stream_context_get_default ( [array options] )
Returns the default stream context which is used whenever file operations
(fopen(), file_get_contents(), etc...)
are called without a context parameter. Options for the default context
can optionally be specified with this function using the same syntax as
stream_context_create().
options must be an associative
array of associative arrays in the format
$arr['wrapper']['option'] = $value.
Пример 1. Using stream_context_get_default()
<?php
$default_opts = array(
'http'=>array(
'method'=>"GET",
'header'=>"Accept-language: en\r\n" .
"Cookie: foo=bar",
'proxy'=>"tcp://10.54.1.39:8000"
)
);
$alternate_opts = array(
'http'=>array(
'method'=>"POST",
'header'=>"Content-type: application/x-www-form-urlencoded\r\n" .
"Content-length: " . strlen("baz=bomb"),
'content'=>"baz=bomb"
)
);
$default = stream_context_get_default($default_opts);
$alternate = stream_context_create($alternate_opts);
/* Sends a regular GET request to proxy server at 10.54.1.39
* For www.example.com using context options specified in $default_opts
*/
readfile('http://www.example.com');
/* Sends a POST request directly to www.example.com
* Using context options specified in $alternate_opts
*/
readfile('http://www.example.com', false, $alternate);
?>
