this is my contoller
$pid = json_decode(file_get_contents('php://input'), true);
foreach ($pid as $key => $value) {
foreach ($value as $keys => $values) {
$c_res = $this->Model_master->get_sup($values);
echo json_encode($c_res, 200);
}
}
this is my model
$q = $this->db->select('contact_number')->from('shopxie_people')
->where("p_id = ".$value)
->get();
return $q->result_array();
this shows me result in html form but when i change it to json it gives me
SYntax error
also in postman content-type is showing as text/html;
why does it happen even after encoding in json in my code?
Hope this will help you :
Do something like this in your controller :
foreach ($pid as $key => $value)
{
foreach ($value as $keys => $values)
{
$c_res[] = $this->Model_master->get_sup($values);
}
}
echo json_encode($c_res);
exit;

I am decoding the array of json objects into html lists . i have tried with some demo it worked but when i deal with this array of json this gives error as : Invalid argument supplied for foreach(). what is i am missing ?
<?php

$array = json_decode($json_string, true);
function build_list($array) {
$list = '<ul>';
foreach($array as $key => $value) {
foreach($value as $key => $index) {
if(is_array($index)) {
$list .= build_list($index);
} else {
$list .= "<li>$index</li>";
}
}
}
$list .= '</ul>';
return $list;
}
echo build_list($array);
?>
Simply use only one foreach, the nested one seems useless :
foreach($array as $key => $index) {
if(is_array($index)) {
/* ... */
Just add a condition to check if $value is a valid array or not. This way it will not process $value if it's not an array and warnings will go away.
if (!is_array($value)) {
continue;
}
Use this condition inside foreach before the looping $array.
foreach($array as $key => $value) {
if (!is_array($value)) {
continue;
}
foreach($value as $k => $index) {
if(is_array($index)) {
$list .= build_list($index);
} else {
$list .= "<li>$index</li>";
}
}
}

I'm trying to parse JSON data in the format [{code:SE rate:1.294},{code:UK rate:2.353}] from this page:
http://www.mycurrency.net/service/rates
I have implemented an IP reader that detects the users location in a 2 letter country code. I want to pluck the correct data from that link with 'code' and return the value 'rate'. I was thinking I might have to do a foreach loop to iterate through all the countries?
This is my code, I hope this is what are you looking for.
First I create a new array $output to make it more easy to search
$string = file_get_contents("http://www.mycurrency.net/service/rates");
$json = json_decode($string, true);
foreach ($json as $key => $data) {
$output[$key]['code'] = $data['code'];
$output[$key]['rate'] = $data['rate'];
}
After that we use a function to search value in array and returning the key. I got it from here
function searchForRate($countryCode, $array) {
foreach ($array as $key => $val) {
if ($val['code'] === $countryCode) {
return $key;
}
}
return null;
}
and then I run the function with the first parameter as country code to get the keys of specific country code.
$find = searchForRate("BT", $output);
And then echo the rates from our $output array by key in $find variable
echo 'RATE = '.$output[$find]['rate'];
This is the complete codes
<?php
$string = file_get_contents("http://www.mycurrency.net/service/rates");
$json = json_decode($string, true);
foreach ($json as $key => $data) {
$output[$key]['code'] = $data['code'];
$output[$key]['rate'] = $data['rate'];
}
function searchForRate($countryCode, $array) {
foreach ($array as $key => $val) {
if ($val['code'] === $countryCode) {
return $key;
}
}
return null;
}
$find = searchForRate("BT", $output);
echo 'RATE = '.$output[$find]['rate'];
Example output:
RATE = 64.13
So here's the thing, I get this json from a url ( in my context i get it from a url, but let's say here I write my json in a variable :
$file = '[
{"status": "5.4.1","email": "dddddd#exelcia-it.com"},
{"status": "5.4.1",, "email": "sksksksk#exelcia-it.com"}
]'
Then I do $json = json_decode($file,true);
And I want to get all the emails so I do :
foreach ($json as $key => $value) {
echo $value["email"]. "<br>";
}
But what I also need, is to return something like that from the loop (only for one property):
"email = dddddd#exelcia-it.com".
So I need to also get the name of the property but I can't figure this out.
I tried
foreach($json as $key => $propName){
echo $key.'<br>';
}
But I just get the index (0,1,...), not what I want.
Thanks!
You have to loop each json row, this should works:
$file = '[{"status": "5.4.1","email": "dddddd#exelcia-it.com"},{"status": "5.4.1", "email": "sksksksk#exelcia-it.com"}]';
$json = json_decode($file,true);
foreach($json as $row)
{
foreach($row as $key => $value)
{
echo "<b>".$key."</b>".':'.$value.'<br>';
}
}
Use this loop to get key and value pairs together.
foreach($data as $row)
{
foreach($row as $key => $val)
{
echo $key . ': ' . $val;
echo '<br>';
}
}
Ok thanks that's what I needed !
For me I just need the email properties and values, so I do :
foreach($json as $row)
{
foreach($row as $key => $value)
{
if($key=='email'){
echo "<b>".$key."</b>".':'.$value.'<br>';
}
}
}
Awesome ! thanks !
I have the following error in the code below.
Warning: Invalid argument supplied for foreach() in
/admin/controller/module/megamenu.php on line 263 The list was updated
15-05-27 23:25:14!
Line 263 : foreach ($jsonArray as $subArray) {
I checked on another server and does not appear this error (php5.4) but my server with php5.3, php5.5 appear. What's missing?
if (isset($_GET['jsonstring'])) {
if($this->validate()){
$jsonstring = $_GET['jsonstring'];
$jsonDecoded = json_decode(html_entity_decode($jsonstring));
function parseJsonArray($jsonArray, $parentID = 0) {
$return = array();
foreach ($jsonArray as $subArray) {
$returnSubSubArray = array();
if (isset($subArray->children)) {
$returnSubSubArray = parseJsonArray($subArray->children, $subArray->id);
}
$return[] = array('id' => $subArray->id, 'parentID' => $parentID);
$return = array_merge($return, $returnSubSubArray);
}
return $return;
}
$readbleArray = parseJsonArray($jsonDecoded);
foreach ($readbleArray as $key => $value) {
if (is_array($value)) {
$this->model_menu_megamenu->save_rang($value['parentID'], $value['id'], $key, $data['active_module_id']);
}
}
die("The list was updated ".date("y-m-d H:i:s")."!");
} else {
die($this->language->get('error_permission'));
}
}
Change
$jsonDecoded = json_decode(html_entity_decode($jsonstring));
to
$jsonDecoded = json_decode(html_entity_decode($jsonstring),true);
and $jsonDecoded will be an array
i think i some cases we have to use implode and explode functions when we work with json data in php, try this after decoding your json data to convert an string to an array.
Can anyone tell me whats wrong with this code?
<?php
$feedID = '28241415';
$oddsArray = array();
$source = file_get_contents("https://www.bwin.com/partner/xml/query.aspx?source=events&lid=1&xpath=/ROOT/EVENTS/E[#LID=46%20and%20#RID=14%20and%20#SID=4]");
$xml = simplexml_load_string($source);
$game = $xml->xpath("//G");
foreach ($game as $event)
{
if ($event['DBID'] == $feedID)
{
foreach ($event->children() as $odds)
{
array_push($oddsArray, array('oddsID' => $odds['DBID'], 'odds' => $odds['O']));
}
}
}
foreach ($array as $oddsArray)
{
echo $array['odds'];
echo $array['oddsID'];
}
?>
The error I am receiving is:
Warning: Invalid argument supplied for foreach() in /home/pokerint/public_html/test.php on line
I am guessing here as the question isn't quite clear but I think you need to reverse the order of your variables in your last foreach from
foreach ($array as $oddsArray)
{
echo $array['odds'];
echo $array['oddsID'];
}
To
foreach ($oddsArray as $array)
{
echo $array['odds'];
echo $array['oddsID'];
}
foreach ($array as $oddsArray)
I think you have this backwards ...
To avoid confusion , I always use something easy to remember ...
foreach ($oddsArray as $key => $value) {
OR
foreach ($oddsArray as $value) {
even ...
then you will never get mixed up (well hopefully never :)
