Example, use === or !== to determine whether a string exists.

Code:

  3. if(stripos($sql, "insert") === 0){
  4. $excuteResult = mysql_query($sql);
  5. if($excuteResult){
  6. $sql = $ sql2."where id = (select max(id) from subway2)";
  7. }
  8. } else if(stripos($sql, "delete") === 0 || stripos($sql, "update") == = 0){
  10. if (strpos($foo, “my”)===0) { echo('I find!');}
Copy code
