Delete a big string of text

[Skinzy]

Hi,

 

Basically I have a big peice of text in my php script (i'm parsing email, i've got rid of the MIME stuff) and now i'm trying to remove a fixed signiture that's not going to change.

 

The str_replace fails because (i think) the string is too long, if i take a small section of the string and for example change $goaway to "The contents of this email are" it works and removes that bit of text from the variable. But when I do the whole lot it doesn't do anything. Is there another method like str_replace to get rid of a big chunk of text?

 

<?php

require_once('MimeMailParser.class.php');

$path = 'email.eml';
$Parser = new MimeMailParser();
$Parser->setPath($path);

$to = $Parser->getHeader('to');
$from = $Parser->getHeader('from');
$subject = $Parser->getHeader('subject');
$text = $Parser->getMessageBody('text');
$html = $Parser->getMessageBody('html');
$attachments = $Parser->getAttachments();

$save_dir = '/home/freelance/domains/freelance.skinzy.net/public_html/uploads/';
foreach($attachments as $attachment) {

  $filename = $attachment->filename;

  if ($fp = fopen($save_dir.$filename, 'w')) {
    while($bytes = $attachment->read()) {
      fwrite($fp, $bytes);
    }
    fclose($fp);
  }
}

$goaway = "=20 =20 -------------------------------------------------------------------------= ------- The contents of this email are confidential and are only intended for = the stated recipient. The email is the property of Direct Enquiries = Limited and if you are not the stated recipient you must not deal with = it in any way other than to notify us of its receipt by you in error. = This email is not intended nor should it be taken to create any legal = relations, contractual or otherwise.

$clear = " ";

$please = str_replace($goaway, $clear, $text);

echo "Subject: " . $subject . "<br /> Text:" . $please;

?>

 

really appreciate it.

Hrmn, I wasn't aware that str_replace had any limits on it.

 

There is another PHP function you can use.  preg_replace()...and I know for a fact it has no limit

It might not have a limit on it, but somthing is stopping it working.

 

Can I use preg_replace the same way as str_replace?

Are you sure that there are no new line/carriage returns in the text you're trying to replace?  If you're omitting line breaks or trailing spaces, it will won't match the text and won't replace it.

 

You don't need a variable for your replace, either.  You can simply use something like:

str_replace($goaway, null, $text)

or

str_replace($goaway, '', $text)

After a bit of googling i've now sorted it with:

 

$pos = strpos($text, "-------------------------------------------------------------------------=");
$please = substr($text, 0, $pos);
$text2 = str_replace($up, "<br /> <br />", $please);

 

thanks for your help
