This a PHP area of the forum. Most of that code you pasted contains HTML and SQL. If you want someone to help explain whats going on with the PHP, strip everything from the document except the PHP.

If the code is too long people probably won't reply. People have better things to do that read an encyclpedia for someone, but if the codes short then you will probably find people can explain breifly the function of the code.

 

The PHP manual is pretty good for explaining what each function does (something like if() or echo()), so if you learn what the functions do and step back and look at them working together, you will probably figure out the purpose of the document.

http://php.net/manual/en/index.php

 

If you can't understand what the page does, then you've probably ripped the script off a tutorial site. That site should have a description of the function.

      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";

    case "long":
    case "int":
      $theValue = ($theValue != "") ? intval($theValue) : "NULL";
      break;
    case "double":
      $theValue = ($theValue != "") ? "'" . doubleval($theValue) . "'" : "NULL";
      break;
    case "date":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;
    case "defined":
      $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
      break;
  }
  return $theValue;
}
}

It is hard to explain a complex section of code without anybody knowing what your skill level is, if you are VERY new to PHP then some of the items in that code will be hard to understand.

The best way to learn about each section is to look at the Manual, that is what it is there for.

Ill even get you started :)

The main part is switch()

The assignment of $theValue inside the switch is being done by the use of a ternary operator
