and so on for may occurances
Now i want to get the details to an html table ,its almost done but the problem is
pricedetails array.
Here is the code for getting pricedetails
foreach ($data['prizes'] as $prizes) {
foreach($prizes as $prize){
echo '<pre>';
print_r($prize);
echo '</pre>';
$temp=$prize['prizeticket'];
foreach($temp as $ticket){
print_r($ticket);
}
}
}
Here is the two iterations of Print_r($prize)
Array
(
[prizeno] => 1
[prizedesc] => Rs :6,500,000/-
[totalamt] => 6500000
[conslation] => f
[prizeticket] => Array
(
[seriesname] => AK
[digit] => 279045
[district] => THRISSUR
)
)
Array
(
[prizeno] => 1
[prizedesc] => Rs :10,000/-
[totalamt] => 10000
[conslation] => t
[prizeticket] => Array
(
[0] => Array
(
[seriesname] => AJ
[digit] => 279045
[district] => NIL
)
[1] => Array
(
[seriesname] => AR
[digit] => 279045
[district] => NIL
)
[2] => Array
(
[seriesname] => AM
[digit] => 279045
[district] => NIL
)
[3] => Array
(
[seriesname] => AO
[digit] => 279045
[district] => NIL
)
[4] => Array
(
[seriesname] => AP
[digit] => 279045
[district] => NIL
)
[5] => Array
(
[seriesname] => AL
[digit] => 279045
[district] => NIL
)
)
)
As you see the first iteration contains only one sub array under prizedetails and the second iterations contains more than one sub arrays under prizedetails.
The problem i can't get the values with both key-value pairs.
print_r($ticket) output
AK
279045
THRISSUR
Array
(
[seriesname] => AJ
[digit] => 279045
[district] => NIL
)
Array
(
[seriesname] => AR
[digit] => 279045
[district] => NIL
)
Notice that first output AK
279045
THRISSUR
printed without any key and its like a text and the rest is outputted correctly,but i need to print all of with the array keys.I know this is because the print_r($prize) first iteration contains only one sub array under prizedetails.How can i solve it?
UPDATE
Code for parsing xml
$data=json_decode(json_encode((array)simplexml_load_string($lottery)),1);

Answer 1

Your code is behaving correctly. You need to alter the code such that "IF" prizeticket has one item, it does one thing, "ELSE" it does something else.
if(!isset($prize['prizeticket'][0])) // It has one item
print_r($prize['prizeticket']);
else foreach($prize['prizeticket'] as $ticket)
print_r($ticket);
This is a good place to use a function. Suppose it was named `handle_a_ticket($ticket)', you would replace print_r with handle_a_ticket.

Answer 2

My first reaction is that the XML has a typo.
[prizeticket] => Array
(
[seriesname] => AK
[digit] => 279045
[district] => THRISSUR
)
Should instead look like:
[prizeticket] => Array
(
[0] => Array
(
[seriesname] => AK
[digit] => 279045
[district] => THRISSUR
)
If you have some requirement that you absolutely must leave the XML the way it is, I'd suggest checking for the existence of index 0 like this:
foreach($temp as $tickets) {
if(!isset($tickets[0]) {
//do something with $ticket
}
else {
foreach($tickets as $ticket) {
//do something with $ticket
}
}

Answer 3

Finally i found the solution based on #RiggsFolly's comments.
$xml=simplexml_load_file('AK-194.xml');
foreach($xml->prizes as $prize){
foreach($prize->prizedetails as $details){
foreach($details->prizeticket as $tickets){
print_r($tickets);
}
}
}
