PHP：如何转义parse_ini_file / parse_ini_file_string函数的注释符号

I have ini file option:

test="hello;wordl"

If you use INI_SCANNER_RAW argument in parse_ini_file function then it returns:

[test]="hello

because (;) is a comment symbol.

I tried to use (\) escape symbol before (;) but result was the same. Do you have any idea about how to escape the comment symbol?
