PHP | ftp_exec()函数
ftp_exec()函数是PHP中的一个内置函数,用于在 FTP 服务器上执行命令。
句法:
ftp_exec( $ftp_connection, $command )
参数:该函数接受上面提到的两个参数,如下所述:
- $ftp_connection:必填参数。它指定用于执行 FTP 命令或功能的现有 FTP 连接。
- $command:必填参数。指定在连接成功的 FTP 服务器上执行的命令。
返回值:成功时返回True,失败时返回False。
笔记:
- 此函数适用于PHP 4.0.3 及更新版本。
- 以下示例无法在在线 IDE 上运行。所以尝试使用正确的 ftp 服务器名称、用户和密码在一些PHP托管服务器或 localhost 中运行。
例子:
PHP
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( $login ) {
// Checking whether logged in successfully or not
echo "
logged in successfully!";
// ftp_exec() executes the command
if (ftp_exec($ftp_connection, $command)) {
echo "
".$command." has been successfully executed.";
}
else {
echo "
Error while executing the command .";
}
}
else {
echo "
login failed!";
}
// Closing connection
if(ftp_close($ftp_connection)) {
echo "
Connection closed Successfully!";
}
}
?>
输出:
successfully connected to the ftp server!
logged in successfully!
ls-al > test.txt has been successfully executed.
Connection closed Successfully!
