Definition and usage

The stat() function returns information about the file.

Syntax

fstat(file)

Parameters

file Required. Specifies the documents to be checked.

Description

Get the statistical information of the file specified by file. If file is a symbolic link, the statistics are about the connected file itself, not the symbolic link.

If an error occurs, stat() returns false and issues a warning.

The returned array contains the statistical information of the file. The array has the cells listed below, and the array subscript starts from zero. In addition to numeric indexes, as of PHP 4.0.6 they are also accessible via associative indexes.

The return format of stat()

● 0 dev device name

● 1 ino number

● 2 mode inode protection mode

● 3 nlink number of connected connections

● 4 uid Owner's user id

Tips and comments

Tip: lstat() is similar to stat(), except that it returns the status of the symbolic connection.

Note: The results of this function will be cached. Please use clearstatcache() to clear the cache.
