PHP ftp_exec()函数介绍和示例解释

ftp_exec()函数是PHP中的内置函数, 用于在FTP服务器上执行命令。
【PHP ftp_exec()函数介绍和示例解释】语法如下:

ftp_exec( $ftp_connection, $command )

参数:此函数接受上述和以下所述的两个参数:
  • $ ftp_connection:它是必填参数。它指定用于执行FTP命令或功能的现有FTP连接。
  • $ command:它是必填参数。它指定要在成功建立连接的FTP服务器上执行的命令。
返回值:成功返回True, 失败返回False。
注意:
  • 此功能可用于PHP 4.0.3和更高版本。
  • 以下示例无法在在线IDE上运行。因此, 请尝试使用适当的ftp服务器名称, 用户名和密码在某些PHP托管服务器或localhost中运行。
例子:
< ?php// Connect to FTP server // Use a correct ftp server $ftp_server = "localhost" ; // Use correct ftp username $ftp_username = "username" ; // Use correct ftp password corresponding // to the ftp username $ftp_userpass = "password" ; // Command to be executed on FTP server $command = "ls-al > test.txt" ; // Establishing ftp connection $ftp_connection = ftp_connect( $ftp_server ) or die ( "Could not connect to $ftp_server" ); if ( $ftp_connection ) { echo "successfully connected to the ftp server!" ; // Logging in to established connection with // ftp username password $login = ftp_login( $ftp_connection , $ftp_username , $ftp_userpass ); if ( $login ) {// Checking whether logged in successfully or not echo "< br> logged in successfully!" ; // ftp_exec() executes the command if (ftp_exec( $ftp_connection , $command )) { echo "< br> " . $command . " has been successfully executed." ; } else { echo "< br> Error while executing the command ." ; } } else { echo "< br> login failed!" ; }// Closeingconnection if (ftp_close( $ftp_connection )) { echo "< br> Connection closed Successfully!" ; } } ?>

输出如下:
successfully connected to the ftp server! logged in successfully! ls-al > test.txt has been successfully executed. Connection closed Successfully!
