how to Display values from nested array - php

Question

Please help me to extract and display the values from this array..
This is the output when I do a print_r($array); :
Array
(
[0] => SPD Object
(
[DRIVERNAME] => SPD Barry
[STARTTIME] => 07:44
[FINISHTIME] => 18:12
[STOP] =>
[SEQUENCENO] => 37
[PLACENAME] => AMSTERDAM ZUIDOOST
[ARRIVALTIME] => 17:32
)
[1] => SPD Object
(
[DRIVERNAME] => SPD Brady
[STARTTIME] => 07:36
[FINISHTIME] => 15:53
[STOP] =>
[SEQUENCENO] => 32
[PLACENAME] => NIEUWEGEIN
[ARRIVALTIME] => 15:30
)
[2] => SPD Object
(
[DRIVERNAME] => SPD Bram
[STARTTIME] => 08:11
[FINISHTIME] => 18:32
[STOP] =>
[SEQUENCENO] => 32
[PLACENAME] => LAGE ZWALUWE
[ARRIVALTIME] => 17:28
)
)
What I want to do is, get this Driver Name and Sequence Number and echo them.
UPDATE :
My full code can be found below.
I get a xml file which contain this kind of stuff :
<TRIP>
<DRIVERNAME>SPD Barry</DRIVERNAME>
<STARTTIME>07:44</STARTTIME>
<FINISHTIME>18:12</FINISHTIME>
<STOP>
<SEQUENCENO>1</SEQUENCENO>
<PLACENAME>ROTTERDAM</PLACENAME>
<ARRIVALTIME>08:30</ARRIVALTIME>
</STOP>
</TRIP>
Here is my PHP file to collect data into an array.
<?php
class SPD {
function SPD ($aa) {
foreach ($aa as $k=>$v)
$this->$k = $aa[$k];
}
}
function readDatabase($filename) {
// read the XML database of aminoacids
$data = implode("", file($filename));
$parser = xml_parser_create();
xml_parser_set_option($parser, XML_OPTION_CASE_FOLDING, 0);
xml_parser_set_option($parser, XML_OPTION_SKIP_WHITE, 1);
xml_parse_into_struct($parser, $data, $values, $tags);
xml_parser_free($parser);
// loop through the structures
foreach ($tags as $key=>$val) {
if ($key == "TRIP") {
$molranges = $val;
// each contiguous pair of array entries are the
// lower and upper range for each molecule definition
for ($i=0; $i < count($molranges); $i+=2) {
$offset = $molranges[$i] + 1;
$len = $molranges[$i + 1] - $offset;
$tdb[] = parseMol(array_slice($values, $offset, $len));
}
} else {
continue;
}
}
return $tdb;
}
function parseMol($mvalues) {
for ($i=0; $i < count($mvalues); $i++) {
$mol[$mvalues[$i]["tag"]] = $mvalues[$i]["value"];
}
return new SPD($mol);
}
$db = readDatabase("test.xml");
if(is_array($db)){
foreach($db as $item) {
echo $item->DRIVERNAME;
echo $item->SEQUENCENO;
}
}
?>
What I want to do is, echo Driver name and Sequence Number :)

This should do it :
<?php
class SPD {
function SPD($aa) {
foreach ($aa as $k => $v)
$this->$k = $aa[$k];
}
}
function readDatabase($filename) {
// read the XML database of aminoacids
$data = implode("", file($filename));
$parser = xml_parser_create();
xml_parser_set_option($parser, XML_OPTION_CASE_FOLDING, 0);
xml_parser_set_option($parser, XML_OPTION_SKIP_WHITE, 1);
xml_parse_into_struct($parser, $data, $values, $tags);
xml_parser_free($parser);
// loop through the structures
foreach ($tags as $key => $val) {
if ($key == "TRIP") {
$molranges = $val;
// each contiguous pair of array entries are the
// lower and upper range for each molecule definition
for ($i = 0; $i < count($molranges); $i+=2) {
$offset = $molranges[$i] + 1;
$len = $molranges[$i + 1] - $offset;
$tdb[] = parseMol(array_slice($values, $offset, $len));
}
} else {
continue;
}
}
return $tdb;
}
function parseMol($mvalues) {
for ($i = 0; $i < count($mvalues); $i++) {
if(isset($mvalues[$i]["value"])) {
$mol[$mvalues[$i]["tag"]] = $mvalues[$i]["value"];
}
}
return new SPD($mol);
}
$db = readDatabase("test.xml");
if (is_array($db)) {
foreach ($db as $item) {
echo 'ITEM 1 : ' . "\n<br/>";
echo '---------------' . "\n<br/>";
echo 'DRIVERNAME : ' . $item->DRIVERNAME . "\n<br/>";
echo 'SEQUENCENO : ' . $item->SEQUENCENO . "\n\n<br/><br/>";
}
}
?>
