Php : Convert a blob into an image file

Question

Is this possible with php and a mysql database to Convert a blob into an image file?

Answer 1

If the BLOB contains the binary data of an image (in a recognizable format like e.g. tiff, png, jpeg, etc), take the content of the BLOB, write it to a file, and voilà... you got an image.

On some strange operation systems you have to give the output file a correspondig extension, so that the image file can be recognised as such.
