF-8 or multibyte strings?
It does not break them. But it works at the byte level, not the character level. Use mb_trim() from custom libraries for complex scripts.

The problem is that you're escaping the \n for MySQL first. Try this:

<?php 
   if (isset ($_POST['comment_form_submit'])) {
    $body = $_POST['body'];

    $breaks = array("\r\n", "\n", "\r");
    $newtext = str_replace($breaks, "", $body);

    $newtext = mysql_real_escape_string($newtext);

    echo $newtext;
   }
?>

Read about the escape function you're using to see why: http://php.net/mysql_real_escape_string

Ben's solution is acceptable, but str_replace() could be faster than preg_replace()

$buffer = str_replace(array("\r", "\n"), '', $buffer);

You should be able to replace it with a preg that removes all newlines and carriage returns. The code is:

preg_replace( "/\r|\n/", "", $yourString );

Even though the \n characters are not appearing, if you are getting carriage returns there is an invisible character there. The preg replace should grab and fix those.

July 11, 2024 - This approach transforms the string into a contiguous sequence of characters, useful for processing data where whitespace is irrelevant. Example : PHP code splits the string "Hello World" into an array at spaces using `explode()`, then removes spaces by joining array elements with `implode()`, outputting "HelloWorld".
