I dig many google suggestion to find a working solution but I got nothing.

What is the right way to insert a file on a Oracle LOB column with PDO?

I'm always getting a data length of 0 for the content of the LOB in the database. I saw many forum suggesting to use RETURNING in the query with EMPTY_LOB(), even then my LOB is always empty. This is what I have right now (my code is customizable, I gave you just the minimum). I push on arrayOfBind in the same time that I build my variable. Every parameter is in the correct order. I can see my result in my database viewer but LOB always empty.

$sql = "INSERT INTO {$tableName} ({$strCol}) VALUES ({$strBind}) RETURNING {$fileAttr} INTO ?";

 $stmt = $connection->prepare($sql);

 foreach($arrayOfBind as $binding){
    $stmt->bindParam($binding[0], $binding[1], $binding[2]); 


I try too to insert an EMPTYLOB() first and after than execute and UPDATE for the LOB, nothing different on the result. If I do streamget_contents on my file, I saw the data. fileSize give me the correct lenght of the file. My other database columns are filled correctly. (size, mime, name)

Help will be appreciate.

I try the two kinds of binding, question mark and :MYVAR, same result...

For your info my database info:

Oracle Database 12c Enterprise Edition Release - 64bit Production

PDO infos:

PDO support enabled

PDO drivers mysql, odbc, pgsql, ibm, oci

PDO Driver for OCI 8 and later enabled

I'm using PDO::PARAM_LOB for the BLOB binding
