How do I send a POST request with PHP

Question

Actually I want to read the contents that come after the search query  when it is done  The problem is that the URL only accepts POST methods  and it does not take any action with GET method     I have to read all contents with the help of domdocument or file get contents    Is there any method that will let me send parameters with POST method and then read the contents via PHP

I recommend you to use the open-source package guzzle that is fully unit tested and uses the latest coding practices.

Installing Guzzle

Go to the command line in your project folder and type in the following command (assuming you already have the package manager composer installed). If you need help how to install Composer, you should have a look here.

php composer.phar require guzzlehttp/guzzle

Using Guzzle to send a POST request

The usage of Guzzle is very straight forward as it uses a light-weight object-oriented API:

// Initialize Guzzle client
$client = new GuzzleHttp\Client();

// Create a POST request
$response = $client->request(
    'POST',
    'http://example.org/',
    [
        'form_params' => [
            'key1' => 'value1',
            'key2' => 'value2'
        ]
    ]
);

// Parse the response object, e.g. read the headers, body, etc.
$headers = $response->getHeaders();
$body = $response->getBody();

// Output headers and body for debugging purposes
var_dump($headers, $body);

I use the following function to post data using curl   data is an array of fields to post  will be correctly encoded using http build query   The data is encoded using application x-www-form-urlencoded   function httpPost  url   data         curl   curl init  url       curl setopt  curl  CURLOPT POST  true       curl setopt  curl  CURLOPT POSTFIELDS  http build query  data        curl setopt  curl  CURLOPT RETURNTRANSFER  true        response   curl exec  curl       curl close  curl       return  response       Edward mentions that http build query may be omitted since curl will correctly encode array passed to CURLOPT POSTFIELDS parameter  but be advised that in this case the data will be encoded using multipart form-data   I use this function with APIs that expect data to be encoded using application x-www-form-urlencoded  That s why I use http build query

I was looking for a similar problem and found a better approach of doing this  So here it goes   You can simply put the following line on the redirection page  say page1 php    header  Location  URL   TRUE  307      Replace URL with to be redirected URL  e g  final php   I need this to redirect POST requests for REST API calls  This solution is able to redirect with post data as well as custom header values   Here is the reference link

There s another CURL method if you are going that way   This is pretty straightforward once you get your head around the way the PHP curl extension works  combining various flags with setopt   calls  In this example I ve got a variable  xml which holds the XML I have prepared to send - I m going to post the contents of that to example s test method    url    http   api example com services xmlrpc     ch   curl init  url    curl setopt  ch  CURLOPT POST  1   curl setopt  ch  CURLOPT POSTFIELDS   xml   curl setopt  ch  CURLOPT RETURNTRANSFER  true     response   curl exec  ch   curl close  ch     process  response   First we initialised the connection  then we set some options using setopt    These tell PHP that we are making a post request  and that we are sending some data with it  supplying the data  The CURLOPT RETURNTRANSFER flag tells curl to give us the output as the return value of curl exec rather than outputting it  Then we make the call and close the connection - the result is in  response

You could use cURL    lt  php   The url you wish to send the POST request to  url    file name     The data you want to send via POST  fields            VIEWSTATE          gt   state         EVENTVALIDATION    gt   valid       btnSubmit            gt   Submit        url-ify the data for the POST  fields string   http build query  fields      open connection  ch   curl init       set the url  number of POST vars  POST data curl setopt  ch CURLOPT URL   url   curl setopt  ch CURLOPT POST  true   curl setopt  ch CURLOPT POSTFIELDS   fields string      So that curl exec returns the contents of the cURL  rather than echoing it curl setopt  ch CURLOPT RETURNTRANSFER  true       execute post  result   curl exec  ch   echo  result    gt

I d like to add some thoughts about the curl-based answer of Fred Tanrikut  I know most of them are already written in the answers above  but I think it is a good idea to show an answer that includes all of them together    Here is the class I wrote to make HTTP-GET POST PUT DELETE requests based on curl  concerning just about the response body   class HTTPRequester                   description Make HTTP-GET call         param        url         param       array  params         return      HTTP-Response body or an empty string if the request fails or is empty             public static

       return  response            Improvements   Using http build query to get the query-string out of an request-array  you could also use the array itself  therefore see  http   php net manual en function curl-setopt php  Returning the response instead of echoing it  Btw you can avoid the returning by removing the line curl setopt  ch  CURLOPT RETURNTRANSFER  true    After that the return value is a boolean true   request was successful otherwise an error occured  and the response is echoed   See  http   php net en manual function curl-exec php Clean session closing and deletion of the curl-handler by using curl close  See  http   php net manual en function curl-close php Using boolean values for the curl setopt function instead of using any number  I know that any number not equal zero is also considered as true  but the usage of true generates a more readable code  but that s just my opinion  Ability to make HTTP-PUT DELETE calls useful for RESTful service testing    Example of usage  GET   response   HTTPRequester  HTTPGet  http   localhost service foobar php   array  getParam    gt   foobar       POST   response   HTTPRequester  HTTPPost  http   localhost service foobar php   array  postParam    gt   foobar       PUT   response   HTTPRequester  HTTPPut  http   localhost service foobar php   array  putParam    gt   foobar       DELETE   response   HTTPRequester  HTTPDelete  http   localhost service foobar php   array  deleteParam    gt   foobar       Testing  You can also make some cool service tests by using this simple class   class HTTPRequesterCase

If you by any chance are using Wordpress to develop your app  it s actually a convenient way to get authorization  info pages etc even for very simple stuff   you can use the following snippet    response   wp remote post   url  array  body    gt   parameters     if   is wp error   response               response- gt get error message     else           response  body       It uses different ways of making the actual HTTP request  depending on what is available on the web server  For more details  see the HTTP API documentation   If you don t want to develop a custom theme or plugin to start the Wordpress engine  you can just do the following in an isolated PHP file in the wordpress root   require once  dirname   FILE        wp-load php             your code   It won t show any theme or output any HTML  just hack away with the Wordpress APIs

Another alternative of the curl-less method above is to use the native stream functions    stream context create        Creates and returns a stream context with any options supplied in options preset   stream get contents        Identical to file get contents    except that stream get contents   operates on an already open stream resource and returns the remaining contents in a string  up to maxlength bytes and starting at the specified offset     A POST function with these can simply be like this    lt  php  function post request  url  array  params       query content   http build query  params      fp   fopen  url   r   FALSE     do not use include path     stream context create        http    gt           header     gt       header array does not need   r n           Content-type  application x-www-form-urlencoded            Content-Length      strlen  query content                  method     gt   POST          content    gt   query content                if   fp     FALSE        return json encode   error    gt   Failed to get contents               result   stream get contents  fp      no maxlength offset   fclose  fp     return  result

Try PEAR s HTTP Request2 package to easily send POST requests  Alternatively  you can use PHP s curl functions or use a PHP stream context   HTTP Request2 also makes it possible to mock out the server  so you can unit-test your code easily
