First thing I would suggest is to use a different character for your forward slashes as sed dividers. If you are using filenames and they contain /'s....you can use = or others ....i.e

Script:
text="/opt/string/text"
echo $text
text=`echo $text | sed 's=/=\\\/=g'`
echo $text

Notice the 'g' on the end (globally do this). Without 'g' you're looking at the first instance of this for each line.

You need 3 backslashes in the 'to' part of the sed command. As you know the \ means take next char literally...so it's basically \\ for the backslash...the \/ for the forward slash.

imap_mime_header_decode - Decode MIME header elements

SYNOPSIS
array imap_mime_header_decode (string $text) DESCRIPTION
Decodes MIME message header extensions that are non ASCII text (see RFC2047). PARAMETERS
o $text - The MIME text RETURN VALUES
The decoded elements are returned in an array of objects, where each object has two properties, charset and text. If the element hasn't been encoded, and in other words is in plain US-ASCII, the charset property of that element is set to default. EXAMPLES
Example #1 imap_mime_header_decode(3) example <?php $text = "=?ISO-8859-1?Q?Keld_J=F8rn_Simonsen?= <keld@example.com>"; $elements = imap_mime_header_decode($text); for ($i=0; $i<count($elements); $i++) { echo "Charset: {$elements[$i]->charset} "; echo "Text: {$elements[$i]->text} "; } ?> The above example will output: Charset: ISO-8859-1 Text: Keld Jorn Simonsen Charset: default Text: <keld@example.com> In the above example we would have two elements, whereas the first element had previously been encoded with ISO-8859-1, and the second element would be plain US-ASCII.
