posix_getpwnam
(PHP 4, PHP 5, PHP 7, PHP 8)
posix_getpwnam — Return info about a user by username
Description
posix_getpwnam(string
$username): array|falseReturns an array of information about the given user.
Parameters
-
username -
An alphanumeric username.
Return Values
On success an array with the following elements is returned, else
false is returned:
| Element | Description |
|---|---|
| name |
The name element contains the username of the user. This is
a short, usually less than 16 character "handle" of the
user, not the real, full name. This should be the same as
the username parameter used when
calling the function, and hence redundant.
|
| passwd | The passwd element contains the user's password in an encrypted format. Often, for example on a system employing "shadow" passwords, an asterisk is returned instead. |
| uid | User ID of the user in numeric form. |
| gid | The group ID of the user. Use the function posix_getgrgid() to resolve the group name and a list of its members. |
| gecos | GECOS is an obsolete term that refers to the finger information field on a Honeywell batch processing system. The field, however, lives on, and its contents have been formalized by POSIX. The field contains a comma separated list containing the user's full name, office phone, office number, and home phone number. On most systems, only the user's full name is available. |
| dir | This element contains the absolute path to the home directory of the user. |
| shell | The shell element contains the absolute path to the executable of the user's default shell. |
Examples
Example #1 Example use of posix_getpwnam()
<?php
$userinfo = posix_getpwnam("tom");
print_r($userinfo);
?>
The above example will output something similar to:
Array
(
[name] => tom
[passwd] => x
[uid] => 10000
[gid] => 42
[gecos] => "tom,,,"
[dir] => "/home/tom"
[shell] => "/bin/bash"
)
