![]() ![]() Control StructuresĬontrol structures include if, for, while, switch, etc. Put a space between the (type) and the $variable in a cast: (int) $mynumber. The operator MUST NOT be used in PHP code. Unary operators (operators that operate on only one value), such as ++, should not have a space between the operator and the variable or number they are operating on.Ĭhecks for weak-typed inequality MUST use the != operator. For example, an assignment should be formatted as $foo = $bar rather than $foo=$bar. should have a space before and after the operator, for readability. So, for example, a file header might look as follows:, etc. This includes the /** */ block, the namespace declaration and the use statements (if present) as well as the subsequent code in the file. This avoids the verbose "\ No newline at end of file" patch warning and makes patches easier to read since it's clearer what is being changed when lines are added to the end of a file.Īll blocks at the beginning of a PHP file should be separated by a blank line. Lines should have no trailing whitespace at the end.įiles should be formatted with \n as the line ending (Unix line endings), not \r\n (Windows line endings).Īll text files should end in a single newline (\n). This document is loosely based on the PEAR Coding standards. Write it in a way that works either for both or decently for both.Changes to Drupal coding standards are proposed and discussed in issues in the Coding Standards project. This way if you want your code to be decently portable between languages, if that's a concern. ![]() Which is also usable in PHP in the same way. For all other cases adapt your code accordingly. Though be pleasantly surprised is they are. So you should never expect the same behavior in any of them. Not all languages do things the same way.
