Changing Cases
For those who aren't acquainted with PHP, changing uppercase letters to lowercase and vice versa is not easy. Thankfully, PHP is around to provide functions to do this for you. Without further delays, we'll continue with the lesson...
Step 1: Uppercase
This part will discuss how you can change all the letters to uppercase. Here's the code:
<?php
$Text = "example";
$Text = strtoupper($Text);
echo $Text;
?>
In the code above, we changed Text from example to EXAMPLE. This can be handy if you have a blog and you want the title of your entries to be all uppercase.
Step 2: Lowercase
This part will discuss how you can change all the letters to lowercase. Here's the code:
<?php
$Text = "EXAMPLE";
$Text = strtolower($Text);
echo $Text;
?>
In the code above, we changed Text from EXAMPLE to example. Good for getting rid of those ugly sTiCkY caps.
Step 3: Capitalize 1st Letter
This part will discuss how you can change the first letter of the first word to uppercase. Here's the code:
<?php
$Text = "this is an example";
$Text = ucfirst($Text);
echo $Text;
?>
In the code above, we changed Text from this is an example to This is an example. Best for one-liners.
Step 4: Capitalize 1st Letter Of Each Word
This part will discuss how you can change the first letter of each word to uppercase. Here's the code:
<?php
$Text = "this is an example";
$Text = ucwords($Text);
echo $Text;
?>
In the code above, we changed Text from this is an example to This Is An Example. Usually used for names or titles of articles.
Conclusion
I told you it was easy. Try it out for yourself and see how great PHP is.
