The **`ucwords()` method** in PHP makes the initial character of every word in a string uppercase.

The following figure shows a visual representation of the `ucwords()` function.

#      
#  Syntax

---
```php
ucwords(str, sep)
#  where str stands for string and sep stands for separator
```
---
##   
## Parameter

The `ucwords()` function requires two parameters:
- A string
- A #key# separator: This is an optional parameter. This character separates the words in a string. Its default value is " ". #key#


## 
## Return value

The `ucwords()` uppercases the `initial` character of every word in a string.

---
>- The rest of the string, i.e., other than the first character of every word, stays the same.
>- If the first character of the word is not a letter, then that word of the string remains the same.

#     
## Code

The code below shows how the `ucwords()` function works.

<?php
#string
echo("ucwords('edpresso shots'): ");
echo (ucwords('edpresso shots'));
echo("\n");
#string with number
echo("ucwords('hellO studentS of course 202'): ");
echo (ucwords('hellO studentS of course 202'));
echo("\n");
#string with number along with separator
echo("ucwords('dev,tech,non-tech',','): ");
echo (ucwords('dev,tech,non-tech',','));
?>
