=== Code examples

==== Noncompliant code example

[source,php,diff-id=1,diff-type=noncompliant]
----
if (($val = value()) && check()) { // Noncompliant
}
----

[source,php,diff-id=1,diff-type=compliant]
----
$val = value();
if ($val && check()) {
}
----
or 

[source,php,diff-id=1,diff-type=compliant]
----
if ($val == value() && check()) { // Original intention might have been to use equality operator and not assignment
}
----
