How Can I Efficiently Convert a String to

Capitalize First Letter of Each Word and Correct Case for Others

The question presents a situation where some string characters are improperly capitalized. The goal is to convert the string to title case, i.e., capitalize the first letter of each word and lowercase the rest.

While using ucfirst($str) to convert the first character of the string to uppercase is common, it does not handle other characters correctly.

A more efficient approach is to use a combination of ucwords() and strtolower().

$str = "tHis iS a StRinG thAt NeEds ProPer CapiTilization";
$newStr = ucwords(strtolower($str));
echo $newStr; // Hello World!

This code first lowers all characters in the string using strtolower() and then capitalizes the first letter of each word using ucwords(). Combining these functions effectively corrects the capitalization of the entire string.
