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?

------解决方案--------------------
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));
?>
------解决方案--------------------
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...

How do you loop through all the values stored in a PHP session?How do you loop through all the values stored in a PHP session?Apr 26, 2025 am 12:06 AM

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

What happens if session_start() is called multiple times?What happens if session_start() is called multiple times?Apr 25, 2025 am 12:06 AM

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

How do you configure the session lifetime in PHP?How do you configure the session lifetime in PHP?Apr 25, 2025 am 12:05 AM

Configuring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
