How to extract and access data from JSON with PHP?
(1 answer)
Closed 11 months ago.
Here's the json
[{"location":"USA","email":"test#test.com","sex":"male","age":"Unkown","other":null,"profile":{"net":["55","56"],"networks":[{"site_url":"http://site.com","network":"test","username":"mike"},{"site_url":"http://site.com/2","network":"test2","username":"mike2"}]},"name":"Mike Jones","id":111}]
I wanted to know how I could echo out all networks so it echos out the site_url,network, and user for each of the 2.
How would I get "name" at the end out of there as well?
Tanks!

Use json_decode()
http://php.net/manual/en/function.json-decode.php
$data = json_decode(...your sstring ...);
echo $data[0]->name;

Use json_decode to decode the JSON data. Then you can iterate the array with foreach and access the site_url‍s of each array item with another foreach like:
$arr = json_decode($json);
foreach ($arr as $obj) {
foreach ($obj->profile->networks as $network) {
echo $network->site_url;
}
}

http://lt2.php.net/json_decode

Here's a straight-forward example doing the two things that you ask for (see inline comments).
$json = '[{"location":"USA","email":"test#test.com","sex":"male","age":"Unkown","other":null,"profile":{"net":["55","56"],"networks":[{"site_url":"http://site.com","network":"test","username":"mike"},{"site_url":"http://site.com/2","network":"test2","username":"mike2"}]},"name":"Mike Jones","id":111}]';
// "Decode" JSON into (dumb) native PHP object
$data = json_decode($json);
// Get the first item in the array (there is only one)
$item = $data[0];
// Loop over the profile.networks array
foreach ($item->profile->networks as $network) {
// echos out the site_url,network, and user
echo "site_url = " . $network->site_url . PHP_EOL;
echo "network = " . $network->network . PHP_EOL;
echo "user = " . $network->username . PHP_EOL;
}
// Get "name" at the end
echo "name = " . $item->name . PHP_EOL;
It should output (if you're viewing as HTML, it will be munged onto one line… don't output as HTML).
site_url = http://site.com
network = test
user = mike
site_url = http://site.com/2
network = test2
user = mike2
name = Mike Jones

Building on aviv's answer...
$data = json_decode(...your sstring ...);
echo $data[0]->location; // USA
...
echo $data[0]->profile->net[0]; // 55
echo $data[0]->profile->net[1]; // 56
echo $data[0]->profile->networks[0]->site_url; // http://site.com
echo $data[0]->profile->networks[0]->network; // test
echo $data[0]->profile->networks[0]->username; // mike
echo $data[0]->profile->networks[1]->site_url; // http://site.com/2
echo $data[0]->profile->networks[1]->network; // test2
echo $data[0]->profile->networks[1]->username; // mike2
echo $data[0]->name; // Mike Jones

Loop through associative array and assign values

I have an array:
$instructions = array (
array("step_no"=>"1","description"=>"Ensure that you have sufficient balance"),
array("step_no"=>"2","description"=>"Approve the request sent to your phone")
);
What I want is to loop through this array, which I have done, but I am now confused because I don't know how to get the output I desire.
foreach ($array as $key => $value) {
//echo $key . "\n";
foreach ($value as $sub_key => $sub_val) {
if (is_array($sub_val)) {
//echo $sub_key . " : \n";
foreach ($sub_val as $k => $v) {
echo "\t" .$k . " = " . $v . "\n";
}
} else {
echo $sub_key . " = " . $sub_val . "\n";
}
}
}
The above code loops through the array, but this line of code:
echo $sub_key . " = " . $sub_val . "\n";
gives me:
step_no = 1 description = Ensure that you have sufficient balance step_no = 2 description = Approve the request sent to your phone
when I change it to:
echo $sub_val . "\n";
it gives me:
1 Ensure that you have sufficient balance 2 Approve the request sent to your phone
But I what I truly want is:
1. Ensure that you have sufficient balance
2. Approve the request sent to your phone
Is this possible at all? Thanks.
$instructions = array (
array("step_no"=>"1","description"=>"Ensure that you have sufficient balance"),
array("step_no"=>"2","description"=>"Approve the request sent to your phone")
);
foreach($instructions as $instruction) {
echo $instruction['step_no'] . '. ' . $instruction['description'] . "\n";
}
If it's HTML you may want to use <ol> and <li>.
It smells like you are not running this script in command line but in browser. If so, then \n makes no visual effect (unless within <pre> block) and you u must use HTML tag <br /> instead. Also, drop concatenation madness and use variable substitution:
echo "{$sub_key}. = {$sub_val}<br/>";
You can simple achieve this way
<?php
$instructions = array (
array("step_no"=>"1","description"=>"Ensure that you have sufficient balance"),
array("step_no"=>"2","description"=>"Approve the request sent to your phone")
);
foreach($instructions as $instruction){
echo $instruction['step_no'].'. '.$instruction['description'].PHP_EOL;
}
?>
Alway keep it simple.

Nested foreach when reading XML (in PHP)

I need to create a CRON job that are weekly going to read a XML file. The XML file contains information about all the shows at a range of cinemas.
What I want to do is to read the XML file, extract the information I need about each show, and then upload each show to a database. But I run into trouble when I start nesting the for-loops.
I want each tuple to contain the following information:
Tile | FilmWebNr | Rating | Version | Center | Screen | Date | Time |
The URL for the XML is http://217.144.251.113/static/Shows_FilmWeb.php
Here is a pastebin where I try to list all the dates for each screen per Title.
Here is the result. As you can see, the dates is only displayed when there are more than 1 screen per Title. I dont get why the attributes array isn't always available.
I struggle with getting the last three (screen, date and time).
$map_url = "http://217.144.251.113/static/Shows_FilmWeb.php";
$response_xml_data = file_get_contents($map_url);
$data = simplexml_load_string($response_xml_data);
$array = (array) simplexml_load_string($response_xml_data);
$json = json_encode($array);
$configData = json_decode($json, true);
$movies = $configData['Performances']['Title'];
foreach ($movies as $title) {
echo "Title: " . $title['#attributes']['Name'] . '<br/>';
echo "FilmWebNr: " . $title['FilmWebNum'] . '<br/>';
echo "Rating: " . $title['TitleRating'] . '<br/>';
echo "Version: " . $title['TitleVersion'] . '<br/>';
echo "Center: " . $title['Center']['#attributes']['Name'] . '<br/>';
foreach ($title['Center']['Screen'] as $screen) {
//here I run into trouble
}
}
Let say I try to add the following in the inner loop:
$screen['#attributes']['Name'];
I get an error saying "Undefined index: #attributes".
So sometimes the attributes seems to be in an array, but sometimes not. Even though It is always a part of the XML.
Rather than going from XML-JSON-Arrays, it may be better to learn how to work with SimpleXML and you will find it's quite easy.
The main thing is to get used to how the various elements are layered and use foreach loops to iterate over the blocks...
$map_url = "http://217.144.251.113/static/Shows_FilmWeb.php";
$response_xml_data = file_get_contents($map_url);
$data = simplexml_load_string($response_xml_data);
$movies = $data->Performances->Title;
foreach ($movies as $title) {
echo "Title: " . $title['Name'] . '<br/>';
echo "FilmWebNr: " . $title->FilmWebNum . '<br/>';
echo "Rating: " . $title->TitleRating . '<br/>';
echo "Version: " . $title->TitleVersion . '<br/>';
echo "Center: " . $title->Center['Name'] . '<br/>';
foreach ($title->Center->Screen as $screen) {
echo "screen:".$screen['Name']. '<br/>';
foreach ( $screen->Date as $date ) {
echo "Date:".$date['Name']. '<br/>';
foreach ( $date->ShowID as $showID ) {
echo "Time:".$showID->Time. '<br/>';
}
}
}
}

How to print jSON values with loop

I am using the following code to print the output of the jSON response but when I try to print
echo $obj->HotelListResponse->customerSessionId; // This is working.
echo $obj->HotelListResponse->HotelList->HotelSummary->name; // This is not working.
When the response contains only one node then its printing perfectly but when there are multiple nodes with same name then its not printing. I tried using foreach just like the below. I also tried using while loop but still I am unable to print the list of hotel names.
My jSON decoded output is like http://pastebin.com/Fr21DkEk
Total code:
$url = "https://api.eancdn.com/ean-services/rs/hotel/v3/list?cid=55505&minorRev=99&apiKey=cbrzfta369qwyrm9t5b8y8kf&locale=en_AU&currencyCode=AUD&xml=<HotelListRequest><city>Brisbane</city><stateProvinceCode>QLD</stateProvinceCode><countryCode>AU</countryCode><arrivalDate>10/16/2014</arrivalDate><departureDate>10/18/2014</departureDate><RoomGroup><Room><numberOfAdults>2</numberOfAdults></Room></RoomGroup><numberOfResults>25</numberOfResults></HotelListRequest>";
$json = file_get_contents($url);
$obj = json_decode($json);
foreach($obj as $val) {
echo $val->HotelListResponse->HotelList->HotelSummary->name;
}
Try this
foreach($obj->HotelListResponse->HotelList->HotelSummary as $val) {
echo $val->name . '<br/>';
}
HotelSummary is an array:
echo $val->HotelListResponse->HotelList->HotelSummary[0]->name;
If you want all of the hotel summaries:
foreach($obj as $val) {
foreach($val->HotelListResponse->HotelList->HotelSummary as $sum) {
echo $sum->name;
}
}
Yes you can directly access them inside the foreach. Like this:
foreach($obj->HotelListResponse->HotelList->HotelSummary as $val) {
// ^^
// since you're interested on just names, you can point it directly on that object, then each of that batch is in `$val`
echo $val->name . '<br/>';
}
// or start from the parent
foreach($obj as $values) {
$customerSessionId = $values->customerSessionId;
echo $customerSessionId . '<hr/>';
$hotelList = $values->HotelList;
foreach($hotelList->HotelSummary as $hotelsummary) {
echo $hotelsummary->name . '<br/>';
}
}

annoying array tags.. want a pretty output

What i'm trying to do is make my output usable for a spreadsheet.
I want each item in the output without array tags or not mashed together but starting with an asterisk and ending with a % sign.
<?php
$file = file_get_contents('aaa.txt'); //get file to string
$row_array = explode("\n",$file); //cut string to rows by new line
$row_array = array_count_values(array_filter($row_array));
foreach ($row_array as $key=>$counts) {
if ($counts==1)
$no_duplicates[] = $key;
}
//do what You want
echo '<pre>';
print_r($no_duplicates);
//write to file. If file don't exist. Create it
file_put_contents('no_duplicates.txt',$no_duplicates);
?>
Maybe this would give you what you want:
$str = "*" . implode("% *", $no_duplicates) . "%";
echo '<pre>';
echo $str;
echo '</pre>';

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":""}}}}

$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 />';
}
