[PHP] Re: PHP script problem (with MySQL)
May I sugest that you assemble the SQL statement in a different way? With
such a big conditional, it will slow down the Sql server.
if ($tit != '') $condition .= and tit1 like '%$tit%';
and so on for each search field ...
$sql = Select *, substring(loc1, 1, 3) as loc1 from openart_table where .
substr($condition,4);
'like' conditions are hard on the server, specially if they start with a '%'
since then no indexes can be used. The server can only go through each and
every single record in the database. If, instead, you avoid the % at the
begining, some index information can be used. You might also want to check
FullText searches

Hello,
I need your help about PHP (ver 4.3.1) and MySQL (ver 3.23) database.
I am struggling to customise a database (using left command etc), and am
stuck now.
Please have a brief look at my scripts below.
What I do like to do is to get first 3 letters from loc1 column from
openart_table (MySQL).
And show the data in the follwoing part...
td? echo $row[loc1]; ?br/td
but also I would like to make hyperlinks to jpg files to images/the first
3
letters from loc1.jpg
So it will be something like this...
td
a href=/image/? echo $row[loc1]; ?.jpg? echo $row[loc1];
?/abr
/td
But when I tried, select left (loc1,3) from openart_table where..
doesnt work properly.
I do not want to destroy anything for the rest of the table.
I need all data from tit1, pub1, id1, and ref1 in each column.
Could you show me a script example?
Could you help me, please? Thank you.

I think that in your database it is : substring(loc, 1, 3) as loc1 Anyway, the error is not where you are getting the message, the query failed and this you don't have a valid resource to ask the number of rows or do anything else.

Why not try selecting both the short and the full values of loc1 from

If the user's computer clock is way out of whack, and you are setting a
cookie to expire in 1 hour, you're likely to have problems...
Though *maybe* browsers account for this by comparing your Date: header
and your clock time, and ignore the user clock.
For sure, though, *some* versions of IE will *NOT* work when you set a
Cookie time, but not a path.
That's because the Microsoft engineers mis-read the Cookie spec (on
purpose perhaps) and require *both* time and path, or neither, but not
just path.

Don't know ; Don't care.
You should never loop through so many things in PHP that it matters in the
first place :-)
I read a few days ago somewhere on php.net that foreach() is the
recommended (by php devs) way of iterating over arrays
[shrug]
That's probably because they're tired of people not understanding the
internal pointer array, and asking FAQs about it. Or maybe not. Ask them
why they prefer it. I sure don't know.
also, compare these 2 lines:
while (list(, $idcat) = each($idcats)){ /* ... */ }
foreach ($idcats as $idcat){ /* ... */ }
now its seems to me that the foreach version is 'up' 2 function calls
None of those are function calls.
They are all language constructs. Okay, each() *might* be a function...
I'm not sure how much difference there is in the number of language
constructs used, nor if they are even comparable in sheer numbers the way
functions are.
ah yes, lang constructs rather than function calls.
foreach is probably slower, I think, because it creates a *copy* of the
array to work on, so it won't mess up the original and its internal
pointer.
unless I'm mistaken its a copy-on-change, so unless you are changing the
the array inside the loop you don't suffer the actuall copy penalty - can anyone
knowledgable on php internals confirm or deny this?
actually now I think of it you can use references in a foreach statement:
php -r '
$arr = array(1,2,3);
foreach($arr as $k = $v) {
$v++;
}
var_dump($arr);
'
which suggests that a copy is not (always?) being made...
Again, with 200 bytes, you are wasting your time to worry about any of this.
true, It's purely a theoretical interest - deeper understanding is alway
nice :-)
...its not even my 200 bytes we're talking about ;-)
on the while loop, all else being equal the foreach loop has to be faster
(given that calling functions is relatively very expensive)...
or is foreach() _really_ heavy when compared to while()?
Why don't you just benchmark it on your own machine and find out?
because I don't have the skills to write a test/benchmark that I _know_ is
kosher (and not skewed by a million of my misconceptions, besides I run so much
stuff on my machine that speed can be severely affected by things like
apache or firebird running in the background
that and I lazy ;-) (or I just don't care enough to invest time investigating
this)
not that I care too much, I find foreach() more pleasing to the eye and
there is
less to type (in the given example).
I'm an old dog, and I don't quite understand for sure how this new-fangled
foreach thingie works. I'd spend more time looking it up and reading
about it than just typing what I *know* works. [shrug]

[PHP] explode a string
Sorry jocham, for you getting this twice.
I'd assume foreach is recommended because it lends to more readable
code. More readable code, is generally considered better code.
Personally I'd disagree and use while( list() = each() ), because it
doesn't create a copy of the array in memory, especially for the
array. If you're dealing with an array where the elements are large,
or multi-dimentional, you may want to consider a different approach,
such as assigning by reference, like:
for($keys = array_keys($sample_array); $key = each($keys), $val =
$sample_array[$key]; )
but that is very ugly untested code(and I'm drunk), so I wouldn't
recommend you copy n paste it.
besides for the sake of 200 bytes, with an average of around 5

You should never loop through so many things in PHP that it matters in the
first place :-)
I read a few days ago somewhere on php.net that foreach() is the
recommended (by php devs) way of iterating over arrays
[shrug]
That's probably because they're tired of people not understanding the
internal pointer array, and asking FAQs about it. Or maybe not. Ask them
why they prefer it. I sure don't know.
also, compare these 2 lines:
while (list(, $idcat) = each($idcats)){ /* ... */ }
foreach ($idcats as $idcat){ /* ... */ }
now its seems to me that the foreach version is 'up' 2 function calls
None of those are function calls.
They are all language constructs. Okay, each() *might* be a function...
I'm not sure how much difference there is in the number of language
constructs used, nor if they are even comparable in sheer numbers the way
functions are.
ah yes, lang constructs rather than function calls.
foreach is probably slower, I think, because it creates a *copy* of the
array to work on, so it won't mess up the original and its internal
pointer.
unless I'm mistaken its a copy-on-change, so unless you are changing the
the array inside the loop you don't suffer the actuall copy penalty - can
anyone
knowledgable on php internals confirm or deny this?
actually now I think of it you can use references in a foreach statement:
php -r '
$arr = array(1,2,3);
foreach($arr as $k = $v) {
$v++;
}
var_dump($arr);
'
which suggests that a copy is not (always?) being made...
Again, with 200 bytes, you are wasting your time to worry about any of this.
true, It's purely a theoretical interest - deeper understanding is alway nice
:-)
...its not even my 200 bytes we're talking about ;-)
on the while loop, all else being equal the foreach loop has to be faster
(given that calling functions is relatively very expensive)...
or is foreach() _really_ heavy when compared to while()?
Why don't you just benchmark it on your own machine and find out?
because I don't have the skills to write a test/benchmark that I _know_ is
kosher (and not skewed by a million of my misconceptions, besides I run so
much
stuff on my machine that speed can be severely affected by things like
apache or firebird running in the background
that and I lazy ;-) (or I just don't care enough to invest time investigating
this)
not that I care too much, I find foreach() more pleasing to the eye and
there is
less to type (in the given example).
I'm an old dog, and I don't quite understand for sure how this new-fangled
foreach thingie works. I'd spend more time looking it up and reading
about it than just typing what I *know* works. [shrug]

Re: [PHP] Sorting table columns dynamically on normalized MySQL tables [LONG]
Hello Jay,
Tuesday, April 19, 2005, 1:28:25 PM, you wrote:
J Normalization has no effect on sort order where any DB is concerned.
J Sort order is determined in the sort clause in the query. So if you want
J to sort by location and you are using MySQL your ORDER BY clause should
J be location(regardless of joins)
J SELECT foo
J FROM bar
J ORDER BY location
J returns
J course instructor location
J Science Bill Elementary School
J Basket Weaving Dave High School
J Math Dave Middle School
J Biology Jessica Middle School
Maybe I wasn't clear.
SELECT *
FROM Course
ORDER BY locationID ASC
Now the ORDER BY can be any one of five things based on the variable
passed by the hyperlink for the column they clicked on (location,
course, date, category, and instructor
Because locationID is an integer which directly relates to the
Instructors table id field (also an integer), there is no way in heck
that it can sort that any other way than numerically. There is no join
between the Course, Locations, and Instructors tables. All the Course
table knows is that there is an integer in the instructorID,
categoryID, and locationID field. Therefore it gets sorted
numerically, not alphabetically.
As I said, I was trying to keep the example simple. I actually have
the following tables in the DB.
Courses
Instructors
Locations
Categories
Students
Registrations
Supervisors
Courses contains information pertinent to a course.
- id
- name
- courseDate
- courseTime
- ampm (morning or afternoon)
- capacity (number of seats available)
- locationID (corresponding id from the Locations table)
- instructorID (corresponding id from the Instructors table)
- seatsLeft (counter for the number of available seats)
- description (what the course is about)
- categoryID (corresponding id from the Categories table)
Instructors
- id
- firstName
- lastName
- email
- phone
- image
- about
Locations
- id
- name
- seatingCapacity (How many true seats there are in the room)
- address
- directions
Categories
- id
- name
Students
- id
- firstName
- lastName
- email
- phone
- password
- username
- divisionOrFacility
- programArea
- supervisorID
Supervisors
- id
- firstName
- lastName
- email
- phone
Registrations
- id
- courseID
- studentID
- attended
So... For me to list the upcoming courses on the main page, I have the
following column in the table:
Course Name - From Course Table
Open Seats- From Course Table
Category - From Course Table (match id in Categories table)
Date - From Course Table
Time - From Course Table
Location - From Course Table (match id in Locations table)
Instructor- From Course Table (match id in Instructors table)
Category, Location, and Instructor are integers. What I did to get the
names respective to the integer value is that beforehand I built an
array for those three tables then I match the id from the Course Table
for each of the three with their respective array, and then display
the name.
Since the SELECT statement is based on the Course table, and the
Course table contains only integers, it's sorting by the integer value
of the categoryID, instructorID, or locationID in the Course table.
The actual SELECT statement is as follows:
$sqlCourses=SELECT * FROM . $tbl_courses . WHERE courseDate ' .
date(Y-m-d) . ' ORDER BY . $orderBy . ASC;
the $orderBy variable is set via $_GET['orderBy'] which is sent by the
table headers as below:
$tblHeaders = 'tha href=' . $_SERVER['PHP_SELF'] .
'?orderBy=nameCourse/a/ththOpen Seats/ththa href=' .
$_SERVER['PHP_SELF'] . '?orderBy=categoryIdCategory/a/ththa href=' .
$_SERVER['PHP_SELF'] . '?orderBy=courseDateDate/a/ththTime/ththa
href=' . $_SERVER['PHP_SELF'] . '?orderBy=roomIdLocation/a/ththa
href=' . $_SERVER['PHP_SELF'] . '?orderBy=instructorIdInstructor/a/th';
The sorting works just fine, but it's numerical ASC based off the
integer value (instructorID, categoryID, or locationID). It is *not*
alphabetical, which is what the customer wants.
If they sort by Location, the location column should be alphabetical
ASC, if by course name, then alphabetical ASC by the course name.
Is that a bit clearer now?
Sorry that this has degenerated into a MySQL question rather than PHP.
I was originally looking for how people handled it in PHP.
BTW, just for clarity sake on the arrays used to build the lookups to
display the list of courses, I'm doing an include with the following:
?php
//Get instructors --
$sqlInstructors=SELECT * FROM . $tbl_instructors;
$resultInstructors=mysql_query($sqlInstructors) or die('Failed to get
instructors. Please contact ' . $maintainer);
while ($rInstructors=mysql_fetch_assoc($resultInstructors))

Re: [PHP] Replacement Question.
Wow! Thanks.. That works great. Just one small hitch though. After it
prints all of the data properly, it adds one more '$date' on the end
which gets printed as '12/31/69 7:00:pm'. Is there a way to do all
groups - 1 ?

Are the group delimiters different from the field delimiters?
Ie, can you do:
$array_of_groups = explode('group_delim', $in_string);
foreach ($array_of_groups as $i) {
$array_of_fields = explode('field_delim', $i);
$date = date('m/j/y g:i:a', $array_of_fields[0]);
print $date {$a_o_f[1]}br /{$a_o_f[2]}br /br /\n;
}
YMMV of course.

[PHP] Classes, Constructors, References and Recursion
Hi,
I have this piece of code:
class test1 {
var
$data = 'hi',
$node = false;
function test1() {
$this-node = new test2($this);
}
}
class test2 {
var
$data = 'yoyo',
$root = false;
function test2($root) {
$this-root = $root;
}
}
$test = new test1();
echo('pre');
print_r($test);
echo('/pre');
And it outputs:
test1 Object
(
[data] = hi
[node] = test2 Object
(
[data] = yoyo
[root] = test1 Object
(
[data] = hi
[node] = *RECURSION*
)
)
)
while it should output:
test1 Object
(
[data] = hi
[node] = test2 Object
(
[data] = yoyo
[root] = *RECURSION*
)
)
I know there are some difficulties using references in constructors, but
I think this should be right..
I'm using PHP/4.3.11. Can anyone tell me what is wrong with this code or
why PHP behaves this way?

[PHP] 32 bit PNG (256 color alpha channel), TGA images, etc
I find it not quite right that imagecolorallocatealpha is limited to 128 levels right now (0-127) ... the png format can support 256 with true 32bit images. I am concerned about this because I am using php to make an application that loads a nonstandard image format (MM2/MC TEX) and converts it to png - but the format supports 256 alpha levels, imagecolorallocatealpha does not, and therefore I am losing small amounts of detail in the alpha channel by reducing it to conform to the max 128 levels idea. Can I get an explanation as to why it's limited at 128 levels instead of the preferred 256, and maybe an estimate or guess to whether or not this limitation will ever be lifted? On to the next part of this post. Is there any way to create an equivalent to imagecreatefrompng for tga (maybe imagecreatefromtga), /including/ alpha channel? I've found examples on php.net, but none of them take an image with more than 256 colors, much less one with an alpha channel. I'm not keen on the binary structure of the tga format, but i might be required to learn it this time..

Looks like mysqli is the new method of talking to mysql? Should I be moving away from the legacy mysql_* functions? I'm running php5 and mysql 4.1.11 on IIS5 and Apache 2. Why not use PDO :) Jared -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Robustly using XSLT across different versions of PHP?
Has anyone written anything, perhaps in PEAR or elsewhere, that allows for some portability of XSLT use across PHP 4 with Sablotron, PHP 4 with domxml, and PHP 5? I'm doing some work on a project at the moment, and the server it will be hosted on initially has PHP 4 compiled with Sablotron support. Unfortunately my workstation where I'm doing a lot of prototyping runs Fedora Core 3 and has PHP 4.3.11 compiled with '--with-xml' '--with-expat-dir=/usr' '--with-dom=shared,/usr' '--with-dom-xslt=/usr' '--with-dom-exslt=/usr'. All attempts so far to recompile Fedora's src rpm with sablotron have failed and frankly I've given up. Besides which, it's likely that at some we'll want to start using PHP 5. I can use the domxml XSLT support in PHP 4 on my FC3 box just fine, e.g. like this: ?php $filename = default.xsl; $xmldoc = domxml_open_file(control.xml); $xsldoc = domxml_xslt_stylesheet_file($filename); $result = $xsldoc-process($xmldoc); echo $xsldoc-result_dump_mem($result); ? but that isn't too much help given that that doesn't work on the production server. Has anyone done any work on creating something like PEAR:DB which will use the functions described here: http://uk.php.net/manual/en/ref.domxml.php http://uk.php.net/manual/en/ref.xslt.php http://uk.php.net/manual/en/ref.xsl.php depending on their availability?

Re: [PHP] 32 bit PNG (256 color alpha channel), TGA images, etc
Andrew D. Keyser wrote: I find it not quite right that imagecolorallocatealpha is limited to 128 levels right now (0-127) ... the png format can support 256 with true 32bit images. I am concerned about this because I am using php to make an application that loads a nonstandard image format (MM2/MC TEX) and converts it to png - but the format supports 256 alpha levels, imagecolorallocatealpha does not, and therefore I am losing small amounts of detail in the alpha channel by reducing it to conform to the max 128 levels idea. Can I get an explanation as to why it's limited at 128 levels instead of the preferred 256, and maybe an estimate or guess to whether or not this limitation will ever be lifted? On to the next part of this post. Is there any way to create an equivalent to imagecreatefrompng for tga (maybe imagecreatefromtga), /including/ alpha channel? I've found examples on php.net, but none of them take an image with more than 256 colors, much less one with an alpha channel. I'm not keen on the binary structure of the tga format, but i might be required to learn it this time.. Andrew It's likely limitation of gd or png library.

Re: [PHP] converting word document to plain text file
On Wednesday 20 April 2005 23:14, Cima wrote: them. is there a way to these types of files in php or some other way? The easiest way is to tell your users you expect file format to be text only. You can test for mime type by using built-in php functions (and should do so!). The hard way means that you need a parser for pdf, rtf, and doc files. PDF is open format so there will no doubt be some PEAR module for it. Rtf is quit ieasy to parse yourself, and doc is m$ propriety so that will be a lot more difficult to implement. Or better, you might find a commandline tool that can do the job for you, and call that from within php. Before doing so, please take at least one day to study security. Since you provide your users with a way to transfer files to your server. And you process those files then possibly users can hack your server. When you got it working, report back here and ask us to analyze your code for pointers on how to make it more secure. Good luck!

Re: [PHP] script
Thank you both, this was indeed helpful.
Now for one more question...
I'd like to get my code to calculate the time between the current date
(when the page is loaded by the visitor) and the very next Tuesday at
11pm. I suspect I can do this with date(w) but I can't quite figure
out how to make Tuesday the beginning or end of the week in order to
accomplish this...
maybe I'm going about this the wrong way.
Again, any pointers or assistance appreciated.

Hmm... well, using date(w) will tell you what day of the week it is, and you know that 0=sunday and 2=tuesday. use that and some logic to compute the number of days between today and the next tuesday. Then figure out how many seconds have elapsed for today and use that in conjunction with the number of days in between and the number of seconds to get to 11pm (23*60*60). Then substract the two... and pass that to date in the format you want.

[PHP] Regular Expression to replace pseudo-HTML?
Hi All, I'm hoping someone can help me figure out a regex that will replace pseudo-HTML codes in a string with desired HTML equivalents. In particular, I'm trying to implement a message quoting facility, such as when you click on the 'quote' button in phpBB. An example of a source string would be: source string [quote=John]Some quoted text. Some more quoted text. [quote=Mary]My older comment.[/quote][/quote] My current comments. /source string Ideally, I'd like this to become something like: regexed string div class='quotehead' John wrote: /div div cass='quote' Some quoted text. Some more quoted text. div class='quotehead' Mary wrote: /div div class='quote' My older comment. /div /div My current comments. /regexed string Given that pseudo-HTML seems common on bulletin board systems I'd hoped there'd be a published function available to handle it, but I haven't had any luck finding one and while I've been able to find a couple of regex examples (eg http://www.regexlib.com/REDetails.aspx?regexp_id=520) they appear to be aimed at ASP.NET rather than PHP and my attempts to get them working in PHP (hampered, admittedly, by my general confusion about regex's) haven't met with any luck. Truly, any help immensely appreciated! Much warmth, Murray
