Digg  fileperms
Gets file permissions
(PHP 4, PHP 5)
Example 634. Display permissions as an octal value<?phpThe above example will output: 1777Example 635. Display full permissions<?phpThe above example will output: -rw-r--r--Related Examples ( Source code ) » fileperms Examples ( Source code ) » Get file permission Code Examples / Notes » filepermschinello
On Linux (not tested on Windows), if you want a chmod-like permissions, you can use this function: <?php function file_perms($file, $octal = false) { if(!file_exists($file)) return false; $perms = fileperms($file); $cut = $octal ? 2 : 3; return substr(decoct($perms), $cut); } ?> Using it: $ touch foo.bar $ chmod 0754 foo.bar <?php echo file_perms('foo.bar'); // prints: 754 echo file_perms('foo.bar', true); // prints 0754 ?> eelco
If you only want the permissions (lowest three octal numbers) you can use a bitwise AND to mask the bits: <?php fileperms($file) & 511; ?> asakurastar
If you need a function to return perms in format like (rwx etc) You can you use this code: function GetFilePerms($file) { $perms = fileperms($file); if (($perms & 0xC000) == 0xC000) {$info = 's'; } // Socket elseif (($perms & 0xA000) == 0xA000) {$info = 'l'; } // Symbolic Link elseif (($perms & 0x8000) == 0x8000) {$info = '-'; } // Regular elseif (($perms & 0x6000) == 0x6000) {$info = 'b'; } // Block special elseif (($perms & 0x4000) == 0x4000) {$info = 'd'; } // Directory elseif (($perms & 0x2000) == 0x2000) {$info = 'c'; } // Character special elseif (($perms & 0x1000) == 0x1000) {$info = 'p'; } // FIFO pipe else {$info = '?';} // Unknown // Owner $info .= (($perms & 0x0100) ? 'r' : '-'); $info .= (($perms & 0x0080) ? 'w' : '-'); $info .= (($perms & 0x0040) ? (($perms & 0x0800) ? 's' : 'x' ) : (($perms & 0x0800) ? 'S' : '-')); // Group $info .= (($perms & 0x0020) ? 'r' : '-'); $info .= (($perms & 0x0010) ? 'w' : '-'); $info .= (($perms & 0x0008) ? (($perms & 0x0400) ? 's' : 'x' ) : (($perms & 0x0400) ? 'S' : '-')); // World $info .= (($perms & 0x0004) ? 'r' : '-'); $info .= (($perms & 0x0002) ? 'w' : '-'); $info .= (($perms & 0x0001) ? (($perms & 0x0200) ? 't' : 'x' ) : (($perms & 0x0200) ? 'T' : '-')); return $info; } //Usage mode: //echo GetFilePerms("path/to/your/file"); paul2712
Do not forget: clearstatcache(); ============================== When ever you make a: mkdir($dstdir, 0770 )) or a: chmod($dstdir, 0774 ); You have to call: clearstatcache(); before you can call: fileperms($dstdir); |
