请问Warning: ftp_put() [function.ftp-put]: Opening BINARY mode data connection
请问题目的错误提示,是什么原因导致的呢?

这是PHP手册里的范例 也是你的答案
Here's a quick function that figures out the correct mode to use based on a file's extension.
function get_ftp_mode($file)
{
$path_parts = pathinfo($file);
if (!isset($path_parts['extension'])) return FTP_BINARY;
switch (strtolower($path_parts['extension'])) {
case 'am':case 'asp':case 'bat':case 'c':case 'cfm':case 'cgi':case 'conf':
case 'cpp':case 'css':case 'dhtml':case 'diz':case 'h':case 'hpp':case 'htm':
case 'html':case 'in':case 'inc':case 'js':case 'm4':case 'mak':case 'nfs':
case 'nsi':case 'pas':case 'patch':case 'php':case 'php3':case 'php4':case 'php5':
case 'phtml':case 'pl':case 'po':case 'py':case 'qmail':case 'sh':case 'shtml':
case 'sql':case 'tcl':case 'tpl':case 'txt':case 'vbs':case 'xml':case 'xrc':
return FTP_ASCII;
}
return FTP_BINARY;
}
// sample usage
ftp_get($conn_id, $local_file, $server_file, get_ftp_mode($server_file));
?>

你用了二进制模式?
------解决方案--------------------
服务器一般都是放在防火墙后面,因此 FTP 客户端程序如果需要穿越防火墙,需要开启被动模式,否则执行任何 ftp 命令都没有响应,直到出现 “最大执行时间超时” 的致命错误,导致程序终止运行...

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
