Trimitere date prin POST cu file_get_contents

Curs Php-mysql

Iata cum puteti trimite date prin POST cu file_get_contents() la o pagina php si sa obtineti continutul returnat. Se foloseste file_get_contents() impreuna cu functia: stream_context_create().
Functia stream_context_create($opt) creaza si returneaza un continut Stream cu datele din $opt.
- $opt e un array cu array-uri asociative de forma: $arr['wrapper']['option'] = $value.

Exemplu stream_context_create() si file_get_contents()

$postdata = http_build_query(['name'=>'some name', 'pass'=>'password']);  //data to send 'name=some+name&pass=password'
$opts = [
 'http' =>
  [
   'method'=> 'POST',  // GET or POST
   'header' => 'Content-type: application/x-www-form-urlencoded'. PHP_EOL .'Content-Length: '. strlen($postdata). PHP_EOL,
   'content' => $postdata
  ]
];
$send_data  = stream_context_create($opts);
$cnt = file_get_contents('http://domain.net/page.php', false, $send_data);  //send data and get the returned content

echo $cnt;

- Functia http_build_query($arr) genereaza un sir URL-encoded cu datele din $arr, returneaza un sir de forma: 'key1=val1&key2=val2'.
- Valoarea de la 'method' trebuie sa fie cu LITERE MARI (GET sau POST).
- La 'header' se adauga header-ele http care trebuie trimise la "page.php".
