使用fopen / fwrite / fclose（php）无法在mysql中保存xml文件内容[关闭]

So I'm writing an XML file in php with fopen/fwrite/fclose and then attempting to save that information into a MySQL database BLOB field; however, I'm running into an issue where after saving the information into MySQL, all the file contains is "Resource id #33" and none of the information that I was trying to save.

$blahXMLFile = fopen($_POST['scenBlahNewName'].".xml","wb");
fwrite($blahXMLFile, "<?xml version='1.0' encoding='UTF-8' standalone='yes'?>");
fwrite($blahXMLFile, "<Blah>");
fwrite($blahXMLFile, "<Name>");
fwrite($blahXMLFile, $_POST['scenBlahNewName']);
fwrite($blahXMLFile, "</Name>");
fwrite($blahXMLFile, "</Blah>");
fclose($blahXMLFile);

$sql = "INSERT INTO blah (xmlFile) 
                      VALUES ('$blahXMLFile');";

if($conn->query($sql) === TRUE) {
    } else { echo "<script>alert('Error: " . $sql . "<br>" . $conn->error . "');</script>";
        echo "Error: " . $sql . "<br>" . $conn->error;
    } //end else

And then after that I take the $blahXMLFile php variable and try to save it in the BLOB field in my MYSQL database and "Resource id #33" is all that's in the file. This is also the case if I use javascript to alert the php variable.

What am I missing?

EDIT: Trying to use fread here correctly based off of a comment:

$blahXMLResource = fopen($_POST['scenBlahNewName'].".xml","w");
$blahXMLFile = fread($blahXMLResource, filesize($_POST['scenBlahNewName'].".xml")); 

Because that isn't saving a file at all anymore.

Alright, so I got it; after advice from @chris85 I replaced my fopen/fwrite/fclose with file_put_contents (I was using file_get_contents, but that was appending rather than overwriting the files each time).

$blahXMLFile = $_POST['scenBlahNewName'].".xml";

$blahXMLFileContent = "<?xml version='1.0' encoding='UTF-8' standalone='yes'?>
<Blah xmlns='uri:/mil/tatrc/physiology/datamodel' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xsi:schemaLocation=''>   
    <Name>".$_POST['scenBlahNewName']."</Name>
</Blah>";

file_put_contents($blahXMLFile, $blahXMLFileContent);

echo "<script>alert('".addslashes($blahXMLFileContent)."');</script>";

$blahXMLFileContent is what I eventually put into the MySQL database.
