PHP上传模块限制文件大小> 2 KB

我有用HTML/PHP编写的上传文件页面。该文件的内容存储在Oracle表的Blob列中。问题是它只上传小于2 KB的文件，而不是较大的文件。下面的代码。PHP上传模块限制文件大小> 2 KB

问题：

代码只对文件大小< 2 KB。

所有这些参数都大于2KB。

PHP：upload_max_filesize的2M
PHP：8M的post_max_size
PHP：max_input_time设置60

HTML：

Please specify your file: 

<form method="post" id = "myForm" name = "myForm" enctype="multipart/form-data" target="upload_target" onsubmit="startUpload();"> 
<p style = "text-align:center"><img align = 'middle' src = "logo.jpg" width="50%" height="100"></img></p> 

<h3 align = 'center'><font color = 'orange'><u>Text File Upload</u></font></h3> 
<div class = "center"> 
<select id = "selectPol" name = "selectPol"required > 
<option value="">Please select file type</option> 
<option value="choiceone">Choice One</option> 
<option value="choicetwo">Choice Two</option> 
</select> 
</div> 


<div class="center" id = "formDiv"> 

<br></br><input type="file" name="datafile" id = "datafile" /> 

<p> 
<input type="submit" id = "save" name = "save" value="Upload"/> 
<input type="reset" value="Reset" /> 
</p> 

<p style = "text-align:center" id="result"></p> 
</div> 
<div id = "f1_upload_process" name = "f1_upload_process" style = "text-align:center; display: none;"> 
<span style = "text-align:center"><font color = "orange"><b>Uploading. Please wait...</b></font></span><br> 
<img align = 'middle' src = "progress_bar.gif"></img> 
</div> 
</form> 
<iframe id="upload_target" name="upload_target" src="#" style="width:0;height:0;border:0px solid #fff;"></iframe>     
</body> 
</html>

PHP：

if(isset($_POST['save']) && $_FILES['datafile']['size'] > 0) 
{ 
$fileName = $_FILES['datafile']['name']; 
$fileSize = $_FILES['datafile']['size']; 
$tmpName = $_FILES['datafile']['tmp_name']; 
$fileType = $_FILES['datafile']['type']; 
$fp = fopen($tmpName, 'r'); 
$content = fread($fp, filesize($tmpName)); 
$content = addslashes($content); 
fclose($fp); 
$conn = OCILOGON("myDB","myDB","MYSERVER"); 
$qry = "INSERT INTO FilesTable (date_input,file_name,File_CONTENT) VALUES (SYSDATE,'$fileName',utl_raw.cast_to_raw('$content'))"; 


$stmt = OCIparse($conn,$qry); 
ociexecute($stmt); 

$result = oci_num_rows($stmt);

我没有用'oci_ *'lib中的经验但是它肯定看起来你很容易受到SQL注入你的'$ fileName'变量。 –

你可以将更多的表单放入源代码中吗？例如它是否包含文件输入前的MAX_FILE_SIZE隐藏字段？ – GordonM

问题不在于PHP文件大小，问题在于utl_raw.cast_to_raw('$content')在查询中。当在Blob列中插入2KB以上时，它有一个限制。

取代我的SQL代码：

$qry = "INSERT INTO FilesTable (date_input,file_name,file_content) VALUES (SYSDATE,'$fileName',empty_blob()) RETURNING file_content INTO :file_content"; 
$stmt = OCIparse($conn,$qry); 
$blob = ocinewdescriptor($conn, OCI_D_LOB); 
ocibindbyname($stmt, ":file_content", $blob, -1, OCI_B_BLOB); 
ociexecute($stmt); 
ocicommit($conn); 
ocifreestatement($stmt);

而且它的工作原理:)
