 - `sitePassByRefFunctions` (string, default `null`): a list of custom functions which pass in variables to be initialized by reference (eg `preg_match()`) and therefore should not require those variables to be defined ahead of time. The list is space separated and each entry is of the form `functionName:1,2`. The function name comes first followed by a colon and a comma-separated list of argument numbers (starting from 1) which should be considered variable definitions. The special value `...` in the arguments list will cause all arguments after the last number to be considered variable definitions.
 - `allowWordPressPassByRefFunctions` (bool, default `false`): if set to true, a list of common WordPress pass-by-reference functions will be added to the list of PHP ones so that passing undefined variables to these functions (to be initialized by reference) will be allowed.
