<para>
Executes a statement prepared with
<function>odbc_prepare</function>.&return.success; The array
<parameter>parameters_array</parameter> only needs to be given if
you really have parameters in your statement.
</para>
<para>
Parameters in <parameter>parameter_array</parameter> will be
substituted for placeholders in the prepared statement in order.
Elements of this array will be converted to strings by calling this
function.
</para>
<para>
Any parameters in <parameter>parameter_array</parameter> which
start and end with single quotes will be taken as the name of a
file to read and send to the database server as the data for the
appropriate placeholder.

<note>
<para>
As of PHP 4.1.1, this file reading functionality has the
following restrictions:
<itemizedlist>
<listitem>
<simpara>
File reading is <emphasis>not</emphasis> subject to any
&safemode; or <link linkend="ini.open-basedir">open-basedir</link>
restrictions. This is fixed in PHP 4.2.0.
</simpara>
</listitem>
<listitem>
<simpara>
<link linkend="features.remote-files">Remote files</link>
are not supported.
</simpara>
</listitem>
<listitem>
<simpara>
If you wish to store a string which actually begins and ends
with single quotes, you must escape them or add a space or
other non-single-quote character to the beginning or end of
the parameter, which will prevent the parameter's being taken
as a file name. If this is not an option, then you must use
another mechanism to store the string, such as executing the
query directly with <function>odbc_exec</function>).
