Why? Solution

Why? PHPcodefunctiondelDir ($ dir) {$ arr = getcTime ($ dir); asort ($ arr); // $ arr = array ('file name' = & gt; 'creation time') why?

PHP code

  Function delDir ($ dir) {$ arr = getcTime ($ dir); asort ($ arr ); // $ arr = array ('file name' => 'creation time'); // getDirSize ($ dir) is the function for obtaining the folder size based on the folder directory foreach ($ arr as $ key => $ value) {$ size = getDirSize ($ dir); if ($ size> 2048) {unlink ($ key) ;}else {break ;}}}

In win, it is OK. However, the following error occurs in linux.
Warning: unlink (/usr/local/lamp/test/2. text) [function. unlink]: Permission denied in/usr/local/lamp/apache2/htdocs/test. php on line 112
I checked on the Internet, and some said it was a permission issue, but I set the permission for the test folder to 777 ,,,
What are the reasons for this? It really hurts...


------ Solution --------------------
Use is_writable to check the permissions before unlink.

PHP may only use the user name (usually 'nobody') for running webserver to access the file.

Do you want to delete files other than the website?

No. this is just a test file to delete the log file.

Standard answer

Cut

2. the text permission is not correct. you can allocate xx to this file to the apache operation...


The account for running apache is root. Permission:-rwxrwxrwx root
I'm sure and sure ......


... The zookeeper of apache is root ?? So painful ......
