The following code is correct:

$str = "INSERT INTO table ('".$val1."',"."'".$val2."'".","."'".$val3."'".","."'".$val4."')";

but the code below is incorrect:

$str = "INSERT INTO table ('".$val1."',"."'".$val2."'".","."".$val3."'".","."'".$val4."')";

I want to have variables having single inverted commas on bother sides and I want the string to be made using double inverted commas.

There must be a better way.. I write a lot of queries from PHP that talk to an Oracle DB and I am constantly making mistakes with these strings!!
