PHP else if ladder
PHP else if ladder :-
PHP If ladder is a specific kind of nested if statement, where nesting only occurs in the else part. This statement is useful when an action needs to be chosen depending on a range of values.
PHP, an “else if ladder” (also known as a “chain of if-else statements”) is a construct that allows you to evaluate multiple conditions in sequence. It’s particularly useful when you want to check different conditions one after the other and execute specific code blocks based on the first true condition encountered.
Syntax :-
statement;
if (condition)
{
statement;
statement;
}
else if (condition)
statement;

}
