Here is a simple function to display UNIX like permissions:
function display_perms( $mode )
{
/* Determine Type */
if( $mode & 0x1000 )
$type='p'; /* FIFO pipe */
else if( $mode & 0x2000 )
$type='c'; /* Character special */
else if( $mode & 0x4000 )
$type='d'; /* Directory */
else if( $mode & 0x6000 )
$type='b'; /* Block special */
else if( $mode & 0x8000 )
$type='-'; /* Regular */
else if( $mode & 0xA000 )
$type='l'; /* Symbolic Link */
else if( $mode & 0xC000 )
$type='s'; /* Socket */
else
$type='u'; /* UNKNOWN */
/* Determine permissions */
$owner["read"] = ($mode & 00400) ? 'r' : '-';
$owner["write"] = ($mode & 00200) ? 'w' : '-';
$owner["execute"] = ($mode & 00100) ? 'x' : '-';
$group["read"] = ($mode & 00040) ? 'r' : '-';
$group["write"] = ($mode & 00020) ? 'w' : '-';
$group["execute"] = ($mode & 00010) ? 'x' : '-';
$world["read"] = ($mode & 00004) ? 'r' : '-';
$world["write"] = ($mode & 00002) ? 'w' : '-';
$world["execute"] = ($mode & 00001) ? 'x' : '-';
/* Adjust for SUID, SGID and sticky bit */
if( $mode & 0x800 )
$owner["execute"] = ($owner['execute']=='x') ? 's'
: 'S';
if( $mode & 0x400 )
$group["execute"] = ($group['execute']=='x') ? 's'
: 'S';
if( $mode & 0x200 )
$world["execute"] = ($world['execute']=='x') ? 't'
: 'T';
printf("%1s", $type);
printf("%1s%1s%1s", $owner['read'], $owner['write'],
$owner['execute']);
printf("%1s%1s%1s", $group['read'], $group['write'],
$group['execute']);
printf("%1s%1s%1s\n", $world['read'], $world['write'],
$world['execute']);
}
