Something appears to be amiss, as your array couldn't contain multiple
items with the specialservice key (I'm assuming the second key
'secialservice' is just a typo), as any subsequent assignments would
overwrite the previous value.

This will never work. Your last array will always overwrite your
previous array.
Here is how I would suggest building it:
$items = array(
1 => array(
serviceid => 1,
servicename=> signature required,
price => $4.95
),
15 => array(
serviceid => 15,
servicename => return receipt,
price => $2.30
)
)
This will ensure that your first level indexes never overwrite themselves.
But, with that change made, then do this:
foreach ( $items AS $item ) {
if ( array_key_exists('price', $item) ) {
echo $item['price'];
} else {
echo 'Item does not have a price set';
}
}

Hi Adam,
Actually you are correct. Sorry to confuse.
Its an XML response from the USPS api I am going through, which I am
converting to an array.
Here is the response that I am trying to convert to a multidimensional
array.

This is my attempt to convert. I thought of setting up a blank array
then filling that array with the specialservice arrays
$data = strstr($result, '<?');
// echo '<!-- '. $data. ' -->'; // Uncomment to show XML in comments
$xml_parser = xml_parser_create();
xml_parser_set_option($xml_parser,XML_OPTION_TARGET_ENCODING,
"ISO-8859-1");
xml_parse_into_struct($xml_parser, $result, $vals, $index);
xml_parser_free($xml_parser);
$params = array();
$level = array();
foreach ($vals as $xml_elem) {
if ($xml_elem['type'] == 'open') {
if (array_key_exists('attributes',$xml_elem)) {
list($level[$xml_elem['level']],$extra) =
array_values($xml_elem['attributes']);
} else {
$level[$xml_elem['level']] = $xml_elem['tag'];
}
}
if ($xml_elem['type'] == 'complete') {
$start_level = 1;
$php_stmt = '$params';
while($start_level < $xml_elem['level']) {
$php_stmt .= '[$level['.$start_level.']]';
$start_level++;
}
$php_stmt .= '[$xml_elem[\'tag\']] = $xml_elem[\'value\'];';
eval($php_stmt);
}
}
... then trying to pull data from the results of the $php_stmt
$sid = array();
$numserv = count($params['RATEV4RESPONSE'][''.$p.$ack.''][$cId]
['SPECIALSERVICES']);
if($numserv > 0) {
foreach($params['RATEV4RESPONSE'][''.$p.$ack.''][$cId]
['SPECIALSERVICES']['SPECIALSERVICE'] as $sp_servs) {
$sid_val = $sp_servs['SERVICEID'];
if(in_array($sid_val, $sid)) {
return;
} else {
if($sp_servs['AVAILABLEONLINE'] == true) {
$extracost += $sp_servs['PRICEONLINE'];
} else {
$extracost += $sp_servs['PRICE'];
}
$sid[$i] = $sid_val;
}
}
}
echo("<br><br>Services Array :<br>");
$num_array_items = count($sid);
for($i=0; $i < $num_array_items; $i++) {
echo($i.". ".$sid[$i]."<br>");
}

Thanks Jim,
However I have no control over how the USPS sends back the response.
See my more detailed email.

Never mind. I found a different function that reads out the children
as well into the array.
function xml_parse_into_assoc($data) {
$p = xml_parser_create();
xml_parser_set_option($p, XML_OPTION_CASE_FOLDING, 0);
xml_parser_set_option($p, XML_OPTION_SKIP_WHITE, 1);
xml_parse_into_struct($p, $data, $vals, $index);
xml_parser_free($p);
$levels = array(null);
foreach ($vals as $val) {
if ($val['type'] == 'open' || $val['type'] ==
'complete') {
if (!array_key_exists($val['level'], $levels)) {
$levels[$val['level']] = array();
}
}
$prevLevel =& $levels[$val['level'] - 1];
$parent = $prevLevel[sizeof($prevLevel)-1];
if ($val['type'] == 'open') {
$val['children'] = array();
array_push(&$levels[$val['level']], $val);
continue;
}
else if ($val['type'] == 'complete') {
$parent['children'][$val['tag']] = $val['value'];
}
else if ($val['type'] == 'close') {
$pop = array_pop($levels[$val['level']]);
$tag = $pop['tag'];
if ($parent) {
if (!array_key_exists($tag,
$parent['children'])) {
$parent['children'][$tag] = $pop['children'];
}
else if (is_array($parent['children'][$tag])) {
if(!isset($parent['children'][$tag][0])) {
$oldSingle = $parent['children'][$tag];
$parent['children'][$tag] = null;
$parent['children'][$tag][] =
$oldSingle;
}
$parent['children'][$tag][] =
$pop['children'];
}
}
else {
return(array($pop['tag'] => $pop['children']));
}
}
$prevLevel[sizeof($prevLevel)-1] = $parent;
}
}
$params = xml_parse_into_assoc($result);//$result = xml result from
USPS api
Original function by: jemptymethod at gmail dot com
Duplicate names fix by: Anonymous (comment right above original
function)

I have the following:
$dsn = "mysqli://$username:$password@$hostname2/$database";
$options = array(
'debug' => 3,
'result_buffering' => false,
);
$dbh =& MDB2::factory($dsn, $options);
if (PEAR::isError($mdb2))
{
die($mdb2->getMessage());
}
function tallyCart($_u_id,$dbh){
while($row = $result->fetchrow(MDB2_FETCHMODE_ASSOC)) {
$_showCheckOut=1;
$_pdetail=new ProductDetail($row{'product_ID'},
$row{'product_Quantity'}, $_u_id);
$_getSubTotal += $_pdetail->_subTotal;
$_counter++;
}
}
I'm getting: Call to undefined method MDB2_Error::fetchrow()
anyone have any ideas? Can I not pass a database handle to a function?
Thanks,
Curtis
