Hi.
I've been doing some reading trying to figure out why I would want to
use cURL. I have not found a solid reason yet. Does anyone have a
useful example on why you would want to use cURL?
Thanks,

It allows significant configurability and flexibility over PHP's more
direct functions, for example, the ability to set a timeout, or get more
direct control over output. You only have to read the curl documentation
to see that it can do a lot of things that other PHP functions just
can't do.
I would suggest that you probably shouldn't try to find a reason to use
curl, rather a reason to use curl will find you.

Interfacing with payment/shipping gateway APIs. For example, in my
store I must send post data to a payment gateway to tell them the
amount, cc#, etc. and they will return text telling me the transaction
passed/failed/etc.

well, there are more reasons you should use cURL ..
- control and flexibility of the output,
- post variables,
- can interact with secure servers (ssl - supports certificates)
- can use with proxys (http/socks)
- set timeouts
- easily modify headers :)
- use different ip`s of the server when it`s used (if it is configured to do so)
please read documentation at php.net/curl before changing your mind to
not use it. it helps you a lot in your applications. an old frend told
me.. you`ll love this class - what to see.. it happend :)

Oh this was good.
I added a while loop to insert extra strings 0 in front of the number to add
if the string is less than 5 chars short.
I forgot to mentinon that the string actually could be shorter (just found
out) and the code didn't work with fewer than 5 char strings.
But now is rocks.
Thanks again.

You can also do this with a regular expression:
$iNumber = '123456789';
$sPattern = '/(\d+)(\d{2})(\d{2})$/';
preg_match($sPattern, $iNumber, $aMatches);
Then $aMatches contains:
Array
(
[0] = 123456789
[1] = 12345
[2] = 67
[3] = 89
)
The regexp pattern /(\d+)(\d{2})(\d{2})$/ means:
(one or more digits) (two digits) (two digits) [end of string]

[PHP] file_get_contents
I am trying to read the contents of a PHP page for an audio player
and put it into a textarea to be copied and pasted into an HTML
page.
The trouble is the textarea shows unparsed PHP code and I just want the HTML.
The code is:
$player = file_get_contents('player.php');
//Strip out unnecessary HTML Code
if(preg_match('/!-- Start Player Code --(.*)!-- End Player Code
--/s', $player, $matches)) {
$code = $matches[1];
}
echo textarea name=\textarea\ cols=\70\ rows=\15\ . $code .
/textarea;
echo BR;
echo a href=\player.php\Click Here/a to view the player \n;
Looked at using eval() but found this:

[PHP] ob_start() and a callback function within a class, not updating ob_get_level().
Hello there,
I have a question about ob_start() and ob_get_level().
When i use ob_start(), and then check ob_get_level(), it shows me 1.
This is a normal behavior.
Now when i do the following ob_start(array('ClassName', 'ClassMethod')).
It does execute the methode, but it doesn't update ob_get_level().
Is this a normal behavior?
Thx in advance.

[PHP] printing page functionality
Hi, We are in need of a printing functionality for our webpage. The problem is that some of our pages has a greater width than a A4 paper so not all of the content will be printed when using the built in printer functionality in the browser. Is there any useful script out there that can take the necessary content of the page and convert it to simple text and columns that will fit the paper when printing? or even better, a server application that can take the full content of the page and convert it to pdf or an image in a rescaled version that will fit the A4 paper? I've had a look at these HTML to PDF conversion apps: http://www.digitaljunkies.ca/dompdf/ http://www.rustyparts.com/pdf.php But they don't really cut it as we are using relative and absolute positioned divs and they don't have support for this.

Re: [PHP] CSS / PHP / Javascript
You can use a browser sniffer, where they've done all the work for you, and then link in the appropriate stylesheet using document.write(). I don't have personal experience with the IE conditionals, but I would be concerned that they'd get you into a bit of a box when it comes to recognizing other browsers. See: http://www.webreference.com/tools/browser/javascript.html Jochem Maas wrote: hmmm, this reply turned into something that resembles a rant about halfway thru... still ... maybe it's helpful in some way. Ed Lazor wrote: I'm reading a book on CSS and how you can define different style sheets for different visitors. I'm wondering how you guys do it. The book recommends using Javascript functions for identifying the user's browser and matching them with the corresponding style sheets. Anyone using PHP for this instead - specifically with defining style sheets for different target browsers and platforms? having to define CSS files for particular browsers and/or platforms is indicative of the crap we have to deal with - in theory you should NOT be targeting browser/platform specificallt AT ALL. you should be writing stylesheets for different types of user-agents (as defined by the W3C media types) - but who is really doing that. I recommend trying to build your sites using CSS that all browsers understand - i.e. avoid software/platform/version specific hacks whenever possible - when you have to add such a hack try to use a technique that you can unobtrusively incorporate into an existing CSS file. the man named tantek has lots of techniques you can abuses ;-) : e.g. http://tantek.com/CSS/Examples/midpass.html also consider that maybe you shouldn't try and tackle every visual discrepency between 2 different browsers/platforms! - you may have clients who bully you into 'fixing' layout in WeirdBrowser1.4 for instance - you need to develop a means to explain the problem to clients in such a way that they understand that not everything is under your control, and that they can't make you endlessly chase moving targets (i.e. make the client understand that web != print). if a client is willing to pay for every mindnumbing hour spent fixing arcane browser specific display 'bugs' then everything is okay - but don't get stuck working for weeks for no pay because some marketing manager has 'decided' he/she knows better what a website is and to what extent you must comply to his implicit wishes [i.e. you can break every 'rule' of website building and ignore/rape any/every relevant specification/standard so long as everything ispixel perfect in every browser according to the original mockup supplied by a graphic designer who can't even grasp the concept of screen resolution (I know plenty of print-based designers that fall into this category)] -Ed --PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- _ Myron Turner http://www.room535.org http://www.bstatzero.org http://www.mturner.org/XML_PullParser/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Use curl or fopen() to make a request to that PHP page, instead of reading
in the actual contents of the file.
Example:
?php
$url = 'http://blabla.com/player.php';
$ch=curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);
curl_setopt($ch, CURLOPT_TIMEOUT, 120);
curl_setopt($ch, CURLOPT_USERAGENT, Mozilla/4.0 (compatible; MSIE 6.0;
Windows NT 5.0));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$buffer = curl_exec($ch);
curl_close($ch);
echo TEXTAREA ... . $buffer . /TEXTAREA;

if I request the following I get a page with a player into:
http://www.tnhosting.co.uk/scripts/gclub/player.php
if you do the following you will get the same html source as my browser
does - if it doesn't then you are doing something wrong - quite simply
php is transparently making a http request to the webserver there is no
way the webserver will differentiate between your script and every other request
and give your the scrip the source code while everyone else is recieving
the result of running the script:
file_get_contents(http://www.tnhosting.co.uk/scripts/gclub/player.php;);
below is the oneliner I used to prove this:
php -r 'echo
file_get_contents(http://www.tnhosting.co.uk/scripts/gclub/player.php;);'

RE: [PHP] file_get_contents
Yes, I realize that now ;)
I didn't read it thoroughly enough before I posted :P
I think what Tom is referring to as PHP code is just the extra HTML tags
around the object tag that he is trying to strip out.
Tom -
Try this:
?php
$code =
file_get_contents(http://www.tnhosting.co.uk/scripts/gclub/player.php;);
$nstart = strpos($code, '!-- Start Player Code --');
$nstop = strpos($code, '!-- End Player Code --');
echo TEXTAREA . substr($code, $nstart, $nstop-$nstart) . /TEXTAREA;

Re: [PHP] file_get_contents
Confused!
I'm now getting:
file_get_contents(http://www.tnhosting.co.uk/scripts/gclub/player.php)
[function.file-get-contents]: failed to open stream: Connection
refused in
/home/sites/tnhosting.co.uk/public_html/scripts/gclub/updateplaylist.php
on line 75
How come you can access it and I can't?!?
Permissions are 755.
Obviously I was getting it when using file_get_contents('player.php')
but when using the URL I get connection refused.
(Don't think that it makes any difference, but allow_url_fopen is on)
BTW, Brad, I was stripping the HTML tags around the object ok, but I'm
echoing variables in player.php.
$song_url $song_title, are read from a seperate file after upload
and that is what's being updated by this script, but the textarea was
showing the php code.
Thanks for your patience, guys.

Sessions work generally, and I can log in to my application and do certain things that require a working session etc. It's only when I used a page that posts a large amount of data that the problem is apparent. I've tried it with overridden session handling functions that store session in a db too with the same results. In my test here, you can do a GET request several times and get the same id, it's only when you do the POST request that the bug is presented (at least for me). Cheers for the suggestion tho'.

You could also name the file *.csv and use a comma as a delimiter instead.
Don't forget to put quotes around any data that may have tab characters in
it. (Or commas if you're using csv)

thinking gets me to create a loop for 5 through 1, repeated twice, and
the second time I add '5' to the index value. There's got to be a
saner way...
Something like this perhaps...
$arr = array(...);
$per_row = 5;
$elem = count($arr);
for($i=0; $i$elem; $i++) {
if( $i == 0 )
echo tr;
if( $i % $per_row == 0 )

Re: [PHP] Looping through array
If you know the array elements, you may not need to loop. Why not just echo the particular array elements i.e. td?php echo $array[2]; ?/td for example?

$first_row = '';

In order to figure out the best PHP logic to generate the series, I'd first make sure the markup is solid. I realize that you've already indicated a table markup in two rows, but I'd like to examine that. Can you tell us why the numbers are in this particular sequence? Do the numbers represent items that are conceptually in ascending order but are presented in reverse order on the screen? If so, I'd wonder whether someone reading the page with assistive technology might be confused by the reverse order, and I'd try to find a way to mark them up ascending and then change the sequence stylistically. Are they split into two rows because they represent two discrete groups in the data set or because of display considerations? If the latter, I'd argue that they don't really belong in two table rows; that using tables to force presentation is misapplying the tool. Have you considered an unordered list, floated right, wrapped in a container whose width naturally forces a wrap after the fifth item? I like that solution because it allows you to mark up the numbers in sequence and in future change the number of items in the sequence and/or change the way the series is presented visually without having to mess with the logic generating the markup.

This appears to work for me:
preg_match('/\[([A-Za-z0-9\s\'.-:underscore:]+)\|([A-Za-z0-9\s\'.-:underscore:]+)\]/i','[Test
1|Test 2]',$matches);
print_r($matches);
produces:
Array
(
[0] = [Test 1|Test 2]
[1] = Test1
[2] = Test2
)
Alternately, I would use the following regex: /\[([^\|]+)\|([^\|]+)\]/
which is a little cryptic, but very flexible for what you mention above.
It works for me as well...

Dotan,
I'm surmising what you really want to do is grab all the characters
between [ and | for the first field, and everything from | to ] as
the second field. I would therefore identify the first field with:
[^\]|]
anything except the close-bracket and the vertical pipe
and the second field with:
[^\]]
anything except the close-bracket
Therefore:
/\[([^\]|]+)\|([^\]]+)\]/

Thanks, Paul. I've been refining my methods, and I think it's better
(for me) to just match everything between [ and ], including spaces,
underscores, apostrophies, and pipes. I'll explode on the pipe inside
the function.
So I thought that a simple /\[([.]+)\]/i should do it. This is the line:
$text=preg_replace_callback('/\[([.]+)\]/i' , findLinks, $text);
This is what it is doing:
1) on [~~] where ~~ does not include spaces nor pipes: The function
replaces [~~] with .
2) on [~~] where ~~ includes a pipe, but no space: The function does
not replace anything.
3) on [~~] where ~~ includes a space, but no pipe: The function does
not do what I intend it to do, and I am unable to figure out exactly
what it is doing.
3) on [~~] where ~~ includes a space and a pipe: The function does
not replace anything.
However, this function:
$text=preg_replace_callback('/\[([A-Za-z0-9\|\'.-:underscore:]+)\]/i'
, findLinks, $text);
Does what I want it to when there is no space, regardless of whether
or not there is a pipe. It does not replace anything if there is a
space.

Hey Børge,
If you need to left-pad with zeroes, PHP comes to the rescue:
http://php.net/str_pad
However, if you're using the regular expression
method then you might not need to pad the
number. You can change the pattern from this:
/(\d+)(\d{2})(\d{2})$/'
to this:
/(\d*)(\d{2})(\d{2})$/'
so it won't require any digits before the final two pairs.
* 0 or more quantifier
+ 1 or more quantifier
http://ca.php.net/manual/en/reference.pcre.pattern.syntax.php
Paul
Cool solution, and it works. =D
I do however need some chars to fill in on the finished product for the look
of it all, so the 0 is needed... Witch is a bit of a shame with this cool
string.

Well, just to make sure you don't discard regexp unnecessarily...
// the pattern guarantees five digits, then two, then two:
$sPattern = '/(\d{5})(\d{2})(\d{2})$/';
// prepend 9 zeroes to the number to enforce the minimum requirements:
preg_match($sPattern, '0' . $iNumber, $aMatches);
Results:
$iNumber = '';
$aMatches:
(
[0] = 0
[1] = 0
[2] = 00
[3] = 00
)
$iNumber = '123';
$aMatches:
(

[PHP] Dynamic Year Drop Down
I want to build a select drop down that includes last year, the current year and 3 years into the future. Obviously, I could easily hard code this or use a combination of the date and mktime functions to populate the select. However, I'm looking for a more elegant way of doing this. Thanks for pointing me in the right direction. Al Padley -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Dynamic Year Drop Down
Quite simple:
$this_year = date('Y');
for ($i= $this_year-1; $i $this_year+3; ++$i) {
print option value='$i' .
($i==$this_year ? selected='selected' : '') . $i/option\n;
}
Obviously modify for however you're doing output. (Note that you DO want to
have the redundant value attribute in there, otherwise some Javascript things
don't work right in IE. Good habit to get into.) I don't think it can
really get more simple and elegant.

This works for me, simple and easy.
// Grabs current Year
$year=date(Y);
// Number of years you want total
$yearEnd=$year+10;
// Generate Drop Down
for($year=$year; $year = $yearEnd; $year++) {
print option value=\$year\$year/option;
}
Thanks. This was close, but it didn't account for the first option
being last year. I edited and ended up with this which works.
// Grabs current Year
$year=date(Y);
$yearFirst = $year-1;
// Number of years you want total
$yearEnd=$year+2;
// Generate Drop Down
echo select\n;
for($year=$yearFirst; $year = $yearEnd; $year++) {
print option value=\$year\$year/option;
}
echo /select\n;

Re: [PHP] Dynamic Year Drop Down
Thanks, Larry. This was close, but didn't quite work. I played around
with the syntax and the following worked great.
$this_year = date('Y');
echo select\n;
for ($i= $this_year-1; $i $this_year+3; ++$i) {
echo option value='$i';
if($i == $this_year)
echo selected = 'selected';
echo . $i . /option\n;
}
echo /select\n;

[PHP] odd behavior of stripos() with === operator
HEllo all,
After pulling my hair out for several hours trying to figure out why my code
wasn't working I built this little test and ran it, the results are interesting
in the least, and to me, surprising. It is possible that I have done something
wrong, but I checked and rechecked this in the documentation.
It appears there is either a problem with the === operator (or my brain...)
If you don't mind, I'd like to see what you all think.
I am running php 5.2.0 on a linux redhat 9 box with Apache 2.2 (the php 5.2.0
install is brand new, perhaps I set it up wrong?)
anyway here is the code I wrote, and the output from it...
$found = stripos(abcdefg, abcdefg);
echo found = stripos(\abcdefg\, \abcdefg\);\n
echo The value of found is = : $found\n
// 1a) --- needle was found in haystack THIS SHOULD BE
if ( $found !== FALSE ) {
echo found does not equal FALSE\n
}
// 1b) --- needle was found in haystack THIS SHOULD ALSO BE
if ($found === TRUE ) {
echo found is equal to TRUE\n
}
//1c) --- needle was NOT found in haystack THIS SHOULD NOT BE
if ( $found === FALSE ) {
echo found is equal to FALSE\n
}
//1d) --- needle was NOT found in haystack THIS ALSO SHOULD NOT BE
if ($found !== TRUE ) {
echo found does not equal TRUE\n
}
$found = stripos(abcdefg, tuvwxyz);
echo \$found = stripos(\abcdefg\, \tuvwxyz\);br\n
echo The value of found is = : $found\n
//2a) --- needle was found in haystack THIS SHOULD NOT BE
if ( $found !== FALSE ) {
echo found does not equal FALSE\n
}
//2b) --- needle was found in haystack THIS ALSO SHOULD NOT BE
if ($found === TRUE ) {
echo found is equal to TRUE\n
}
//2c) --- needle was NOT found in haystack THIS SHOULD BE
if ( $found === FALSE ) {
echo found is equal to FALSE\n
}
//2d) --- needle was NOT found in haystack THIS SHOULD ALSO BE
if ($found !== TRUE ) {
echo found does not equal TRUE\n
}
the output:
$found = stripos(abcdefg, abcdefg);
The value of found is = : 0
found does not equal FALSE //this is from section 1a) of the code
found does not equal TRUE//this is from section 1d) of the code
// I expected the code from 1b) to be executed
$found = stripos(abcdefg, tuvwxyz);
The value of found is = :
found is equal to FALSE //this is from section 2c) of the code
found does not equal TRUE//this is from section 2d) of the code
I have underlined the output I am interested in... How can the variable $found
be both TRUE and FALSE at the same time?
Anyone who can provide me some insight on this, please enlighten me.
If my code is correct, then this behavior of the === operator is
counter-intuitive, it was my understanding that the === and !== operators were
supposed to be used with the output of stripos() for just this situation, but
=== does not appear to recognize that the returned 0 (because the string was
found at index 0) ; whereas the !== does recognize this...
is === buggy? or am I? heh
thoughts? comments?
Thanks all,
Michael

Does what I want it to when there is no space, regardless of whether
or not there is a pipe. It does not replace anything if there is a
space.
I see your problem -- you're omitting the brackets around your
metacharacters. I believe you should be using [:underscore:] not
:underscore: -- therefore,
/\[([A-Za-z0-9\|\'.-[:underscore:]]+)\]/i
I'm not sure why you need those metacharacters, however; I've never
had trouble matching literal space and underscore characters, e.g. [ _]
Also:
- You don't need to escape the vertical pipe.
- You don't need to escape the apostrophe.
- You do need to escape the hyphen unless you mean it to indicate a
range, which I'm sure you don't here.
On other regexp points:
Thanks, Paul. I've been refining my methods, and I think it's better
(for me) to just match everything between [ and ], including spaces,
underscores, apostrophies, and pipes. I'll explode on the pipe inside
the function.
So I thought that a simple /\[([.]+)\]/i should do it.
Oops: [.]+ will look for one or more periods. .+ means one or
more character of any kind. So you'd want:
/\[(.+)\]/i
In a case like this where you're not using any alphabetic letters in
the pattern, the -i pattern modifier is irrelevant, so I'd drop it:
/\[(.+)\]/
Then your problem is that regexp is 'greedy' and will grab as long a
matching string as it can. If there's more than one of your link
structures in your text, the regexp above will grab everything from
the beginning of the first link to the end of the last. That's why I
excluded the close-bracket in my pattern:
/\[([^]]+)]/
I know [^]] looks funny but the close-bracket doesn't need to be
escaped if it's in the first position, which includes the first
position after the negating circumflex. I've also omitted the
backslash before the final literal close-bracket which doesn't need
one because there's no open bracket context for it to be confused with.
Regards,
Paul

You did??? Where?
How can the variable $found be both TRUE and FALSE at the same time?
None of your output above indicates that it is both equal to TRUE and
FALSE at the same time. It does indicate that $found does NOT equal TRUE
and does NOT equal FALSE at the same time and that is because it
returned the integer value 0 which is the location of the string in the
haystack.
Cheers,
Rob.
