because an elseif statement isn't check if the if statement is True like if (1 == 1) { echo 1; } elseif (2 == 2) { echo 2; } return 1 and if (1 == 1) { echo 1; } if (2 == 2) { echo 2; } return 12

you need elseif statement if you have more than two condition in your code.

U can also use switch instead of elseif. It is much more efficient

I can give you examples, but u wont be satisfied, because switch compares the variable with every individual value that it can hold, and the code will be extremely tedious to write if the variable has to be checked within a large range. In that case elseif serves the purpose much more efficiently and cleanly.

Eg. if(marks<30) echo fail; else if(marks>=30 && marks<50) echo pass; else if (marks>50) echo good;

Switch only works more efficiently if the variable is compared with a small no. of values, otherwise in all cases elseif is better

multiple if's are costlier than elseif.
