PHP - How To Send Http Get Request To The Webservice End Point?

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!!!

Quick question for you guys.

I am collecting payment data for a product.

Is it possible to send data from my form via http directly into another payment form via the post http headers?

So say if i had all the details payment info and address info and i matched my form exactly to theirs. Is it possible to write a php script to send the data from my form directly to another websites form to make an order, say amazon or a big site like this?

?first_name=samuel&last_name=east&action=Submit

Any Help?

Thanks

hi there - first attempt at programming in PHP so please bear with my novice attempts (not much programming experience in any languege really)
i am building a site which hosts mp3s. I have MySQL database with one of the fields contating descriptive keywords for the tracks (such as slow, chilled, intense etc)
i have created an html page with search form that send data to php file which runs a query of the keywords field - and all works fine

now i want that in addition to the search form (with an input text box for the search criteria and the submit button) i will have a 'cloud' of key words - clickable links - that will send the data to the PHP query file (clicking on slow will search for tracks described with 'slow' and so on) - any ideas how do send data by clicking on a link?

my html form is:

Code: [Select]
<body bgcolor="white">
<form action="test3.php" target="main" method="post">

<input type="text" name="searchkeywords" size=100><br>
<input type="submit" value="Search">
<input name="searchkeywords" value="slow" type="submit">



</form>

<DIV align="center" style="left : 240px; position : absolute; top : 100px;"><iframe src ="test3.php" width="1000" height="800" name="main" frameborder="2" scrolling="no">
  <p>Your browser does not support iframes.</p>
</iframe></DIV>
</body>
my php query file is:
Code: [Select]
<?php
$con = mysql_connect("localhost","root","password");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }
mysql_select_db("test", $con);

$result = mysql_query("SELECT * FROM music WHERE keywords LIKE '%$_POST[searchkeywords]%'");

  echo "</tr>";
  }
echo "</table>";

// some code

mysql_close($con);
?>

How do I send multiple headers with this code?

Code: [Select]

<?php

$postdata = http_build_query(
    array(
        'var1' => 'some content',
        'var2' => 'doh'
    )
);

$opts = array('http' =>
    array(
        'method'  => 'POST',
        'header'  => 'Content-type: application/x-www-form-urlencoded',
        'content' => $postdata
    )
);

$context  = stream_context_create($opts);

$result = file_get_contents('http://example.com/submit.php', false, $context);

?>

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

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';

Hi,

For about a month, I have been trying to figure out why my code will not return anything after posting a wwwForm (I have also tried the newer equivalent of this function but I had no luck with that either.) The nameField and passwordField are taken from text boxes within the game and the code used in my login script is copied and pasted from a Register script but I have changed the file location to the login.php file. The register script works fine and I can add new users to my database but the login script only outputs "Form Sent." and not the "present" that should return when the form is returned and it never gets any further than that point meaning that it lets the user through with no consequence if they use an invalid name because the script never returns an answer. What should I do to fix this?

Thanks,

Unity Code:

using System.Collections;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.Networking;

public class Login : MonoBehaviour
{
    public InputField nameField;
    public InputField passwordField;

    public Button acceptSubmissionButton;

    public void CallLogInCoroutine()
    {
        StartCoroutine(LogIn());
    }

    IEnumerator LogIn()
    {
        WWWForm form = new WWWForm();
        form.AddField("username", nameField.text);
        form.AddField("password", passwordField.text);
        WWW www = new WWW("http://localhost/sqlconnect/login.php", form);
        Debug.Log("Form Sent.");
        yield return www;
        Debug.Log("Present");        if (www.text[0] == '0')
        {
            Debug.Log("Present2");
            DatabaseManager.username = nameField.text;

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.
