[PHP] ob_start callback preg_replace
Can someone help me with preg_replace?
I want to convert all numbers either 8 or 9 digits in length, into a
link. Such that when it sees:
John Doe, 456890123, is a new employee.
It converts it to:
John Doe, 456890123, is a new
employee.
function callback($buffer) {
// create id links
return ???;
}
ob_start("callback");
Thanks much,
John

[PHP] Re: clearing new pages
I put this at the top of long pages,
$processing = "
processing, please wait ...
";
echo $processing;
flush();
Then put this at the bottom,
$hide = "
if (document.layers) {
processing.visibility='hide'
} else if (document.all) {
document.all('processing').style.visibility='hidden'
} else {
document.getElementById('processing').style.display='none'
}
";
echo $hide;
Works pretty good.

a file called a.php prints "hello" to the browser then calls b.php
which prints "goodbye" to the browser.
the output looks like this:
hello
goodbye
how do I clear the screen so the end results looks like this:
goodbye

[PHP] Re: Perfect Squares
Try taking the square root of the variable
$sqrt = sqrt($var);
then compare the number of decimal places.
if (strlen(strstr($sqrt,".")) <= strlen(strstr($var,"."))) {
// perfect
}
Just guessing of course.

I'm in a bit of a pickle. I need to find out if a variable is a perfect
square or not, and this needs to test for decimal numbers as well, such as
2.25. The thing is, the only function I've found in PHP is
gmp_perfect_square() which isn't supported on my web server, and I don't
know how to compile the GMP code into PHP on my windows box. So, how exactly
would you go about finding out if something is a perfect square or not?

[PHP] Re: multi array wildcard
I went ahead and just wrote a quick function. If there is an easier
way, please let me know. Thanks.
function multi_pick($multi_array, $return_key) {
$ret_array = array();
foreach ($multi_array as $key=>$sub_array) {
if (isset($sub_array[$return_key])) {
$ret_array[$key] = $sub_array[$return_key];

return $ret_array;

[PHP] multi array wildcard
Is there a shortcut way to turn an subelement in a multi-dimensioned array into a regular array. For example, here's my array: // print_r($users) Array ( [1] => Array ( [name] => John [email] => [EMAIL PROTECTED] ) [2] => Array ( [name] => Chuck [email] => [EMAIL PROTECTED] ) ) I'd like a quick conversion for the names to Array ( [1] => John [2] => Chuck ) Something like $users[*]['name'] Thanks, John -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I am relatively new to PHP. But something I can't seem to make work is when
I call one of the functions I have made and a variable is set inside that
function
eg. function blah ($bl,$ah) {
$bl++;
$ah++;
$blah=$bl+$ah;
}
I then echo $blah; somewhere else in the script but nothing is echo'd. How
do I make it so that I can use $blah anywhere in the script?
Thank you in advance for any help.

[PHP] Re: syntax help
If you want to actually want the variables $flyertotal, $emailtotal, and
$phonetotal, use the line:
${$array[0]."total"} = $row[0];
But as you defined $array, that will actually create the variables
$Flyertotal, $Emailtotal, and $Phonetotal (note the caps).
On 2/13/2004 6:10 AM, Bob pilly wrote:
$array[$i].total=$row[0];<-- problem here
so for the above code i would like to create three
variable $flyertotal,$emailtotal & $phonetotal

Re: [PHP] update password cookie
I'm just storing its hash. Then comparing it to the database hash. Is that bad? Is there a good write-up somewhere discussing authentication techniques that you could recommend? Yahoo makes you reenter your password every time you reopen your browser. I'll check other sites though. Thanks for the advice.

[PHP] update password cookie
When my users log in, they enter their username and password, and click a checkbox to remember the login in the future. If the remember checkbox is left unchecked, the cookie expire is set to zero. I also have a page where they can change the password. My question is - how do I update the password cookie without having to ask whether or not they want to remember it again? How can I find out when the current cookie expires? Thanks, John -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Hi
Can anybody help me grasp multidimensional arrays please? Basically, I am
retrieving all records from one table (two fields), and want to return them
in an array.
I am converting code from ASP to PHP, and in the former I did something like
this:
select id, name from customer
redim custarray(recordcount,2)
i = 0
while not eof
custarray(i,0) = id;
custarray(i,1) = name;
i = i+1;

wend
... but all my efforts to store them in the same kind of way in PHP have
proved fruitless. Any advice would be much appreciated.
Many thanks
