Again, I'm doing this from memory but I'm pretty certain of the function name. phpinfo() is correct, but not needed. Call to undefined function means that PHP was not compiled with this function. Your best bet is to trash the RPM and compile PHP and possibly Apache from the distribution tarball. You can bang you head against various combinations of RPMs for weeks and never find the right combination, or spend a couple hours collecting the requirements and learning to compile the source. Once I got it down I can compile OpenSSL, Apache, ModSSL PHP and all the goodies that go along with it in about 45 minutes, and I don't even have to be there for most of it. I've got a script that compiles it with all the options I chose. I just collect the latest versions, check for new options I might want to use, plug the new version numbers into the top of the script, run it and go find something else to do while it runs.

[PHP] modify an element of a HTML tag within a string
Hi all,
I've asked simular questions before, but I think I'm finally asking the
*right* question to get the right answer.
I'm look for some suggestions on the best method of parsing a HTML document
(or part thereof), with the view of CAPTURING and MODIFYING a specific
element of a specific tag.
something like:
1. look for a given tag eg DIV
2. capture the tag (everything from 'DIV' up to the '')
3. look for a given attribute (eg ID=foo, ID=foo, ID='foo' -- all valid
ways)
4. capture it
5. be given the opportunity to manipulate the attribute's value, delete it,
etc
6. place captured tag (complete with modifed elements) back into the string
in it's original position
7. return to step 1, looking for the next occurence of a DIV tag
I really don't know where to start. I REALLY don't expect someone to write
this for me, just some guidance would be great -- or maybe some inspiration
:)
I guess what I'd like to be able to do, in pseudo code is:
while (getTag('DIV',$myHTML))
{
while(getAttribute('ID'))
{
// manipulate
if($attribute == foo)
{
$attribute == foo2;
}
}
}
while (getTag('DIV',$myHTML))
{
while(getAttribute('ID'))
{
deleteAttribute();
}
}
The solution might be a helluva lot more complex, or may be OOP based.
Any inspiration/links/words of wisdom?

Re: [PHP] Loading a File into Variable - How??
Andre, here's the function that worked for me...
function file_get_contents($filename) {
$fd = fopen($filename, r, 1);
$contents = fread($fd, 12000);
fclose($fd);
return $contents;
}
$page_string = file_get_contents(my_file.php);
The third parameter in fopen() [1] can be removed if you don't want to look
for files in your include_path. The second parameter in fread() [12000] is
where I hardcoded the filesize. Increase that number if you'll be opening
larger files.
Originally I had 12000 replaced with filesize($filename) but if the
$filename was opened from the include_path, this seems to always return
zero, which is why I hardcoded the byte size into fread().

However, I figured out the problem shortly after posting that first message

filesize() doesn't see those files. So, if I replace the
filesize($filename) command with a hard-coded number, it works.

Hi Rasmus,
file_gets_contents() doesn't work in my version of PHP (4.2.1). It says not
a valid function or something like that. Also, I discovered that the
filesize() function won't work on files fopened from the include_path. It
returns a value of zero, so, I had to hardcode the bytes into the fread().

In 4.3 you would use file_get_contents()
In prior versions I would suggest:
$fp = fopen('filename','r');
$string = fread($fp, filesize('filename'));
fclose($fp);
The implode(file()) stuff is very memory-inefficient.

This is probably more of an HTML question... Is there a way to pass variables to another page via POST instead of via the URL? I need to pass several variables, one that is an array and another that is a fairly long string, so, I can't really do this via the URL.

Okay, this is just very general info to help point you in the right direction, but, here are some functions you'll probably need to accomplish this: * Regular Expressions * pregi() and/or eregi() * explode() and implode() * str_replace() Regular expressions will probably be the most important part of doing what you need to do.

7. return to step 1, looking for the next occurence of a DIV tag
If you are only looking for a SPECIFIC tag, you just simplified life
immensely!
?php
# Get some beautiful sample HTML:
$html = file('http://php.net/') or die(Could not open php.net);
$html = implode('', $html);
# Find the DIV tag:
$div = stristr($html, 'div');
$divpos = strlen($html) - strlen($div);
# Break the HTML up into before and after DIV tag:
$before_div = substr($html, 0, $divpos);
$after_div = substr($html, $divpos);
# Find the *END* of the DIV tag:
# KNOWN BUG:
# They *could* bury a in their attributes if they work at it...
$end_tag = strstr($after_div, '');
$endpos = strlen($after_div) - strlen($end_tag);
$div = substr($after_div, 0, $endpos);
# Now get the after part to *really* be after the *WHOLE* DIV tag:
$afterdiv = substr($after_div, $endpos);
echo Before DIV tag: BR, htmlentities($before_div), HR\n;
echo DIV tag itself: BR, htmlentities($div), HR\n;
echo After DIV tag: BR, htmlentities($after_div), HR\n;
?
I can pretty much guarantee that I didn't put a +1 or -1 somewhere where it
belongs in the substr() function calls. I never get that right in my first
pass of coding. You'll have to fine-tune that part yourself.
But you can now do the same technique to search inside of $div for the ID
attribute, pretty much.
The solution might be a helluva lot more complex, or may be OOP based.
Any inspiration/links/words of wisdom?
If you need to do this for any arbitrary tag all at once, there *HAVE* to be
PHP-based HTML parsers out there in the various PHP script archives...
If all else fails, the PHP source for http://php.net/strip_tags must have
some kind of HTML parsing routine in it.

[PHP] Re: Passing variables to page via POST - How?
Hey, I'm new, but I have some advice. Do you have to POST? becuase you can use sessions, and PHP has a bunch os session functions. Secondly, POST will not attach any variables to the URL, this is done by GET. To access the POST variables traverse through the $HTTP_POST_VARS (or $_POST array, i think) to retrieve your values. But if you can try using sessions, more secure, and as easy to use as POST, just traverse $HTTP_SESSION_VARS. Monty [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

Re: [PHP] Password in script
Ok I am going to give out my little secret that was passed to me. Your
worry is warranted in my opinion especially since let's say your isp is in
the middle of an upgrade or something happens to php that breaks it.. Now
your php code is being shown as regular text.. Anybody can see your code.
There are a lot of things that could possibly go wrong.. Maybe an error
happens and it shows where you have the error and it shows your username and
password.. So many things.. So use an external file that is below your
htdocs/www/public_html directory. I usually use a directory called
phpinc/php_inc/php. Call it whatever you want :) and then put a file in it
called say.. query.inc
query.inc
?
function queryDB ($query) {
$connect = mysql_pconnect('host', 'username', 'password');
$result = mysql_db_query('database',$query,$connect);
if ($result) {
return $result;
} else {
echo h1Error in Query/h1;
echo Query: \$query\br /;
echo mysql_errno($connect).: font
color=\red\.mysql_error($connect)./fontbr /;
exit;
}
}
?
Include this file within any file that will be doing database queries. Then
whenever you want to make a call to the database use this syntax:
$result = queryDB(YOUR SQL QUERY HERE);
Plus it will show you where you are getting your mysql errors when you have
them. It's a great little function.. Thank you John Ash! :) Gotta give
credit where it's due :)
I hope it helps!
Cheers!

echo $k[0] = $v\nbr;
}
will list all the $k $v .
a = foo
a = bar
b = another foo
...
and so on
Now, how can i sort it according to $k[0]
where $k[0] = a, than the same for all b's and so on.

RE: [PHP] Sorting array based on key string
dunno if this'll work... but here goes...
sort($data);
ksort($data);
but ksort() might mangle the order from sort(). In that case, you'll need to
write your sort routine that retains the old order

Subject: [PHP] Sorting array based on key string
Pardon my sloppy explanation but here it is:
how can i sort an array based on key element ie.
key values are: a1, a2 ,a3 ..., b1, b2 ,b3, ...c1, c1, c3...
so doing this:
while (list($k, $v) = each($data)) {
for ($i=0; $icount($k); $i++) {
echo $k[0] = $v\nbr;
}
will list all the $k $v .
a = foo
a = bar
b = another foo
...
and so on
Now, how can i sort it according to $k[0]
where $k[0] = a, than the same for all b's and so on.

RE: [PHP] best way to delete char# 4-7 from a string?
dunno how much slower it'd be, but it might look better. You could convert the strings to an array, use array_splice(), and then convert back to a string. -Original Message- From: Justin French [mailto:[EMAIL PROTECTED]] Sent: Friday, July 19, 2002 3:39 PM To: php Subject: [PHP] best way to delete char# 4-7 from a string? Hi, Let's say I have the following string: $str = 'abcdefghijklmnop'; ...and I want to strip out char #'s 4 through to 7 (d,e,f,g) $strip_start = 4; $strip_end = 7; ($str would now be 'abchijklmnop';) THEN I want to plug a new string $filler at position 4 $filler = '4567'; ($str would now be 'abc4567hijklmnop') This is what I think would work (untested), looking for pointers, optimisation, or a better approach: ? $str = 'abcdefghijklmnop'; $strip_start = 4; $strip_end = 7; $filler = '4567'; $pre = substr($str,0,$strip_start-1);// abc $post = substr($str,$strip_end+1,strlen($str)); // hijklmnop $str = $pre.$filler.$post; //abc4567hijklmnop ?
