How Can I Efficiently Capitalize Strings in PHP?

Capitalizing and Lowercasing Words for Proper Case

In the programming world, improper capitalization can pose a challenge. Consider the following string:

$str = "tHis iS a StRinG thAt NeEds ProPer CapiTilization";

To convert this string to proper case, one approach is to use ucfirst() to capitalize the first letter and then use ucwords() to capitalize each word. However, this can be a lengthy process.

Instead, consider a more concise method:

Combining strtolower() and ucwords()

The strtolower() function can be used to convert a string to lowercase, while ucwords() capitalizes the first letter of each word. By combining these functions, we can achieve the desired result with a single step:

ucwords(strtolower($str));

This line of code will first convert $str to lowercase using strtolower(). The resulting string will then be processed by ucwords(), which will capitalize the first letter of each word. The final output will be a string with proper case, as shown below:

Hello World!

This solution provides a more efficient and elegant way to handle capitalization and lowercasing in strings.
