PHP Nested if

Nested If

You can place if statements within other if statements, which are known as nested if statements.

Example

An if statement within another if statement:

$a = 13;

if ($a > 10) {
  echo "Above 10";
  if ($a > 20) {
    echo " and also above 20";
  } else {
    echo " but not above 20";
  }
}
