[Resolved] implode question

[bfuzze_98]

I'm having a problem extracting data from a text file. I imploded a series of arrays and wrote them to a text file. The code I'm using is:

$fname = $_SESSION["fname"];
$lname = $_SESSION["lname"];
$name = array($fname,$lname);
$fullname = implode(' ', $name);

The result:
fname1 lname1fname2 lname2fname3 lname4fname5 ...
Unfortunately, I can't extract the data correctly because there is no space between the 2nd and 3rd values, (lname1fname2 should be lname1 fname2), 3rd and 4th values, etc.
First I used a space (' ' vs. '') as the glue then I tried using a comma (,) but they don't affect the end of each entry. I noticed something in the manual about an implode function with an outerglue:

function implode_assoc($inner_glue,$outer_glue,$array,$skip_empty=false){
 $output=array();
 foreach($array as $key=>$item)
  if(!$skip_empty || $item){$output[]=$key.$inner_glue.$item;}
 return implode($outer_glue,$output);
}

but there's no function for how to explode this. How can I resolve this?

Maybe you should use [man]serialize[/man] and [man]unserialize[/man] instead of implode and explode? This changes almost everything into a string, which can be written into file, read from file and then turned into object (array) once again.

Thanks for the reply.

I tried to change serialize/unserialize, but I can't seem to get past the first set of values. In addition the array output only recognizes the first set of values.

Array ( [0] => fname1 [1] => lname1 )

but the text file reads:

a:2:{i:0;s:6:"fname1";i:1;s:6:"lname1";}a:2:{i:0;s:6:"fname2";i:1;s:6:"lname2";}

It looks like it is converting each set into separate arrays, storing 2 arrays, so how can I get it to move on to the next array?

Here is someof the code I'm using:

<?php
session_start();
$str = file_get_contents('messages/index.txt'); 
$name =unserialize($str);
$i = 0;
while ($i < count($name))	{
		$fname = $name[$i];
		$i++;
		$lname = $name[$i];
		$filename = 'messages/' . $fname . '_' . $lname . '.txt'; 
		$data = file_get_contents($filename);
		session_decode($data); 
		$fname = $_SESSION['fname'];
		$lname = $_SESSION['lname'];
		$date = $_SESSION['date'];
		$message = $_SESSION['message'];
		echo '
						<tr> 
	<td><div align="right">Name:</div></td>
	<td>' . $fname . ' ' . $lname . '</td>
						</tr>
						<tr> 
	<td><div align="right">Date:</div></td>
	<td>' . $date . '</td>
						</tr>
						<tr> 
	<td><div align="right">Message:</div></td>
	<td valign="top"><p>' . $message . '</p></td>
					</tr>';

}
?>

This is the output I get:

Name: fname1 lname1
Date: Wed May 25, 2005, 11:42 pm
Message: message11111111111111111111
Name: lname1

Date: Wed May 25, 2005, 11:42 pm
Message: message11111111111111111111

Thanks

I was able to find an alternative, thanks.
