I am using PHP for my first scripting language and am just becoming somewhat familiar with it. I would like to be able to maneuver between uppercase and lowercase at will with PHP. Can you please let me know how?

Hi,
To use PHP to convert all letters in a string to uppercase you use the following:

$string = strtoupper($string);

To convert a string to lowercase you use the following PHP code:

$string = strtolower($string);

Now if you are looking to make the first character in a string uppercase:

$string = ucfirst($string);

And if you want to make the first character in each word of the string uppercase:

$string = ucwords($string);
