Returns an associative array with the following elements:
<table class="doctable table">
<caption><strong>The user information array</strong></caption>
<thead>
<tr>
<th>Element</th>
<th>Description</th>
</tr>
</thead>
<tbody class="tbody">
<tr>
<td>name</td>
<td>
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.
</td>
</tr>
<tr>
<td>passwd</td>
<td>
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.
</td>
</tr>
<tr>
<td>uid</td>
<td>
User ID, should be the same as the
<em><code class="parameter">uid</code></em> parameter used when calling the
function, and hence redundant.
</td>
</tr>
<tr>
<td>gid</td>
<td>
The group ID of the user. Use the function
<span class="function"><a href="function.posix-getgrgid.html" class="function">posix_getgrgid()</a></span> to resolve the group
name and a list of its members.
</td>
</tr>
<tr>
<td>gecos</td>
<td>
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.
</td>
</tr>
<tr>
<td>dir</td>
<td>
This element contains the absolute path to the
home directory of the user.
</td>
</tr>
<tr>
<td>shell</td>
<td>
The shell element contains the absolute path to the
executable of the user's default shell.
</td>
</tr>
