With the backslash PHP does not check the current namespace and therefore execution is faster. Install ------- [](#install) Install it with `composer require --dev soderlind/coding-standard` Use --- [](#use) Create a `phpcs.xml.dist` in the project root folder. Something like this: ``` /vendor/* Checks if global PHP functions are fully qualified. ``` If you set `onlyOptimizedFunctions` to true, backslash will only be added to [optimized functions](https://github.com/soderlind/coding-standard/blob/master/FullyQualifiedGlobalFunctions/Sniffs/FullyQualifiedGlobalFunctionsSniff.php#L21-L61).
