How to convert first character of all the words uppercase using PHP ?

To convert the first character of all the words present in a string to uppercase, we just need to use one PHP function i.e. ucwords().

ucwords(string,delimiters): This function takes 2 parameters. The first one is the string which is mandatory. The second parameter is the delimiter. 

Example 1:

PHP

<?php
  echo ucwords("welcome to geeks for geeks");
?>

Output

Welcome To Geeks For Geeks

 The second parameter(delimiter) is optional. If we don’t mention it, then it will capitalize all the words after space. The echo keyword is used to print the output on the screen.

Example 2:

PHP

<?php
    // code
  echo ucwords("hey!let's get started","!")
?>

Output

Hey!Let's get started

As “!” is the delimiter, it will only capitalize the first letter of the word before and after “!”.

Example 3:

PHP

<?php
    // code
  $str = 'php is fun learning';
  $str = ucwords($str);
  echo $str
?>

Output

Php Is Fun Learning

For storing a string in a variable we need to put $ sign in front of the variable.
