[PHP-DB] Re: mcrypt, postgres, only returning half the data
John A second question to answer, it's not clear from your description --- is the encryption 'breaking' during en-cryption (before it stuffs the value into the database) so that all the data is not even getting into the database? -or- is ir breaking during de-cryption ? Sounds to me like it might be a control character is getting interpreted by PgSQL and cutting off the query. You don't mention - what type field to save the encrypted data??? If there's a blob or binary field type (I dunno about PgSQL) try using that field type for encoded data. And - try skipping the add slashes step - what happens??? Good luck, Tom Henry John Starkey wrote: Hello all I'm working on encoding some data going in and decrypting coming out of postgres. I'm adding slashes going in and stripping them coming out. Using BLOWFISH and I've tried several different modes. But each time the data comes out I'm only getting half-decrypted data, it seems to hang at a random spot. The same for each piece of data but random in terms of different for each entry (confusing the issue enough?). I'm using mcrypt_encrypt and mcrypt_decrypt. When I test it on the same page (without going through the database) it decrypts fine, perfect as a matter of fact. But coming out of the DB, the same data is trashed. Is there any special way to send (or abstract) encrypted data into (from) the DB? I've been through the archives and it doesn't look like anyone has posted a problem like this.

[PHP-DB] Re: Show abbreviated article
Try using MySQL to do that right in the query itself (and save the
overhead of retreiving the whole blob then PHP'ing the blob too).
From the MySQL Doc's ;-) RTFM once at least
--
SUBSTRING(str,pos,len)
SUBSTRING(str FROM pos FOR len)
MID(str,pos,len)
Returns a substring len characters long from string str, starting at
position pos. The variant form that uses FROM is ANSI SQL92 syntax.
mysql select SUBSTRING('Quadratically',5,6);
- 'ratica'

For your problem it might look like
$sql = SELECT field1, field2, SUBSTRING(blobfieldname,0,160) FROM
articles where
( BTW I usually assume prox 8 chars per word for something like this so
20 wds x 8 char = 160 chars total BUT you might have lots of esoterica
in there and might want to adjust that ;-) )

Hi,
On my website I want to display some articles, in Slashdot style. The
main page should only display the first 20 words of the article, and
users should be able to click on a link to view the entire article.
The articles are stored in a MySQL database, the body of the article in a
blob-field.
My question is this: how can I select only those first 20 words in the
PHP code?
I hope somebody can help me with this.

[PHP-DB] Re: trash last message ,this ones right I think
Perhaps you could consider using the webserver config (in Apache it would be the httpd.conf file) to do the dirty work. Create and alias (in the /util/ domain) for img that points to the /hdocs/www/img/ location - voila!
