How to make the first letter of each word Upper Case using PHP?

Question

Answer 1

You will have to use ucfirst and loop through every word, checking e.g. an array of exceptions for each one.

Something like the following:

$exclude = array('and', 'not');
$words = explode(' ', $string);
foreach($words as $key => $word) {
    if(in_array($word, $exclude)) {
        continue;
    }
    $words[$key] = ucfirst($word);
}
$newString = implode(' ', $words);

Answer 2

This is a very useful function for titles and headings on pages, particularly if they may have been entered by the user and you want to sanitize what they entered so that your pages are nice and uniform.

It's a very simple function to use, as you can see here:

<?php $mystring = "i think this is a great page title"; echo ucwords($mystring); ?>
OUTPUT: I Think This Is A Great Page Title
