You're all ASCII, it's not going to fall.

Is the data very large? is the post_max_size limit exceeded?

Isn't it nice that you're transferring files in C + + with curl? There's a lot of code online.

File_put_content can't write the number of bytes by itself.

File_put_content returns the number of bytes written to the data in the file

File_put_content returns the number of bytes written to the data in the file

The client sends 157962 to the server, and only 118425 is in suspense.

Is there any way to output the data before $_post["Zhaopian"?

Echo strlen ($_post["Zhaopian"]);
