Show only a specific part of html response in php - php

Question

I am trying to get tracking information from amazon using provided url
https://www.amazon.co.uk/progress-tracker/package/ref=pe_3187911_189395841_TE_typ?_encoding=UTF8&from=gp&itemId=&orderId=203-2171364-3066749&packageIndex=0&shipmentId=23796758607302
I am getting response using file_get_contents() function in php,
what I want is to show only that part of the response which contains the tracking information as an output of my php script and eliminate/hide all the unnecessary content from file_get_contents() response.

One way to do what you're looking for is use DomDocument to filter out the json data in the source ($file) and then use a recursive function to get the elements you need.
You can set the elements you need using an array, $filter. In this example we've taken a sample of some of the available data, i.e. :
$filter = [
'orderId', 'shortStatus', 'promiseMessage',
'lastTransitionPercentComplete', 'lastReachedMilestone', 'shipmentId',
];
The code
<?php
$filename = 'https://www.amazon.co.uk/progress-tracker/package/ref=pe_3187911_189395841_TE_typ?_encoding=UTF8&from=gp&itemId=&orderId=203-2171364-3066749&packageIndex=0&shipmentId=23796758607302';
$file = file_get_contents($filename);
$trackingData = []; // store for order tracking data
$html = new DOMDocument();
#$html->loadHTML($file);
foreach ($html->getElementsByTagName('script') as $a) {
$data = $a->textContent;
if (stripos($data, 'shortStatus') !== false) {
$trackingData = json_decode($data, true);
break;
}
}
// set the items we need
$filter = [
'orderId', 'shortStatus', 'promiseMessage',
'lastTransitionPercentComplete', 'lastReachedMilestone', 'shipmentId',
];
// invoke recursive function to pick up the data items specified in $filter
$result = getTrackingData($filter, $trackingData);
echo '<pre>';
print_r($result);
echo '</pre>';
function getTrackingData(array $filter, array $data, array &$result = []) {
foreach($data as $key => $value) {
if(is_array($value)) {
getTrackingData($filter, $value, $result);
} else {
foreach($filter as $item) {
if($item === $key) {
$result[$key] = $value;
}
}
}
}
return $result;
}
Output:
Array
(
[orderId] => 203-2171364-3066749
[shortStatus] => IN_TRANSIT
[promiseMessage] => Arriving tomorrow by 9 PM
[lastTransitionPercentComplete] => 92
[lastReachedMilestone] => SHIPPED
[shipmentId] => 23796758607302
)

Answer 2

Try this
<?php
$filename = 'https://www.amazon.co.uk/progress-tracker/package/ref=pe_3187911_189395841_TE_typ?_encoding=UTF8&from=gp&itemId=&orderId=203-2171364-3066749&packageIndex=0&shipmentId=23796758607302';
$file = file_get_contents($filename);
$html = new DOMDocument();
#$html->loadHTML($file);
foreach($html->getElementsByTagName('span') as $a) {
$property=$a->getAttribute('id');
if (strpos($property , "primaryStatus"))
print_r($property);
}
?>
It should show "Arriving tomorrow by 9 PM" status.
