This check looks for method names that are not written in camelCase.
In camelCase names are written without any punctuation, the start of each new
word being marked by a capital letter. Thus the name
database connection seeker becomes databaseConnectionSeeker.
The string literal publishers.title 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: SingleisValue
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.
You can fix this by adding a namespace to your class:
When choosing a vendor namespace, try to pick something that is not too generic to avoid conflicts with other libraries.
