Notice Undefined Offset

[jmr3460]

Hey all,

I have been working on a Blaclberry app that sends me an email with coord., timestamp and I can add some more. I have been able to open each of the emails with my new script. My goal is to insert the variables I have into a database. All this now is possible except I am getting a notice where there is an empty line of the email body.

The bodies of the email look like this:

Name: in

Latitude: XX.XXXXX

Longitude: -XX.XXXXXX

Altitude: 108m

Timezone:

Date: Apr 6, 2011 7:42 AM

Description: office

 

Address:

Address2:

City:

State:

Country:

Postal Code:

URL:

Phone Number:

 

Sent on the Sprint® Now Network from my BlackBerry®

The undefined offsets show up after Description and after Phone number.

 

This is what my script does:

 

Name: in

Latitude: 35.12063

Longitude: -89.95295

Altitude: 108m

Timezone:

Date: Apr 6, 2011 7:42 AM

Description: office

Notice: Undefined offset: 1 in /home3/simplic5/public_html/gps/gps.php on line 20

This is my script:

<?php
ini_set ("display_errors", "1");
error_reporting(E_ALL);
//open database
$connection = imap_open("{mail.mailbox.com:143}INBOX", "mark@abc.com", "password");
    $message_number = imap_num_msg($connection);
    $headers = imap_headers($connection);
    $count = count($headers);
    for($i=1;$i<=$count;$i++){
$headerinfo = imap_base64(imap_body($connection, $i));

  	$message = nl2br($headerinfo);
  	$remove_2br = str_replace('<br />\n', '<br />', $message);
  	$messages = explode('<br />', $remove_2br);
  	$num_lines = (count($messages)-1);
for($a=0;$a< $num_lines;$a++){
//echo $messages[$a]."<br />";
$data = explode(': ',$messages[$a]);
$column = $data[0];
$field = $data[1];
echo $column.": ".$field."<br />\n";
//create sql to insert $field into $column
$sql = "";
}
}
?>

 

I think that the notice is generated because of the blank line in the email text. I only need about 4 or 5 bits of information.

Is there something I can do to delete the blank lines first, then I can process the rest of the email per the script?

Thanks for any help!

Right, it'll do that every time there's a line without ": " in it, because explode() will only return an array with one member, so [1] doesn't exist. Here's a simple fix:

for($a=0;$a< $num_lines;$a++){
if(strpos($messages[$a], ": ") === false) continue;

By the way, if the lines are separated only by "\n" (or "\r\n"), why not just explode the string by that?

Thanks your fix did it. The lines are coming from a blackberry browser and sent to my server via email. when I view the code there are <br /> at the end of every line. I just assumed the \n was there as well.

Anyway the next step is to create my database table and insert some data. Thanks very much for the help.
