Sorting XML with SimpleXML/XPath?

Closed 9 years ago.
I am having a little trouble with an xml feed (atom). I am running a for each loop to return prices using simple xml and converting them too arrays which works fine below :-
foreach ($dc->departures->departure as $price)
{
$lowest = $price->prices->price[5]->asXML();
$lowestval = array($lowest);
print_r($lowestval);
}
Which is returning :-
Array ( [0] => 2289 )
Array ( [0] => 2207 )
Array ( [0] => 2369 )
Array ( [0] => 2229 )
My goal is to return only the lowest price, so I can display a Prices From: area. From what I understand I need to use the min() function, however this only works with one array with several values. I've tried array_merge which doesn't seem to work and just returns the same as above. I am a PHP newbie so there maybe something obvious. A kick in the correct direction would be appreciated.

Answer 1

Try this. Its working fine
<?php
foreach ($dc->departures->departure as $price)
{
$lowest = $price->prices->price[5]->asXML();
$lowestval[] = $lowest;
}
$min = min($lowestval);
echo $index = array_search($min, $array);
?>

Answer 2

$data = array();
$data[] =Array (0 => 2289 ) ;
$data[] = Array ( 0 => 2207 ) ;
$data[] = Array ( 0 => 2369 ) ;
$data[] = Array ( 0 => 2229 );
array_multisort($data);
$first = array_shift($data);
var_dump($first); // 2207

You can also use 'sort()' function to sort an array value.
Here is an example with some extra value as well merge array.
$arry1 = array(
array(5),
array(10000),
array(2289),
array(2288),
array(2207),
array(2369),
array(2229),
array(5421),
array(541)
);
$arry2 = array(
array(456789),
array(54564)
);
$arry1 = array_merge($arry1,$arry2);
sort($val);
echo '<pre>';
print_r($val);
echo '</pre>';
then you can use first element of an array as min value.
echo $arry1[0][0];
