To match the SQL part I think you will need two different rules (one  
for each construct).

I have written an example of matching the first construct below, let  
me know if you have further questions.

    {  begin = '(\$sql) = '; end = ';';

       # assign a scope name to the “$sql” part
       captures = { 1 = { name = 'variable.other.php'; } };

       patterns = ( # start a new context for … in “$sql = …;”

          # match strings in this context
          {  name = 'string.quoted.double.php';
             begin = '"'; end = '"';
             patterns = (
                {  match = '\\.'; }.          # escaped characters
                {  include = 'source.sql'; }  # treat content of  
string as SQL
             );
          }.

          # for that which is not matched as a string in this
          # context use the normal (root level) PHP rules
          {  include = '$self'; }
       );
    }
