PHP Regular Expression

I have a string having data in html format. This data is actually will be emails . I have a class for converting html to text. Before converting this in text, I need to eliminate few things for which I need regular expression. Am using PHP.

I need to eliminate following things
1:All new lines should replaced with (dot/full stop) . sign
2: Fwd and replied emails have Date , from a, subject and To fields. If need such complete block to be eliminated from string.
3: All formats like "--- On Sat, 6/27/09, aqeel chishti <chishtiaaa@hotmail.com> wrote:" and "Date: Saturday, June 27, 2009, 10:05 PM" should be eliminted .
4: Foter advertisements should be eliminated.

All these four points may be repeating several time in one string . So all should be eliminated. Below is an example of data in string .

Check this one:

$toBeDeleted = array(
	"~^(Date|From|Subject|To|Other-Headers|More-Headers):.*$~",
	"^.*Microsoft brings you a new way to.*$",
	"^.*Yahoo is your friend.*$",
	"^.*partial snippet of other footer texts here.*$",
	"^.*more partial snippet of other footer texts here.*$",
);
 
//stuff you want to delete goes in the above array
$messages = preg_replace($toBeDeleted,'',$messages);
 
//replace one or more newlines of either mac, windows or unix with a '.'
//if you don't want it to replace more than two returns with one dot, get rid of the + in the expression below
//do this last because the above expression will generate lots of empty lines
$messages = preg_replace("~[\r\n]+~",'.',$messages);

I use this code and getting this eror.

Warning: preg_replace() [function.preg-replace]: No ending delimiter '^' found in C:\xampp\htdocs\imap\test.php on line 133.

      $toBeDeleted = array(
                  "~^(Date|From|Subject|To|Other-Headers|More-Headers):.*$~",
                  "^.*Microsoft brings you a new way to.*$",

                  "^.*more partial snippet of other footer texts here.*$",
      );
$msgBody = preg_replace($toBeDeleted,'',$msgBody);
$msgBody = preg_replace("~[\r\n]+~",'.',$msgBody);

Sorry, left out the delimiters in the array above, here's a corrected snippet below.

$toBeDeleted = array(
        "~^(Date|From|Subject|To|Other-Headers|More-Headers):.*$~",
        "~^.*Microsoft brings you a new way to.*$~",
        "~^.*Yahoo is your friend.*$~",
        "~^.*partial snippet of other footer texts here.*$~",
        "~^.*more partial snippet of other footer texts here.*$~",
);
 
//stuff you want to delete goes in the above array
$messages = preg_replace($toBeDeleted,'',$messages);
 
//replace one or more newlines of either mac, windows or unix with a '.'
//if you don't want it to replace more than two returns with one dot, get rid of the + in the expression below
//do this last because the above expression will generate lots of empty lines
$messages = preg_replace("~[\r\n]+~",'.',$messages);

Strange& no reason for it not to. Will reexamine.

Played around with it because it's a script I will use. Don't have the time to finish this now, but if you finish it, please post your findings:

$toBeDeleted = array(
        "~[\n\r]*[\s>*](Date|From|Subject|To|Cc|Bcc|More-Headers):[^\r\n]+($|[\r\n])~i",
        "~^--+.+$~",
        "~^.*Microsoft brings you a new way to.*$~",
        "~^.*Yahoo is your friend.*$~",
        "~^.*partial snippet of other footer texts here.*$~",
        "~^.*more partial snippet of other footer texts here.*$~",
);
$msgBody = preg_replace("~[\r]+~","\n\n\n\n",$msgBody);
$msgBody = preg_replace($toBeDeleted,'!!!"""!!!',$msgBody);
//$msgBody = preg_replace("~[\r\n]+~",'.',$msgBody);
$msgBody = preg_replace("~[\r\n]+[\s^\r\n]+[\r\n]+~","\r",$msgBody);
$msgBody = preg_replace("~[\r\n]+[\s^\r\n]+[\r\n]+~",'.',$msgBody);
echo "<pre>{$msgBody}</pre>";
