Example code:
<?php
header("Content-type: text/html; charset=utf-8");
//利用PHP目录和文件函数遍历用户给出目录的所有的文件和文件夹，修改文件名称
function fRename($dirname){
if(!is_dir($dirname)){
echo "{$dirname}不是一个有效的目录！";
exit();
}
$handle = opendir($dirname);
$i = 1;
while(($fn = readdir($handle))!==false){
if($fn!='.'&&$fn!='..'){
echo "<br>将名为：".$fn."\n\r";
$curDir = $dirname.'/'.$fn;
if(is_dir($curDir)){
fRename($curDir);
}else{
$path = pathinfo($curDir);
//改成你自己想要的新名字
$newname = $path['dirname'].'/'.$i.'.'.$path['extension'];
echo "替换成:".$i.'.'.$path['extension']."\r\n";
rename($curDir,$newname);
$i++;
}
}
}
}

phpMyAdmin security best practices
Aug 17, 2025 am 01:56 AM
To effectively protect phpMyAdmin, multiple layers of security measures must be taken. 1. Restrict access through IP, only trusted IP connections are allowed; 2. Modify the default URL path to a name that is not easy to guess; 3. Use strong passwords and create a dedicated MySQL user with minimized permissions, and it is recommended to enable two-factor authentication; 4. Keep the phpMyAdmin version up to fix known vulnerabilities; 5. Strengthen the web server and PHP configuration, disable dangerous functions and restrict file execution; 6. Force HTTPS to encrypt communication to prevent credential leakage; 7. Disable phpMyAdmin when not in use or increase HTTP basic authentication; 8. Regularly monitor logs and configure fail2ban to defend against brute force cracking; 9. Delete setup and
Using XSLT Parameters to Create Dynamic Transformations
Aug 17, 2025 am 09:16 AM
XSLT parameters are a key mechanism for dynamic conversion through external passing values. 1. Use declared parameters and set default values; 2. Pass the actual value from application code (such as C#) through interfaces such as XsltArgumentList; 3. Control conditional processing, localization, data filtering or output format through $paramName reference parameters in the template; 4. Best practices include using meaningful names, providing default values, grouping related parameters, and performing value verification. The rational use of parameters can make XSLT style sheets highly reusable and maintainable, and the same style sheets can produce diversified output results based on different inputs.
