Getting data out of an array

[passagewds]

Why won't the below lines echo the value in $singleuser to the screen?

$fh = fopen($file, "r");
    while ($info = fgets($fh, 4096)) {
	ereg ("(.*)(:)(.*)", $info, $username);	
               	$singleuser = $username[1];
	$singlepass = $username[3];

$users[] = array($singleuser, $singlepass);

echo "$users[0] <br>";

            } //endwhile

fclose($fh);

Because $users[0] is an array and not the values you think it is.

$users[0][0] and $users[0][1] have the values of the 2 variables.

that didn't work.... now I get

Array[0]

as an output.

The solution was

$users = array("$singleuser", "$singlepass");

I wish all the problems were that easy to solve

[tbach2]

$fh = fopen($file, "r");
    while ($info = fgets($fh, 4096)) {
	ereg ("(.*)(:)(.*)", $info, $username);	
               	$singleuser = $username[1];
	$singlepass = $username[3];

$users[] = array($singleuser, $singlepass);

echo "$users[0] <br>";

            } //endwhile

fclose($fh);


// find out what is in array
print "<pre>";
print_r($users);
print "</pre>";

debug with print_r()

also, personal preference here, makes the array more meaningful to me:

$users[] = array('user' => $singleuser,
                 'pass' => $singlepass
                 );

and to get the values back out,

for($i=0;$i<sizeof($users);$i++) {
   printf("user: %s<br>pass: %s<hr>",
          $users[$i]['user'],
          $users[$i]['pass']
          );
}
