imap_delete not working - php

Question

I am using php imap functions to parse the message from webmail. I can fetch messages one by one and save them in DB. After saving, I want to delete the inbox message. imap_delete function is not working here. My code is like that:
$connection = pop3_login($host,$port,$user,$pass,$folder="INBOX",$ssl=false);//connect
$stat = pop3_list($connection);//list messages
foreach($stat as $line) {
//save in db codes...
imap_delete($connection, $line['msgno']);//flag as delete
}
imap_close($connection, CL_EXPUNGE);
I also tested - imap_expunge($connection);
But it is not working. The messages are not deleted. Please help me out...

Answer 1

You are mixing POP and IMAP.
That is not going to work. You need to open the connection with IMAP. See this example:
<?php
$mbox = imap_open("{imap.example.org}INBOX", "username", "password")
or die("Can't connect: " . imap_last_error());
$check = imap_mailboxmsginfo($mbox);
echo "Messages before delete: " . $check->Nmsgs . "<br />\n";
imap_delete($mbox, 1);
$check = imap_mailboxmsginfo($mbox);
echo "Messages after delete: " . $check->Nmsgs . "<br />\n";
imap_expunge($mbox);
$check = imap_mailboxmsginfo($mbox);
echo "Messages after expunge: " . $check->Nmsgs . "<br />\n";
imap_close($mbox);
?>

Actually the functions names are like pop3. but they perform imap functionality. like -
function pop3_login($host,$port,$user,$pass,$folder="INBOX",$ssl=false)
{
$ssl=($ssl==false)?"/novalidate-cert":"";
return (imap_open("{"."$host:$port/pop3$ssl"."}$folder",$user,$pass));
}
function pop3_list($connection,$message="")
{
if ($message)
{
$range=$message;
} else {
$MC = imap_check($connection);
$range = "1:".$MC->Nmsgs;
}
$response = imap_fetch_overview($connection,$range);
foreach ($response as $msg) $result[$msg->msgno]=(array)$msg;
return $result;
}
