Breaking out of loop in PHP and resetting the counters - php

Question

There is some logic error in my code and I am not sure what I am doing wrong here.
Setting up things first, I have a .json file that I am reading which is in this layout:
So the polygon element is at every 1, 3, 5, .. and the school name is one prior to that.
Now I have another .csv file from where I am taking different lat and long values. Basically I have to see if that lat long from the csv file is inside any of these polygons as described in the json file.
Here is my part of the PHP code that takes in the json file and csv file. My logic is that, I take one lat and long value from the CSV and then want to go over each polygon in the json file.
If you follow the code below, I take in the values and when I meet the condition that it is outside a polygon, it just breaks out of the second while loop, takes another set of lat and longs.
$string = file_get_contents("Schools.json", 0, null, null);
$json_a = json_decode($string, true);
$start_row = 4;
$rowID = 1;
$polygonIndex = 1;
$insideCheck = 0;
$file = fopen("ActiveProperty.csv", "r");
while (($row = fgetcsv($file)) !== FALSE){
if($rowID >= $start_row){
$points = array($row[52] . ' ' . $row[49]);
$polygonIndex = 1;
while ($polygonIndex < 454){
$polygon = $json_a[$polygonIndex]['Polygons'];
foreach($points as $key => $point) {
if ($pointLocation->pointInPolygon($point, $polygon) == "outside"){
echo "point " . ($key+1) . " ($point): " . $pointLocation->pointInPolygon($point, $polygon);
echo "<br>";
$polygonIndex = $polygonIndex + 2;
echo $polygonIndex;
$insideCheck = 0;
break;
}
else {
echo $json_a[$polygonIndex - 1];
echo "<br>";
echo "point " . ($key+1) . " ($point): " . $pointLocation->pointInPolygon($point, $polygon);
echo "<br>";
$insideCheck = 1;
break;
}
}
if ($insideCheck = 0) {
echo "out of foreach 0";
continue;
}
else {
echo "out of foreach";
$insideCheck = 0;
break;
}
}
}
$rowID++;
}
Here is a sample output that I have:
Lat and longs in this image is from the csv file.
The expected output should be that with that lat and long, it should go over the polygons in the json and if its inside, return the first element which is the school. Here $polygonIndex just stays 3 which I am guessing is the issue.
If this is still unclear what I am trying to do, please let me know. Thanks.
