JSON to Database with php - php

Question

So I have this JSON for example
{
"top" : [
{
"info" : {
"ID" : 0,
"TID" : 1
},
"geo" : {
"poins" : [
[
[
-5.9,
57.1
],
[
-5.99,
57.0
]
]
]
}
},
{
"info" : {
"ID" : 1,
"TID" : 2
},
"geo" : {
"points" : [
[
[
-5.4,
57.0
],
[
-5.9,
57.0
]
]
]
}
}
]
}
I need to put this information in the DataBase with php
So I have a colum in the DB called points and it need the data inside to be looking like:
[-5.4, 57.0],[-5.9, 57.0]
I have a columb with ID so all I need is to put the points from the JSON for every ID
My php should be loking like:
connection to the database
$str = file_get_contents(the JSON);
$json = json_decode($str, true);
foreach ($json['top'] as $field) {
query='UPDATE poins_table
SET points='$field['geo']['points']'
WHERE ID='$field['info']['ID']' '
}
The code seems to be not working. What I am missing ...Any siggestions will be helpfull. Thank you

You could try following:
<?php
$str = file_get_contents('the JSON URL');
$json = json_decode($str, true);
try{
$db = new PDO("dbtype:host=yourhost;dbname=yourdbname;charset=utf8","username","password");
$query = $db->prepare('UPDATE poins_table SET points=? WHERE ID=?');
foreach ($json['top'] as $field) {
$query->execute(array(json_encode($field['geo']['points']), $field['info']['ID']));
}
} catch(PDOException $e) {
echo "Error: ". $e;
}
?>
