<para>
Binds columns in the result set to variables.
</para>
<para>
When <function>mysqli_stmt_fetch</function> is called to fetch data, the
MySQL client/server protocol places the data for the bound columns into
the specified variables <parameter>var</parameter>/<parameter>vars</parameter>.
</para>
<para>
A column can be bound or rebound at any time, even after a result set has
been partially retrieved. The new binding takes effect the next time
<function>mysqli_stmt_fetch</function> is called.
</para>
<note>
<para>
All columns must be bound after
<function>mysqli_stmt_execute</function> and prior to calling
<function>mysqli_stmt_fetch</function>.
</para>
</note>
<note>
<para>
Depending on column types bound variables can silently change to the
corresponding PHP type.
</para>
</note>
<tip>
<para>
This function is useful for simple results. To retrieve iterable result
set, or fetch each row as an array or object,
use <function>mysqli_stmt_get_result</function>.
