使用php将pdf远程文件存储在postgres DB中

Question

I have little pdf (or txt, odt, doc) file to be store in Postgres DB with php. I use this php functions to read file:

$fp = fopen($name, 'rb');

$content = fread($fp, filesize($name));

$content = addslashes($content);

fclose($fp);

and then try to store in db:

$sql = "insert into Table(column) values ('$content'::bytea)";

$result = @pg_query($sql);

"column" is bytea type.

When I execute the script with pdf file, I get the follow error:

ERROR: invalid byte sequence for encoding "UTF8": 0xe2e3cf HINT: This error can also happen if the byte sequence does not match the encoding expected by the server, which is controlled by "client_encoding".

When I execute the script with doc file, I get the follow error:

ERROR: invalid input syntax for type bytea

When I execute the script with txt file, NO error:

What's wrong and what is the proper way to store files?

Have you tried using pg_escape_string instead of addslashes? http://www.php.net/manual/en/function.pg-escape-string.php
