reading email attachments

[andrewpasetti]

I have a mailbot script that reads in an email from a .forward file and process the message according to some business rules. I am trying to process attachments with this script, but when I save the file after the read, the file gets corrupted.

When I open the file, it appears that all the information was transferred correctly. It's missing something that I just can't find.

Perhaps someone has done this already and can suggest what I am doing wrong.

Thanks,

Andrew Pasetti

----mailbot script---
#!/usr/local/php/bin/php
<?
// Grab the entire message first.
$stdin=fopen("php://stdin","r");

while (!feof($stdin))
$message.=fread($stdin,1024);
fclose($stdin);

// Make sure EOLs are \r\n
$message=str_replace("\n","\r\n",$message);

// grab the boundary marker
if (ereg('boundary=\"=_[a-zA-Z0-9].[a-zA-Z0-9]\"',$message,$regs))
{
list(,$boundary) = explode("=",$regs[0],2);
$boundary = str_replace('"',"",$boundary);

// grab the attachment headers based on the boundary
$headers = explode("--".$boundary,$message);

// loop through each header, except for the first one
// which is just normal email headers.
for ($i=1;$i<count($headers);$i++)

{
$headerList=explode("\r\n",str_replace("\r\n\t"," ",$headers[$i]));
list(,$contentDisposition) = explode(":",$headerList[3]);

    // if the header is an attachment, attempt to store it as a file.
    if (ereg("attachment",$contentDisposition))
    {
        list(,$fileName) = explode("=",$contentDisposition);
        $fileName = str_replace("\"","",$fileName);

        $attachment = "";
        for ($j=4;$j<count($headerList);$j++)
        {
            $attachment .=  $headerList[$j];
        }

        $fp = fopen("../../transactions/andy/$fileName","w+");
        fwrite($fp,$attachment);
        fclose($fp);
    }
}
