php using file_get_contents with an array - php

I am trying to pull values from the following url: https://api.binance.com/api/v1/ticker/allPrices
What I want to accomplish:
Obtain all the "symbol" values printed in the website (one under the other)
The result I am looking for, would be:
ETHBTC
LTCBTC
...
This is what I have done so far:
<?php
$url = "https://api.binance.com/api/v1/ticker/allPrices";
$content = file_get_contents($url);
$json_data = json_decode($content, true);
for ($i=0; $i < count($json_data); $i++) {
# code...
print_r($json_data);
}
?>
The result it brings is the entire data (the symbols, prices, plus other irrelevant data).
Thanks in advance.


You can use foreach loop, then echo the value by symbol key
$url = "https://api.binance.com/api/v1/ticker/allPrices";
$content = file_get_contents($url);
$json_data = json_decode($content, true);
foreach ($json_data as $value) {
echo $value["symbol"] . '<br>';
}


This ought to do it:
<?php
$url = "https://api.binance.com/api/v1/ticker/allPrices";
$content = file_get_contents($url);
$json_data = json_decode($content, true);
for ($i=0; $i < count($json_data); $i++) {
echo $json_data[$i]['symbol'] . "\n";
}
?>


json_data["symbol"]
instead in the print

PHP Wont print from external API

I use to go to school for only a short time in programming. A while ago and I'm rusty. I've been trying to re-learn everything by myself and something is bothering me. I'm trying to print out a specific object from an external API but nothing I try seems to work out. I don't really know what to google to get the right answer I am looking for. Anyway here's my code.
<?php
$url = 'http://apis.is/flight?language=en&type=departures';
$json = file_get_contents($url);
$results = json_decode($json, TRUE);
for ($x = 0; $x < count($results); $x++) {
echo $results[$x]['results']['flightNumber']."<br/>";
}
?>

If you do a debug (by the way, learn what is it), you will see, that your $results has one key: result, over which you can iterate with a simple foreach:
foreach ($results['result'] as $item) {
echo $item['flightNumber'];
}

You are trying to access the data returned from the API in the wrong order, do this instead:
<?php
$url = 'http://apis.is/flight?language=en&type=departures';
$json = file_get_contents($url);
$results = json_decode($json, TRUE);
// To loop through an array, use foreach instead of for
// It is easier to use
foreach($results['results'] as $result){
echo $result['flightNumber'].'<br />';
}
?>

<?php
$url = 'http://apis.is/flight?language=en&type=departures';
$json = file_get_contents($url);
$results = json_decode($json, TRUE);
foreach ($results['results'] as $res) {
echo $res['flightNumber']."<br/>";
}
?>

parse json from url using php and save in mysql db

I've a JSON response from some web service
{
"success":true,
"timestamp":1503291248,
"quotes":{
"SAD":"ABC",
"LOVE":"XYZ",
"FRIENDSHIP":"SOME",
"ENMITY":"LOREM IPSUM",
... //indicates there are a lot more categories
}
}
I have tried to echo data using this script
<?php
$url = 'MY_URL';
$content = file_get_contents($url);
$json = json_decode($content, true);
foreach ( $json as $idx=>$json ) {
echo $idx;
}
?>
this prints
successtermsprivacytimestampsourcequotes
but getting empty response, how can I echo/save above josn data in mySql?

<?php
$url = '{
"success":true,
"timestamp":1503291248,
"quotes":{
"SAD":"ABC",
"LOVE":"XYZ",
"FRIENDSHIP":"SOME",
"ENMITY":"LOREM IPSUM",
... //indicates there are a lot more categories
}
}';
$content = file_get_contents($url);
$json = json_decode($content, true);
foreach ( $json as $idx=>$json ) {
if(is_array($json))
{
foreach($json as $iidx=>$jjson)
{
echo $iidx.":".$jjson;
}
}
else
{
echo $idx.":".$json;
}
}
$ins_qry = 'INSERT INTO json_table(jsonvalues) values ("'.$json.'")';
$exec_qry = mysqli_query($link,$ins_qry);
?>
This will print json data.
To save this json data in mysql, you can directly insert the $json value into text column of a MySQL table.

$json = file_get_contents('url_here');
$obj = json_decode($json);
echo $obj->access_token;

Try this..
$url = 'MY_URL';
$content = file_get_contents($url);
$json = json_decode($content, true);
foreach ( $json as $val) {
echo $val['success']; //same for other keys
}

Data from JSON to php?

I need help with fetching only attraction data,
i have this php script on my website:
<?php $json_string = 'http://framecreators.nl/efteling/data.php'; $jsondata file_get_content($json_string); $json_o=json_decode(utf8_encode($data)); $attractie = $json_o['Id']['Type']; echo $attractie ?>
and this json data:
http://framecreators.nl/efteling/data.php
I need to convert only a Id and type, ff somebody can help me.

To access the data you're looking for, you'll need to do something like this:
foreach ($json_o['AttractionInfo'] as $a) {
echo $a['Id']; //or whatever you're planning to do with this data
ech0 $a['Type'];
}

<?php
$json_data = file_get_contents('http://framecreators.nl/efteling/data.php');
$data = json_decode($json_data);
$array = [];
foreach($data->AttractionInfo as $item) {
$array['id'][] = $item->Id;
$array['type'][] = $item->Type;
}
echo "<pre>";
print_r($array);
echo "</pre>";

$url = "http://framecreators.nl/efteling/data.php";
$content = file_get_contents($url);
$data = json_decode($content,TRUE);
$array = $data['AttractionInfo'];
foreach($array as $r)
{
echo "ID->".$r['Id'];
echo '';
echo "Type->".$r['Type'];
echo '';
}

$url = "http://framecreators.nl/efteling/data.php";
$content = file_get_contents($url);
$data = json_decode($content,TRUE);
$array = $data['AttractionInfo'];
if(is_array($array))
{
foreach($array as $r)
{
echo $r['Id'];
echo $r['Type'];
}
}

Loop a foreach json loop in another foreach json loop

I'm at a 24 hour hackathon trying to solve this so, excuse if it's a little rushed.
1st for each loop works fine, I'm getting a list of categories from this url
https://dev.xola.com/api/categories
I grab the list with this
$fullurl = "https://dev.xola.com/api/categories";
$string .= file_get_contents($fullurl); // get json content
$json_a = json_decode($string, true); //json decoder
then loop it with this
<?
foreach($json_a as $v)
{?>
echo $v ?}>
Now with the second for each look, I want to grab the items from this url
https://dev.xola.com/api/experiences
that match the category from the last url
so samething
$fullurl = "https://dev.xola.com/api/categories";
$string .= file_get_contents($fullurl); // get json content
$json_b = json_decode($string, true); //json decoder
here's the complete loop I tried
<?
$i=0;
foreach($json_a as $v)
$i++
{?>
echo $v ?
foreach($json_b as $x){?>
if($v==$x):
echo $v
endif;
?>
}?>

This will create a $result array with only the data that had the categories early acquired:
<?php
$categories_url = "https://dev.xola.com/api/categories";
$data = file_get_contents($categories_url);
$categories = json_decode($data, true);
$experiences_url = "https://dev.xola.com/api/experiences";
$data = file_get_contents($experiences_url);
$experiences = json_decode($data, true);
$result = array();
foreach ($experiences['data'] as $experience)
{
if (in_array($experience['category'], $categories))
{
$result[] = $experience;
}
}
print_r($result);
And you can easily read the result with:
foreach ($result as $item)
{
echo $item['category'], "\n";
echo $item['desc'], "\n";
//... other data available ...
}

The data structure of the experiences JSON is not the same as the categories JSON, therefore if($v==$x) will never match. If you want to find all results in experiences with a category from the categories url you can do the following:
<?
$BASE_URL = 'https://dev.xola.com/api/';
$categories = json_decode(file_get_contents($BASE_URL . 'categories'));
$experiences = json_decode(file_get_contents($BASE_URL . 'experiences'));
$matches = array();
foreach( $categories as $category ) {
foreach( $experiences->data as $experience ) {
if( $experience->category === $category ) {
$matches[] = $experience;
}
}
}
?>
<? foreach( $matches as $match ) : ?>
<? echo $match->category; ?><br>
<? endforeach; ?>

How to read json properties using PHP

How to get all pid and styles attribute from following json data with minimum loop in php
{"general":{"note":{"display":false}},"elements":{"the-1":{"index":1,"src":"shirt1.png","pid":"pid-3563130","angle":0,"styles":"background:transparent;top:51.80000305175781px;left:122px;width:80px;height:80px;","background":"transparent","pos":{"top":51.80000305175781,"left":122},"size":{"width":80,"height":80},"details":{"other":""}},"the-2":{"index":2,"src":"shirt2.png","pid":"pid-132002","angle":0,"styles":"background:transparent;top:44.80000305175781px;left:155px;width:80px;height:80px;","background":"transparent","pos":{"top":44.80000305175781,"left":155},"size":{"width":80,"height":80},"details":{"other":""}}}}
Thanks

$str = '{"general":{"note":{"display":false}},"elements":{"the-1":{"index":1,"src":"shirt1.png","pid":"pid-3563130","angle":0,"styles":"background:transparent;top:51.80000305175781px;left:122px;width:80px;height:80px;","background":"transparent","pos":{"top":51.80000305175781,"left":122},"size":{"width":80,"height":80},"details":{"other":""}},"the-2":{"index":2,"src":"shirt2.png","pid":"pid-132002","angle":0,"styles":"background:transparent;top:44.80000305175781px;left:155px;width:80px;height:80px;","background":"transparent","pos":{"top":44.80000305175781,"left":155},"size":{"width":80,"height":80},"details":{"other":""}}}}';
$arr = json_decode($str, true);
foreach ($arr['elements'] as $element) {
echo 'pid: ' . $element['pid'] . '<br />';
echo 'styles: ' . $element['styles'] . '<br />';
}

use json_decode function in PHP to get assosiative array.
<?php
$myJson = '{"general":{"note":{"display":false}},"elements":{"the-1":{"index":1,"src":"shirt1.png","pid":"pid-3563130","angle":0,"styles":"background:transparent;top:51.80000305175781px;left:122px;width:80px;height:80px;","background":"transparent","pos":{"top":51.80000305175781,"left":122},"size":{"width":80,"height":80},"details":{"other":""}},"the-2":{"index":2,"src":"shirt2.png","pid":"pid-132002","angle":0,"styles":"background:transparent;top:44.80000305175781px;left:155px;width:80px;height:80px;","background":"transparent","pos":{"top":44.80000305175781,"left":155},"size":{"width":80,"height":80},"details":{"other":""}}}}';
$myArray = json_decode($myJson,true);
$myInnerArray = $myArray['elements'];
$styles = array();
foreach($myInnerArray as $element)
$styles[] = $element['styles'];
print_r($styles);
?>

PHP has great abilities to handle json.
Let's assume the JSON string you've posted above is stored in a PHP variable $myJSON.
So we can easily store an associative array of these values into $myJSONArray like so:
$myJSONArray = json_decode( $myJSON, true );
So, now we just loop through:
foreach( $myJSONArray['elements'] as $arr => $key )
echo( "A PID: " . $key['pid'] . "\n" );
See it in action on Codepad.

$json = json_decode('{"general":{"note":{"display":false}},"elements":{"the-1":{"index":1,"src":"shirt1.png","pid":"pid-3563130","angle":0,"styles":"background:transparent;top:51.80000305175781px;left:122px;width:80px;height:80px;","background":"transparent","pos":{"top":51.80000305175781,"left":122},"size":{"width":80,"height":80},"details":{"other":""}},"the-2":{"index":2,"src":"shirt2.png","pid":"pid-132002","angle":0,"styles":"background:transparent;top:44.80000305175781px;left:155px;width:80px;height:80px;","background":"transparent","pos":{"top":44.80000305175781,"left":155},"size":{"width":80,"height":80},"details":{"other":""}}}}', true);
$elements = $json['elements'];
foreach($elements as $element){
$pid = $element['pid'];
$styles = $element['styles'];
echo $pid.': '.$styles.'<br />';
}
