With Treat a string by transforming it into an array

Question

I get a string from the bank that way:

POLYGON((-22.886145457836463 -43.118764097835, -22.88643210096987 -43.118324215556555, -22.886694032959 -43.117846782351904, -22.886763222456636 -43.11767512097496, -22.886782990878046 -43.117605383540564, -22.886886775043237 -43.11763757004875, -22.887133879879073 -43.11891966595787, -22.88630360584699 -43.11942392125267, -22.886115805063966 -43.118823106433325, -22.886145457836463 -43.118764097835))

I only need the coordinates between the parentheses:

-22.886145457836463 -43.118764097835, -22.88643210096987 -43.118324215556555, -22.886694032959 -43.117846782351904, -22.886763222456636 -43.11767512097496, -22.886782990878046 -43.117605383540564, -22.886886775043237 -43.11763757004875, -22.887133879879073 -43.11891966595787, -22.88630360584699 -43.11942392125267, -22.886115805063966 -43.118823106433325, -22.886145457836463 -43.118764097835

With Coordinates I need to create an array:

{lat: -22.886145457836463, lng: -43.118764097835},
{lat: -22.88643210096987, lng: -43.118324215556555},
{lat: -22.886694032959, lng: -43.117846782351904}

and etc...

How do I do?

Answer 1

To extract this information, you need to work with 3 functions that are str_replace to remove what is unnecessary and then use explode creating a array through the spaces between the values and with Trim to remove the spaces initials and finals.

After that create a for at a pace 2 and do the new array from there having the keys lat and lng as requested in your question, minimal example:

<?php

$str = 'POLYGON((-22.886145457836463 -43.118764097835, -22.88643210096987
                -43.118324215556555, -22.886694032959 -43.117846782351904,
                -22.886763222456636 -43.11767512097496, -22.886782990878046
                -43.117605383540564, -22.886886775043237 -43.11763757004875,
                -22.887133879879073 -43.11891966595787, -22.88630360584699
                -43.11942392125267, -22.886115805063966 -43.118823106433325,
                -22.886145457836463 -43.118764097835))';

function array_final($str)
{
    $str = str_replace(['POLYGON','((','))'], [''], $str);
    $str = explode(" ", trim($str));
    $arrays = [];
    for($i = 0; $i < count($str); $i += 2)
    {
        $arrays[] = ['lat' => $str[$i], 'lng' => $str[$i+1]];
    }
    return $arrays;
}

var_dump(array_final($str));

ONLINE EXAMPLE

^{Observing: the Framework Larable which is written in php, will not solve all problems, especially the particular ones, often we need to brush code so that create certain solutions, which is in this case in specific.}
