Print next array after matching array - php

Question

I have an array of arrays that contain array key with the value, here the example :
$text = [
[
'Hotel' => 'N',
'Jayakarta' => 'NE',
'Jaya' => 'NE',
'sangat' => 'ADV',
'nyaman' => 'ADJ',
'ditempati' => 'V.'
]
,
[
'Andi' => 'NOB',
'menginap' => 'V',
'di' => 'PREP',
'Hotel' => 'N',
'Neo' => 'NE',
'Malioboro => 'NE',
'selama' => 'N',
'satu' => 'NUM',
'minggu' => 'N.'
]
];
And I have array prefix that contain :
$prefix = [ [0] => Hotel [1] => Hostel [2] => Losmen [3] => Motel [4] => Penginapan [5] => Pesanggrahan [6] => Pondok [7] => Wisma ]
If $prefix elements are in $text array then I will check next array value of text. If array value is N or NE then I will make an output from prefix text until the end of array that contain value N or NE.
Here's what I am doing for the moment:
foreach($text as $index => $tok){
foreach ($tok as $tokkey => $tokvalue) {
if(in_array($tokkey, $prefix)){
echo $tokkey;
$next = next($tok);
if($tokvalue == "N" or $tokvalue == "NE"){
echo key($tok);
}
}
}
}
The output I got :
Hotel Jayakarta, Hotel menginap
The expected output should be:
- Hotel Jayakarta Jaya
- Hotel Neo Malioboro selama
Any help is much appreciated, Thank you.

Below are the steps I followed to get the desired out put.
1) If tokkey present in prefix array, call a function.
2) Create a new array starting from the element which matches with prefix array.
3) Loop the new array and check for next value to be either 'N' or 'NE'
4) Display those keys from array.
foreach($text as $index => $tok){
foreach ($tok as $tokkey => $tokvalue) {
if(in_array($tokkey, $prefix)){
getKeys($tokkey,$tok);
echo "<br/>";
}
}
}
function getKeys($tokkey,$tok){
$flag = 0;
echo $tokkey.' ';
foreach($tok as $k=>$v){
if($k==$tokkey){
$flag = 1;
}
if($flag){
$new_array[$k]=$v;
}
}
foreach($new_array as $k=>$v){
$ff = next($new_array);
if(($ff == 'NE' || $ff == 'N')){
echo key($new_array).' ';
}
}
}
Out Put:
Hotel Jayakarta Jaya Hotel Neo Malioboro selama

From what I understand from your text, you need to replace your if() that only runs once, for a while() that runs while the next() string is NE or N.
foreach($text as $index => $tok){
foreach ($tok as $tokkey => $tokvalue) {
if(in_array($tokkey, $prefix)){
echo $tokkey;
next($tok);
while($tokvalue == "N" || $tokvalue == "NE")
{ echo key($tok);
next($tok);
$tokvalue = current($tok);
}
}
}
echo "\n";
}
}
