stream_bucket_append

Function name: stream_bucket_append()

Function description: The stream_bucket_append() function is used to add a bucket to the tail of the stream.

Applicable version: PHP 5 >= 5.1.0, PHP 7

Syntax: stream_bucket_append(resource $brigade, object $bucket): bool

parameter:

• $brigade: The resource handle representing the bucket list of the stream.
• $bucket: represents the bucket object to add to the stream.

Return value: Return true if bucket is successfully added, otherwise false.

Example:

 <?php // 创建一个输入流$stream = fopen('input.txt', 'r'); // 创建一个bucket $bucket = stream_bucket_new($stream, 'Some data'); // 创建一个bucket brigade $brigade = stream_bucket_make_writeable($bucket); // 添加bucket 到流的尾部if (stream_bucket_append($brigade, $bucket)) { echo "Bucket added successfully!"; } else { echo "Failed to add bucket!"; } // 关闭流fclose($stream); ?>

In the above example, we first create an input stream $stream , then create a bucket $bucket using the stream_bucket_new() function, and then create a bucket brigade $brigade using the stream_bucket_make_writeable() function. Finally, add bucket $bucket to the tail of brigade $brigade by calling stream_bucket_append() function.

If the addition is successful, "Bucket added successfully!" will be output, otherwise "Failed to add bucket!" will be output. Finally, we turned off the input stream $stream .

Note: The stream_bucket_new() and stream_bucket_make_writeable() functions used in the example are to create helper functions for bucket and brigade, and are not functions in the PHP standard library. You can use appropriate functions instead according to the actual situation.
