使用Php / Ajax Oracle从Blob读取

Question

I am a newbie to PHP development. 我是PHP开发的新手。 I want to fetch pdf documents stored in a blob column and display them in href on different pages of my website. 我想获取存储在blob列中的pdf文档，并在我网站的不同页面上的href显示它们。 But the problem is it shows adobe reader error that says: 但是问题在于它显示Adobe Reader错误，提示：

"The PDF Document cannot be displayed correctly" “ PDF文档无法正确显示”

So far (for the sake of simplicity) I have this: 到目前为止（为简单起见），我有以下内容：

<html>
<head>
<body>

<a href = "readMe.php?id=21">Click here!</a>

</body> 
</head>
</html>

PHP code: PHP代码：

<?php
session_start();

$id = $_GET[id];
$conn = OCILogon("abc","abc","abcserver");

$qry = "select blob_file,doc_name from doc_data where ID =".$id;

$stmt = ociparse ($conn,$qry);

OCIDefineByName($stmt,"BLOB_FILE",$blobFile);
OCIDefineByName($stmt,"DOC_NAME",$blobFileName);
OCIExecute($stmt);

while ($rowResult = OCIFetch($stmt))
{
if($rowResult != null){

$a = $rowResult[0];

}
}
header('Content-type: application/pdf'); 
header('Content-disposition: inline;filename='.$blobFileName.'.pdf'); 
echo $a;

?>

Please tell me where I am going wrong? 请告诉我我要去哪里错了？

Answer 1

Don't know why it makes sense, but I replaced the code from: 不知道为什么有意义，但是我替换了以下代码：

while ($rowResult = OCIFetch($stmt))
{
if($rowResult != null){
$a = $rowResult[0];
}

to this: 对此：

while ( $row = OCI_Fetch_Array($stmt, OCI_ASSOC+OCI_RETURN_LOBS) ) 
{
$a = $row['BLOB_FILE'];
}

Keeping the rest of the code same and now it displays all pdf's in the browser beautifully. 保持其余代码不变，现在它可以在浏览器中漂亮地显示所有pdf。 Chow :) 周:)
