Naming a text file as a variable

[pali]

Hey guys, i have a variable \[code\]$Date\[/code\] that is automatically updated each day. I would like to create a new text file each time that there is a new entry. So basically every day. I would like to use \[code\]fopen\[/code\] to create a new text file every time a user submits a value, but only for that day. If a user creates another account the next day, it will be a new text file with that date for a name...I only have three variables, \[code\]$date\[/code\],\[code\]$Name\[/code\], and \[code\]$number\[/code\]is it possible to create this as follows?\[code\]$textmember = "$date.txt"\[/code\]thanks!
