[PHP] PHP MySQL Problem
Good morning friends, I have a script that collects data from a form and puts together a mysql query to search a database. Now, everything worked fine until I added a few new form fields... now the $_POST['var'] don't reach the script... I have about 20 to 25 form fields which are all taken into the query... Now my question: is there a limit in the fields that I can use in the query string to query the database? Somehow the script doesn't even output the value of the POST data anymore... been using this stuff for years now, and i'm feeling really silly at the moment. I'd appreciate any help. Cheers!

Re: [PHP] PHP MySQL Problem
Right, here we go... this page has about 1000 lines of code, so here the
relevant stuff.
$s_query = SELECT * FROM database WHERE
kategorie LIKE '$s_cat' AND
marke LIKE '$s_marke' AND
leistung_kw = '$kw_von' AND leistung_kw = '$kw_bis' AND
preis = '$s_preis_von' AND
preis = '$s_preis_bis'.$checkboxes.$sort_str;
I get the $checkboxes from the POST checkboxes, which looks like this (an
example):
$kraftstoffart = $_POST['fueltype'];
if($kraftstoffart == 3) {
$checkboxes .= ;
}elseif($kraftstoffart == 2) {
$checkboxes .= AND kraftstoffart = '2';
}elseif($kraftstoffart == 1) {
$checkboxes .= AND kraftstoffart = '1';
}
and the $sort_str comes in like
$sort_by = $_POST['sort_by'];
$desc_asc = $_POST['desc_asc'];
$sort_str = ORDER BY .$sort_by. .$desc_asc;
The query then just goes like
$do_q = mysql_query($s_query) or die(mysql_error());
and that's it... no errors shown, just the regular output which I had
before I put the new fields in there. So no changes to what I've had
before... but there should be changes *g*
I hope anybody can find some sense in what I'm writing here... hardly makes
sense to me :oP
Cheers!

actually there seems to be no problem with your query (besides that you
should check posted values first in order to avoid SQL injection)
you said in your first letter that $_POST['var'] don't reach the
script - I would guess the relevant part is not the query but rather
the form itself...

[PHP] Re: Uploading Files Should I use MySQL or Server for storage?
[EMAIL PROTECTED] wrote: I am in the process of adding a part to my website which would include pictures, pdf files, txt files, and excel files. The files sizes could be anywhere on average of 100k to 2mb. Do you think I should be uploading the files to a MySQL database or to my server? I have head that there are pros and cons to both, but have never really received a definitive answer that helps much. I appreciate all your opinions on the pros and cons of both. benc11, I store most of my data in both. when i do image processing i usually upload the image, store the original in the database, process the image into its subsequent sizes or resolutions and store them on the file system. If the images get lost on the file system or my application can not find them I have the original stored in the db for reprocessing. I store files other than images, PDF DOC etc... in the database and on the file system. i serve the document from the file system because regardless of the thread of conversation it is in my experience that 99% of the time it is faster to do so. if its not found i know i have a fall back in that it is also stored in the database so i serve that. Sure my method uses more storage space, but I sleep at night knowing I have added redundancy.

Re: [PHP] PHP MySQL Problem
I thought so, too. But the part where it receives the data is this:
$s_marke = $_POST['marke'];
$s_modell = $_POST['modell'];
$s_preis_von = $_POST['preis_von'];
$s_preis_bis = $_POST['preis_bis'];
$s_mileage_von = $_POST['mileage_from'];
$s_mileage_bis = $_POST['mileage_to'];
$s_ez_von = $_POST['ez_from'];
$s_ez_bis = $_POST['ez_bis'];
$s_search_text = $_POST['search_text'];
$s_cat = $_POST['cat'];
$kw_von = $_POST['kw_von'];
$kw_bis = $_POST['kw_bis'];
(part of it)
And this is the relevant part of the form
select name=kw_von
option selected=selected value=0***/option
option value=/60/option
option value=/75/option
option value=/90/option
option value=8181/110/option
option value=9292/125/option
option value=110110/150/option
option value=147147/200/option
option value=184184/250/option
option value=220220/300/option
option value=257257/350/option
/select
The funny thing is that all vars are being received except for the last two:
$kw_von = $_POST['kw_von'];
$kw_bis = $_POST['kw_bis'];
I am s stuck here, it ain't even funny anymore *g* And my boss is, of

[PHP] When does PHP free-up memory allocated to it?
Hi, Quick question - does anyone know when PHP actually frees allocated memory during the process of a script? I'm using 5.2.2. For example I see the following results when profiling: Memory: 256 KB Load a 1024x768 JPEG (via GD) Memory: 4 MB Create thumbnail (via GD) Memory: 5.2 MB Destroy original image resource (imagedestroy) Memory: 5.2 MB I would have expected (or rather, hoped) that the memory use would have dropped down quite dramatically after destroying the image resource that was using up nearly 4MB of memory, but it didn't seem to change. Is this a limitation of the memory_get_usage(true) function, or does imagedestroy not actually do what it implies?

JV EEPROM, using a command that returns two bytes at a time, and write
JV similar strings using a similar command. For example, to read the first
JV two bytes of one such string beginning at address 0x484, I would send:
JV 04 84 00 00 BB
JV Here's the code I've written so far:
JV $string = 1; //which of 200 strings I want to read
JV $base = pack(H*,dechex((($string-1)*hexdec(0x1a))+hexdec(0x484)));
JV //calculate the base address of the string (the first starts at 0x484)
JV for($i=0;$i 13;$i++) { //iterate 13 times (26 bytes / 2 bytes at a time)
JV dio_write($serial,$base.\x00\x00\xbb,5); //send the command
JV $output[] = dio_read($serial,1); // read first byte
JV $output[] = dio_read($serial,1); // read second byte
JV $base = pack(H*,dechex(hexdec(bin2hex($base))+2)); //increment address
JV }
JV There are two things wrong with this. First, the final line isn't doing
JV what it's supposed to. Instead of adding 2 to the value of $base each
JV time, It's producing a pattern like this:
JV 0x484, 0x486, 0x73, 0x73, 0x73, 0x488, 0x48a, 0x48c, 0x48e, 0x490, 0x74,
JV 0x74, 0x74

[PHP] Timezone DB update frequency
I am responsible for development of a product using PHP, which is distributed as a component of the product. How often does the timezone DB (php_timezonedb.dll) actually *need* to be updated? We would be responsible for this task via product updates so need to know if the default DB shipped with PHP will become unsuitable and when / how often. Thanks, --rob

[PHP] [Linux] PHP and SQL Server
Hi,
I'd like to connect to SQL Server (it is MSDE from SQL Server 2000) from
PHP.
My system is Debian.
I've installed FreeTDS and some dependencies...
Here is my /etc/freetds/freetds.conf :
[global]
# TDS protocol version
tds version = 4.2
[etemptation]
host = 10.21.2.203
port = 1433
tds version = 8.0
Then, my /etc/odbc.ini :
[etemptation]
Description = TDS MSSQL Server
Driver = /usr/lib/odbc/libtdsodbc.so
Server = 10.21.2.203
Database = etemptation
Port = 1433
TDS_Version = 8.0
And, my /etc/odbcinst.ini :
[FreeTDS]
Description = TDS driver (Sybase/MS SQL)
Driver = /usr/lib/odbc/libtdsodbc.so
Setup = /usr/lib/odbc/libtdsS.so
CPTimeout = 5
CPReuse = 5
UsageCount = 1
My PHP test page is :
?php
$cnx = odbc_connect(etemptation, idep, password);
if(!$cnx) {
echo 'problem connexion';
}
else{
echo 'connexion OK';
$sql =SELECT * from HOPPOIN;
$rs = odbc_exec($cnx,$sql);
while(odbc_fetch_row($rs)) {
}
odbc_free_result($rs);
odbc_close($cnx);
echo 'connexion fermee';
}
?
But the result is :
Warning: odbc_connect() [function.odbc-connect]: SQL error:
[unixODBC][FreeTDS][SQL Server]Unable to connect to data source, SQL
state S1000 in SQLConnect in /home/david.bercot/Internet/test_mssql.php
on line 2 problem connexion
I've also tried in a shell :
p3010-ac-nantes:/home/david.bercot/Internet# isql -v etemptation
src/tds/login.c: tds_connect: 10.21.2.203:1433: Connexion refusée
[S1000][unixODBC][FreeTDS][SQL Server]Unable to connect to data source
[08S01][unixODBC][FreeTDS][SQL Server]Server is unavailable or does not
exist. [ISQL]ERROR: Could not SQLConnect
Do you have any idea for my problem ?
Thank you very much.
David.

On Mon, May 21, 2007 4:23 am, Richard Davey wrote: Quick question - does anyone know when PHP actually frees allocated memory during the process of a script? When it can be sure that a variable is no longer needed. Specifically, when the .refcount of a zval turns to 0. I'm using 5.2.2. For example I see the following results when profiling: Memory: 256 KB Load a 1024x768 JPEG (via GD) Memory: 4 MB Create thumbnail (via GD) Memory: 5.2 MB Destroy original image resource (imagedestroy) Try unset($image) as well, so PHP knows you no longer need access to that variable that was holding all that stuff... Memory: 5.2 MB I would have expected (or rather, hoped) that the memory use would have dropped down quite dramatically after destroying the image resource that was using up nearly 4MB of memory, but it didn't seem to change. How are you measuring this? What version of PHP? The Memory Manager changed over the course of time. I'm also not at all sure that you *can* measure it as precisely as you are trying to do. Is this a limitation of the memory_get_usage(true) function, or does imagedestroy not actually do what it implies? Almost for sure imagedestroy() does what it should -- and GD frees up the internal memory structures for that image. PHP still has a variable sitting around pointing to that resource, however, and you may need to notify PHP through unset() that you are done with it. That said: PHP doesn't really allocate that 5.2M of RAM. GD does. PHP may not be able to tell you accurately about what GD is doing internally -- but it's probably not *really* losing that 5.2M or you'd hear an awful lot more screaming about it from all quarters. :-) -- Some people have a gift link here.

There are PHP sites handling millions of impressions daily, and that's not even all that tricky, as I understand it... What you might consider, if you decide to go down this path at all, is to write it in PHP with an eye to developing a custom PHP extension by re-writing your PHP code in C once you've worked out all the details. This would give you the rapid prototyping and flexibility of PHP in the early days, and satisfy any reasonable need for speed after you are suitably crusty to not feel the need to make sudden changes, by just porting the PHP code to C code. Shouldn't be too hard to discipline yourself to only write PHP that you know how to convert to C -- and, really, PHP ends up as byte-code executed by C, so worst-case is you could dig into PHP Internals to figure out what your tricky PHP is doing... -- Some people have a gift link here.
