want allman code formatting on php code in dreamweaver 2020

Limited PHP code formatting options are in this file on windows (make a backup of the file first):

C:\Program Files\Adobe\Adobe Dreamweaver Next\www\extensions\default\BracketsDWBeautify\default.jsbeautifyrc - at the bottom PHP otions for format source code look something like this :

"php": {
"eol": "\n",
"preserve_newlines": true,
"max_preserve_newlines": 3,
"space_after_anon_function": true,
"brace_style": "collapse",
"keep_array_indentation": false,
"keep_function_indentation": false,
"space_before_conditional": true,
"break_chained_methods": false,
"eval_code": false,
"unescape_strings": false,
"wrap_line_length": 0,
"wrap_attributes": "auto",
"end_with_newline": false,
"comma_first": false,
"space_in_paren":true
}

Alternatively you can put a .jsbeautifyrc file in the root of your current project
