# stream_context_get_default

(PHP 5 >= 5.1.0RC1)

stream_context_get_default -- Retreive the default streams context

## Description

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 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); ?>`
