How to Change a Lowercase I to Uppercase in PHP

Maintain you server file content using PHP.

PHP is a server-side scripting language that you can use to include interactivity in your Web pages. It includes built-in functions for performing simple to complex modifications on your server files, including string transformations. There may be times when you need to modify string data. Change a lowercase "I" to and uppercase "I" using the PHP "str_replace" function.

Instructions

1. Open your file processing PHP script. Scroll to the area that parses your file data.

2. Type the "str_replace" code and include the current string, desired string, and string to modify in the parameters:

   $mystring = "The data that i want to change";

   str_replace("i", "I", $mystring);

   The resulting string is "The data that I want to change."

3. Save your PHP file, and transfer it to your server.
