		0 ignored issues – show Coding Style Naming introduced 2017-12-23 05:55 UTC by Report Bug Copy Issue Report The parameter $DOMDocument is not named in camelCase. This check marks parameter names that have not been 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 string becomes `databaseConnectionString`. Loading history...

		0 ignored issues – show Security Best Practice introduced 2017-12-23 05:55 UTC by Report Bug Copy Issue Report It seems like you do not handle an error condition here. This can introduce security issues, and is generally not recommended. If you suppress an error, we recommend checking for the error condition explicitly: // For example instead of @mkdir($dir); // Better use if (@mkdir($dir) === false) { throw new \RuntimeException('The directory '.$dir.' could not be created.'); } Loading history...

Our type inference engine in quite powerful, but sometimes the code does not provide enough clues to go by. In these cases we request you to add a `@return` annotation as described here.

		0 ignored issues – show Coding Style Comprehensibility introduced 2017-12-23 05:55 UTC by Report Bug Copy Issue Report The string literal `<body>` 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. Loading history...
