php 连接oracle插入多张图片的方法

　　php连接oracle数据库的时候，其查询、更新、删除数据和MySQL类似，但是增加数据、特别是图片的时候就很不一样，这里面涉及到要创建一个blob对象，用blod对象去保存php图片，下面是当插入多张图片的时候的写法，直接上代码：

$conn = oci_connect('RGSUser', 'mycompany', '(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = **.**.**.**(IP地址))(PORT = 1521)))(CONNECT_DATA = (SERVICE_NAME = orcl)))', 'utf8');

 $sql = $sql."ID,"; $value = $value."sys_guid(),";
 $sql = $sql."LSH,"; $value = $value.":lsh".",";
 $sql = $sql."VERFYTYPE,"; $value = $value.":verfytype".",";
 $sql = $sql."IDENTIFICATIONNO,"; $value = $value.":id".",";
 $sql = $sql."REALNAME,"; $value = $value.":realname".",";
 $sql = $sql."PHONE,"; $value = $value.":phone".",";
 $sql = $sql."BINDDRIVELICENSE,"; if ($dabh!=null) { $value = $value."1,"; }else{ $value = $value."0,";}
 $sql = $sql."PICDATAIDENTIFACE,"; $value = $value."EMPTY_BLOB(),";
 $sql = $sql."PICDATAIDENTIFACEWATERMARK,"; $value =  $value."EMPTY_BLOB(),";
 $sql = $sql."PICDATAIDENTIBACK,"; $value = $value."EMPTY_BLOB(),";
 $sql = $sql."PICDATAIDENTIBACKWATERMARK,"; $value = $value."EMPTY_BLOB(),";
 $sql = $sql."PICDATAIDENTIPERSON,"; $value = $value."EMPTY_BLOB(),";
 $sql = $sql."PICDATAIDENTIPERSONWATERMARK,"; $value =   $value."EMPTY_BLOB(),";
 $sql = $sql."ISLOCK) VALUES ("; $value = $value."0".")";

//这里很重要，相当于保存图片的字段指定了对应的标签
 $sql = $sql.$value." RETURNING PICDATAIDENTIFACE,PICDATAIDENTIFACEWATERMARK,PICDATAIDENTIBACK,PICDATAIDENTIBACKWATERMARK,PICDATAIDENTIPERSON,PICDATAIDENTIPERSONWATERMARK,PICDATAVEHICLELIC,PICDATAVEHICLELICWATERMARK INTO :PICDATAIDENTIFACE,:PICDATAIDENTIFACEWATERMARK,:PICDATAIDENTIBACK,:PICDATAIDENTIBACKWATERMARK,:PICDATAIDENTIPERSON,:PICDATAIDENTIPERSONWATERMARK,:PICDATAVEHICLELIC,:PICDATAVEHICLELICWATERMARK";

/*
上面的拼接语句比较复杂，下面是拼接之后的结果
