== Why is this an issue?

Having characters before ``++<?php++`` can cause "Cannot modify header information" errors and similar problems with Ajax requests.


=== Noncompliant code example

[source,php]

test<?php  //Noncompliant
// ...

and

[source,php]
----
// Noncompliant; newline before opening tag
<?php
// ...
----


=== Compliant solution

[source,php]
----
<?php  
// ...
