Coding Style Compatibility introduced by
For compatibility and reusability of your code, PSR1 recommends that a file should introduce either new symbols (like classes, functions, etc.) or have side-effects (like outputting something, or including other files), but not both at the same time. The first symbol is defined on line 11 and the first side effect is on line 9.

The PSR-1: Basic Coding Standard recommends that a file should either introduce new symbols, that is classes, functions, constants or similar, or have side effects. Side effects are anything that executes logic, like for example printing output, changing ini settings or writing to a file.

The idea behind this recommendation is that merely auto-loading a class should not change the state of an application. It also promotes a cleaner style of programming and makes your code less prone to errors, because the logic is not spread out all over the place.

To learn more about the PSR-1, please see the PHP-FIG site on the PSR-1.

Coding Style Compatibility introduced by
PSR1 recommends that each class must be in a namespace of at least one level to avoid collisions.

You can fix this by adding a namespace to your class:

namespace YourVendor;

class YourClass { }

When choosing a vendor namespace, try to pick something that is not too generic to avoid conflicts with other libraries.

Compatibility Best Practice introduced by
Use of global functionality is not recommended; it makes your code harder to test, and less reusable.

Instead of relying on global state, we recommend one of these alternatives:

1. Pass all data via parameters

function myFunction($a, $b) {
    // Do something
}

2. Create a class that maintains your state

class MyClass {
    private $a;
    private $b;

    public function __construct($a, $b) {
        $this->a = $a;
        $this->b = $b;
    }

    public function myFunction() {
        // Do something
    }
}

Coding Style Comprehensibility introduced by
The string literal OpenSearchDescription 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.

Duplicated code is one of the most pungent code smells. If you need to duplicate the same code in three or more different places, we strongly encourage you to look into extracting the code into a single class or operation.

The string literal %7D 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.

Compatibility Best Practice introduced by
Use of global functionality is not recommended; it makes your code harder to test, and less reusable.

Instead of relying on global state, we recommend one of these alternatives:

1. Pass all data via parameters

function myFunction($a, $b) {
    // Do something
}

2. Create a class that maintains your state

class MyClass {
    private $a;
    private $b;

    public function __construct($a, $b) {
        $this->a = $a;
        $this->b = $b;
    }

    public function myFunction() {
        // Do something
    }

The string literal icon 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

$doubleQuoted = "\tSingle is $singleQuoted";

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.

The string literal 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.

The string literal author 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.

Compatibility Best Practice introduced by
Use of global functionality is not recommended; it makes your code harder to test, and less reusable.

Instead of relying on global state, we recommend one of these alternatives:

1. Pass all data via parameters

function myFunction($a, $b) {
    // Do something
}

2. Create a class that maintains your state

class MyClass {
    private $a;
    private $b;

    public function __construct($a, $b) {
        $this->a = $a;
        $this->b = $b;
    }

    public function myFunction() {
        // Do something
    }
