Answer 2

1-function NAME($variables, $ofthings, $being, $passed)
{

stuff to do
return($if anything);
}


2- NAME($variables, $ofthings, $tobe, $passed);

3- return($value);

4- return($anything); or return();
}

5- 0

6- statements require ; at the end... php starts with

7- yes... $num = 123; $num .= 456;

8- no, if it is true it will execute either from { to } or only the next line. It is not REQUIRED but good practice to use it regardless

9- if ($a == $b)
{
do stuff
}

10- if($a == $b)
{do stuff}
else if ($a == $c)
{do stuff}
else
{do stuff}

11- $variable

12- if ($a == $b) or ($a != $b) does not equal

13- /* comments */ for multi line or # for single line

14- I've done enough of your homework.

Answer 3

10 if($a == $b)
{do something}
else if ($a == $c)
{do something}
else
{do something}
