Retreive the default streams context (PHP 5 >= 5.1.0)
resource 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.

Example 2372. Using stream_context_get_default()

= array(
'header'=>"Accept-language: en\r\n" .
"Cookie: foo=bar",

$alternate_opts = array(
'header'=>"Content-type: application/x-www-form-urlencoded\r\n" .
"Content-length: " . strlen("baz=bomb"),

$default = stream_context_get_default($default_opts);
$alternate = stream_context_create($alternate_opts);

/* Sends a regular GET request to proxy server at
* For using context options specified in $default_opts

/* Sends a POST request directly to
* Using context options specified in $alternate_opts
readfile('', false, $alternate);
