    <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.
