PHP ftp_nb_get() 函数

Kwareji PHP FTP Function

定义和用法

ftp_nb_get() 函数从 FTP 服务器上获取文件并写入本地文件 (non-blocking)。

This function returns the following values:

  • FTP_FAILED (send/receive failed)
  • FTP_FINISHED (send/receive completed)
  • FTP_MOREDATA (send/receive in progress)

With ftp_get() Different, this function retrieves the file asynchronously. This means that your program can perform other operations while the file transfer is in progress.
