How does “do something OR DIE()” work in PHP?

by

If the first statement returns true, then the entire statement must be true therefore the second part is never executed.

For example:

$x = 5;
true or $x++;
echo $x;  // 5

false or $x++;
echo $x; // 6

Therefore, if your query is unsuccessful, it will evaluate the die() statement and end the script.
