对于大多数错误，参数是最适合的资源句柄。对于
|
||
<span class="function"><a href="oci_connect.html" class="function">oci_connect()</a></span>，<span class="function"><a href="oci_new_connect.html" class="function">oci_new_connect()</a></span>

或 <span class="function"><a href="oci_pconnect.html" class="function">oci_pconnect()</a></span>
|
||
的连接错误，不要传递参数。如果没有发现错误，<span class="function"><strong>oci_error()</strong></span>
|
||
返回 <strong><code>FALSE</code></strong>。<span class="function"><strong>oci_error()</strong></span>
|
||
以一个关联数组返回错误。在此数组中，<em>code</em>
|
||
是 oracle 错误代码而 <em>message</em> 是 oracle 的错误字符串。
