rspec/rules/S2048/php/rule.adoc

== Why is this an issue?

Shared coding conventions allow teams to collaborate effectively. 


This rule checks that when 

* an assignment is too long to fit on one line, the line break is inserted before the ``++=++`` rather than after, and the second line of the statement is indented from the first. 
* an object operator is the first thing on the line, it is indented from the previous line.


=== Noncompliant code example

[source,php]
----
$variable_with_a_very_very_long_name = classInstance.method1().method2().
    method3(); // Noncompliant, linebreak after '=' 

$variable_with_a_very_very_long_name 
= classInstance.method1().method2().method3(); // Noncompliant, 2nd line not indented

$a = classInstance.method1().method2().method3()
->property1; // Noncompliant, 
----


=== Compliant solution

[source,php]
----
$variable_with_a_very_very_long_name 
    = classInstance.method1().method2().method3();

$a = classInstance.method1().method2().method3()
    ->property1;
