Trouble with While()
 
I have a script with the following code because I couldn't get a while loop to work...

Code:
        $timespan = 'thread.dateline<UNIX_TIMESTAMP(CURDATE()) AND thread.dateline>UNIX_TIMESTAMP(CURDATE()-1)';
        construct_newsdays();
        $timespan = 'thread.dateline<UNIX_TIMESTAMP(CURDATE()-1) AND thread.dateline>UNIX_TIMESTAMP(CURDATE()-2)';
        construct_newsdays();
        $timespan = 'thread.dateline<UNIX_TIMESTAMP(CURDATE()-2) AND thread.dateline>UNIX_TIMESTAMP(CURDATE()-3)';
        construct_newsdays();
        $timespan = 'thread.dateline<UNIX_TIMESTAMP(CURDATE()-3) AND thread.dateline>UNIX_TIMESTAMP(CURDATE()-4)';
        construct_newsdays();
        $timespan = 'thread.dateline<UNIX_TIMESTAMP(CURDATE()-4) AND thread.dateline>UNIX_TIMESTAMP(CURDATE()-5)';
        construct_newsdays();
        $timespan = 'thread.dateline<UNIX_TIMESTAMP(CURDATE()-5) AND thread.dateline>UNIX_TIMESTAMP(CURDATE()-6)';
        construct_newsdays();
        $timespan = 'thread.dateline<UNIX_TIMESTAMP(CURDATE()-6) AND thread.dateline>UNIX_TIMESTAMP(CURDATE()-7)';
        construct_newsdays();
        $timespan = 'thread.dateline<UNIX_TIMESTAMP(CURDATE()-7) AND thread.dateline>UNIX_TIMESTAMP(CURDATE()-8)';
        construct_newsdays();
Now, the code I'd like to use but can't get to work

Code:
$counter = "0";
while ($counter<=7)
    {        $timespan = 'thread.dateline<UNIX_TIMESTAMP(CURDATE()' . $counter . ') AND thread.dateline>UNIX_TIMESTAMP(CURDATE()-' . $counter-1 . ')';
    construct_newsdays();
    }
Any ideas (yes, I do feel like a complete n00ber for not being able to get a loop to work).

A for loop is preferable when you know how many iterations you need.
PHP Code:
for ($i = 0; $i < 7; $i++)
{
    // your code
}

Thanks. I'll try it out later this week (Getting late now, don't want to start coding tonight and go back to work tomorrow).

This should be correct:

PHP Code:
$counter = "0";
while ($counter<=7)
    {     
    $timespan = 'thread.dateline<UNIX_TIMESTAMP(CURDATE()' . $counter . ') AND thread.dateline>UNIX_TIMESTAMP(CURDATE()-' . $counter-1 . ')';
    construct_newsdays(); 
    $counter++;
    }
