The rule of thumb I follow with these and other Associative Arrays is: when setting the variable its $_POST['foo'] when accessing the variable its $_POST[foo]

May i rephrase that to: "Use quotes whenever possible, with one exception: within double quotes." Reason: your rule of thumb fails with: $val=$_POST['val']; Plus: when using CONSTANTs as keys, do not try to access them within quoted strings.

so it your example it would be: $sql = "select * from db where apple = '$_POST[foo]'";
