PHP处理Oracle的CLOB实例_PHP

clob oracle php

本文实例简述了PHP处理Oracle的CLOB的方法。分享给大家供大家参考。具体方法如下:

1. 写入数据
 
在使用PDO的预处理方法时,如果使用bindParam()等而不指定字段的数据类型或使用execute(),PDO都会默认为string类型,并且限定一个默认长度

所以在存clob类型字段时必须使用bindParam()或bindValue()等,并指定字符串长度,例如:

代码如下:

$pdo -> bindParam(':clobData', $clobData, PDO::PARAM_STR,strlen($clobData));

2. 读取数据

PDO取出的CLOB字段值在该字段不为空时是资源标识符,为空时为空字符串,取数据方法如下

代码如下:

$arr = $pdo -> fetch();
is_resource($arr['clob']) && $arr['clob'] =stream_get_contents($arr['clob']);

希望本文所述对大家的PHP程序设计有所帮助。
