[SOLVED] Function that UNformats text

[fri3ndly]

Hi all!

 

I recently found and am using the following fuction that will format  entered text into paragraphs:

 

function formatString($string)
{
      $x_string = explode("\r\n\r\n",trim($string)); // explode on double carriage returns
      $x_count = count($x_string);
      $string = '';
      for($i=0; $i<$x_count; $i++){
      	$string .= '<p>'.$x_string[$i].'</p>';
      }
    return str_replace('<p></p>','',$string); // removes empty paragraphs
}

 

Is is possible to make a function that will reverse this (for the sake of editing through a CMS)? If so can someone give me some guidelines?

Lol, I just added a strip tags function!

First, you should always store the original string and only use functions like this when writing to the screen. Then, you wouldn't need to reverse it.

 

Next, you can shorten your function by using the implode() function:

<?php
function formatString($string)
{
      $x_string = explode("\r\n\r\n",trim($string)); // explode on double carriage returns
      $string = str_replace('<p></p>','','<p>' . implode('</p><p>',$x_string) . '</p>');
      return $string;
}?>

 

You also may just be able to use the nl2br() function:

<?php
function formatString($string) {
   return(nl2br($string));
}
?>

 

Using the strip_tags() function, does not give you the original string back. Your new string will not have the "\r\n" characters in it.
