Query arrays using php - php

Question

I have an array of imported data:
array(3) {
[1234]=>
array(2) {
["item"]=>
string(6) "scotch"
["type"]=>
string(6) "Spirit"
}
[5678]=>
array(2) {
["item"]=>
string(4) "wine"
["type"]=>
string(7) "Vintner"
}
[9012]=>
array(2) {
["item"]=>
string(11) "soft drinks"
["type"]=>
string(3) "Pop"
}
}
I'm trying to make it say "Its in the Spirit section under code 1234"
I'm new to php so not sure I'm writing the for loop if function correctly. I keep getting "We are out of stock". Man I need a whisky. Help please
my code:
<?php
$row = 1;
$sheet1 = [];
if (($handle = fopen("sheet1.csv", "r")) !== FALSE) {
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
$sheet1[$data[0]] = [];
$sheet1[$data[0]]['item'] = $data[1];
$sheet1[$data[0]]['type'] = $data[2];
$row++;
}
fclose($handle);
}
var_dump($sheet1);
$string = 'Where is scotch in shop';
echo $string;
$words = explode(' ', $string);
print_r($words);
for ($i = 0; $i < count($words); ++$i) {
if (isset($sheet1[$words[$i]]['item'])) {
echo "Its in the ".$sheet1[$words[$i]]['type']." section marked
under code ".$sheet1[$words[$i]]['key'];
}
}
echo "We are out of stock";
?>

If you change it to a foreach and then check for the existance of the word using in_array() it all looks a litle easier to understand.
foreach ($sheet1 as $key=>$sheet) {
if ( in_array($sheet['item'], $words) ) {
echo "Its in the {$sheet['type']} section marked under code $key";
}
}
Result
Its in the Spirit section marked under code 1234
