As posts get their data set up via the_post() (respectively via setup_postdata()) and are therefore accessible through the API (get_the_ID() for e.g.), let’s assume that we are looping through a set of users (as setup_userdata() fills the global variables of the currently logged in user and isn’t useful for this task) and try to display … Read more
perldoc perlvar is the first place to check for any special-named Perl variable info. Quoting: @_: Within a subroutine the array @_ contains the parameters passed to that subroutine. More details can be found in perldoc perlsub (Perl subroutines) linked from the perlvar: Any arguments passed in show up in the array @_ . Therefore, if you called a function with two … Read more

You should use double quotes for string lliteral, and you are wrongly declaring the array. Perhaps you are looking for thiss.
Numeric defines the TOTAL number of digits, and then the number after the decimal. A numeric(3,2) can only hold up to 9.99.
Quick review, DB – Define Byte. 8 bits DW – Define Word. Generally 2 bytes on a typical x86 32-bit system DD – Define double word. Generally 4 bytes on a typical x86 32-bit system From x86 assembly tutorial, The pop instruction removes the 4-byte data element from the top of the hardware-supported stack into the specified operand (i.e. register or … Read more
You can declare an array only with constant size, which can be deduced at compile time. zo1,zo2 and zoA are variables, and the values can be known only at runtime. To elaborate, when you allocate memory on the stack, the size must be known at compile time. Since the arrays are local to the method, they will be placed on the stack. You … Read more
I think you should move the variable declaration to top of block. I.e. to
Null OR an empty string? Use empty(). After realizing that $user ~= $_POST[‘user’] (thanks matt):
Reducing to three lines (the other errors are analogous): While wall is defined, gallons is not. And where do you want to get gallons from anyway? The result is hidden deep inside another function. How do you want to get it out from there? Well, you need a return value: This way, you can use your function like this: Analogously for … Read more
