WP_Http_Curl::stream_body( resource $handle, string $data ): int
- Since
- 3.6.0
- Source
wp-includes/class-wp-http-curl.php:391
Description
The contents of the document are passed in chunks, and are appended to the $body property for temporary storage. Returning a length shorter than the length of $data passed in will cause cURL to abort the request with CURLE_WRITE_ERROR.
Parameters
$handleresource- cURL handle.
$datastring- cURL request body.
Return
int- Total bytes of data written.
Cost profile
Measured from the compiled opcodes, not from a stopwatch. Every number here is identical on any machine that runs the same PHP version, and every function in core is ranked by these figures.

Reads or writes the filesystem via fwrite().
No loop in the body: the same number of instructions runs whatever you pass in.
Executed per call on PHP 8.4, depending on the branch taken. The body compiles to 30.
Nothing here hands control to plugin code.
Nothing in core calls this; the cost is only what you spend yourself.

What one call costs · 2 distinct outcomes
One number would be a lie: the work depends on which branch runs. These are every distinct cost WP_Http_Curl::stream_body() can have, taken from its control-flow graph on PHP 8.4.
| When | Instructions | Calls it makes |
|---|---|---|
| always | 13–24 | none |
| always | 16–27 | fwrite() |
Across PHP versions
| PHP | Compiled | Executed | Branches | Notes |
|---|---|---|---|---|
7.4 | 33 | 13–30 | 3 | More instructions than PHP 8.4 |
8.1 | 33 | 13–30 | 3 | More instructions than PHP 8.4 |
8.2 | 33 | 13–30 | 3 | More instructions than PHP 8.4 |
8.3 | 33 | 13–30 | 3 | More instructions than PHP 8.4 |
8.4 | 30 | 13–27 | 3 | Compiles to the same instructions |
Oldest PHP that compiles this body: 7.4. An instruction is not a fixed amount of time, so a version with the same count is not necessarily the same speed; what the count rules out is a difference in the work itself.
