Remote image file to sqlite blob in PHP?

Question

I have an image file stored on a remote server. I only have HTTP access to the server, so I\'m getting its content using file_get_contents(URL)

I need to store this

Answer 1

Don't do it. Every time you insert binary data into a database, God kills a kitten.
Instead, store that image somewhere in the file system and save the path in your db.

Remember to think of the kittens!

Answer 2

Concatenating data you have no control over in an SQL statement is a very bad idea. For instance the image data may contain a quotation mark that will terminate the string or a backslash that will be interpreted as a control character. Worst someone could build a fake image to injects malicious SQL code in your application.

I suggest you use a prepared statement instead:

$query = $db->prepare("INSERT INTO myTable (myImageBlob) VALUES (?)");
$query->bindParam(1, fopen($filePath, "rb"), PDO::PARAM_LOB);
$query->execute();

Note that by passing PDO::PARAM_LOB to bindParam() you insert the blob's data from a stream. That's why I'm using fopen() instead of file_get_contents()
