Re: [PHP] Association Problem?

Wanted to see if anyone had any input on this. I have a recordset that

to sort display the recordset based on how many times the string
appeared in each row.
Basically this is a very light search with a very quick dirty way to
find relevancy. I've thought that I could just store the relevancy
numbers in an array, but then how do I know which relevancy number goes
with what row in the recordset? That's the association problem I'm
talking about. Also, how would I then sort the recordset accordingly
based on the relevancy array?
I've been looking through the PHP documentation and can't quite get past
this question. Anyone have any ideas? Thanks!
try array_multisort():
$search_str = 'abc';
$sort_array = array();
foreach ($recordset as $k = $v) {
$sort_array[$k] = substr_count($v, $search_str);
}
array_multisort($sort_array, $recordset);

don't know how you can get around that with ereg.
also preg_replace('/!--.*?--/s', ...) is much faster. :-)

It's not a matter of escaping. You're matching too much with the .*.
If you're sure you won't have any right-point-brackets inside comments,
you can use something like:
$text = ereg_replace(!--[^]*--,,$text);
Accurately matching comments in an extended regular expression is tricky
though. The only thing you can really *negate* in an ereg is a range,
not an atom. And the close of the comment can't be prepresented as a
range, since it's multiple characters.
Not to say it can't be done. I just can't think of how at the moment.
you can make the .* less greedy...
$text = preg_replace('/!--.*?--/', '', $text);

Interesting to know. My preg-foo is limited; I came at PHP from a
background of awk and sed, so when I regexp, I'm a little more
traditional about it.
Interestingly, from a shell:
$ text='one !-- bleh -- two\nthree !-- blarg --four\n'
$ printf $text | sed -E 's/!--([^-][^-]?[^]?)*--//g'
one two
three four
which is the same behaviour as PHP. But that still doesn't cover
multi-line. PHP's ereg support is supposed to, but doesn't work with
this particular substitution:
$text=one !--bleh\nblarg - two\n;
print ereg_replace(!--([^-][^-]?[^]?)*--, ,$text);
returns
one !--bleh
blarg - two
But we know it really does support multiline, because:
$text=bb\nbb;
print ereg_replace([^ac],,$text);
returns
So ... this is interesting, and perhaps I'll investigate it further if
the spirit moves me. ;-)
right, to strip multi-line comments with preg_replace you need /s
$text = preg_replace('/!--.*?--/s', '', $text);

Hi!
Got this script:

The output is:

Q | R | S | T | U | V | W | X | Y | Z |
AA | AB | AC |
...
YX | YY | YZ |
where is should display only letters from A to Z.
Why is that?
Because 'Z'++ (if you see what I mean!) is 'AA'.
(So, at the end of the loop iteration which echoes 'Z', $i becomes 'AA',
which is 'Z', and as a result the loop continues on through all
the values
you saw. The loop terminates after 'YZ' is echoed, since at the
end of that
iteration $i increments to 'ZA', which is not 'Z', and Bob's your uncle!)
One way of solving this is:
for ($i='A'; $i!='AA'; $i++)
Cheers!

Once again it would probably be easier to just lay out a DB schema! it looks like array_multisort() will sort one array based on a sort of another... so you could do something like // create an array of titles that can be sorted foreach ($a as $k = $v) $titles[$k] = $v['title']; // sort $titles, then sort $a like $titles array_multisort($titles, $a); - rob -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I made small kicking system for those who tried to guess the Login
information.
The script below is just a part of the code, but it's not working properly.
I tried to solve this problem in many ways, but I couldn't.
This script should check if the visitor's IP is listed in log.txt file and
if it is, the warning appears.
But the problem is that the script checks only first line in the log.txt
file, not all the lines.
P.S.
log.txt file has many IP addresses listed in one column.
$ip = getenv (REMOTE_ADDR);
function kick() {
$file_ip = file(log.txt);
foreach($file_ip as $value_ip ) {
$kick .= $value_ip;
}
return $kick;
}
if ($ip == kick()){
echo Sorry, the access is denied.;
exit;
}
I think you want something like:
if (in_array($_SERVER['REMOTE_ADDRESS'], file('log.txt')))
die(Sorry, the access is denied.);
