Function name: stream_context_get_options()
Function Description: The stream_context_get_options() function returns an array of options for the specified context.
Applicable version: PHP 4 >= 4.3.0, PHP 5, PHP 7
Usage: stream_context_get_options ( resource $stream_or_context ) : array
parameter:
Return Value: This function returns an associative array containing options for the specified context.
Example:
// 创建一个上下文$context = stream_context_create([ 'http' => [ 'method' => 'POST', 'header' => 'Content-Type: application/json', 'content' => json_encode(['name' => 'John', 'age' => 30]) ] ]); // 获取上下文的选项$options = stream_context_get_options($context); // 输出选项数组print_r($options);
Output:
Array ( [http] => Array ( [method] => POST [header] => Content-Type: application/json [content] => {"name":"John","age":30} ) )
In the above example, we first create a context using the stream_context_create() function that contains options for an HTTP request. We then use the stream_context_get_options() function to get the options for the context and store it in the $options variable. Finally, we use the print_r() function to print out the contents of the $options array to see the options for the context.
In the output result, you can see that the option array contains the http key, and the corresponding value is an associative array, which contains the relevant options for HTTP requests, such as the request method, the request header, and the request body content.
