PHP Function to Convert LineBreaks to NewLines
June 15th, 2007 – Comments Off on PHP Function to Convert LineBreaks to NewLines
While PHP has a very nice little function (nl2br) to convert newlines (\n) to line breaks (<br>), moving in the opposite direction is not quite so easy. This function should hopefully help to allow you to convert line breaks to new lines.
<?php /* This function will convert line breaks or other tags passed in the $tags variable to linebreaks. Multiple $tags must be separated by spaces, and must consist of the regular tag text. Ie. $result = br2nl($text_to_filter, "br p blockquote") */ function br2nl($text, $tags = "br") { $tags = explode(" ", $tags); foreach($tags as $tag) { $text = eregi_replace("<" . $tag . "[^>]*>", "\n", $text); $text = eregi_replace("</" . $tag . "[^>]*>", "\n", $text); } return($text); } // Usage: $text_to_filter = "<p>This is my <br>sample<br>text. The default code listed here " . "should replace the br's with new lines.</p><p>The second example is more advanced, " . "stripping out both the BR's as well as the P tags.</p>"; // Example of replacing BR tags (default) $result = br2nl($text_to_filter); echo "<pre>$result</pre>"; // Example of replacing both BR and P tags $result = br2nl($text_to_filter, "br p"); echo "<pre>$result</pre>"; ?>Filed in: Code Snippets
