chown

Name

chown — Changes the ownership of a file.

Synopsis

bool chown(file, user); string file: File to change mixed user: Username or UID

Returns

TRUE on success; FALSE on error

Description

chown() changes the ownership of the specified file. Since this function on nearly all UNIX systems is restricted to being run by the superuser, it won't operate correctly when PHP is run as a module (unless you run httpd as root). This function always returns TRUE on Win32 platforms.

Note

If safe mode is enabled, chown() can only change the ownership of files that are owned by the user running the command. In most cases, this is the user that the web server runs as.

Example

Example 300. Change a file's ownership to "user"

$file = "test_file";

if (! chown ($file, "user")) {
    echo  ("Unable to change file ownership");
}
