stream_bucket_new

Function name: stream_bucket_new

Function Description: The stream_bucket_new function is used to create a new stream bucket object that can be used to perform data operations on the stream.

Applicable version: PHP 5 >= 5.1.0, PHP 7

Syntax: stream_bucket_new(resource $stream, string $buffer)

parameter:

• $stream: Required, indicating the input resource flow.
• $buffer: Required, indicating the data in the stream bucket.

Return value: Returns a newly created stream bucket object.

Example:

 // 创建一个流桶对象$stream = fopen('data.txt', 'r'); $bucket = stream_bucket_new($stream, 'example data'); // 打印流桶对象信息var_dump($bucket); // 将流桶对象放入流中stream_bucket_append($stream, $bucket); // 读取流中的数据while (($data = fread($stream, 1024)) !== false) { echo $data; } // 关闭流fclose($stream);

In the above example, we first use the fopen function to open a file named "data.txt" and assign it to the $stream variable. Then, we use the stream_bucket_new function to create a new stream bucket object containing the string "example data". Next, we use the stream_bucket_append function to put the stream bucket object into the stream. Finally, we use the fread function to read the data in the stream step by step and output it to the screen. Finally, we use the fclose function to close the stream.

Note that the stream_bucket_new function must be used on the open stream, otherwise an error will occur.
