In what way would this simplify or ease my pain?
The difficulty, it seems to me, is not in retrieving the rows, but
rather how to pass the row data to the variables. And since the number
of rows is variable, I believe that the only way to assign the variables
is by use of a loop? I think I'm beating my head against the wall for
nothing... :-(
I know I'm a newbie (a very lazy and ignorant one, apparently) but I
don't quite understand. Or is there a gain in execution time or resource
usage?

Re: [PHP] Search/Replace in entire database?
Hi Chris, MySQL introduced full - text indexing and searching capabilities back in version 3.23.23. The implementation is straightforward and easy to use — define a FULLTEXT index and use MATCH / AGAINST in the query. Consider this example: CREATE TABLE SOCIAL_EVENT ( EVENT_ID INTEGER UNSIGNED NOT NULL AUTO_INCREMENT, USER_ID INTEGER UNSIGNED NOT NULL, HEADLINE TEXT NOT NULL, EVENT_TEXT TEXT NOT NULL, EVENT_DATE TIMESTAMP NOT NULL, PRIMARY KEY (EVENT_ID), FOREIGN KEY (USER_ID) REFERENCES SOCIAL_USER(USER_ID), FULLTEXT INDEX (HEADLINE, EVENT_TEXT) ) ENGINE=MyISAM DEFAULT CHARACTER SET latin1 COLLATE latin1_general_cs AUTO_INCREMENT=0; Thanks.

Re: [PHP] Re: Search/Replace in entire database?
You can always cheat. Use information_schema or just show databases and show tables and loop through it. Just using information_schema is perfect though i think then you can know or query on column type and save some work.

Re: [PHP] Uniquely identifying an array... as a key to another array
2009/6/15 Eddie Drapkin oorza...@gmail.com: Alright, here's the situation. I'm wrapping memcached, which takes a list of several servers, into a quasi-singleton. In other words, I want only one instance per set of servers, not per server. Assuming I had three memcached servers at localhost, 192.168.1.1 and 192.168.1.2, I wouldn't want one instance per server, but given that there are seven possible permutations of combinations / only one server configuration, MemcacheConnector::$instances could be an array with seven objects. I'm expecting MemcacheConnector::getInstance($array) to take an array formatted like 'server' = 'port'. Thusly, the question then becomes, what's the lightest possible way to store a unique-ish array as the key for MemcacheConnector::$instances? Having MemcacheConnector::getInstance() check for self::$instances[serialize($serverArray)] seems a huge waste of both ram and CPU time. Is there a better way? Why not give each set of servers a name? Surely they're grouped together for a reason, so give that reason a name. -Stuart -- http://stut.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Thanks for any advice you can give me. Regards Chris Payne Chris: The problem you cite is exactly why one should use relational databases. If the people you are working for had done that, then you would have only to edit one table. The process works like this -- you have a product table that has an unique id with other information about each product, such as its name. However, every table that references that product does so via the product's id and not the product's name. As such, each look-up for the product name requires first to know the product's id and then pull out the name associated with that id. In any event, a little more work at the start saves tons later.

You asked for easier. In this way the data is assigned to a usable
variable right out of the gate and that is an array variable. You can
actually use it with either mysql_fetch_array or mysql_fetch_row.
Here is your query;
$sql = SELECT first_name, last_name, book_author.ordinal
FROM author, book_author
WHERE book_author.bookID = $idIN book_author.authID = author.id
ORDER BY ordinal;
You need not declare another array, but do it this way instead;
if ($results = mysql_query($sql, $db)) {
while ( $row = mysql_fetch_array($results, MYSQL_ASSOC) ) {
echo $row['first_name'];
echo $row['last_name'];
etcetera.
}
}

well to linear alterations ($varIn, $var2IN, $var3IN... etc... so $i=0

change that to $var1IN... and then figure out how to do $var.$i.IN ... I
already tried, but don't seem to have it right

Well, I shouldn't say it, but laziness is a characteristic of
intelligence: why do more than you have to when you can be doing
something else. Actually, I am anything but lazy, I spend innumerable
hours trying to understand what all this coding is about... searching
the web and rummaging (and I do mean rummaging) in all the lists and
posts ... but just going through 20 or 30 listings out of more than
20,000 is already taxing... much easier to ask on the list... if someone
can understand my fuzzy questions, they may find the grace and
generosity to take pity on the ignoramus... ;-)
And I enjoy the ribbing and the humour ... it's a really very nice list!

I am having difficulties figuring out how enter retrieved data into a dropdown box for editing. Here's a snippet: ...snip select name=categoriesIN[] multiple size=8 option value=1Civilization/option option value=2Monuments, Temples amp; Tombs/option option value=3Pharaohs and Queens/option... snip As I understand it, I need to put an array ( $categoriesIN[] ) somewhere in the above code... or do I need to insert a series of value selected fields for the values? The closest thing to what I need, seems to be in this post: http://www.hpfreaks.com/forums/index.php?topic=165215 But it doesn't appear too inviting... not sure if they ever got it to work... -- Hervé Kempf: Pour sauver la planète, sortez du capitalisme. - Phil Jourdan --- p...@ptahhotep.com http://www.ptahhotep.com http://www.chiccantine.com/andypantry.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] fopen() on a network share?
Extra info, in case needed: my code says
fopen('\\servername\sharename\folder\file.xml', 'w');
and it returns Failed to open stream, no such file or directory.
I've verified that the PHP machine does have unrestricted permissions
to that share and to the directory. Thanks.

As I remember, you either have to double slash or use the other slash.
servername\\sharename\\folder\\file.xml
or
//servername/sharename/folder/file.xml

I think 'servername\sharename\folder\file.xml' will work if you're
using single quotes around the string. The only slashes that would
need escaped are the first two since the first slash in '\\' escapes
the second.

[PHP] I2C, sending a binary byte with fwrite
Hi, I'm working on a interface between the I2C Bus (Hardware) and PHP - to use the PHP as webinterface to control an I2C Device. The bus is mounted as: /dev/i2c8_aux - and works opening the bus with $fd=fopen (/dev/i2c8_aux, w (r+) (r+b) (wb))is successfull setting the address of the slave device (0xB0 (=0x58) and the register (between 0-15) works fseek($fd, 0x5801) (accessing register 01) Now - the things that doesn't work: writting into the register I'd like to write a value between 0-255 (0x00 and 0xff) e.g into register 1 (the one from above) - (0 = turn left, 128=stop, 255=turn right) I can only write one (1) byte into the register, and fwrite uses strings. $data = 128 $rslt = ($fd, $data, 1) would write 3bytes. So, what I need is a way to convert any value between 0 and 255 into a string with one byte, e.g 0xff = (with strlen($data) == 1) I tried it with: chr(255) - not successfull pack(H and h, 0xff) - not successfull decbin(255) - without success and many more. Any advice, suggestion, experience? Thanks! Tobias
