How to access array inside document using PHP [duplicate] - php

Get data from JSON file with PHP [duplicate]

Closed 6 years ago.
I want print specific vars from array inside a document.
JSON structure:
{
"return": {
"string": "2222",
"contacts": [
{
"contact": {
"id": "09890423890"
}
},
{
"contact": {
"id": "2423444"
}
},
{
"contact": {
"id": "24242423"
}
},
etc
]
}
}
I am trying to do this in PHP (and already decoded that json). How can I access and print all ids using foreach or for?
I can not understand how I can manage "return" scope.

Answer 1

You can decode the json contents and use it like an array. This should work:
$json = json_decode($string, true);
$contacts = $json['return']['contacts'];
foreach($contacts as $contact){
echo $contact['contact']['id'];
}

Answer 2

Json decode to array:
$json = json_decode($strjson, true); // decode the JSON into an associative array
and
echo "<pre>";
print_r($json);
And foreach:
foreach ($json as $key => $value) {
echo $key . " ". $value. "<br>";
}
Working example:
$json = '{
"return": {
"string": "2222",
"contacts": [
{
"contact": {
"id": "09890423890"
}
},
{
"contact": {
"id": "2423444"
}
},
{
"contact": {
"id": "24242423"
}
}
]
}
}';
$json = json_decode($json, true);
print_r($json);
foreach ($json['return']['contacts'] as $val) {
echo $val['contact']['id']."<br>";
}

Answer 3

Try this code:
$json ='
{
"return": {
"string": "2222",
"contacts": [
{
"contact": {
"id": "09890423890"
}
},
{
"contact": {
"id": "2423444"
}
},
{
"contact": {
"id": "24242423"
}
},
etc
]
}
}
';
$array = json_decode($json,TRUE);
foreach($array['return']['contacts'] as $value ){
echo $value['id'];
}
Use file_get_contents function if you want to pull data from file.
