How to fix   Long Method    Complexity   

Long Method

Small methods make your code easier to understand, in particular if combined with a good name. Besides, if your method is small, finding a good name is usually much easier.

For example, if you find yourself adding comments to a method's body, this is usually a good sign to extract the commented part to a new method, and use the comment as a starting point when coming up with a good name for this new method.

Commonly applied refactorings include:

Coding Style introduced by
This class is not in CamelCase format.

Classes in PHP are usually named in CamelCase.

In camelCase names are written without any punctuation, the start of each new word being marked by a capital letter. The whole name starts with a capital letter as well.

Thus the name database provider becomes DatabaseProvider.

Coding Style Best Practice introduced by
It is generally a best practice to always use braces with control structures.

Adding braces to control structures avoids accidental mistakes as your code changes:

// Without braces (not recommended)
if (true)
    doSomething();

// Recommended
if (true) {
    doSomething();
}

Coding Style Comprehensibility introduced by
The string literal podlove-publisher/plugin.php does not require double quotes, as per coding-style, please use single quotes.

PHP provides two ways to mark string literals. Either with single quotes 'literal' or with double quotes "literal". The difference between these is that string literals in double quotes may contain variables with are evaluated at run-time as well as escape sequences.

String literals in single quotes on the other hand are evaluated very literally and the only two characters that needs escaping in the literal are the single quote itself (\') and the backslash (\\). Every other character is displayed as is.

Double quoted string literals may contain other variables or more complex escape sequences.

<?php

$singleQuoted = 'Value';
$doubleQuoted = "\tSingle is $singleQuoted";

print $doubleQuoted;

will print an indented: Single is Value

If your string literal does not contain variables or escape sequences, it should be defined using single quotes to make that fact clear.

For more information on PHP string literals and available escape sequences see the PHP core documentation.

This check looks for multiple assignments in successive lines of code. It will report an issue if the operators are not in a straight line.

To visualize

$a = "a";
$ab = "ab";
$abc = "abc";

will produce issues in the first and second line, while this second example

$a   = "a";
$ab  = "ab";
$abc = "abc";

Coding Style introduced by
Equals sign not aligned correctly; expected 1 space but found 2 spaces

This check looks for improperly formatted assignments.

Every assignment must have exactly one space before and one space after the equals operator.

To illustrate:

$a = "a";
$ab = "ab";
$abc = "abc";

will have no issues, while

$a   = "a";
$ab  = "ab";
$abc = "abc";

will report issues in lines 1 and 2.

strip_tags() is discouraged. Use the more comprehensive wp_strip_all_tags() instead.
