How to use BLOB with JSON and PHP?

Question

I have a remote database with MySQL, and I am storing photos of the users of my app on the database as a row of the database with LONGTEXT type.

I transform the phot

Answer 1

Is the slowness coming from json/base64 encoding 100K of data, or from the database hit? Its probably from the encoding, and putting the files in the file system (as everyone in the comments is crying), on a small scale, is not going to make a bit of difference.

Do some measurements on the different parts of the operation, and try to pinpoint why its slow. I don't know how else you'd get an image blob into a json encoded string without base64, i suppose you could try and escape everything, which might be just as slow, and hope the parser doesn't choke on it.

Are you using the json_encode function in php, or manually building the string? Try building it manually. Are you base64 encoding raw data from the database, or is it encoded before its stored, you should encode it before its stored to save time when outputting.
