I haven't had a need for something like this myself, but I think the
ignore_user_abourt() function is what you need:

[EMAIL PROTECTED] (Chris W. Parker) writes: > 2. you cannot create/write a session value after you send any html > output to the client. That's not entirely true --- you just have to call session_start() before any HTML output is sent to the browser, for session_start() must be able to set the session cookie (if using session cookies that it). The very first example here illustrates this: http://php.net/session-start There the session_start() is called, then some output is sent to the browser, and later the three session variables 'favcolor', 'animal', and 'time' is set. The session variables can be set and updated at any time because this only associates data with the session on the server side. -- Martin Geisler My GnuPG Key: 0xF7F6B57B PHP EXIF Library | PhpWeather | PhpShell http://pel.sf.net/| http://phpweather.net/ | http://gimpster.com/ Read/write EXIF data | Show current weather| A shell in a browser -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Your idea sounds good, and luckily you don't have to build your own random generator, behold: http://php.net/rand Then call rand() with two arguments: the minimum and maximum ID, and it will give you a random integer back between those two numbers. You could also opt to have MySQL make the random number for you, and then do a query like SELECT * FROM table ORDER BY RAND() LIMIT 1; Then you wont have to deal with figuring out the number of rows in the table as you would in the PHP case. You can also increse the limit to, say, 3 and then show three random quotes on your pages. See http://dev.mysql.com/doc/mysql/en/Mathematical_functions.html#IDX1363 for a description of RAND() in MySQL. -- Martin Geisler My GnuPG Key: 0xF7F6B57B PHP EXIF Library | PhpWeather | PhpShell http://pel.sf.net/| http://phpweather.net/ | http://gimpster.com/ Read/write EXIF data | Show current weather| A shell in a browser -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

My PHP manual (from a Debian package) has the following note on the page for round(): Caution When rounding on exact halves round() rounds down on evens and up on odds. If you want to always force it in one direction on a .5 (or .05 in your case) add or substract a tiny fuzz factor. The reason behind rounding half the values down and the other half up is to avoid the classical banking problem where if you always rounded down you would be stealing money from your customers, or if you always rounded up you would end up over time losing money. By averaging it out through evens and odds you statistically break even. -- Martin Geisler My GnuPG Key: 0xF7F6B57B PHP EXIF Library | PhpWeather | PhpShell http://pel.sf.net/| http://phpweather.net/ | http://gimpster.com/ Read/write EXIF data | Show current weather| A shell in a browser -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
