[PHP] Re: Catalog or cart
Hi Ryan, I've used osCommerce as a catalog before, but it's a bit of a pain to customize. ZenCart is supposed to be easier, but I haven't tried it yet. For the last project I did of this kind, I wrote my own catalog script and I feel a lot more comfortable with that. I do realize that it'll require a bit more work to add a cart to a catalog like that in the future, though, unless you use something simple like the cart provided by PayPal, but it's PayPal only.

The reason i was leaning towards a cart is, if he ever decides to sell online, i dont want to build a whole extra piece of software to go with the catalog.

[PHP] get_defined_vars in all scopes?
Hi! I'm using this at the end of a script echo 'pre'; var_dump(get_defined_vars()); echo '/pre'; but it only returns what get_defined_vars gives, which is what's available in the current scope. Is there any way to get also the vars used in functions that weren't globalized? TIA!

Many functions may end at different places, they not alway reach the end, so I guess I could do it globalizing every var/arr, at least the ones I'm most interested in. Is there some program I can use that'll monitor the vars when executing the script? I think Xdebug [http://xdebug.org/] does that with functions, but am not sure if it'll work with vars.

i'd like to be able to strip only one type of HTML tag from a web

That's why I was hoping someone knew of a better way to accomplish
this. Any suggestions are welcome.
Thanks in advance,

I'd probably do this:
$str = preg_replace('~a.+?/a~is', '', $str);
If you wanted to keep the anchored text and URLs, then something like:
$str = preg_replace('~a href=(.+?).*?(.+?)/a~is', '$2 [$1]', $str);

Terence wrote:
Hi,
Say you have a querystring - index.php?myname=joe
To determine whether myname has a value I have come to the following
conclusions / shortcomings when using one of the following:
ISSET = as long as the variable myname exists it's set, but there's no
guarantee of a value
!EMPTY = if your name = 0 (zero) then it's considered empty, for all
else it seems to work
STRLEN = I have found this to be the only sure way to know.
Is there any other way, or should we always use a combination of ISSET
and STRLEN?
Wouldn't this work?
if(isset($_GET['var']) !empty($_GET['var'])){

[PHP] Benchmarking a script
Hello,
I have a script I am optimizing and want to compare the before and after
in speed. So I wrote a few lines to loop this script but I have a
problem. In the script I'm optimizing there's some function definitions
and when the script starts the second iteration it throws an error
because the function already exists. How can I modify my benchmark code
to make it work? This is what I have:
?php
$bench_n = 1000;
for($bench_i=$bench_n; --$bench_i=0; ){
ob_start();
$bench_time1 = array_sum(explode(' ', microtime()));
// script start
// script...
// script end **
$bench_time0 += array_sum(explode(' ', microtime())) - $bench_time1;
while(@ob_end_clean());
}
echo 'preTot Time: ' , $bench_time0 , 'br /Loops:' , $bench_n ,
'br /Avg Time: ' , ($bench_time0 / $bench_n) , '/pre';
?
Thank you very much in advance.

Jason Barnett wrote:
Well you could put all of your function definitions into a separate
file. Then, just include the function file before you loop through the
code that uses the functions. Or as an alternative you could also do:
?php
if (!function_exists('name_of_function')) {
function name_of_function() {
// do something
}
}
?
But this really isn't a good idea. Try to put the function definitions
into a separate file if that's feasible.
Jason
Thank you Jason. The problem I'm having is that part of what I'm
benchmarking is having to define the functions compared to having not
to. Basically part of the speed improvement is taking big parts of the
code out of functions, so I need the definitions there :/

Often I end up using a dumb IF statement which to me seems that
it could have been done some other way.
Example :

) {
// Here we do nothing
} else {
// This is where we do it

Wouldn't it then be like this?
if($_GET['id']!=1 $_GET['mode']!='home' (isset($_GET['item'])
$_GET['mode']!='news'))
// Do stuff.
I may be wrong though. Note that I used AND instead of OR for the
conditions, because you want them all true at the same time. But then
again, you'd have to test it, with so many conditions it becomes a bit
difficult to picture it in my head :P

You're right, that fixed the space capturing.

BTW, if you use var_dump or var_export, you can see the whitespace :-).
$arr = preg_split('/(^\s+)/',word1 word2 word3., -1,
PREG_SPLIT_DELIM_CAPTURE);
The ^ means beginning of string.
This will still give you an empty string in $arr[0], so do something
like:
unset($arr[0]);
$arr = array_values($arr);
Or just write your code to expect the extra entry. ;-)
The ^ did the trick, thanks! I noticed the empty [0].
I'm doing this to display code in an indented way and to keep the indent
if the line wraps, instead of going back all the way to the left. So I'm
putting the spaces in a td and the code line in another td, with a
table for each line. I tested it and looks very well, now I'm writting
the code to generate it.
Thank you all for your help! :)

[PHP] Re: Separating spaces from the rest
Thanks! I was just reading that function in the manual when I got your
reply. I tested it but I still have a couple of problems with it.
print_r(preg_split('(\s+)',word1 word2 word3., -1,
PREG_SPLIT_DELIM_CAPTURE));
I get this:
Array
(
[0] =
[1] = word1
[2] = word2
[3] = word3.
)
In [0] the spaces aren't there and it's splitting the other spaces too,
where I need to only split the leading spaces. How should I write it?
TIA,

[PHP] Re: $PATH_INFO not working
Noel Da Costa wrote: Hi, Anyone know what might stop the $PATH_INFO variable from working? I developed a nav system using this which works on the test server, but not on the live server. I'm guessing this is something to do with the way PHP (4.2.2) and Apache (2.0) were compiled on the live server (I've posted that question on php.install), but what I'm wondering is... Is there perhaps a code fix/work-around I could apply in my scripts to replace the $PATH_INFO with something that achieves the same effect, without having to redisign my entire nav system. Thanks, Noel I think you have to enable accept path info in Apache 2, it's on in 1 by default. I'm not sure exactly what the command is, but you can search based on that.

[PHP] Conditional Functions
Hello, I was wondering if using conditional functions would save resources. The thing is that there's many functions in the code I'm using, but most aren't used in each case. I was thinking that maybe, even if the functions are in the included files, I could not define them making them conditional. Would this benefit the script? How? TIA.

Re: [PHP] Conditional Functions
[snip]
Maybe you could group them by purpose and put them into different include
files. Then you just include the file containing the functions you need at
this point in the script.
Regards,
Torsten Roehr
[/snip]
The functions are already grouped in different files, but even then, not
all the functions included are used every time. The thing is, that
there's too many different values for $action and each has it's own set
of functions used. So creating an include file tailor-made for each one
is a bit difficult, specially since many functions are used in more than
one action.
So I thought that maybe I could only define the needed ones in each
case, although there's more in the include file. Example:
if ($in_array('Hello', $functionArray))
{
function Hello()
{
echo 'Hello';
}
}
I understand that the whole php file will be parsed, or does the parser
skip the whole block inside the if when the condition is not met? But
even if it is parsed, if the condition is not met, I believe that the
function won't be defined, so I assume this would at least save RAM or
something, right? Or not at all?
TIA,
Anguz

[PHP] Weird replacing
Hi,
I wrote a code to change the urls in my forum, to a new format. I
did it with output buffering and inside it, I used
preg_replace_callback, which worked great for me. But I shared
this code with the forum program community and there's a person
that can't make it work. He says his Apache gets caught up in a
loop or something. So I looked for an alternative to
preg_replace_callback. The way I did it is with preg_match_all
and then changed each element in the array and saved the changed
elements in a new array, then I just str_replace using the arrays
as find/replace. This solutions worked fine, almost. I use two
functions to do changes to the urls, one to make them relative
and the other to change symbols in the query, to something more
friendly to search-engine spiders. The function to make them
relative works great with the new method, as it did with
preg_replace_callback, but the other function, the one to replace
symbols in the query, is acting in an odd way.
Here's function
?php
function spider_url($match){
if(!strstr($match['2'], 'action') || strstr($match['2'],
'display') || strstr($match['2'], 'messageindex'))
return $match['1'] . '/' . str_replace(array(=, ;,
), array(-, _, _), $match['2']);
return $match['0'];
}
?
if I call it with this
?php
/// $scripturl is the var that has the url to the forum
script, like http://example.com/bbs/index.php
$buffer = preg_replace_callback('/(' . preg_quote($scripturl,
'/') . ')\?([\w;=~+%]+)/i', 'spider_url', $buffer);
?
it works great and the url
http://example.com/bbs/index.php?board=1;action=display;thread=12
3;start=1
changes to
http://example.com/bbs/index.php/board-1_action-display_thread-12
3_start-1
but if I do it with this
?php
preg_match_all('/(' . preg_quote($scripturl, '/') .
')\?([\w;=~+%]+)/i', $buffer, $match_spider, PREG_SET_ORDER);
for($i = 0; $i count($match_spider); $i++){
$arr1_spider[$i] = $match_spider[$i]['0'];
$arr2_spider[$i] = spider_url($match_spider[$i]);
}
$buffer = str_replace($arr1_spider, $arr2_spider, $buffer);
?
then the url comes out like this
http://example.com/bbs/index.php/board-1;action=display;thread=12
3;start=1
It changes just the first part, up to the semicolon... I did
other tests and there was one where changed everything up to the
semicolon right before 'star'
I can't understand what's going on, so if someone has a clue,
please tell me. Thank you very much in advance for taking your
time reading this.
