Print next array keys in array of arrays - php

Question

I have an array of arrays that contain array key with the value, here the example :
Array (
[0] => Array ( [Hotel] => N [Jayakarta] => NE [Jaya] => NE [sangat] => ADV [nyaman] => ADJ [ditempati] => V. )
[1] => Array ( [Andi] => NOB [Hotel] => N [menginap] => V [disana] => N [selama] => N [satu] => NUM [minggu] => N. )
)
I want to make an output if I found a key of "Hotel" then I will print next key from "Hotel". For example :
Hotel Jayakarta Jaya
Hotel menginap disana
Here's what I am doing for the moment:
foreach($token2 as $index => $tok){
foreach ($tok as $tokkey => $tokvalue) {
if ($tokkey == "Hotel" and $tokvalue == "N"){
echo $tokkey . " " ;
while($cek == true && $x <= 2){
$next = next($tok);
echo key($tok). " " ;
$x++;
}
echo ", ";
$x = 1;
}
}
}
And the output :
Hotel Jayakarta jaya sangat , Hotel Hotel menginap
The Expected Output should be as below:
Hotel Jayakarta jaya sangat , Hotel menginap disana selama
Any help is much appreciated, Thank you.

Answer 1

Do something like following:
$i = 3;
foreach($token2 as $index => $tok){
foreach ($tok as $tokkey => $tokvalue) {
if ($tokkey == "Hotel" && $tokvalue == "N"){
echo $tokkey . " " ;
$i = 1;
}
else if($i < 3){
echo $tokkey . " ";
$i++;
}
}
echo ", ";
}

maybe you could try this ?
$arrayOfHotels = array(0 => array('Hotel' => 'N' , 'Jakarta' => 'NE', 'Jaya' => 'NE', 'sangat' => 'ADV', 'nyaman' => 'ADJ', 'ditempati' => 'V.'),1 => array('Andi' => 'NOB', 'Hotel' => 'N', 'menginap' => 'V', 'disana' => 'N', 'selama' => 'N', 'satu' => 'NUM', 'minggu' => 'N.'));
echo '<pre>';
print_r(findHotel($arrayOfHotels));
echo '</pre>';
function findHotel($hotels)
{
$isHotelFind = false;
$isFirstThrough = true;
foreach($hotels as $row => $value)
{
foreach ($value as $row2 => $value2)
{
if($row2 == "Hotel" && $value = 'N' && !$isHotelFind)
{
if($isFirstThrough)
{
echo $row2 . " ";
}
else
{
echo ", " . $row2 . " ";
}
$isHotelFind = true;
$isFirstThrough = false;
}
if($isHotelFind && $row2 != "Hotel")
{
echo $row2 . " ";
}
}
$isHotelFind = false;
}
}

You can use array_search to find your key and remove leading elements before it.
$array = [
[
"Hotel" => 'N',
"Jayakarta" => 'NE',
'Jaya' => 'NE',
'sangat' => 'ADV',
'nyaman' => 'ADJ',
'ditempati' => 'V.'
]
,
[
"Andi" => 'NOB',
"Hotel" => 'N',
'menginap' => 'V',
'disana' => 'N',
'selama' => 'N',
'satu' => 'NUM',
'minggu' => 'N.'
]
];
foreach ($array as $data) {
// Find index to start
$index = array_search("Hotel", array_keys($data));
// Remove other keys
$new_array_starting_hotel = array_splice($data, $index, count($data));
// merge results
$merged[] = implode(' ', array_keys($new_array_starting_hotel));
}
print_r($merged);
And output will be like:
Array
(
[0] => Hotel Jayakarta Jaya sangat nyaman ditempati
[1] => Hotel menginap disana selama satu minggu
)
You can merge or implode all however you like.
