Splitting CamelCase Words with preg_match

Question:

How can I split a camelCase word like "oneTwoThreeFour" into individual words such as "one Two Three Four" using preg_match in PHP?

Answer:

Instead of using preg_match, you can employ the preg_split function as follows:

<code class="php">$arr = preg_split('/(?=[A-Z])/', $str);</code>

Explanation:

Preg_split() with the regular expression "/(?=[A-Z])/" splits the input string just before any uppercase letter encountered. This behavior is achieved because the regular expression matches the position just before an uppercase letter, enabling you to break down the camelCase word into its component words.
