stream_bucket_make_writeable

Function name: stream_bucket_make_writeable()

Applicable version: PHP 5 >= 5.1.0, PHP 7

Function description: The stream_bucket_make_writeable() function marks the given stream bucket as writable, so that data can be read from the bucket.

Usage: stream_bucket_make_writeable(resource $brigade): bool

parameter:

• $brigade: represents a stream bucket.

Return value: Return true if successful, otherwise return false.

Example:

<?php // 创建一个 stream bucket $bucket = stream_bucket_new($stream, 'Hello, world!'); // 将 bucket 标记为可写 if (stream_bucket_make_writeable($bucket)) { // 从 bucket 中读取数据 echo $bucket---> data; // Output: Hello, world! } else { echo "Failed to make bucket writeable."; } ?>

In the above example, first use the stream_bucket_new() function to create a stream bucket and set its contents to "Hello, world!". Then use the stream_bucket_make_writeable() function to mark the bucket as writable. Finally, by accessing the $bucket->data property, we can read the data in the bucket and output it. If the stream_bucket_make_writeable() function executes successfully, it will return true, otherwise it will return false.
