single line text log file parsing - php

Question

So i have a log/txt file wich contains the following :
31 dec. 2014 11:56 - UserA: Hi31 dec. 2014 11:56 - UserB: Hi to you31 dec. 2014 11:56 - UserA: Whats your name?31 dec. 2014 11:57 - UserB: Nancy
Im trying to get this into a more readable format.....
So im trying the following :
<?php
//load the logfile
$txt_file = file_get_contents('test.txt');
$txtfile2 = preg_split( "/ ( |:) /", $txt_file );
$rows = explode("\n", $txtfile2[0]);
foreach($rows as $row => $data)
{
$row_data = explode(':', $data);
$info[$row]['when'] = $row_data[0];
$info[$row]['name'] = $row_data[1];
$info[$row]['description'] = $row_data[2];
//display data
echo ' WHEN: ' . $info[$row]['when'] . '<br />';
echo ' WHO: ' . $info[$row]['name'] . '<br />';
echo ' MESSAGE: ' . $info[$row]['description'] . '<br /><br />';
}
?>
This works partially....
When executed the output would be :
WHEN: 31 dec. 2014 11
WHO: 56 - UserA
MESSAGE: Hi
WHEN: 31 dec. 2014 11
WHO: 56 - UserB
MESSAGE: Hi to you
This is close to what i want, but as you can see, because im using the delimiter ":" it will also cut the time and place the minutes in the who.
How can i explode on the second ":" only?
i hope this makes sense?

See how this works for you
<?php
$filename = "logfile.txt"; //data file to open
$fp = fopen( $filename, "r" ) or die("Couldn't open $filename");
while ( ! feof( $fp ) )
{
$line = fgets( $fp, 1024 );
$line_array = preg_split("/[:-]+/", $line);
$line_timestamp = $line_array[0] . ":" . $line_array[1];
$line_user = $line_array[2];
$line_message = $line_array[3];
echo ' WHEN: ' . $line_timestamp . '<br />';
echo ' WHO: ' . $line_user . '<br />';
echo ' MESSAGE: ' . $line_message . '<br /><br />';
}
?>
