Want to know how to change the alert box title in javascript...
the answer is: we cant change the title of js alert box.
however, we can use popup boxes, that look like alert boxes with custom title.... but there is a chance - some browsers will block that.
Or we can use vbscript msgBox, but cant get the result in FF.
Or we can use custom designs like this:
http://www.acejs.com/scriptsfolder/121015/121015.html
BUT it is not working like exactly as a alert box. (following codes will get executed though we dont click the ok button)
My opinion: Its better not to use any other custom alert boxes.

Change / Increase session timeout in php
Projects using login may have the problem of expiring sessions in short time.
How to increase the session timeout in PHP?
use this as first line - before session_start
ini_set('session.cookie_lifetime',(3600*2));
In some servers it may not work.... BUT using .htaccess file it is working very fine.
Just place these lines in the .htaccess file and put the file in your root directory.
php_value session.cookie_lifetime 3600
php_value session.gc_maxlifetime 3600
and note these parameters are in seconds.
Then how to check the current session timeout?
use this:
printf("cookie: %s, gc: %s", ini_get('session.cookie_lifetime'), ini_get('session.gc_maxlifetime'));
Thats all.

Random Number / Alpha Numeric Password Generation in PHP
To generate random no.s we can use rand() function...
try,
echo ran() ; //will generate random no between 0 and32768
echo rand(5,200); //a random no between 5 and 200
To generate alpha numeric random no - uniqid()...
try,
echo uniqid(rand(), true);
you can get a number like: 274134886dbd37292e8.16885304 (32 digit)
To generate alpha numeric passwords for user accounts use this:
$password = substr (MD5(uniqid(rand(),1)), 3, 10); //10 digit random alpha numeric password
Reference:

Saving Textarea value with enter / Line feed / Line break in PHP
In save forms into database... the value in the text area cant be saved with the line feed that user gives.
To get them we can use the following function...
consider the textarea name is description.... then we can convert the line feed in the form of '\n' or '\r' into <br />
$desc = $_REQUEST['description'];
$desc = ereg_replace("(\r\n|\n|\r)", "<br />", $_desc);

Call Functions across parent and child windows using iframe
Div over flash problem in HTML
Some may have this problem.
Always the flash object looks like placed in front of all the objects. So if we want to put a div in front of flash/ over flash we cant.
But there s a solution...
The normal flash object....
<object classid="clsid:D27CDB6E-AE6D-11CF-96B8-444553540000" id="obj1" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0" border="0" width="519" height="255">
<param name="movie" value="center_flash.swf">
<param name="quality" value="High">
<embed src="center_flash.swf" pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash" name="obj1" width="519" height="255" quality="High">
</object>
To make it back of all elemnts add
<param name="wmode" value="transparent">
So the actual code we want is...
<object classid="clsid:D27CDB6E-AE6D-11CF-96B8-444553540000" id="obj1" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0" border="0" width="519" height="255">
