stream_context_get_default

Function name: stream_context_get_default()

Applicable version: PHP 4 >= 4.3.0, PHP 5, PHP 7

Function description: The stream_context_get_default() function is used to get the current default context option. This function returns the current default context option as an associative array.

Syntax: stream_context_get_default ( array $options = null )

parameter:

• options (optional): an associative array containing context options.

Return value: If successful, return an associative array containing the current default context options. If there is no default context option, false is returned.

Example:

 // 创建一个默认的上下文选项$defaultContext = stream_context_get_default(); // 输出默认上下文选项的内容print_r($defaultContext);

Output example:

 Array ( [http] => Array ( [method] => GET [header] => User-Agent: PHP ) [ssl] => Array ( [verify_peer] => true [verify_peer_name] => true ) )

In the example above, we first use the stream_context_get_default() function to get the current default context option and store the result in the $defaultContext variable. Then, we use the print_r() function to print out the contents of the default context option. The output results show an associative array containing two context options, http and SSL, as well as their specific configuration information.

Note that the actual output may vary because the default context options may vary depending on factors such as PHP version, server configuration, etc.
