Re: [PHP] Printing a PHP Class

Also, you could use print_r($obj);
to look at everything in the class, with arrays already expanded for you.

Re: [PHP] Reading URL in address bar

[Jerome Houston]

CGI.referrer?  are you a foxweb user? :-)

you can use  $_SERVER['REQUEST_URI'] for the page itself, plus (i think...) 
$_SERVER['SERVER_NAME'] if you need the hostname (of the server), too.

Re: [PHP] php server on Windows

[Jerome Houston]

Ditto on all that for me.  use apache.  the instructions on how to get them 
working together are good as long as you are diligent about reading *every* 
word.  no half-ass instruction following will do.  mysql is just as easy to 
set up, and you have to do *zero* configuration of php to get it working.

i've used this comination before, and at the time i had NEVER used php or 
mysql before, and it all worked together nonetheless.

The most stable version for server use is currently Win2k.

Re: [PHP] Image aliasing

[Jerome Houston]

morgan-
is there any way you can have those img tags (the ones with the height and 
width) changed to reference a php script?  you could write a script that 
reads in the image they're requesting, and takes a height and width as 
inputs, then uses php commands like imagecopyresampled() or 
imagecopyresized() to dynamically output a resized image?  maybe this would 
be too much load on your server, but it sure would cut down on the download 
time, and would almost *positively* give you better image quality.

might look something like this
http://yourserver.com/scriptpath/thumbnail.php?height=100&width=100"; >

with a script something to the effect of thumbnail.php: (assuming the file 
is a jpeg)

RE: [PHP] Seperating presentation from logic

[Jerome Houston]

Is there a particular reason everyone is skipping over the idea of using 
XML/XSLT?  What you're talking about is EXACTLY what XSLT was designed for.  
You can write scripts that access the DB, and output XML.  Then you just use 
XSL files written by your designers to translate your XML into HTML.  they 
get to choose EVERYTHING about what the page looks like.

Granted, your designers need to learn a little XSL, but it sounds like, for 
what you're doing, they wouldn't need to learn much.  If you're going to 
teach them to use something proprietary like pattemplate (as mentioned 
below), why not spend that time teaching them to use XSL, which is easy to 
use and isn't proprietary, it's actually W3 specified.

for info on how to get it working with php, go to:
http://www.webmasterbase.com/article/602

some people may disagree.

though i was just doing simple GETs to website, i happened to be doing a lot 
of them in nested loops (get one page, parse a bunch of URLs out of it, get 
a sub-page, find a link in it, get a file, etc...)

fopen()/fread() just started to crash after a couple of iterations.  i don't 
know if that's because i'm on win2k or what, but I enabled CURL and tried 
using it instead, and NO PROBLEMS whatsoever.  CURL turned out to be much, 
much more reliable for my use.

Re: [PHP] HTTPS vs. HTTP ?

[Jerome Houston]

If I could elaborate on colin's explanation
Mainly so that there is a fairly recent one of these in the archives
(not that anybody searches them :-)

Like miguel said encryption in an HTTP request/response pair is determined 
by your browser.

if the browser is making a request, and it sees an https:// at the beginning 
of the request URL, it will :
1.  get the domain's public key from a public key server
2.  encrypt the whole request with the domain's public key
3.  submit it to the web server.

If the web server sees that this is an encrypted request, it will :
1.  decrypt the request with it's private key
2.  process it and generate a response (usually in the form of html)
3.  encrypt the response with it's private key
4.  send it back to the browser

When the browser gets the response, it:
1.  decrypts it with the public key
2.  displays the html to the client user
3.  ***shows a lock icon at the bottom of the browser

Now, one of the things that many people are confused about is that they 
think there must be a lock icon at the bottom of the browser when they are 
entering sensitive info (like credit card numbers).  Nope.  The only 
important thing is that the form which takes the sensitive data SUBMITS to 
an https:// URL.  Because (as above) it will encrypt the request (which 
includes the sensitive data) BEFORE it submits it over the internet.  But 
most people don't know how to check that a form submits to an to an https:// 
URL.  So, the standard practice is to have the page containing the form 
which takes the sensitive data ALSO be an https:// URL, so that the lock 
icon is already there when the client user is entering that oh-so-prized 
sensitive data, even though there's nothing really to protect in that HTTP 
request/response pair.

PHP is, in a way, completely separate from the HTTP/HTTPS layer.  When PHP 
is started up by the web server, regardless of the encryption (or lack 
thereof) of the original request, PHP gets the non-encrypted (or already 
decrypted) request.  When it sends its response output to the webserver to 
be sent to the client, it sends that output unencrypted.  It's completely up 
to the web server to either encrypt the response, then send it out, or to 
just send it with no modification.

I hope that helps your understanding of what's going on with all this 
HTTP/HTTPS stuff.  I also hope that i've been clear about it.  It's kind of 
easy to get lost in terms.

Jerome

Re: [PHP] PHP and Object-Orientated Programming

[Jerome Houston]

oh, mucho disagree-o.

i dunno, maybe the people who say that it will slow you down have HUGE 
projects, and HUGE classes with hundreds of member variables, but i use OO 
for all the DB interactions (i have a class with get, update, insert, delete 
methods, etc. for each table) and i think it works just fine.  i even wrote 
a script to generate those classes, so if the DB structure changes, i only 
have very minimal code editing.

maybe if you're holding hundreds of big classes in memory at a time, this 
could give you a problem, but even if a user is looking at a data set that 
has thousands of results, you're not going to be showing them all on a page 
at once, so you don't need them in memory  just be smart about your 
queries.

even with all the data being in objects, and lots of those objects in 
memory, i don't see a big difference.

[PHP] MSSQL 2000's 'real' type kills php

[Jerome Houston]

Hi,

i'm working on a win2k server running php 4.1.1  accessing MSSQL server 2000 
on a win2k server.

i've got a problem with a table that has 'real' numbers in it.


codeinventory name
PRC01   2.33  Prince Brand Chips
FCA13   9.934E-2  Frozen Calamari


when i
mssql_query("select * from products");
or, more specifically
mssql_query("select inventory from products where code = 'FCA13'");

BOOM!  php crashes, and i get a pop-up window in MSIE that says, "IE cannot 
open the site ..  the connection with the server was reset"

but

mssql_query("select * from products where code = 'PRC01'");
works like a charm.

granted 9.934E-2 isn't an actual number for inventory, it should be 0.10 
.  BUT, i can't help that.  my application is not the only one that uses 
this data.

this happens with various numbers that have high precision.

anyone run into this before?  any suggestions?

thanks VERY much in advance,

jerome

[PHP] RE: MSSQL 2000's 'real' type kills php

[Jerome Houston]

Thank you for your reply.

i can't tell if your solution works yet because
PHP can't seem to handle multiple SQL statments in one call to 
mssql_query().
when i do what you said:

mssql_query("SET TEXTSIZE 2048 select inventory from products where code = 
'FCA13'");

I get:

Warning: Supplied argument is not a valid MS SQL-result resource in 
utils.php on line 50

AND, from then on, no mssql_*() functions work

Warning: MS SQL: Unable to select database: PRODDB in utils.php on line 48

Warning: MS SQL: Query failed in utils.php on line 50

Warning: Supplied argument is not a valid MS SQL-result resource in 
testms.php on line 72


i thought maybe it was a different incarnation of the same problem, but now 
i REALLY don't think so.  It turns out when i do any query with mutliple 
statements in it (even if i don't use the result set for something), it 
causes the same thing.  all mssql_*() functions are rendered disfunctional.  
even something that doesn't access data in teh DB, like:

mssql_query("declare @P1 float \n set @P1 = 10.00 \n select @P1");

i get the "not a valid MS SQL-result resource" error.

Sorry to just give out more problems, but anyone know anything about this.  
is there a setting i can change to make multiple statements OK for PHP?  I 
know the statements run just fine on the SQL server, because i ran MSSQL 
Profiler on the server to catch all statments and errors, and no errors 
happened.

thanks once again, everyone.

Re: [PHP] help with undefined variables, please

[Jerome Houston]

hi-

it is not REQUIRED for variables to be initialized in PHP, but if your error 
reporting is on too high, it will tell you, just to make sure you know.  to 
turn your error reporting to a different level, you can change your php.ini:

http://www.php.net/manual/en/configuration.php#ini.error-reporting

or just change it for this script

http://www.php.net/manual/en/function.error-reporting.php

hope this helps,

An array in PHP is actually an ordered map. A map is a type that maps values 
to keys.


we're not working with C where each array value is right next to each other 
in memory.  it's an abstraction that does the job intelligently, but gives 
you a familiar-looking interface.

Thanks.  So the next() and prev() functions just traverse an array using
some type of linked list?  This is what precludes direct access to
specific elements?

yah, there's a function. (isn't there almost always?)

http://www.php.net/manual/en/function.array-values.php

it gives you a numerically indexed array of all the values in your current 
array, associative or not.

There is no [0]...only ['one'] and ['two']...

Look through the array functions, there may be a way to reassign the keys...

RE: [PHP] uh, oh errors?

[Jerome Houston]

one REALLY notable advantage is:

if you us ob_*() functions, instead of writing HTML pages with php tags 
inserted, you can write XML pages with PHP tags inserted.  then after you're 
done, you can pass the contents of the output buffer to an XSLT processer 
like sablotron, THEN outputting an HTML page.

What are some benefits to using output buffering versus just letting it
generate as it goes?

Subject: Fw: [PHP] uh, oh errors?


Don't feel bad about this.  This is something that messes a lot of
people
up.  The browser knows where your headers end and where content begins
by
adding blank line between the headers and the rest of the page.  ALL
headers
must come before any content is printed to the page.  PHP will give you
that
error if you attempt to write a new header.  So in fact your problem is
not
on Line 13.. but is actually on Line 11.  There are at least two ways to
avoid this...

1. Don't print content before headers.  :)
2. Use output buffering to write the whole page before it is outputed
to the
browser.

Hope this helps,

Re: [PHP] PHP in HTML

[Jerome Houston]

yeah, just find in your web server where to tell it what kind of files to 
send through php.

there are also possible good reasons for sending .html files through php.  
like if you don't want users to know that your website is written in php.

Your Apache config file will be set to only parse PHP pages if they have the
.php extension this is a feature, not a big, because otherwise every
html page on your server will be parsed, rather than just the php ones...
you could modify your apache config iff you wished, but I wouldn't.  .html
for HTML, .php for PHP, all is well.

Re: [PHP] Comon guys, please help.

[Jerome Houston]

This isn't a php question, which is why you aren't getting any answers...
there are many ways to go about this.  with cybercash and payflow, and all 
other payment gateways, you DO need a merchant account.  specifically, a 
merchant account that is compatible with the payment gateway you're trying 
to use.  Some services will accept credit cards for you, but charge you a 
more hefty percentage of sales (or some other fee system, like a 
per-transaction fee) to make it worth their while to write the software that 
does the credit card processing real-time for your website (like 
www.ezcharge.net).  most important is that you find somebody who gives a 
good deal on what THEY charge YOU, and who you can connect to in a way that 
you have available to you.  Lots of payment gateways just need you to have a 
utility that can send a HTTPS (!note the S !) POST or GET - which PHP by 
itself can't do yet - wait for 4.3 (and even then you'll need OpenSSL 
support compiled in).

maybe that will help, maybe it will further confuse you.  i leave it to the 
gods to decide.

  Hi Guys,
  Special greetings to all of you who have helped me in the past.

  As some of you know i just bought a PHP book called "Php Blackbook" which 
i
  heard is really good.
  Anyway, In chapter 4 it talks about credit cardsand then CyberCash
which
  is owned by verisign and payflow which too is owned by verisign. The book
  also gave me some url and RFCs to look up.
  I dont know if its coz i'm a newbie to PHP or just dumb but I just cant
  understand this...its too damn high funda for me,
  I know google is my pal so I went there, read up on differient RFCs and 
got
  even more confused!

  I just want to know have any of you worked on these systems? eg CyberCash
  and PayFlow?
  Does this mean that if i want to start accepting credit cards on my site i
  wont have to pay for a credit card merchant account?

  PLEASE HELP if you know the answer or can offer any suggestions,comments
  ANYTHING.

  Have a great day,
  -Ryan.

[PHP] ADODB - whaddya think?

[Jerome Houston]

Testimonial time!

Despite ROCK STAR assistance from a PHP developer, I'm having troubles with 
mssql_*() functions.  most of the problems are gone (or being fixed by some 
AWESOME people), but to make use of those fixes, i've got to use php v 
4.3-dev.  and there's other bugs in that (as there should be).  so i've been 
looking for alternatives to using the mssql functions...  and i've found 
something that looks promising: ADODB.  for those of you who don't know, 
some people have just written some code that attempts (and looks as if it 
does a pretty good job) of unifying ODBC calls for lots of different 
databases.  their website: http://php.weblogs.com/ADODB

What i want to know is:  does anyone have experience with these libraries?  
I tested them briefly, and it seemed to work like a charm, but so did the 
mssql_*() functions, until i got into some of the nitty-gritty uses of the 
DB.  Will lots of little bugs come about, the more i use it?  or have they 
ironed most of that out?

thanks for your opinons, and i apologize for possibly spurring another 
loquacious debate amongst smart people :-)

Re: [PHP] Post form values - script flow

[Jerome Houston]

Looks good Tim.

if you're going to do it this way, make sure register_globals is set on in 
your php.ini.  also you check isset($srch) AND strlen(trim($srch)).  in most 
cases, both checks won't be necessary.  unless you have high error 
reporting, and php will complain if you check a variable that hasn't been 
set yet.

I am very new to PHP about two hours.  I have a search page that I post back
to the same URL.  When the form is loaded I check to see if the seach
variable is set ($srch is the name of the text box on the form) and then
determine what function to call.  I either call a welcome message function
to be printed to the page or a function to search a database and build a
table of results.  I have included my script belowMy question is:  Is
this a good way to handle search forms with PHP?  Since I have no examples
to work from I am not sure what the proper way is.

Thanks for the help.

  if (isset($srch)){
if (strlen(trim($srch)) > 0) {
$srch = strtoupper(trim($srch));
buildtable($srch);

dispwelcome();

RE: [PHP] image_create(), header.....

[Jerome Houston]

While Natalie's solution is a valid one, i have another

first - the error you're getting is because the headers are sent AS SOON as 
you echo, print or output html outside of your  tags. you're echoing 
something before you call ob_start();

second- the reason this doesn't work, is because you're trying to write 
binary image bytes into an text html page  I think what you want is 
something like this (actually 2 scripts):

script1.php :
';
echo '';
?>

script2.php :

You can save them and then call them up, but then you have to use a cron or
something to empty out the folder.  Here's how I save it:

//Image created and everything up here, this is the very end of it
$myTime = time();
ImagePNG($im, "../spool/jp$myTime.png"); //this creates a unique name
chmod("../spool/jp$myTime.png", 0666); //leading 0, then the code for the
mode you want
ImageDestroy($im);

print "";

Hello,

I have about 10 function definitions that I want included on every page in
my website. Instead of calling:



on every page, I'd prefer to have the functions automatically loaded into
memory when a user visits any page of my site. I was thinking that there may
be some what to do this with a root-level .htaccess file, but I'm not sure.

Can anyone offer a solution?

Thanks,
