Returns the array element in the next place that's pointed by the
|
|
|
|
|
internal array pointer, or &false; if
|
|
|
|
|
there are no more elements.

<para>

<function>next</function> behaves like
|
|
|
|
|
<function>current</function>, with one difference. It advances
|
|
|
|
|
the internal array pointer one place forward before returning the
|
|
|
|
|
element. That means it returns the next array element and
|
|
|
|
|
advances the internal array pointer by one. If advancing the
|
|
|
|
|
internal array pointer results in going beyond the end of the
|
|
|
|
|
element list, <function>next</function> returns &false;.
|
|
|
|
|
<warning>
|
|
|
|
|
<para>
|
|
|
|
|
If the array contains empty elements, or elements that have a key
|
|
|
|
|
value of 0 then this function will return &false;
|
|
|
|
|
for these elements as well. To properly traverse an array which
|
|
|
|
|
may contain empty elements or elements with key values of 0 see the
|
|
|
|
|
<function>each</function> function.
