Here's my PHP code:
<?php
$json_url = "REDACTED";
$json = file_get_contents($json_url);
$stats = json_decode($json, true);
foreach ($stats as $row) {
echo $row['results']['result']['conversions'] . "<br />";
}
?>
Here's the JSON:
{
"metadata":{
"iserror":"false",
"responsetime":"0.07s"
},
"results":{
"first":1,
"last":99,
"total":99,
"result":[
{
"total_visitors":"3",
"visitors":"3",
"conversions":"0"
},
{
"total_visitors":"26",
"visitors":"26",
"conversions":"0"
},
{
"total_visitors":"13",
"visitors":"13",
"conversions":"0"
},
{
"total_visitors":"1",
"visitors":"1",
"conversions":"0"
},
{
"total_visitors":"1",
"visitors":"1",
"conversions":"0"
}
]
}
}
Essentially I'm just trying to echo the "conversions" from each section in the json file.
Never worked with a JSON file using PHP for, so I'm not really sure where I'm going wrong with this.
Need small correction in accessing array like below
foreach ($stats['results']['result'] as $row) {
echo $row['conversions'] . "<br />";
}
Because when you do json_decode, you will get array like below
Array
(
[metadata] => Array
(
[iserror] => false
[responsetime] => 0.07s
)
[results] => Array
(
[first] => 1
[last] => 99
[total] => 99
[result] => Array
(
[0] => Array
(
[total_visitors] => 3
[visitors] => 3
[conversions] => 0
)
[1] => Array
(
[total_visitors] => 26
[visitors] => 26
[conversions] => 0
)
[2] => Array
(
[total_visitors] => 13
[visitors] => 13
[conversions] => 0
)
[3] => Array
(
[total_visitors] => 1
[visitors] => 1
[conversions] => 0
)
[4] => Array
(
[total_visitors] => 1
[visitors] => 1
[conversions] => 0
)
)
)
)
It should be like following:
<?php
$json_url = "REDACTED";
$json = file_get_contents($json_url);
$stats = json_decode($json, true);
if ($stats && isset($stats['results']) && isset($stats['results']['result'])) {
foreach ($stats['results']['result'] as $row) {
echo $row['conversions'] . "<br />";
}
}
?>
So check if needed fields are set in JSON, and then loop for every result record to get the conversions.
$stats = json_decode($json, true);
foreach ($stats['results']['result'] as $row) {
echo $row['conversions'] . "<br />";
}

I have JSON data and want to update the value by key.
JSON:
{
"language":"en",
"education":[
{
"unit":"e1",
"language":"en"
}
],
"membership":[
{
"uei":"21",
"Uifed":"failed"
}
]
}
I want to change the value of uifed from "failed" to "success".
What have I done?
$json = '{"language":"en","education":[{"unit":"e1","language":"en"}],"membership":[{"uei":"21","Uifed":"failed"}]}';
$arrayData = json_decode($json, true);
$replacementData = array('Uifed' => 'success');
$newArrayData = array_replace_recursive($arrayData, $replacementData);
echo var_dump($newArrayData);
Result:
NULL
How can I do that?
That's not how array_replace_recursive works; the replacement arrays need to have the same structure as the one you are replacing into. For your sample data, this will work:
$json = '{"language":"en","education":[{"unit":"e1","language":"en"}],"membership":[{"uei":"21","Uifed":"failed"}]}';
$arrayData = json_decode($json, true);
$replacementData = array('membership' => array(array('Uifed' => 'success')));
$newArrayData = array_replace_recursive($arrayData, $replacementData);
print_r($newArrayData);
Output:
Array
(
[language] => en
[education] => Array
(
[0] => Array
(
[unit] => e1
[language] => en
)
)
[membership] => Array
(
[0] => Array
(
[uei] => 21
[Uifed] => success
)
)
)
array_walk_recursive can be used to do what you want:
$replacementData = array('Uifed' => 'success');
array_walk_recursive($arrayData, function (&$value, $key) use ($replacementData) {
$value = $replacementData[$key] ?? $value;
});
print_r($arrayData);
Output:
Array
(
[language] => en
[education] => Array
(
[0] => Array
(
[unit] => e1
[language] => en
)
)
[membership] => Array
(
[0] => Array
(
[uei] => 21
[Uifed] => success
)
)
)
Demo on 3v4l.org
Simple example with foreach and passing values by reference:
$json = '{"language":"en","education":[{"unit":"e1","language":"en"}],"membership":[{"uei":"21","Uifed":"failed"}]}';
$arrayData = json_decode($json, true);
foreach ($arrayData['membership'] as &$membership) {
if ('failed' === $membership['Uifed']) {
$membership['Uifed'] = 'success';
}
}
print_r($arrayData);
Fiddle.
I am parsing A JSON file in PHP using PHP Decode
$json= file_get_contents ("resultate.json");
$json = json_decode($json, true);
and then I am trying to loop through the results and display them
foreach($json as $zh){
$name = $zh[0]["VORLAGEN"][0]["JA_PROZENT"];
$JA = $zh[0]["VORLAGEN"][0]["VORLAGE_NAME"];
$kreis = $zh[0]["NAME"];
$kreis1 = $zh[22]["NAME"];
echo $name;
echo $JA;
echo $kreis;
echo $kreis1;
...}
but I receive only one element e.g. position 0 or position 22. I would like to receive all the results and display them in a list. Below you can see the array
Array

can you please tell me how to print all the elements of this array?
There is GEBIETE layer in your json, so change foreach($json as $zh) to foreach($json["GEBIETE"] as $zh) will works.
You can nest multiple foreach:
$root = $json['GEBIETE'];
foreach ($root as $elem) {
foreach ($elem as $key => $value) {
// VORLAGEN is an array of its own so if you want to print the keys you should foreach this value as well
if(is_array($value)) {
foreach ($value[0] as $k => $v) {
echo $k."\t".$v;
}
}
else {
echo $value;
}
}
}
I have array something like this
Array
(
[0] => Array
(
[product_id] => 13
[unit] => 1
[price] => 20.0000
[total] => 20.0000
)
[1] => Array
(
[product_id] => 15
[unit] => 2
[price] => 30.0000
[total] => 10.0000
)
)
I was stuck to transform above array to the "ProductList" in the following pattern
array(
"UserID" => 2,
"ProductList" => [
{
"ProductID"=> 13,
"Price"=> 20.0000
},
{
"ProductID"=> 15,
"Price"=> 30.0000
}
]
)
I tried like this:
$products = [];
foreach($items as $item) {
if(!empty($item['product_id'])) {
$product = '{"ProductID"=>' . $item['product_id'] . '}';
$products[] = $product;
}
}
But not the expected result.
You're looking for json_encode(): http://php.net/manual/en/function.json-encode.php
Assign your array to a variable, for example $products, and then you can simply write json_encode($products) to achieve your desired result.
Try this,
$prodlist = array();
$x = 0;
foreach($arrs as $arr) {
//if ($arr['product_id'] == "" && $arr['price'] == "") continue;
$prodlist[$x]['Price'] = $arr['price'];
$prodlist[$x]['ProductID'] = $arr['product_id'];
$x += 1;
}
$arr2return['user_id'] = $user_id;
$arr2return['ProductList'] = $prodlist;
json_encode($arr2return);
Hi everyone I have a json named rushlist.json using this format:
{"rushlist":[{"Char":"Whipthemout","Pass":1,"Fail":1,"Status":"Free"}]}
I figured out how to display the whole array with this:
<?php
$Rushlist = json_decode(file_get_contents("rushlist.json"), true);
print_r($Rushlist);
?>
It displays :
Array ( [rushlist] => Array ( [0] => Array ( [Char] => Whipthemout [Pass] => 1 [Fail] => 1 [Status] => Free ) ) )
However I want to display just the element/value not this:
Array ( [rushlist] => Array ( [0] => Array ( [Char] => Whipthemout [Pass] => 1 [Fail] => 1 [Status] => Free ) ) )
Something like this
Rushlist
[Char] = Whipthemout
[Pass] = 1
[Fail] = 1
[Status] = Free
Any help would be great!
Thanks.
EDIT
<?php
$Rushlist = json_decode(file_get_contents("rushlist.json"), true);
print_r($Rushlist);
foreach($Rushlist as $arr_name=>$arr) {
print $arr_name . "\n";
foreach($arr as $key=>$value) {
print "[" . $key . "] = " . $value . "\n";
}
}
?>
Displays this:
Array ( [rushlist] => Array ( [0] => Array ( [Char] => Whipthemout [Pass] => 1 [Fail] => 1 [Status] => Free ) ) ) rushlist
Notice: Array to string conversion in F:\Share\test\Dropbox\test\test3.php on line 9
[0] = Array
foreach($Rushlist as $arr_name=>$arr) {
print $arr_name . "\n";
foreach($arr as $arr2 ) {
foreach($arr2 as $key=>$value) {
print "[" . $key . "] = " . $value . "\n";
}
}
}
That should do it.
UPDATED
I have this JSON-File here
{
"id" : "bf75b277-169b-49da-8ab1-b78b8dfg1b43-e25c7f28b3",
"ts" : "1372751172664",
"connected" : {
"ssid" : "eduroam",
"bssid" : "00:0f:f9:eb:08:81",
"rssi" : "-62",
"speed" : "53"
},
"configured" : [
{
"ssid" : "eduroam",
"bssid" : "null",
"keyMgmnt" : ["2", "3"],
"grCiphers" : ["0","1","2","3"]
},
{
"ssid" : "foobar",
"bssid" : "null",
"keyMgmnt" : ["0"],
"grCiphers" : ["0","1","2","3"]
}
],
"location" : {
"prov" : "network",
"lat" : "52.3793203",
"lon" : "9.7231332",
"acc" : "22.777"
}
}
and I'm trying to get the key-value-pairs out into a file (and later into a mysql-database).
I am having trouble to go along the nested structure. Maybe I do not understand it correctly?
$LOGPATH = "/var/www/test/";
$out = fopen($LOGPATH."testlog.log", "a");
$result = file_get_contents('php://input');
$data = json_decode($result, true);
$value = $data;
$test = array();
This line beneath causes me headaches, how can I say get the key-value-pairs of "connected"?
Trying $test = $data['connected'] did not work, as the output simply is a "{" and nothing more...
$test = $data;
fwrite($out, "test \n");
fwrite($out, $test);
fwrite($out, "\n");
foreach ($test as $entry){
fwrite($out, $entry);
fwrite($out, "\n");
}
Any idea how to extract the key-value-pairs and/or help me understand the structure?
This should get you on the right track
foreach($data['connected'] as $key => $value){
echo 'Key: '.$key.' Value:'.$value.'<br>';
}
json_decode() will dump JSON into regular array. You can do print_r() or var_dump() on it, to see the structure of the array. So to get your connected leaf you do:
$connected = $data['connected'];
You can then iterate over it:
foreach( $connected as $key=>$val ) {
echo $key . ": " . $val;
}
Got it, thanks to you guys!
// Get a request from i.e. a webpage (this is a webservice)
$jsonArray = file_get_contents('php://input');
// put the JSON-Data into an array
$jsonData = json_decode($jsonArray, true);
// You can simply choose the entry-points. As they do not change for me, they are hardcoded in here, else you had to use something like a for-loop to extract them
$jsonConnect = $jsonData['connected'];
$jsonLocation = $jsonData['location'];
$jsonConfigured = $jsonData['configured'];
// walk through the JSON-Data and extract the values, although the array has more than 2 levels, you can select your entry-point and walk from there on, which makes this quite easy
for($i = 0; $i < count($jsonConfigured); $i++){
// keyMgmnt itself is an array and I want to concatenate all of its values and put it into a single field in my MySQL-DB, so implode() is used
$keyMgmnt = implode(",", $jsonConfigured[$i]['keyMgmnt']);
$grCiphers = implode(",", $jsonConfigured[$i]['grCiphers']);
$ssid = $jsonConfigured[$i]['ssid'];
$bssid = $jsonConfigured[$i]['bssid'];
// from here on I simply put the variables into my MySQL-DB
$sql_configured = "INSERT INTO configured (keyMgmnt, grCiphers, ssid, bssid) VALUES ('$keyMgmnt', '$grCiphers', '$ssid', '$bssid')";
mysql_query($sql_configured) or die ("Failure in configured");
}
$sql_connected = "INSERT INTO connected (rssi, speed, ssid, bssid) VALUES ('$jsonConnect[rssi]', '$jsonConnect[speed]', '$jsonConnect[ssid]', '$jsonConnect[bssid]')";
$enterConnected = mysql_query($sql_connected) or die("Failure in connection!");
$sql_location = "INSERT INTO location (lat, prov, lon, acc) VALUES ('$jsonLocation[lat]', '$jsonLocation[prov]', '$jsonLocation[lon]', '$jsonLocation[acc]')";
$enterLocation = mysql_query($sql_location) or die("Failure in location!");
Thanks again!
Case closed.
PS: The structure of the JSON-Data. You get it by using "print_r()" or "var_dump()".
