Summary<\/strong>: in this tutorial, you’ll learn how to use the PHP ucwords()<\/code> function to make the first character of each word in a string uppercase.<\/p>\n\n\n\n

Introduction to the PHP ucwords() function #<\/a><\/h2>\n\n\n\n

The ucwords()<\/code> function accepts a string<\/a> and returns a new string with the first character of each word converted to uppercase:<\/p>\n\n\n

ucwords ( string $string , string $separators = \" \\t\\r\\n\\f\\v\"<\/span> ) : string<\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
By default, the ucwords()<\/code> function uses the following characters to separate the words in a string:<\/p>\n\n\n\n
To use different separators, you can specify them in the $separator argument.<\/p>\n\n\n\n
Note that the ucwords()<\/code> doesn’t modify the original string but returns a new modified string.<\/p>\n\n\n\n
PHP ucwords() function examples #<\/a><\/h2>\n\n\n\n
Let’s take some examples of using the ucwords()<\/code> function.<\/p>\n\n\n\n
1) Simple PHP ucwords() function example #<\/a><\/h3>\n\n\n\n
The following example uses the ucwords()<\/code> function to convert the first characters of the first name and last name to uppercase:<\/p>\n\n\n
<?php<\/span>\n\n$name = 'john doe'<\/span>;\n\necho<\/span> ucwords($name);<\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
Output:<\/p>\n\n\n
John Doe<\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
2) Using PHP ucwords() function with the strtolower() function example #<\/a><\/h3>\n\n\n\n
The ucwords()<\/code> converts the first character of each word only. It doesn’t change other characters.<\/p>\n\n\n\n
Therefore, you need to use th ucwords()<\/code> with the strtolower()<\/a><\/code> function to convert the strings. For example:<\/p>\n\n\n
<?php<\/span>\n\n$name = 'JANE DOE'<\/span>;\n\necho<\/span> ucwords(strtolower($name)); <\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
Output:<\/p>\n\n\n
Jane Doe<\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
In this example, the $name<\/code> is in uppercase. The strtolower()<\/code> function returns the lowercase version of the string. And the ucwords()<\/code> returns a new string with the first character of each word converted to uppercase.<\/p>\n\n\n\n
3) Using PHP ucwords() function with additional word delimiters #<\/a><\/h3>\n\n\n\n
Suppose you have the following name:<\/p>\n\n\n
$name = \"alice o'reilly\"<\/span>;<\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
And you want to convert it to:<\/p>\n\n\n
Alice O'Reilly<\/span><\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
If you use the default delimiters, it won’t work as expected. for example:<\/p>\n\n\n
<?php<\/span>\n\n$name = \"alice o'reilly\"<\/span>;\necho<\/span> ucwords($name);<\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
Output:<\/p>\n\n\n
Alice O'reilly<\/span><\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
To make it works, you need to add the character '<\/code> to the default separators like this:<\/p>\n\n\n
<?php<\/span>\n\n$name = \"alice o'reilly\"<\/span>;\necho<\/span> ucwords($name, \" \\t\\r\\n\\f\\v'\"<\/span>);<\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
Output:<\/p>\n\n\n
Alice O'Reilly<\/span><\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
Note that the default delimiters \" \\t\\r\\n\\f\\v\"<\/code> ensure the current logic for separating words are the same as before.<\/p>\n\n\n\n
Summary #<\/a><\/h2>\n\n\n\n
  • Use the PHP ucwords()<\/code> to returns a new string with the first character of each word converted to uppercase.<\/li><\/ul>\n
