Str =" ";

Reference: Do not enclose strings in quotation marks?

Output $ qgmw [0] to see what it is.
Or use the complete syntax var str =' ';

The string is added with "", the array will [], and the object will {}

Reference:

$ Time = date ("Y, m, d ");
$ Mday = date ("D ");
// Var_dump ($ mday );

If ($ mday = 'mon') $ mday = "Monday ";
Else if ($ mday = 'tue ') $ mday = "Tuesday ";
Else if ($ mday = 'wed') $ mday = "Wednesday ";
Else if ($ mday = '......

Paste the executed HTML code.
We can't run it if you paste it to php.

Or you can use firebug to troubleshoot the error.
