php 删除日志文件
就是现在我有一个存放日志的文件夹,需要怎么做才能用程序做到将较早的日志文件进行删除?大神们有方法么?
回复讨论(解决方案)
foreach(glob('日志文件目录/*.*') as $fn) { if(filemtime($fn) < 指定的时间) unlike($fn);}
可以写个脚本删呢,一天跑一次检查过期(比对当前时间和日志的最后修改时间或者创建时间)的日志文件给予删除
脚本的话比如这样,删除内容修改超过7天的文件
find ./ -mtime +7 | xargs rm -rf
是要用php完成这个工作呢,就是我有百度看有提供将文件夹里面的文件按照时间进行排序,但是我使用了都是不可以的。。。
这是我的代码
function dir_size($dir,$url){
$dh = @opendir($dir); //打开目录,返回一个目录流
$return = array();
$i = 0;
while($file = @readdir($dh)){ //循环读取目录下的文件
if($file!='.' and $file!='..'){
$path = $dir.'/'.$file; //设置目录,用于含有子目录的情况
if(is_dir($path)){
}elseif(is_file($path)){
$filesize[] = round((filesize($path)/1024),2);//获取文件大小
$filename[] = $path;//获取文件名称
$filetime[] = date("Y-m-d H:i:s",filemtime($path));//获取文件最近修改日期
$return[] = $url.'/'.$file;
}
}
}
@closedir($dh); //关闭目录流
array_multisort($filetime,SORT_DESC,SORT_STRING, $files);//按时间排序
return $return; //返回文件
}
dir_size("htdocs","htdocs");
?>
运行后出现问题
array_multisort(): Argument #1 is expected to be an array or a sort flag
最好的结果是我希望php运行后能将文件按照时间的顺序进行排列,这样我就能用函数有选择性的进行文件的删除。。。
学习了。。。。
array_multisort($filetime,SORT_DESC,SORT_STRING, $files);//按时间排序
$files 在哪里赋值的?
array_multisort($filetime,SORT_DESC,SORT_STRING, $files);//按时间排序
$files 在哪里赋值的?
我查了下函数的用法,知道了array_multisort函数的用法,最后一个给的参数应该是一个数组,但是我不知道怎么给第四个参数赋值。$files应该是指文件里面的所有文件,我不知道怎么去使用。。$files=$return[] = $url.'/'.$file;?
我把$files改成了$return还是没有用。。。
函数可改写为
function dir_size($dir,$url){ $dh = @opendir($dir); //打开目录,返回一个目录流 $return = array(); $i = 0; while($file = @readdir($dh)){ //循环读取目录下的文件 if($file!='.' and $file!='..'){ $path = $dir.'/'.$file; //设置目录,用于含有子目录的情况 if(is_dir($path)){ }elseif(is_file($path)){ $files[] = array( 'filename' => $path,//获取文件名称 'filesize' => round((filesize($path)/1024),2),//获取文件大小 'filetime' => date("Y-m-d H:i:s",filemtime($path)),//获取文件最近修改日期 'return' => $url.'/'.$file ); $filetime[] = filemtime($path);//获取文件最近修改日期 } } } @closedir($dh); //关闭目录流 array_multisort($filetime,SORT_DESC,SORT_STRING, $files);//按时间排序 return $files; //返回文件}
恩恩,我用了您的代码,发现可以使用的。
然后我发现还有一种方式就是直接把$files放在替换成$return,因为之前的数据都是存在return里面的。

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP handles file uploads through the $\_FILES variable. The methods to ensure security include: 1. Check upload errors, 2. Verify file type and size, 3. Prevent file overwriting, 4. Move files to a permanent storage location.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

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.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.
