Easy, Fast, and Efficient.
Just make sure your code is developed within a standard and you comment very well.
In some situations we are required to take a value that was intended to be a string and convert it to a numerical value for calculations.
In this situation we would implement a form of variable control called "Casting".
CODE:
-
//String
-
var string = "5.00";
-
-
//What would happen if we wanted to add another 5.00 to string?
-
//Well, it would append the 5.00 to the original 5.00 - Example: 5.005.00
-
//We need to Cast "string" so that we can do numerical calculations.
-
var numeric = parseFloat(string)+5.00;
-
//You can use
-
//parseFloat - number with a decimal point.
-
//parseInt - whole number.
Simple and effective.
How do you show errors for a single php script when the entire server has the enviorment variable "display_errors" set to 0?
Simple - place the below code at the top of your script.
CODE:
-
ini_set("display_errors", 1);
-
error_reporting(E_ALL);
ini_set - allows you to mess with your php.ini file.
error_reporting - sets what kind of errors you wish to show.
