No, but it can be done in one line:
?php
echo array_rand(@file(@$filename), 1);
# if you wanted to do a couple checks, you could do the following
if ( is_file(@$filename) filesize($filename) 0 )
echo array_rand(file($filename), 1);

This method will eat memory unless you have a very small file.
Personally I would use filesize to get the length of the file, fopen it, fseek
to a random position, then track back to a newline and use fgets to get the
line. Then fclose, obviously.
Simples.

Hi.
I just wanted to quickly see if PHP supported ranges in its
switch/case statement (http://en.wikipedia.org/wiki/Ellipsis)
?php
$s = intval(date('s'));
switch($s)
{
case 0...9 : echo 'Between 0 and 9'; break;
case 10...19 : echo 'Between 10 and 19'; break;
case 20...29 : echo 'Between 20 and 29'; break;
case 30...39 : echo 'Between 30 and 39'; break;
case 40...49 : echo 'Between 40 and 49'; break;
case 50...59 : echo 'Between 50 and 59'; break;
default : echo 'Unknown : ', $s;
}
?
Completely unexpectedly, the above code runs but produces the wrong output.
Interestingly, altering the number of dots and adding spaces all
result in parse errors ...
case 0..9 : // 2 dots, no spaces
case 0 .. 9 : // 2 dots, with spaces
case 0 ... 9 : // 3 dots, with spaces
It was confusing that the initial code ran without a parse error, but
considering that it did, it would suggest that the case values are
actually meaningful in some way.
php -r var_dump(10...19);
Interesting output ...
string(6) 100.19
And that took me a little while to work out.
It's all to do with PHP's type juggling.
10...19
What I'm not sure is why the middle empty string is output as 0.
10 . . .19 becomes 10 . 0 . .19 which becomes 100.19
Oddly, more . don't work.
php -r var_dump(1019);
all result in parse errors.
I don't know if this is a bug per se, but it is an oddity that I
though I'd share.
And what is even more surprising is that the initial code works in the
PHP V4.0.0. So maybe an 11 years old bug.
You really would have thought I'd have more to do with my time!
Regards,
Richard.

[PHP] Newbi Question with calculate
Hello, i have write a script for my Stock portfolio and now im not really find something which can me help. In the table php calculate me the Present Value and the Percent with this code: ?php //Quantity $ABEI = 240; //Buy Quote $KKBEI = 41.31; //Buy Balance $KWBEI = 9914.40; //calculate include(../inc/quote.php); // Yahoo Quotes $BEIERG = $KKBEI*$ABEI; // Buy Balance $BEIDW = $BEIQuote['last']*$ABEI; // Present Value $BEIAEN1 = $BEIQuote['last']-$KKBEI; // Quote Win $BEIAEN = $BEIAEN1*100/$KKBEI; //Percent Win ?

I think you want to use the FOR loop to process each record in your table. You query (?) the table and then process each row in the result using the FOR and all your calculations on each one.

I will give you a mysql example. Apply the logic to the table during the query so you can just loop over the results like such. $ABEI=12; $query = ' select last * '.$ABEI.'

Re: [PHP] Newbi Question with calculate
Hello, sorry i has not correct write. The example when is finish can see at http://silviosiefke.de/finance/stock/stock.php For this i not use a mysql Database, its normal not so much at data. I have write the source as Text Files: http://silviosiefke.de/finance/finished/txt/index.txt - That is the Start Page. The included Files: http://silviosiefke.de/finance/finished/txt/include.txt - Yahoo API http://silviosiefke.de/finance/finished/txt/quote.txt - Yahoo Symbols http://silviosiefke.de/finance/finished/txt/variable.txt - Calculate If I calculate all the shares in my portfolio, then I have to create for each share a file variable.php. Thats little long, is not the problem i make it, but i think there is a chance to use the file variable.php at moment for all what come in my portfolio? For example at Moment i calculate Beiersdorf AG, the next in Portfolio is Deutsche Bank AG. Now i must write a new variable.php for Deutsche Bank. Or is there a chance that i can write one variable.php for all Shares what i take in the portfolio. Sorry for my english, i know its not perfect. Hope all can understand what i mean. I learn every day and i find good that i not must use google since few weeks. Thanks for help, have nice day at all.

[PHP] File Upload Problem
Hi gang: I wrote a simple script to upload image files from my desktop to a server -- the exact same code works on two servers, but fails on a third. I suspect there is something set different between the servers, but I can't find it. Oddly enough, I can upload image files directly to the database, but not to the file system. What could be wrong? What should I be looking for? Cheers, tedd -- --- http://sperling.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

What should I be looking for? Are file uploads enabled and is the size of the file less than the upload size limitation? Is the disk or partition to which the temporary files are being uploaded out of space, whereas the database - perhaps on a different physical disk or partition - still has sufficient free space? Are you sure the user as which the web server (presumably Apache) runs has permission to write to the temporary and target directory? Is the account near or at its disk quota? -- /Daniel P.

[PHP] openssl question
Hi,
i try to create a self signed certificate using this code:
?php
if(!isset($_GET['password']))
{
echo Error Code: 1;
exit(1);
}
if($_GET['password'] == )
{
echo Error Code 2;
exit(1);
}
$password = mysql_real_escape_string($_GET['password']);
$dn = array(
countryName = DE,
stateOrProvinceName = test,
localityName = test,
organizationName = test,
organizationalUnitName = test,
commonName = test,
emailAddress = t...@test.de
);
$privkey = openssl_pkey_new();
$csr = openssl_csr_new($dn, $privkey);
$sscert = openssl_csr_sign($csr, null, $privkey, 365);
openssl_csr_export($csr, $csrout) and var_dump($csrout);
openssl_x509_export($sscert, $certout) and var_dump($certout);
openssl_pkey_export($privkey, $pkeyout, $password) and var_dump($pkeyout);
while (($e = openssl_error_string()) !== false) {
echo $e . \n;
}
?

I've recently reread (most of it anyway) K R, and the whole time I was reading I felt like I was studying up on PHP just as much as C. There's no language that played a bigger role in the design decisions, and this is clearly evident when you listen to the core developers. In fact, even this past week Rasmus said on the PHP Dev list, Argh! Everyone should be forced to learn a bit of C. Like many PHP functions, the name and argument order is right out of libc, a sentiment he's expressed before. I must admit that I tend to think of PHP as C code that includes garbage collection of lots of very practical web goodies. And, the book itself is a gem in terms of clarity, brevity, and sage advice. So, read (or read again for the umpteenth time) K R, and then fill in the gaps with PHP.net. And, on the rare occasion you would need more speed than your PHP script is providing, you'll be able to write you're own extension to PHP using it's older brother, C.
