Does curl really not have a byte-limit setting for capturing content? For example, I just want the keyword of the header part of the Web page, it's a waste of time to collect all the words.

Title!

------Solution--------------------
The manual says
Curlopt_nobody TRUE to exclude the body from the output
Google says to exclude that the body from the output excludes the body from the outputs
Did not say not to get all the content

and
Get_headers Return all header information
Get_meta_tags extract all meta tags from a file content property

Weigh it yourself.
