    In many cases, you want to execute a statement if a condition is met, and another statement if the condition is not met. This is what else is. Else runs an if and executes instructions corresponding to the case where the if expression is FALSE. Conditional statements are used to perform different actions based on different conditions.

    I am providing you with an example so that you can understand the concept of else statement :
    PHP Code:
    <?php
    if ($a $b) {
      echo 
    "a is greater than b";
    } else {
      echo 
    "a is NOT greater than b";
    }
    ?>
    Hope that you can also use this statement.

    Instructions after the else are executed if the if expression is FALSE, and if not followed by the expression elseif - only if they evaluated to FALSE. elseif, as its name suggests, is a combination of if and else. Like else, it allows to execute a statement after an if in case the original if expression evaluates to FALSE. But, unlike else, it will execute the instruction that if the elseif conditional expression evaluates to TRUE.

    You can have multiple elseif which follow one after the other after an if statement. Elseif The first to be evaluated to TRUE would be executed. In PHP, you can also write 'else if' in both words and behavior will be identical to the version in one word. The syntactic meaning is slightly different, but ultimately, the result will be exactly the same. Elseif expression is only executed if the preceding if and any preceding elseif expressions evaluated to FALSE, and elseif expression evaluated to TRUE.

    The following is an example of Else If statement, :
    PHP Code:
    <?php
    if ($a $b) {
        echo 
    "a is bigger than b";
    } elseif (
    $a == $b) {
        echo 
    "a is equal to b";
    } else {
        echo 
    "a is smaller than b";
    }
    ?>
    Hope that this sample of coding helps you.!!
