Making the string all capital letters:
You can simulate the CAPSLOCK key using thestrtoupper() PHP function.
Making the string all lower case letters:
You can also force all letters in a string to be lower case. This is done with the strtolower() PHP function.
Capitalizing each word:
You can choose to only capitalize the first letter of every word. This works great when working with a list of names or cities. This is done with theucwords() PHP function.
Code :
<?php
// using strtoupper() we can easily get all characters in capital.
echo strtoupper(“This is Premal Katigar”);
?>
<br>
<?php
// using strtoupper() we can easily get all characters in capital.
echo strtolower(“This is Premal Katigar”);
// using ucwords() we can easily get all words with first character capitalized
?>
<br>
<?php
print((ucwords(‘premal,katigar’)));
?>
