某些字符后如何大写字母？ [关闭]

Question

How can I modify a string in the following ways?

• first character uppercase
• first character after the hyphen uppercase
• first character after the slash uppercase

Here are some examples:

$a = 'foo-bar';
echo $a; // FooBar
$a = 'my-class-name';
echo $a; // MyClassName
$a = 'my-directory/my-class-name';
echo $a; // MyDirectory/MyClassName
$a = 'my-directory/my/sub/directory/my-class-name';
echo $a; // MyDirectory/My/Sub/Directory/MyClassName

Answer 1

For something like this you can use ucwords() and str_replace() e.g.

echo str_replace('-', '', ucwords($a, '-\/'));

The '-\/' basically means it will treat - and / as delimiters so it knows what to class as a new word.

Hope this helps!
