Uhh... What's happening here??

[tguill]

This is my code :

<?php

$merchant_0 = array('id' => '22',
                    'merchant_id' => '3',
                    'price' => '199.95'
                   );

$merchant_1 = array('id' => '32',
                    'merchant_id' => '3',
                    'price' => '205.95'
                   );

$merchant_2 = array('id' => '65',
                    'merchant_id' => '5',
                    'price' => '212.95'
                   );
$merchant_3 = array('id' => '41',
                    'merchant_id' => '5',
                    'price' => '212.95'
                   );
$merchant_4 = array('id' => '67',
                    'merchant_id' => '5',
                    'price' => '212.95'
                   );
$merchant_5 = array('id' => '87',
                    'merchant_id' => '7',
                    'price' => '212.95'
                   );
$merchant_6 = array('id' => '33',
                    'merchant_id' => '8',
                    'price' => '212.95'
                   );
$merchant_7 = array('id' => '19',
                    'merchant_id' => '9',
                    'price' => '212.95'
                   );
$merchant_8 = array('id' => '9',
                    'merchant_id' => '10',
                    'price' => '212.95'
                   );

$array = array($merchant_0,$merchant_1,$merchant_2,$merchant_3,$merchant_4,$merchant_5,$merchant_6,$merchant_7,$merchant_8);

print_r(array_values($array));

 echo '<BR>--<BR>';

for ($i=0, $n=sizeof($array); $i<$n; $i++) {

echo $array[$i][merchant_id];

$merchants[] .= $array[$i][merchant_id];

}

 echo '<BR>--<BR>';

print_r(array_values($merchants));

$merchants_unique = array_unique($merchants);

 echo '<BR>--<BR>';

print_r(array_values($merchants_unique));

 echo '<BR><BR>Begin<BR>';

for ($i=0, $n=sizeof($merchants_unique); $i<$n; $i++) {

 echo '* ';

echo $merchants_unique[$i];

 echo ' *<BR>'; 
}
 echo 'End<BR>';

?>

I'm Getting This as a result:

Array ( [0] => Array ( [id] => 22 [merchant_id] => 3 [price] => 199.95 ) [1] => Array ( [id] => 32 [merchant_id] => 3 [price] => 205.95 ) [2] => Array ( [id] => 65 [merchant_id] => 5 [price] => 212.95 ) [3] => Array ( [id] => 41 [merchant_id] => 5 [price] => 212.95 ) [4] => Array ( [id] => 67 [merchant_id] => 5 [price] => 212.95 ) [5] => Array ( [id] => 87 [merchant_id] => 7 [price] => 212.95 ) [6] => Array ( [id] => 33 [merchant_id] => 8 [price] => 212.95 ) [7] => Array ( [id] => 19 [merchant_id] => 9 [price] => 212.95 ) [8] => Array ( [id] => 9 [merchant_id] => 10 [price] => 212.95 ) )

Array ( [0] => 3 [1] => 3 [2] => 5 [3] => 5 [4] => 5 [5] => 7 [6] => 8 [7] => 9 [8] => 10 )

Array ( [0] => 3 [1] => 5 [2] => 7 [3] => 8 [4] => 9 [5] => 10 )

Begin
3

5


7
End

---

What is happening inbetween the "Begin' and 'End' ?????

I want it to look like :

Begin
3
5
7
8
9
10
End

I thought it should, but I can't figure out what is going on!

Thanks in advance!

Replace the last loop with this one instead:

foreach($merchants_unique as $index=>$value) {

echo '* ';

echo $value;

echo ' *<BR>';
}

=== OR ===

You can just add this line before the exisiting loop:

$merchants_unique = array_values($merchants_unique);

The reason it wasn't working is because the indexes in merchants_unique are not sequential (0, 1, 2, ....) after the array_unique call.
