For Linux it is easy, just read the /proc/uptime file:
$uptimevalues = file("/proc/uptime");
The first value from /proc/uptime is the uptime, the second is the idle
time for the cpu.
NT is harder. I don't know anything about that.

Create a php script that reads the file and feeds it to the user. In that script you can have some intelligence like referrer-checking, and you should also give the user a correct mime-type for that file in the http-header. -- patrik_wallstrom->foodfight->[EMAIL PROTECTED]>+46-709580442 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

This is exactly the reason you should use a specific standard hash algorithm like MD5 or SHA-1 when encrypting passwords. The PHP crypt() call uses the system call crypt(), which might vary between different systems. Look at the PHP man pages for crypt() and the mcrypt package for more info on the subject. With mcrypt you can use whatever crypto function you need for compatibility. http://www.php.net/manual/en/function.crypt.php http://www.php.net/manual/en/ref.mcrypt.php -- patrik_wallstrom->foodfight->[EMAIL PROTECTED]>+46-709580442 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

I'll see what I can do. If you really really need STD_DES for PHP 4.1, check the source code in ext/standard/crypt.c and force it to use STD_DES and recompile. >From crypt.c: /* The capabilities of the crypt() function is determined by the test programs run by configure from aclocal.m4.

If you have some documentation for the ISP you are using, that would be a lead...

It is not an operator, it is how you reference objects in php. $this is the object that you are current using, and you are referencing the objects variable $file with $this->file.

What you have done here is that you have added an array to your array, but
you wished to have the value added to your array. The $MyArray[] pushes a
new value to the array, in this case another array. You want
$MyArray['BUYVAL'] = 1.23.

[PHP] optimizing mysql with php
What settings should I have if I would like to optimize PHP without exhausting my MySQL db? There is the mysql.max_persistent setting, which is on a per process level. Should I set this low, to 10 perhaps? If it's unlimited, PHP will just eat up another persistent connection until MySQL is exhausted. If I lower it, PHP will reuse the old ones. I have set the MySQL setting to set-variable= max_connections=255 which should not be succeeded. MaxSpareServers is 25 in my Apache. Which should result in the 10 setting for PHP, right? Since 10*25 = 250. Is this the correct reasoning behind this setting? Are there any other Apache/PHP-related settings I should think about? -- patrik wallstrom | system design tel: +46-8-7298810 | sonox.com gsm: +46-708405080 | - - - - - - - - - fax: +46-859820060 | a division of new media distribution -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
