Re: [PHP-DB] Storing an array on a table?
Now you got tow ways. serialize or convernt to a string~ I think string is better~ maybe I'm getting old~ don't like new things like serialize...;-) On 9/1/05, Miguel Guirao <[EMAIL PROTECTED]> wrote: > > > > Hi!! > > I want to store an array into a field on a MySQL table, Is it posible to > save it?

Re: [PHP-DB] Storing an array on a table?
Ahh..thanks Jordan.. sorry I missed that one and thanks for the info. I
assumed serialize was just magic and worked properly. hah. Now I know.
I always thought it was sloppy to use anyway, but in a pinch, it's nice to know
there's an option like that. Imploding does sound better though.

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.:

For simple arrays, I prefer storing everything as a simple imploded
string. YMMV.

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.

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.

If that's what you need to do though, definitely check out

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!

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

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
