PHP - How To Tell: Is The Request For Http Or Https?

Hi Guys, 

Total PHP Noob here. I’ve run into a brick-wall and would appreciate some words of wisdom. 
I am working on a fairly complicated (at least to my skill level..)  home automation/IOT -project and unexpectedly have a big problem establishing a connection between the Internet and my home network. I’ve spent too many hours trying to solve this and eventually have reverted to a super basic Hello World -example to highlight the issue.

I can do this with a browser:

http://86.60.161.24  // will echo hello World

I can’t do this with my server:

<?php
  $url = 'http://86.60.161.24';
  $contents = file_get_contents($url);
  echo ($contents);
?>

It looks like the server-side HTTP -request never “touches” my Arduino-chip. No network activity detected. Obviously there is going to be a lot more data transfer happening but I need to solve this issue first. 

Is there anything I can do to make this work? Any and all input greatly appreciated. Cheers!!

 

I am testing a url for http post request. It connects to the site then it is disconnected. In fire fox it is giving error that the "connection was reset". In google chrome it is giving error that "Unable to load the webpage because the server sent no data". Following is the script.

I am new to curl and also new to http request response. The provider of this site tells me that everything is ok and it is sending data but i am not getting any data or any header of this site.

<?php

$data = '<?xml version="1.0" encoding="UTF-8"?><Request><Source ClientID="test_xml" Password="1234" /><RequestDetails Language="En"><SearchHotelPriceRequest><ServiceDestination DestinationType="city" DestinationCode="477" /><ImmediateConfirmationOnly>1</ImmediateConfirmationOnly><PeriodOfStay><CheckInDate>2012-03-01</CheckInDate><Duration>3</Duration></PeriodOfStay><Rooms> <Room NumberOfRooms="1" NumberOfAdults="2" /> </Rooms></SearchHotelPriceRequest></RequestDetails></Request>';
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, 'https://62.218.28.13:8443/monWebService/Request/v2');
curl_setopt($ch, CURLOPT_POST, $data);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$data = curl_exec($ch);
curl_close ($ch);
echo $data;
?>

Hello,
If i am not posting this question at right location then i apologize for it.

My problem is: I need to send HTTP get request to the webservice end point which must include the following http headers:

GET / HTTP/1.1
Host: apis.live.net
Accept: application/json
Content-Type: application/json
Authorization: WRAP access_token=AuthToken (here AuthToken is the Access Token String)

Note: I am using OAuth for getting an access Token but for getting contents I need to send an HTTP get request.

Any kind of help will be appreciated.
Thanks

Hello I am a total beginner and don't know first thing about php, but still trying to figure this out. 

So what I am trying to achieve is, send a http request from a software to my website with a ticket number, is it possible in php to receive that request and show it on a different webpage of the same site? 

It would be helpful if you can point me to some related articles. 

Hey guys, every now and then some of my scripts that consistently access headers seem to fail to open the stream. I'm running about 1-50 of these shell scripts at once, but it doesn't seem to make a difference weather I have 1 or 50 scripts open at once. I was wondering if there was a way to tell PHP: Alright, so it failed to open the http stream, I want you to try again until it works. I just want it to try again until it works, because when it doesn't load certain headers, things go very wrong. Thanks.

Here's an example of the code where the problem occurs:
$Attack = file_get_contents($MobLink."attack?user_id=".$UserID."&target_id=".$TargetID."&auth_key=".$AuthKey);
xml_parse_into_struct($iP=xml_parser_create(), $Attack, $iS, $iX);xml_parser_free($iP);
echo "$i :.:.: ".strip_tags($iS[$iX['MESSAGE'][0]]['value'])." :.:.:\n\n";

First thanks for any help that you can provide. I am somewhat new to PHP and this is the first "Web Service" I have had to create.

THE GOAL:
I need to pull XML data from another server. This company's API is setup so that you must give an IP and so you can only pull data from server to server instead of client to server. The data is pulled from the API using HTTP requests...very similar to YQL. (in essence the structured query is located in the URL).  This API also requires that my server only ping's their server every 10-15 mins, in order to cut down on server requests.

The logical thought in my head was to setup: a cron job to run a PHP script every 10 mins. The PHP scripts would then do the following:
1. Make the HTTP request
2. Open an existing file or create one (on my server)
3. Take the returned XML data from the API and write to the newly opened file.
4. Convert that XML to JSON.
5. Save the JSON
6. Cache the JSON file
7. STOP

My thought was to use curl and fopen for the first 3 steps. I found a basic script that will do this on PHP.net (as shown below). After that I am pretty much lost on how to proceed.


Code: [Select]
<?php

$ch = curl_init("http://www.example.com/");
$fp = fopen("example_homepage.txt", "w");

curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);

curl_exec($ch);
curl_close($ch);
fclose($fp);
?>

I would REALLY appreciate any help on this. Also, if you have the time to please comment and explain what you are doing in any code examples and why....that would HELP out a lot. I truly want to learn not just grab a snippet and run. So, your comments are vital for me.

thank!!!

Hey! I am trying to get a database table of users but am running into the error:

Warning: file_get_contents(http://protege-ontology-editor-knowledge-acquisition-system.136.n4.nabble.com/template/NamlServlet.jtp?macro=user_nodes&amp;user=68583) [function.file-get-contents]: failed to open stream: HTTP request failed!

I have looked it up and it may be a security thing...The urls I am getting are http://protege-ontology-editor-knowledge-acquisition-system.136.n4.nabble.com/template/NamlServlet.jtp?macro=user_nodes&user=68583 but the error adds an nodes&amp; part that screws it up. Any way around this?

Code: [Select]
<?PHP
$maxPage = 0;
$mainPage = "http://protege-ontology-editor-knowledge-acquisition-system.136.n4.nabble.com/template/NamlServlet.jtp?macro=app_people&node=136";
$mainContent = file_get_contents($mainPage);
$pattern = "/(?<=\"Page )\d\d+/";
preg_match_all($pattern, $mainContent, $pageNumb);

//find the max page
for($i=0;$i<sizeof($pageNumb[0]);$i++) {
if($pageNumb[0][$i] > $maxPage) {
$maxPage = $pageNumb[0][$i];

I am trying to figure how to code around this. I have a DOM scraper function that pulls urls from my database, opens the page, scrapes the data, and then moves onto the next URL to scrape. my issue is that if the page fails to load the script bombs and I have to restart it again. Trying to figure out how if the Code: [Select]
$html->find('div[class="itemHeader address"]') as $div fails to open the page it just skips the DOM inspection.

Here is my error...

Failed to open stream: HTTP Request failed.

Here is where I am at with my script....

Code: [Select]
mysql_select_db("scraped") or die(mysql_error());
$result = mysql_query("SELECT PKEY, URL, HASSCRAPED, SHOULDSCRAPE FROM CRAWLED WHERE SHOULDSCRAPE ='1' AND HASSCRAPED = '0'") or die(mysql_error()); 

while($row = mysql_fetch_array( $result )) {
mysql_query("UPDATE CRAWLED SET CRAWLED.HASSCRAPED =  '1' WHERE CRAWLED.URL = '" . $row['URL'] . "'");
$html = file_get_html($row['URL']);
foreach($html->find('div[class="itemHeader address"]') as $div) {
foreach($div->find('a') as $element){
$CleanData = CleanData($element->innertext);
if (strlen($CleanData[0]) > 5){
    mysql_query("INSERT INTO SCRAPED (ADDR1, CITY, STATE, ZIP, URL, DATE) VALUES ('" . $CleanData[0] . "','" . $CleanData[1] . "','" . $CleanData[2] . "','" . $CleanData[3] . "','". $row['URL'] . "','". date( 'Y-m-d H:i:s ' ) ."')");
        }
}
}

$html->clear();
unset($html);
unset($CleanData);
}

function CleanData($data) {
  $NewData = trim($data);
  $NewData = str_replace("<em>", "", $NewData);
  $AddrCityStateZip = explode("</em>",$NewData);
  $CityStateZip = explode(",",$AddrCityStateZip[1]);
  $StateZip = explode(' ',$CityStateZip[1]);
  $NewDataArray = array ($AddrCityStateZip[0], $CityStateZip[0], $StateZip[1], $StateZip[2]);
  return $NewDataArray;
  unset($NewData);
  unset($AddrCityStateZip);
  unset($CityStateZip);
  unset($StateZip);
}
mysql_close($link);
echo 'Scraping has compleated without error';

Doing something wrong, but don't see it.  How should one retrieve a POST parameter?  My $request->toArray()['html'] works, but I am sure it is not the "right way".

<?php
namespace App\DataPersister;
use ApiPlatform\Core\DataPersister\DataPersisterInterface;
use Symfony\Component\HttpFoundation\RequestStack;

class ArchivePersister implements DataPersisterInterface
{
    public function __construct(RequestStack $requestStack)
    {
        $request = $requestStack->getCurrentRequest();
        syslog(LOG_ERR, '$request->getMethod(): '.$request->getMethod());
        syslog(LOG_ERR, '$request->getContent(): '.$request->getContent());
        syslog(LOG_ERR, '$request->request->get(html): '.$request->request->get('html'));
        syslog(LOG_ERR, '$request->query->get(html): '.$request->query->get('html'));
        syslog(LOG_ERR, '$request->get(html): '.$request->get('html'));
        syslog(LOG_ERR, '$request->toArray(): '.json_encode($request->toArray()));
        syslog(LOG_ERR, '$request->toArray()[html]: '.$request->toArray()['html']);
    }
}

output

$request->getMethod(): POST
$request->getContent(): {"project":"/projects/1","description":"","html":"<p>{{ project_name }}</p>"}
$request->request->get(html):
$request->query->get(html):
$request->get(html):
$request->toArray(): {"project":"\/projects\/1","description":"","html":"<p>{{ project_name }}<\/p>"}
$request->toArray()[html]: <p>{{ project_name }}</p>

Trying to run a simple program that, when submitted, stores the username and password as cookies.  When clicking Submit, I get the error  "HTTP Error 405 - The HTTP verb used to access this page is not allowed". If the username and password fields are left blank when submitting it's suppose to give a message to enter a username and password, but, I still get that error message.

How do I only redirect the page when index.php is present?

so i have a number of websites on a server all work fine but when i put https://  in front of the other sites on the website's it redirects to another site on the server without changing domain name.   example:   http://www.example.com works fine https://www.example.com shows another site on the server   how can i stop this?   i tryed mod rewrites in htaccess but somehow isnt working?

Anyone know how to force URL with SSL with www.  

 <rewrite>
            <rules>               
                  <rule name="Redirect to HTTPS" stopProcessing="true">
<match url="(.*)" />
<conditions><add input="{HTTPS}" pattern="^OFF$" />
</conditions>
<action type="Redirect" url="https://www.site.com/{R:0}" redirectType="SeeOther" />
</rule>       
            </rules>
 </rewrite>

Please check the sample.
 

Hello,   I cannot work out this one.   I am loading a css file on an https page as: <link rel="stylesheet" type="text/css" href="/assets/fa687e60/jui/css/base/jquery-ui.css" />   But using the chrome element tool I see this error:   The page at 'https://mysite.com/deal/create' was loaded over HTTPS, but displayed insecure content from 'http://mysite.com/cs...bf9ee_1x400.png': this content should also be loaded over HTTPS.       Now I went in the css file and the code is like that:

.ui-state-highlight,

 .ui-widget-content .ui-state-highlight,

I'm trying to determine the best way to provide HTTPS access to a web application that I'm building.  I know that you can use the following code to redirect anyone manually accessing the http version of an https page:

Code: [Select]
if($_SERVER["HTTPS"] != "on") {
   header("HTTP/1.1 301 Moved Permanently");
   header("Location: "https://" . $_SERVER["SERVER_NAME"] . $_SERVER["REQUEST_URI"]);
   exit();
}

I have also heard that you could use mod_rewrite in Apache to achieve similar results.  The entire web application should use https so I just want to make sure that I'm setting this up correctly. 

Feedback on the best approach or other suggestions would be very helpful.  Thanks in advance.
