array structure help in php to generate json - php

Question

Fetching data from mySQL and Generating json through php like this:
while ($row = mysql_fetch_array($result)) {
$menu[] = array("type"=>"FeatureCollection",
"features" => [array("type"=>"Feature",
"geometry"=>array("type"=>"Point",
"coordinates"=>[-77.034084142948,38.909671288923]),
"properties"=>array("phone"=>"041","city"=>"Faisalabad","country"=>"Pakistan"))]
);
} $json = json_encode($menu);
echo $json;
and the result looks like this:
[
{
"type": "FeatureCollection",
"features": [
{
"type": "Feature",
"geometry": {
"type": "Point",
"coordinates": [
-77.034084142948,
38.909671288923
]
},
"properties": {
"phone": "041",
"city": "Faisalabad",
"country": "Pakistan"
}
}
]
},
{
"type": "FeatureCollection",
"features": [
{
"type": "Feature",
"geometry": {
"type": "Point",
"coordinates": [
-77.034084142948,
38.909671288923
]
},
"properties": {
"phone": "041",
"city": "Faisalabad",
"country": "Pakistan"
}
}
]
},
{
"type": "FeatureCollection",
"features": [
{
"type": "Feature",
"geometry": {
"type": "Point",
"coordinates": [
-77.034084142948,
38.909671288923
]
},
"properties": {
"phone": "041",
"city": "Faisalabad",
"country": "Pakistan"
}
}
]
}]
As you can see {"type": "FeatureCollection","features":[{...}]}is being repeated three time, I want it to appear at the beginning only like following json, so that {"type": "FeatureCollection","features":[{I WANT LOOP HERE only}]}: I want this result:
[
{
"type": "FeatureCollection",
"features": [
{
"type": "Feature",
"geometry": {
"type": "Point",
"coordinates": [
-77.034084142948,
38.909671288923
]
},
"properties": {
"phone": "041",
"city": "Faisalabad",
"country": "Pakistan"
}
},
{
"type": "Feature",
"geometry": {
"type": "Point",
"coordinates": [
-77.034084142948,
38.909671288923
]
},
"properties": {
"phone": "041",
"city": "Faisalabad",
"country": "Pakistan"
}
},
{
"type": "Feature",
"geometry": {
"type": "Point",
"coordinates": [
-77.034084142948,
38.909671288923
]
},
"properties": {
"phone": "041",
"city": "Faisalabad",
"country": "Pakistan"
}
}
]
}]
Please help I have been trying too much. Thanks

Answer 1

Well, why do you keep repeating "FeatureCollection" in the while-loop if you only want it once?
I think you want something like this:
$menu = array();
features = array();
$menu['type'] = 'FeatureCollection';
while ($row = mysql_fetch_array($result)) {
$features[] = array("type"=>"Feature",
//Other features here
);
}
$menu['features'] = $features;

Answer 2

In your $menu array you shoud define key type with value FeatureCollection, and key features. And in your while loop do this:
$menu = array(
'type' => 'FeatureCollection',
'features' => array()
);
while ($row = mysql_fetch_array($result)) {
$menu[`features`][] = array(...);
}
