This is a problematic code ...
Replace empty () with isset () ...
Otherwise there will be notice ...

Use the ternary operator, which is the statement ? : ; , to determine whether it is empty with empty

A bunch of variables are empty, not empty spaces

? : This operator you get to know

This is the code that gets the data from the Post's form data.
The main meaning of the first line of the null check is that if the taste in the _post array is empty $taste the variable is assigned 1 otherwise the form data
The other code is pretty much the same thing. Implode is to pass over the string, split the cut into groups

Like XX? The format of the A:B is called the three-mesh operator

$v =empty (xxxx)? A:b

$V is a variable
= number is an assignment character
Empty (xxxx)? Equivalent to a judgment. Empty is a function that determines whether it is null
If xxxx is empty the value of $v is assigned a
If XXXX is not empty then the value of $v is assigned to B
