php - url_get_contents working at second attempt -

-



hoping advice i'm writing here issue:

i have php script uses url_get_contents execute script , retrieve json domain. both ends under control.

the calling function is:

$this->url_to_call = 'http://example.com/b_controller.php'; $jsondata = array(     'table' => 'countries',     'key' => '44', );  $jsondataencoded = json_encode($jsondata); $post = file_get_contents(      $this->url_to_call, null, stream_context_create(         array(             'http' => array(                 'protocol_version' => 1.1,                 'user_agent'       => 'mozilla/5.0 (macintosh; intel mac os x 10_8_4) applewebkit/537.36 (khtml, gecko) chrome/27.0.1453.116 safari/537.36',                 'method'           => 'post',                 'header'           => "content-type: application/json\r\n"."connection: close\r\n" ."content-length: " . strlen($jsondataencoded) . "\r\n",                 'content'          => $jsondataencoded,             ),         )     ) ); $data = json_decode($post, true);

if run code, on first attempt get:

warning: file_get_contents(http://example.com/b_controller.php): failed open stream: error occurred during connection attempt because connected part did not respond after period of time, or there error in established connection because connected host not respond. in c:\xampp\htdocs\origin_com\a_controller.php on line 220

but if refresh page or add if( !$data ) $data = $post = file_get_contents( $this->url_to_cal......;

it responds right json.

if leave script 2 minutes , re-run again same error.

i have no clues why happening.

any advice appreciated.
