stat

(PHP 3, PHP 4, PHP 5)

stat -- Gives information about a file

Description

array stat ( string filename )

Gathers the statistics of the file named by filename. If filename is a symbolic link, statistics are from the file itself, not the symlink. lstat() is identical to stat() except it would instead be based off the symlinks status.

In case of error, stat() returns FALSE. It also will throw a warning.

Returns an array with the statistics of the file with the following elements. This array is zero-based. In addition to returning these attributes in a numeric array, they can be accessed with associative indices, as noted next to each parameter; this is available since PHP 4.0.6:

Tabela 1. stat() and fstat() result format
