Importing all external classes in a file through use statements makes them clearly visible. Consider changing error_reporting() level and/or setting up your own error handler. ![]() Moreover it can slow down the execution of your code. 'non-associative 0-element', // not appliedįalse => 'associative 0-element', // appliedĮrror suppression should be avoided if possible as it doesn't just suppress the error, that you are trying to stop, but will also suppress errors that you didn't predict would ever occur. If it's known from the beginning that the key will have different value, there is usually no point in defining first one. In many cases, this is an expected behavior, but can lead to many difficult to spot bugs, especially when the right operand could result in zero, null or an empty string.ĭefining another value for the same key in an array literal overrides the previous key/value, which makes it effectively an unused code. Assignments in PHP return the right operand as their result. Example: /^create/iĪssignments in if clauses and the like are considered a code smell. This rule has the following properties: Name ![]() The only case when static access is acceptable is when used for factory methods. Avoid using static access at all costs and instead inject dependencies through the constructor. Static access causes unexchangeable dependencies to other classes and leads to hard to test code. For very simple assignments you could also use the ternary operations. To achieve this, use early return statements, though you may need to split the code in several smaller methods. You can rewrite the conditions in a way that the else clause is not necessary and the code becomes simpler to read. Example: /^(_construct|get.*Filtered)$/Īn if expression with an else branch is basically not necessary. You can fix this problem by extracting the logic in the boolean flag into its own class or method.Ĭomma-separated class name list of exceptions BooleanArgumentFlagĪ boolean flag argument is a reliable indicator for a violation of the Single Responsibility Principle (SRP). This includes rules from SOLID and object calisthenics. The Clean Code ruleset contains rules that enforce a clean code base.
