passing paremeters from PHP Email piping

问题

I have a PHP Script that received information from a piped email forwarder.

Currently everything works perfectly. I just want to manipulate the received parameters to receive only the data I want from the email

the script is:

#!/usr/local/bin/php -q

<?PHP
//get email
$fd = fopen("php://stdin", "r");
$email_content = "";
while (!feof($fd)) {
$email_content .= fread($fd, 1024);
}
fclose($fd); 
//get email end


//get variables from email start


//split the string into array of strings, each of the string represents a single line, recieved
$lines = explode("\n", $email_content);

// initialize variable which will assigned later on
$from = "";
$subject = "";
$headers = "";
$message = "";
$is_header= true;

//loop through each line
for ($i=0; $i < count($lines); $i++) {
if ($is_header) {
// hear information. instead of main message body, all other information are here.
$headers .= $lines[$i]."\n";

// Split out the subject portion
if (preg_match("/^Subject: (.*)/", $lines[$i], $matches)) {
$subject = $matches[1];
}
//Split out the sender information portion
if (preg_match("/^From: (.*)/", $lines[$i], $matches)) {
$from = $matches[1];
}
} else {
// content/main message body information
$message .= $lines[$i]."\n";
}
if (trim($lines[$i])=="") {
// empty line, header section has ended
$is_header = false;
}
}

Currently, the variable $email returns:

"Person name" <person@domain.net>

How can I modify this variable to only get the email portion?

Secondly, the variable message returns a whole pile of data including formatting and tags as below:

This is a multipart message in MIME format.

Content-Type: text/plain;

. I want to extract only the content of my body in plain text. so if body of email was simply 'testing' then I want the variable to return testing?

Help appreciated as always.

Thanks again.

edit as per @hakra

#!/usr/local/bin/php -q

<?php 
// read from stdin 
$fd = fopen("php://stdin", "r"); 
$email = ""; 
while (!feof($fd)) { 
$email .= fread($fd, 1024); 
} 
fclose($fd); 

// handle email 

$lines = explode("\n", $email); 

// empty vars 

$from = ""; 
$subject = ""; 
$headers = ""; 
$message = ""; 
$splittingheaders = true; 

for ($i=0; $i < count($lines); $i++) { 
if ($splittingheaders) { 
// this is a header 
$headers .= $lines[$i]."\n"; 
// look out for special headers 
if (preg_match("/^Subject: (.*)/", $lines[$i], $matches)) { 
$subject = $matches[1]; 
} 
if (preg_match("/^From: (.*)/", $lines[$i], $matches)) { 
$from = $matches[1]; 
} 
} else { 
// not a header, but message 
$message .= $lines[$i]."\n"; 
} 

if (trim($lines[$i])=="") { 
// empty line, header section has ended 
$splittingheaders = false; 
} 
} 



$buffer = [$email] // Mail Content from Pipe 

$mail = mailparse_msg_create(); 
mailparse_msg_parse($mail, $buffer); 
$struct = mailparse_msg_get_structure($mail);  

foreach ($struct as $st) {  
    $section = mailparse_msg_get_part($mail, $st);  
    $info    = mailparse_msg_get_part_data($section);  
 }

 ?>

回答1:

You can parse address lines with imap_rfc822_parse_adrlistDocs or mailparse_rfc822_parse_addressesDocs.

To parse the body of the email message, you can make use of the Mail Parse extensionDocs:

$buffer = [...] // Mail Content from Pipe

$mail = mailparse_msg_create();
mailparse_msg_parse($mail, $buffer);
$struct = mailparse_msg_get_structure($mail); 

foreach ($struct as $st) { 
    $section = mailparse_msg_get_part($mail, $st); 
    $info    = mailparse_msg_get_part_data($section); 

    print_r($info);
}
