[PHP-DB] var_dump and sizeof database entry?
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.

If someone does answer, no second email needed. No harm, no foul. 2) No, the confidentiality notice is not *necessary* according to a strict definition. However, many people that work in the 'real world' actually have *no* control over this as it is automagically added to the end of every email leaving their email servers, **regardless** of user-settings. This is server-side code, not client-side. No harm, no foul. And yes, as you can probably tell by now, I don't have a problem with top posting either. I apologize if I have offended someone.

Re: [PHP-DB] Question on CURDATE()
Micah, Oh, my bad. I was trying to remember how I did something like this before, stringing together a lot of WHEREs. You're right, though, it wasn't WHERE, it was OR. Rich, I think you need OR instead of AND, OR else I'm just totally out to lunch tonight: SELECT * FROM WEEKS WHERE BEGIN = CURDATE() OR END = CURDATE(); The syntax error is that something cannot be = AND = the same thing at the same time! I have had this problem before in the past. You say to yourself, well, I need all of the records, so that intuitively makes you choose AND when in SQL it should technically be OR (you want the records that are true for each of these operators separately, NOT at the same time, which for most records is impossible). Also, you may want to take away one of the = signs, or you may get something = to CURDATE() twice (not sure how SQL handles this). Maybe try (taking out one of the =): SELECT * FROM WEEKS WHERE BEGIN = CURDATE() OR END CURDATE(); Maybe it's just late over here. Has anyone else run into this same thing?

Re: [PHP-DB] Storing an array on a table?
Yes, this has been mentioned in this thread. But with serialize/ unserialize, you can run into other problems that may be more confusing/difficult to troubleshoot. e.g.: http://www.php.net/serialize As you can see, the original array : $arr[20041001103319] = test after serialize/unserialize is: $arr[683700183] = test yepp, and i can explain it. the internal compiler of php does not hit anys rule wich foces him to make that number a string during serialisation. since it becomes an integer and php supports 32bit interger not arbitary bitwidth this is what happens: 20041001103319 equals hexadecimal: 0x123A28C06FD7h if you cut away the frontpart cutting down to 32bis, you get: 0x28C06FD7h wich equals 683700183. For simple arrays, I prefer storing everything as a simple imploded string. YMMV. Jordan On Sep 1, 2005, at 10:18 AM, [EMAIL PROTECTED] tg- [EMAIL PROTECTED] wrote: Sorry, didn't catch this thread from the beginning, but did anyone recommend trying the serialize() and unserialize() commands? They'll convert the array to a block of text that can be stored, retrieved and unserialized. My gut instinct is that if you're trying to store any array in a database, you may not have thought through your design very well. BUT.. I also know that there are cases where you might want to (I've actually done it before... being lazy in that case..hah) so dont take that as criticism, just wondering if there's a more right way to do it. If that's what you need to do though, definitely check out serialize (unless someone knows something I don't). Serialize() should do essentially what's being proposed below, just without having to figure out what string may not be in your array. good luck! -TG = = = Original message = = = if you just have a simple array with automatic numeric keys and text you could just implode the data to a string with a separator not found in your data: $dataArray = array(hello, goodbye, etc.); $storable = implode(, $dataArray); // $storable becomes hellogoodbyeetc. //then, use explode to get the original array back again $dataArray = explode(, $storable); you could use a similar technique if you want to put the keys in as well, albeit slightly more complicated (e.g. use to separate each element in the array and || to separate each key from its value). Just find a divider you know your data will not contain, such as a pipe: |. This has worked well for me.

strange, with your code, mine cuts out at 49 significant digits:

the result is the same as 16!!!

precision sets the number of significant digits, *NOT* the number of
digits displayed after the decimal point.
If you want to get pi out to 16 decimal places you need a
precision of
*17* because the beginning 3 is a significant digit.
Your code does exactly this, displaying pi with 15 decimal places.

Hi there everyone,

$video_link = $row[video_link];
$video_thumbnail = $row[video_thumbname];
$video_title = $row[video_title];
$video_description = $row[video_description];
};
Now I’ll be shifting through my MySQL array 6 items at a time,
what I’d
LIKE to be able to do is store each item in a number string on
each pass.
In other words, the first loop would see $id being called
something like
$id1, the second pass in the loop it would be $id2 and so on.
I THOUGHT I could do this by putting a $count ++ in the loop and
then doing
something like $id$count or something like $id.$count but neither
worked,
this may sound odd but I REALLY need to be able to do this so how
can I
name a string that has to contain the data from a row successively
higher
on each loop so that it doesn’t overwrite the data on the previous
loop?
I have 6 items on the page so I can hardcode ?=$id1? for item 1 and
?=$id2? for item 2 etc …. But with the layout of the page being
able to
do it THIS way would be MUCH better than having to set the table
itself up
to handle it.
Any help on this (Probably very easy) but annoying problem would
be REALLY
appreciated ;-)

i am talking about individual records, not putting all records into a very long string, if that's what you are saying. i know people routinely use millions of records... but how about billions or more?

Here's the matching answer: The number of records any database can hold matches the length of a piece of string. Seriously - do some homework, visit the host sites and read the specs. A lot depends on what you intend to store. As for interacting well - push the string.
