To contribute to uniform, clean, and understandable coding, WordPress has introduced coding standards forPHP tagsIf you are building WordPress projects using PHP markup, adhere to the following coding rules.
Using quotes
WordPress recommends using both double and single quotes in appropriate situations. Single quotes can be used within a string when nothing is being evaluated. When using quotes, reserve one quote style for use within a string and another for enclosing the entire string.
Escaping quotes within a string is not recommended.
indentation
When you use indentation, WordPress emphasizes using the egypt phone number list tab key instead of the spacebar to mark indented lines of code. The advantage of this is that your code becomes compatible with different editors using it on different platforms.
Indentation helps to highlight logical areas of your code, making them clear and understandable
If you are using associative arrays and they contain multiple items, each item in the array should be on its own new line. Add a comma at the end of the last item in your array. This makes it easier to add new elements to the array or change its order.
PHP tags
When using PHP code snippets in HTML blocks, the opening and closing PHP tags should be on a separate line.
WordPress prohibits the use of shortened PHP tags because they can cause problems during the execution of your code.
