[PHP] breaking a string into chunks
Hi, all -- Now it's my turn to ask a simple question, or one that sure sounds like it should be... I have a 14-char date string like 20030917181909 and I need to break it into its component parts for a more readable 2003-09-17 18:19:09 view. How can I do that? Do I really need to call substr half a dozen times?(!?) I tried unpack() but all I ended up getting was an array with one entry (sometimes with a very strange-looking key).

In perl I'd do something like:
$time =~ m/(\d){4}(\d){2}(\d){2}(\d){2}(\d){2}(\d){2}/;
$ntime = $1-$2-$3 $4:$5:$6;
I think php can do that with preg_match, using an array to hold the matches.
As the other poster said, if this is mysql, let mysql do the work for you :)

you can call preg_match, and only once David T-G wrote: Hi, all -- Now it's my turn to ask a simple question, or one that sure sounds like it should be...

Yep.

Well, I would, but this has already been pulled out by another call for
its own use. I'm being clever and reusing the data I have rather than
making an extra DB query. Gee, see how much time it's saving me? ;-)
It also happens that I don't know how to have mysql format it for me as I
would like were I to make said second query -- but that's only temporary.
Thanks HAND

RE: [PHP] breaking a string into chunks
Make your own function, for example:
function transformDate($format,$str) {
$d = Array();
for($i=0;$istrlen($str);$i+=2) { $d[]=substr($str,$i,2); }
return
date($format,mktime($d[4],$d[5],$d[6],$d[2],$d[3],$d[0]$d[1]));
}
print transformDate(Y-m-d H:i:s,20030917181909);
So, you can change to any format with the first arg. of the function.

In perl I'd do something like:
$time =~ m/(\d){4}(\d){2}(\d){2}(\d){2}(\d){2}(\d){2}/;
$ntime = $1-$2-$3 $4:$5:$6;
preg_match('/(\d){4}(\d){2}(\d){2}(\d){2}(\d){2}(\d){2}/', $time, $m);
Then $m is an array where the indexes
$m[0] = the matched string
$m[1] = first ()
$m[2] = second ()
...
I think php can do that with preg_match, using an array to hold the matches.
As the other poster said, if this is mysql, let mysql do the work for you :)
I suggest this also. Or use the mysql unixtimestamp function to
return a uts and format the output with php.
In general most of my timestamp fields, in my tables, I create as an
INT then just store the Unix timestamp in there. Makes things
easier when trying to display things.
