<para>
<function>min</function> returns the numerically lowest of the
parameter values.
</para>
<para>
If the first and only parameter is an array, <function>min</function>
returns the lowest value in that array. If the first parameter
is an integer, string or float, you need at least two parameters
and <function>min</function> returns the smallest of these values.
You can compare an unlimited number of values.
</para>
<note>
<para>
PHP will evaluate a non-numeric <type>string</type> as
<literal>0</literal>, but still return the string if it's seen as the
numerically lowest value. If multiple arguments evaluate to
<literal>0</literal>, <function>min</function> will use the first one
it sees (the leftmost value).
