hjælp til dato og tid i chat..
Hejsa..Jeg har ingen forstand på PHP, men bruger en chat i php på min hjemmeside, med dagligt 10 brugere der skriver kommentat i chatten.
Jeg kunne godt tænke mig der blev gemt tid og dato sammen med teksten, så de få, men trofaste brugere kan se hvornår en kommentar er tilføjet chatten.
Hvem kan hjælpe mig med dette.. ?

// a) Adjust the configuration variables to your needs
$file = "shouts.txt"; // Name of the file which
// contains the shouts
$shouts = 20; // Number of shouts to be displayed
$maxlength_name = "20"; // Maximum length of name
$maxlength_text = "250"; // Maximum length of text
$break_name = "15"; // Break name after characters
// without space
$break_text = "15"; // Break text after characters
// without space
// b) Copy this code to your PHP file
// c) Copy your PHP file and the shouts file defined in
// variable $file to your server using ASCII mode
// d) Make the shouts file writable (Windows: adjust
// security, Unix: chmod 777)
