== Why is this an issue?

The `elseif` keyword is preferred over the `else if` keywords in PHP due to its consistency with other programming languages.

`elseif` is a single token, making it more efficient for the PHP parser to process. Additionally, using `elseif` encourages developers to follow a unified coding style and maintain a consistent syntax throughout their PHP codebase.

Overall, the use of `elseif` improves code clarity, reduces potential errors, and enhances the overall maintainability of PHP projects.


=== Noncompliant code example

[source,php,diff-id=1,diff-type=noncompliant]
----
if ($expr1) {
  ...
} else if ($expr2) {
  ...
} else {...}
----


=== Compliant solution

[source,php,diff-id=1,diff-type=compliant]
----
if ($expr1) {
  ...
} elseif ($expr2) {
  ...
} else {...}
