Hi i am using php file_get_contents method to get content. For getting high content it makes problem about bandwidth. I like to get gzip format data to get and decode to it later.
I collected a sample one but it show quite similar content length. here it is
<?php
function fetchUrl( $url, $gzip = false ) {
$raw = file_get_contents( $url, false, $context = stream_context_create( array(
'http' => array(
'method' => 'GET',
'header' => 'Accept-Encoding:' . ( $gzip ? 'gzip,deflate' : 'identity' ) . "\r\n",
)
) ) );
if ( $raw === false ) {
return false;
}
return $gzip ? gzdecode( $raw ) : $raw;
}
$src1 = fetchUrl( 'http://www.google.com' );
$src2 = fetchUrl( 'http://www.google.com', true );
echo strlen($src1). "<br>";
echo strlen($src2);
?>
which results
52233
52232
if there a better solution please help me or redirect me any solution present this site.
NB: i searched but do not get exact one, if i may wrong then provide that link where i get proper solution.
TIA.

I am new in PHP and I am trying to access file of another website of mine. So on my web #1 I am trying to send a POST request like this:
<?php
$url = 'http://localhost/modul_cms/admin/api.php'; //Web #2
$data = array(
"Action" => "getNewestRecipe",
"Secret" => "61cbe6797d18a2772176b0ce73c580d95f79500d77e45ef810035bc738aef99c3e13568993f735eeb0d3c9e73b22986c57da60a0b2d6413c5dc32b764cc5897a",
"User" => "joomla localhost",
);
// use key 'http' even if you send the request to https://...
$options = array(
'http' => array(
'header' => "Content-type: application/x-www-form-urlencoded\r\n",
'method' => 'POST',
'content' => http_build_query($data)
)
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
echo $result;
if($result === FALSE){
echo "Not working connection :(";
}else{
echo "HOORAY!";
var_dump($result);
}
And on my web #2 I have some kind of receiver I made. Now I need to return after selecting stuff from my database array of data. So I have code like this on my web #2:
<?php
$action = isset( $_POST["action"] ) ? $_POST["action"] : "";
$secret = isset( $_POST["secret"] ) ? $_POST["secret"] : "";
$user = isset( $_POST["user"] ) ? $_POST["user"] : "";
if(!empty($secret)){
if(!empty($user)){
switch($action){
case 'getNewestRecipe':
getNewestRecipe();
break;
case '':
error();
break;
default:
error();
break;
}
}
}
/* *************** FUNCTIONS ************* */
function getNewestRecipe(){
return array("msg" => "Here is your message!");
}
The problem is everything I get on my web #1 from the response is actually the echo I have there for knowing that the HTTP request reached something (so I've got the message "HOORAY!") but the
var_dump($response)
has empty value (not NULL or something it's literally this):
C:\Program Files (x86)\Ampps\www\joomla30\templates\protostar\index.php:214:string '' (length=0)
Thank you for any help!
On web#1 you are sending "Secret","User","Action" in upper-case, but on web#2 you are accessing $_POST['secret'] (lower-case). Because of this your code never gets to the call of getNewestRecipe() nor to your error() call, thus there is no content / a blank page, but also no error.
Also, you need to output the array your function returns in some way.
An array cannot simply be echod, so you need to serialize it. I suggest using json_encode: echo json_encode(getNewestRecipe());
I am trying to parse the ampersand value in a PHP string. It keeps returning blank values after I run my code and I am sure it is because of the 'ampersand' value in my variable ($area). I tried htmlspecialchars, html_entity_decode but to no avail. Please see code below:
<?php
/** Create HTTP POST */
$accomm = 'ACCOMM';
$state = '';
$city = 'Ballan';
$area = 'Daylesford & Macedon Ranges';
$page = '10';
$seek = '<parameters>
<row><param>SUBURB_OR_CITY</param><value>'. $city .'</value></row>
<row><param>AREA</param><value>'. $area .'</value></row>
</parameters>';
$postdata = http_build_query(
array(
'DistributorKey' => '******',
'CommandName' => 'QueryProducts',
'CommandParameters' => $seek)
);
$opts = array(
'http' => array(
'method' => 'POST',
'header' => 'Content-type: application/x-www-form-urlencoded',
'content' => $postdata)
);
/** Get string output of XML (In URL instance) */
$context = stream_context_create($opts);
$result = file_get_contents('http://national.atdw.com.au/soap/AustralianTourismWebService.asmx/CommandHandler?', false, $context);
?>
Pls how do I fix this
Thanks
XML is not HTML, and vice-versa. You cannot have a bare & in an XML document since it is a special character in XML documents. If you're just defining a static string like this your can replace it with & and move on with your day.
If you need to encode arbitrary strings that may or may not contain & or another XML special char, then you'll need functions like:
function xmlentity_encode($input) {
$match = array('/&/', '/</', '/>/', '/\'/', '/"/');
$replace = array('&', '>', '<', ''', '"');
return preg_replace($match, $replace, $input);
}
function xmlentity_decode($input) {
$match = array('/&/', '/>/', '/</', '/'/', '/"/');
$replace = array('&', '<', '>', '\'', '"');
return preg_replace($match, $replace, $input);
}
echo xmlentity_encode("This is testing & 'stuff\" n <junk>.") . "\n";
echo xmlentity_decode("This is testing & 'stuff" n >junk<.");
Output:
This is testing & 'stuff" n >junk<.
This is testing & 'stuff" n <junk>.
I'm fairly sure that PHP's XML libs do this for you transparently, [and also respecting the character set] but if you're manually constructing your own XML document then you have to ensure that you're aware of things like this.
For a few months I used a plugin that automatically downloads remote images and save them. However, I found there's about 15 000 unattached images, that are actually in posts. The plugin never attached the images to the post itself.
I have no idea what to do or how to solve this. I can't do it manually it will take ages.
Is there a way to scan the images and re-attach them to the respective post?
Update: After I run the below plugin that Sergiu mentioned. The report shows:
So it does seem to pick up the images in the post. I just wish it can attach it somehow to that post ID. Is there a way to modify the code?
In the plugin below. In line 525 i removed the code:
if ( stripos( $img, $path ) !== false ) {
$response .= 'Img already in media library<br>';
continue;
}
Now it attaches the images!
Only one last issue is that it makes new copies. I can't find a way for it to not re-download them. I prefer it to just attach them.
Here is, what i think the full piece of code responsible. Please suggest modifications:
http://pastebin.com/ePERuGjt#
/**
* Extracts all images in content adds to media library if external and updates content with new url
* #param object $post The post object
* #return array|bool Post id and images converted on success false if no images found in source
*/
function extract_multi( $post ) {
$html = $post->post_content;
$path = wp_upload_dir();
$path = $path['baseurl'];
$error = 0;
$response = '';
if ( stripos( $html, '<img' ) !== false ) {
$regex = '#<\s*img [^\>]*src\s*=\s*(["\'])(.*?)\1#im';
preg_match_all( $regex, $html, $matches );
if ( is_array( $matches ) && ! empty( $matches ) ) {
$new = array();
$old = array();
foreach( $matches[2] as $img ) {
/** Compare image source against upload directory to prevent adding same attachment multiple times */
$tmp = download_url( $img );
preg_match('/[^\?]+\.(jpg|JPG|jpe|JPE|jpeg|JPEG|gif|GIF|png|PNG)/', $img, $matches);
$file_array['name'] = basename($matches[0]);
$file_array['tmp_name'] = $tmp;
// If error storing temporarily, unlink
if ( is_wp_error( $tmp ) ) {
#unlink($file_array['tmp_name']);
$file_array['tmp_name'] = '';
continue;
}
$id = media_handle_sideload( $file_array, $post->ID );
if ( ! is_wp_error( $id ) ) {
$url = wp_get_attachment_url( $id );
$thumb = wp_get_attachment_thumb_url( $id );
array_push( $new, $url );
array_push( $old, $img );
$response .= '<p><img src="'.esc_url( $thumb ).'" style="max-width:100px;" /><br>';
$response .= '<a href="'. wp_nonce_url( get_edit_post_link( $id, true ) ).'" >'.get_the_title( $id ). '</a> Imported and attached</p>';
} else {
$response .= '<span style="color:red">Upload Error: Could not upload image. Check for malformed img src url</span><br>';
$error ++;
}
}
if( !empty( $new ) ) {
$content = str_ireplace( $old, $new, $html );
$post_args = array( 'ID' => $post->ID, 'post_content' => $content, );
if ( !empty( $content ) )
$post_id = wp_update_post( $post_args );
if ( isset( $post_id ) )
$response .= 'Post Content updated for Post: '.esc_html( $post->post_title).'<br>';
return array( 'error' => $error, 'response' => $response );
} else
$response .= 'No external images found for ' . esc_html( $post->post_title ) . '<br>';
return array ( 'error' => $error, 'response' => $response );
} else {
$response .= 'Error processing images for '. esc_html( $post->post_title ) .'<br>';
return array ( 'error' => $error, 'response' => $response );
}
} else {
$response .= 'No images found for ' . esc_html( $post->post_title) . '<br>';
return array ( 'error' => $error, 'response' => $response );
}
}
I am the original poster for this problem. After a few years, I came across this old post. I dug up the solution, in the hopes that it might help anyone in the future.
This is the modified media-tools.php file:
https://pastebin.com/8iUT78aP
Just install Media Tools plugin: https://github.com/c3mdigital/media-tools-for-WordPress
and overwrite the pastebin with the media-tools.php
Then, the plugin will actually re-attached all unattached media to the proper posts, also without re-downloading the images.
I hope this helps someone, as this problem is pure hell to solve.
This plugin seems to implement a feature dealing with exactly your problem.
i would suggest doing this way:
wget your site
wget -m http://yoursite.com
this should mirror all your site.
wget WILL NOT download unatached images.
check if everything was downloaded
delete wp-content directory (i mean dir where your images are stored)
upload files downloaded by wget.
next time use: DX Delete Attached Media Plugin.
it deletes all images attached to posts, when post is deleted.
I'm currently working on a project, where i have to get the status of a packet (sent with DHL). I read about the DHL API, which return an XML, but somehow there are no good examples out there. I have found some code snippets, but i have no clue where to register for API Key's.
Have anyone some links or examples for me?
Best regards,
Lukas
There is also this PHP client that can be used to consume the DHL XML API. It can handle all the different services exposed by DHL.
https://github.com/alfallouji/DHL-API
This client does not rely or depend on any framework and it should be fairly easy to integrate with your own code. You can check the samples folder for example on how to use it.
https://github.com/jklz/DHL-API-Tracking-PHP
It is used to connect into DHL using the XML-PI to track shipments using the Air Way Bill. it can handle a single tracking number or as many as you feed into it (has been tested with 250 and other then taking a little time to run had no problems). automatically takes and breaks the array of tracking numbers into chunks and then sends the request to DHL making sure not to pass the max number that can be tracked per request then returns the results as a array.
Quick and dirty without any third party lib and using official API:
<?php
$mode = 'sandbox'; // sandbox or production
$username = ''; // dhl developer account name, not email
$password = ''; // dhl developer account pass
$appname = 'zt12345'; // sandbox app
$apppass = 'geheim'; // sandbox app
$endpoint = 'https://cig.dhl.de/services/' . $mode . '/rest/sendungsverfolgung';
$payload = simplexml_load_string( '<?xml version="1.0" encoding="UTF-8" standalone="no"?><data appname="' . $appname . '" language-code="de" password="' . $apppass . '" piece-code="" request="d-get-piece-detail"/>' );
$shipmentids = array(
'00340434161094015902' // in sandbox only special numbers are allowed
);
$opts = array(
'http' => array(
'method' => "GET",
'header' => "Authorization: Basic " . base64_encode( "$username:$password" )
)
);
$context = stream_context_create( $opts );
foreach ( $shipmentids as $shipmentid ) {
$payload->attributes()->{'piece-code'} = $shipmentid;
$response = file_get_contents( $endpoint . '?' . http_build_query( array( 'xml' => $payload->saveXML() ) ), false, $context );
$responseXml = simplexml_load_string( $response );
$status = null;
// get last state
foreach ( $responseXml->data->data->data as $event ) {
$status = $event->attributes()->{'event-short-status'};
}
echo "Shipment " . $shipmentid . " is in state: " . $status . "\n";
}
There is a nice blog about this. It is unfortunately in German, but the code that is displayed there should still make sense to you.
Source: https://blog.simlau.net/dhl-tracking-api-php.html
Excerpt:
function dhl_tracking($trackingnumber)
{
$data = '<?xml version="1.0" encoding="ISO-8859-1" ?>';
$data .= '<data appname="nol-public" password="anfang" request="get-status-for-public-user" language-code="de">';
$data .= ' <data piece-code="'.$trackingnumber.'"></data>';
$data .= '</data>';
// URL bauen und File hohlen
$xml = simplexml_load_file(sprintf(
'http://nolp.dhl.de/nextt-online-public/direct/nexttjlibpublicservlet?xml=%s', $data
));
// FALSE, wenn Syntax oder HTTP Error
if ($xml === false) return false;
// Wandelt das SimpleXML Objekt in ein Array um
foreach ($xml->data->data->attributes() as $key => $value) {
$return[$key] = (string) $value;
}
return $return;
}
// Aufruf der Funktion
print_r(dhl_tracking($tracking_number));
This function will give back an array that will contain some tracking information:
Array
(
[status] => Die Sendung wurde erfolgreich zugestellt.
[recipient-id-text] => Nachbar
[product-name] => DHL PAKET
[pan-recipient-name] => SIMON LAUGER
)
(In fact, there is WAY more data in there.)
I hope this will help you in some way.
I have this method:
protected function _sendRequest($url, $method, Busca_Cxense_Data $data, $get = null) {
if (! isset ( $this->_urls [$url] )) {
throw new Busca_Cxense_Exception_Argument ( "El tipo de url enviado no es valido. (type: {$url})" );
}
$url = $this->_urls [$url] . $data->getUrlKey () . ($get ? "$get" : '');
$httpConfig = array ('http' => array ('method' => $method, 'request_fulluri' => $url, 'ignore_errors' => false ) );
if ($data->getSendJson ()) {
$json = $this->_setJson ( $data );
$header = "Content-Type: application/json\r\nContent-Length: " . strlen ( $json );
$httpConfig ['http'] ['content'] = $json;
} else {
$header = "Content-Type: text/html";
}
$httpConfig ['http'] ['header'] = $header;
$context = stream_context_create ( $httpConfig );
$stream = fopen ($url, 'r', false, $context);
$result = stream_get_contents($stream);
$headers = stream_get_meta_data($stream);
fclose($stream);
if (! $result) {
print_r ( $data );
var_dump ( $url );
print_r ( $httpConfig );
throw new Busca_Cxense_Exception_MethodCall ( "Bad call. \nString: $json\n" );
}
var_dump($result); exit;
return array ('json' => json_decode ( $result ), 'string' => $result, 'headers' => $headers );
}
As you can see, it create a context and open an stream. However, I have a error very strange. If I send this url:
http://sandbox.cxsearch.cxense.com/api/search/levelup?p_aq=query%28category^1:%22preview%20trailer%22,token-op=or%29&p_sm=idobject:desc&p_s=0&p_c=20&p_dr=title
it throws a bad request error, but if I send this other one:
http://sandbox.cxsearch.cxense.com/api/search/levelup?p_q=test&p_sm=idobject:desc&p_s=0&p_c=20&p_dr=title
it works as expected. Do I have to encode the url or something?
FIXED
I was able to figure what the problem was. I Only need to change the space for %20. And that was all...
400 response is returned by remote server, so you want to see specs/contact people on that side on how to build correct query.
The urls you provide look very different and remote system might have own validation rules on values, list of provided parameters, etc. Also it might require some specific headers and/or request body.
