I am trying to get all twitter followers for a specific user with this API call
https://api.twitter.com/1/users/lookup.json?screen_name=twitterapi,twitter&include_entities=true
And there is a sample output there:
https://dev.twitter.com/docs/api/1/get/users/lookup
I am trying to get the screen name of the user by doing the following:
$json2=file_get_contents('http://api.twitter.com/1/users/lookup.json?user_id='.$post.'') ;
$accounts2 = json_decode($json2);
while( $element = each( $accounts2 ) ) {
echo $element[ 'screen_name' ];
echo '<br />';
}
where $post is all the ids (around 100) concatenated together.
The above would fail with:
Notice: Trying to get property of non-object
Any help please?
Replace this line:
$accounts2 = json_decode($json2);
With this:
$accounts2 = json_decode($json2, true);
It converts it into an associative array. Because user_id is unique, you don't have to loop through the results, but can simply do this:
echo $accounts2[0]['screen_name'] . '<br />';
This worked.
$json2=file_get_contents('http://api.twitter.com/1/users/lookup.json?user_id='.$post.'') ;
$accounts2 = json_decode($json2);
foreach ($accounts2 as $key => $jsons) {
foreach($jsons as $key => $value) {
if($key == 'screen_name'){
echo $value;
}
}
}
Use this.
$json2=file_get_contents('http://api.twitter.com/1/users/lookup.json?user_id='.$post.'') ;
$accounts2 = json_decode($json2,true);
echo $accounts2[0]['screen_name'];

Hello everyone,
This is my array and I want to echo value of only "id" i.e. I want to get value as '115' of key- "id". Please guide me how to make a foreach for this one? I have tried lots of variations but none worked :(
TIA :)
UPDATE-
I have tried this but did not get any result:
foreach($res as $k=>$t)
{
echo $t["product_details"]["id"];
}
Before you can use the JSON as an array you need to convert it first. use json_decode() for that.
<?php
$json='{"2b44928ae11fb9384c4cf38708677c48":{"id":"115","qty":3,"option":"{\"color\":{\"title\":\"Color\",\"value\":\"\"}}","price":150,"name":"Nightwear","shipping":"5","tax":3,"image":"http:\/\/localhost\/plus\/uploads\/product_image\/product_115_1_thumb.jpg","coupon":"","rowid":"2b44928ae11fb9384c4cf38708677c48","subtotal":450}}';
$array = json_decode($json, true);
foreach($array as $key=>$value){
echo $value['id'];
}
?>
Assuming you have an array of objects like you provided in your post, I have put your object in an array for testing
<?php
$json = '[{"2b44928ae11fb9384c4cf38708677c48":{"id":"115","qty":3,"option":"{\"color\":{\"title\":\"Color\",\"value\":\"\"}}","price":150,"name":"Nightwear","shipping":"5","tax":3,"image":"http:\/\/localhost\/plus\/uploads\/product_image\/product_115_1_thumb.jpg","coupon":"","rowid":"2b44928ae11fb9384c4cf38708677c48","subtotal":450}},'.
'{"2b44928ae11fb9384c4cf38708677c48":{"id":"116","qty":3,"option":"{\"color\":{\"title\":\"Color\",\"value\":\"\"}}","price":150,"name":"Nightwear","shipping":"5","tax":3,"image":"http:\/\/localhost\/plus\/uploads\/product_image\/product_115_1_thumb.jpg","coupon":"","rowid":"2b44928ae11fb9384c4cf38708677c48","subtotal":450}}]';
$json = json_decode($json);
foreach ($json as $object){
$propsArray = get_object_vars($object);
reset($propsArray);
echo $object->{key($propsArray)}->id . "<br>\n";
}
exit;
this outputs
115
116
try a live demo (https://eval.in/836364)

$array = json_decode($json, true); // convert json string to array
$result = array_column($array, 'id'); // find matching array key and return values in array
foreach ($result as $value) { // echo each value with foreach loop
echo $id . '<br>';
}
I want to find index of key from json array similar to this question Get index of a key in json
but i need the solution using php.
here is my json (partial data)
{
"currentOver":{
"events":[]
},
"matchString":"",
"currentPlayer":5,
"previousOvers":[],
"innings":[],
"scorecards":[
{
"batting":{
"players":[
{"id":16447,"name":"Rahul Roy"},
{"id":12633,"name":"Sijal Thomas"},
{"id":16446,"name":"Mohammed Reza"},
{"id":16509,"name":"Asif Khan"},
{"id":12633,"name":"Koyel Dijesh"},
{"id":16468,"name":"Shahrook"},
{"id":64691,"name":"Shafiq"},
{"id":6518,"name":"Ubaidulah"}
]
}
}
]
}
and php
foreach ($read_json->scorecards->batting->players as $batsmen => $val) {
if($val == 5) { // if batsman index is 5 then display his name
$name = $batsmen->name;
echo "<div>$name</div>\n";
}
}
Please help me to solve this issue.Thanks in advance.
I think this would suffice your requirement
http://codepad.org/XQDCKAsB
Find the code sample below as well.
$json = '{"currentOver":{"events": []},"matchString":"","currentPlayer":5,"previousOvers":[],"innings":[],"scorecards":[{"batting":{"players":[{"id":16447,"name":"Rahul Roy"},{"id":12633,"name":"Sijal Thomas"},{"id":16446,"name":"Mohammed Reza"},{"id":16509,"name":"Asif Khan"},{"id":12633,"name":"Koyel Dijesh"},{"id":16468,"name":"Shahrook"},{"id":64691,"name":"Shafiq"},{"id":6518,"name":"Ubaidulah"}]}}]}';
$arr = json_decode($json);
echo '<pre>';
$currentPlayer = $arr->currentPlayer;
echo $arr->scorecards[0]->batting->players[$currentPlayer-1]->name;
Try this code.
$info = json_decode('json string');
$currentPlayer = $info->currentPlayer;
$batsman = $info->scorecards[0]->batting->players[$currentPlayer];
echo "<div>{$batsman->name}</div>\n";
Also, note that arrays in PHP are zero-based. If currentPlayer index in json data is based on 1 (rare case, but it exists sometimes) you will ned to use
$batsman = $info->scorecards[0]->batting->players[$currentPlayer - 1];
to get right item from array.
If you just want to fix your foreach
$read_json->scorecards->batting should become $read_json->scorecards[0]->batting
if($val == 5) should become if($batsmen == 5)
$name = $batsmen->name; should become $name = $val->name;
You need to use json_decode and array_keys for the array keys from the json.
$json = '{ "key1" : "watevr1", "key2" : "watevr2", "key3" : "watevr3" }';
$result = json_decode ($json, true);
$keys = array_keys($result);
print_r($keys); //Array ( [0] => key1 [1] => key2 [2] => key3 )
In Php, You can use the code below, if you wan to fix it using foreach loop
foreach($json->entries as $row)
{
foreach($row as $key => $val)
{
echo $key . ': ' . $val;
echo '<br>';
}
}
please have a look following code
$json=json_decode($data)->scorecards[0]->batting->players;
foreach ($json as $key => $value) {
if($key==5){
echo $value->name ;
}
}
You can do it using converting JSON string to Array
$json_str = '{
"currentOver":{
"events":[]
},
"matchString":"",
"currentPlayer":5,
"previousOvers":[],
"innings":[],
"scorecards":[
{
"batting":{
"players":[
{"id":16447,"name":"Rahul Roy"},
{"id":12633,"name":"Sijal Thomas"},
{"id":16446,"name":"Mohammed Reza"},
{"id":16509,"name":"Asif Khan"},
{"id":12633,"name":"Koyel Dijesh"},
{"id":16468,"name":"Shahrook"},
{"id":64691,"name":"Shafiq"},
{"id":6518,"name":"Ubaidulah"}
]
}
}
]
}';
Decode your JSON string using "json_decode" and you get array
$json_decode_str = json_decode($json_str, true);
Now using foreach you can do anything
if($json_decode_str['scorecards']){
foreach($json_decode_str['scorecards'] as $scorecard){
$player_index = 1;
if($scorecard['batting']['players']){
foreach($scorecard['batting']['players'] as $player){
if($player_index == 5){
echo $player['name'];
}
$player_index++;
}
}
}
}
Maybe this one help you :)
i can loop through 2 elements in an array , but here im having trouble looping through 3 elements .
this is my example :
$y = array('cod=>102,subcod=>10201,name=>"blabla"',
'cod=>103,subcod=>10202,name=>"blibli"',
'cod=>103,subcod=>10202,name=>"bblubl"')
my desire result is how to get the value of cod and subcod and name of every line .
I tried this :
foreach ($y as $v) {
echo $v['cod'] ;
echo $v['subcod'];
echo $v['name'] ;
}
but didnt work , im getting this error : Warning: Illegal string offset 'cod' and same error for every offset .
any help would be much apreciated.
If you can't change you're array
Then you need to format that and then use the loop and get the value.
function format_my_array($arg) {
$new = array();
foreach( $arg as $n => $v ) {
// splitting string like
// 'cod=>102,subcod=>10201,name=>"blabla"'
// by comma
$parts = explode(',', $v);
$new[$n] = array();
foreach( $parts as $p ) {
// splittin again by '=>' to get key/value pair
$p = explode('=>', trim($p));
$new[$n][$p[0]] = $p[1];
}
}
return $new;
}
$new_y = format_my_array($y);
foreach( $new_y as $v ) {
echo $v['cod'];
echo $v['subcod'];
echo $v['name'];
}
I am having a array like so and I am looping trough it like this:
$options = array();
$options[0] = 'test1';
$options[1] = 'test2';
$options[2] = 'test3';
foreach($options as $x)
{
echo "Value=" . $x ;
echo "<br>";
}
It outputs as expected:
Value=test
Value=test2
Value=test3
Now I want to add some options to my array and loop trough them:
$options = array();
$options['first_option'] = 'test';
$options['second_option'] = get_option('second_option');
$options['third_option'] = get_option('third_option');
foreach($options as $x)
{
echo "Value=" . $x ;
echo "<br>";
}
But it does not work as I want. Because it outputs:
Value=first_option
Value=second_option
Value=third_option
So now I do not know how to access stored values using foreach from these guys?
Something like:
Value=first_option='test'
So when I use print_r($options)
Output is:
Array
(
[first_options] => test
[second_option] =>
[third_option] =>
)
1
your loop should look like this:
foreach($options as $key => $val){
echo "Val: ".$val;
echo "<br/>";
}
Your code is working just as expected and producing the desired result. You must have something else changing the values in $options. Correction: now that I see your edit, your functions are not returning any values, so options 1 and 2 are blank. Make sure that function returns something. Other than that, all of this code is good.
By the way, I recommend this:
$options = [
'first_option' => 'test',
'second_option' => get_option('second_option'),
'third_option' => get_option('third_option')
];
foreach($options as $key) {
echo "Value = {$key}<br>";
}
you can also use:
foreach($options as $key => $value) {
echo "Value - {$value} = {$key}<br>";
}
or you could at least replace array() with just []. Those are just some suggestions for neatness.
I have this array:
$json = json_decode('
{"entries":[
{"id": "29","name":"John", "age":"36"},
{"id": "30","name":"Jack", "age":"23"}
]}
');
and I am looking for a PHP "for each" loop that would retrieve the key names under entries, i.e.:
id
name
age
How can I do this?
Try it
foreach($json->entries as $row) {
foreach($row as $key => $val) {
echo $key . ': ' . $val;
echo '<br>';
}
}
In the $key you shall get the key names and in the val you shal get the values
You could do something like this:
foreach($json->entries as $record){
echo $record->id;
echo $record->name;
echo $record->age;
}
If you pass true as the value for the second parameter in the json_decode function, you'll be able to use the decoded value as an array.
I was not satisfied with other answers so I add my own. I believe the most general approach is:
$array = get_object_vars($json->entries[0]);
foreach($array as $key => $value) {
echo $key . "<br>";
}
where I used entries[0] because you assume that all the elements of the entries array have the same keys.
Have a look at the official documentation for key: http://php.net/manual/en/function.key.php
You could try getting the properties of the object using get_object_vars:
$keys = array();
foreach($json->entries as $entry)
$keys += array_keys(get_object_vars($entry));
print_r($keys);
foreach($json->entries[0] AS $key => $name) {
echo $key;
}
$column_name =[];
foreach($data as $i){
foreach($i as $key => $i){
array_push($column_name, $key);
}
break;
}
Alternative answer using arrays rather than objects - passing true to json_decode will return an array.
$json = '{"entries":[{"id": "29","name":"John", "age":"36"},{"id": "30","name":"Jack", "age":"23"}]}';
$data = json_decode($json, true);
$entries = $data['entries'];
foreach ($entries as $entry) {
$id = $entry['id'];
$name = $entry['name'];
$age = $entry['age'];
printf('%s (ID %d) is %d years old'.PHP_EOL, $name, $id, $age);
}
