RE: [PHP-DB] var_dump and sizeof database entry?

I would do one of two things here: 1. add a size column to the db and have the image size added when inserting the image 2. run a trash script (either sql if your version support subselects or a little page) to get the size of

    the image and enter it into the size field

Another option is to use select *, (length(image_fiedl)/1024) as Kb from table [where clause] to get the size Bastien

Date: Thu, 5 Jan 2006 16:19:43 -0600 Hello, This is stumping me something awful. I have searched the archive of this mailing list and google and the php and mysql websites with everything i can think of. I have a simple mysql table with some basic columns and a blob column that holds an image file. What I need to get is the size of this image file for use with an rss feed (the enclosure "length" parameter). In the simplest case, I thought I would just read the entire blob into a variable, and then I would be able to get the size of this variable. However, php does not seem to have a function to do this. Inexplicably, the "var_dump" command will actually dump the information I want, but it is very memory inefficient, because I get something like: ["preview"]=> string(17888) "ENTIRE CONTENTS OF BLOB HERE" where all I really want is the 17888 value (for a 17.5 KB file). What I was wondering is if there is a simple way to get this information from mysql directly without having to 1) select the blob column and 2) do a var_dump with output buffering and parsing for the parenthetical file size, which seems very inefficient to me. any insight is greatly appreciated.
