<para>
The <function>glob</function> function searches for all the pathnames
matching <parameter>pattern</parameter> according to the rules used by
the libc glob() function, which is similar to the rules used by common
shells. No tilde expansion or parameter substitution is done.
</para>
<para>
Returns an array containing the matched files/directories, an empty array
if no file matched or &false; on error.
