php - Merge Arrays from XML feed -

this question has answer here:

• sorting xml simplexml/xpath? 3 answers

i having little trouble xml feed (atom). running each loop return prices using simple xml , converting them arrays works fine below :-

foreach ($dc->departures->departure $price) {     $lowest = $price->prices->price[5]->asxml();     $lowestval = array($lowest);     print_r($lowestval); } 

which returning :-

array ( [0] => 2289 )  array ( [0] => 2207 )  array ( [0] => 2369 )  array ( [0] => 2229 ) 

my goal return lowest price, can display prices from: area. understand need use min() function, works 1 array several values. i've tried array_merge doesn't seem work , returns same above. php newbie there maybe obvious. kick in correct direction appreciated.

try this. working fine

<?php  foreach ($dc->departures->departure $price) {  $lowest = $price->prices->price[5]->asxml(); $lowestval[] = $lowest;  }  $min = min($lowestval); echo $index = array_search($min, $array); ?>
