Convert BR to Newline

Technique #1

function br2newline( $input ) {
     $out = str_replace( "<br>", "\n", $input );
     $out = str_replace( "<br/>", "\n", $out );
     $out = str_replace( "<br />", "\n", $out );
     $out = str_replace( "<BR>", "\n", $out );
     $out = str_replace( "<BR/>", "\n", $out );
     $out = str_replace( "<BR />", "\n", $out );
     return $out;
}

Converts a break tag to a newline - no matter what kind of HTML is being processed.

Technique #2

function br2nl( $input ) {
 return preg_replace('/<br(\s+)?\/?>/i', "\n", $input);
}

    Technique #2 will work a lot better than #1
    But in #1, you could just use the first three calls and use str_ireplace() instead.

    I’m suffered a lot. A used ” but I should use ‘. Could it be really a mistake?

    please help me out why is “i” used in
    function br2nl( $input ) {
    return preg_replace(‘//i’, “\n”, $input);
    }

    at the end of first parameter of preg_ replace

    You can also do:


    function _br2nl($input)
    {
    return str_replace(array("", "", "", "", "", ""),"\n", $input );
    }

      <pre><code>
      function _br2nl($input)
      {
      return str_replace(array(“<br>”, “<BR>”, “<br/>”, “<BR/>”, “<br />”, “<BR />”),”\n”, $input );
      }
      </code></pre>

    `(\s+)?` could just be `\s*`.
