Struggling with backslashes ( 5 Views )

1. Hi all.
   
   My problem is the following:
   
   I have a little script that saves the content of a textarea on my site to a simple txt file. Discussion on that script can be found here: http://www.sitepoint.com/forums/showthread.php?t=162729
   
   When I enter a ' or " in the text which is saved to the txt file, it automatically saves a backslash in front of it. If it would do that once, I would not mind. But every time the script is ran, another backslash is added.
   
   Is there a way to go around this? I know the backslash is put there so that the PHP script is run properly without using the ' or " in the code. Just do not want it there...
   
   Thanks

2. $text = str_replace("\\","",$text);
   
   Maybe this will help...? (you need the two slashes, otherwise php will "think" the first part of str_replace hasn't been closed... (or something like that)

3. I get an error now:
   
   Notice: Undefined variable: text in write.php on line 16
   
   write.php :
   

   PHP Code:

   ---

   if (isset($_POST['text'])) {
   $f = fopen('bestel-kantoor.txt', 'w');
   fwrite($f, $_POST['text']);
   $text = str_replace("\\","",$text);
   fclose($f);
}

4. PHP Code:

   ---

   if (isset($_POST['text'])) {
   $text = str_replace("\\","",$_POST['text']);
   $f = fopen('bestel-kantoor.txt', 'w');
   fwrite($f, $text);
   fclose($f);
}

6. If magic_quotes_gpc is set, PHP automatically escapes quotes, backslashes and so on. Try this:

   PHP Code:

   ---

   $text = get_magic_quotes_gpc() ? $_POST['text'] : addslashes($_POST['text']);

   Edit: A little late ... :)

7. Here is a little function that is either just like, or somewhat like a function in Mojavi (php framework):
   
   

   PHP Code:

   ---

   function myStripSlashes (& $params) {
    $keys  = array_keys($params);
    $count = sizeof($keys);
    for ($i = 0; $i < $count; $i++) {
        $value =& $params[$keys[$i]];
        if (is_array($value)) {
            myStripSlashes($value);
        } else {
            $value = stripslashes($value);
        }
    }
}


   ---

   And to use it:
   
   

   PHP Code:

   ---

   if (ini_get('magic_quotes_gpc') == 1 ) {
    if( sizeof($_GET) > 0 )
        myStripSlashes($_GET);
    if( sizeof($_POST) > 0 )
        myStripSlashes($_POST);
    if( sizeof($_COOKIE) > 0 )
        myStripSlashes($_COOKIE);
}


   ---

   If you just use that before all of your scripts, things should be OK.
