Right now, we will realize, how we can change over a string to capitalize? To change over the string to capitalized, we use strtoupper() strategy which returns capitalized changed over the string.
PHP – strtoupper()
This strategy takes a string regardless of contention and returns capitalized string.
Example
<?php
$str = 'hello friends';
echo strtoupper($str)
?>
Output:
HELLO FRIENDS
Different functions:
PHP – ucfirst ()
This function changes over the first letter in capitalized of the string.
Example
<?php
echo ucfirst("hello friend");
//output: Hello friends
?>
PHP – ucwords ()
This function changes over every first character of all words in capitalized.
Example
<?php
echo ucwords("how are you");
//Output: How Are You?
?>
