Eliminating Whitespace Characters from a String

In the context of programming, handling whitespace characters efficiently is essential for data manipulation. This question explores the means of removing all whitespace characters from a string.

The initial attempt using the php_strip_whitespace function and preg_replace with a simple whitespace character as the target proved ineffective. Seeking a comprehensive solution, the question explores the use of a regular expression to tackle this issue.

The provided solution employs a regular expression to replace any consecutive whitespace characters with an empty string. This ensures that all whitespace, regardless of its extent or variation, is effectively eliminated from the target string.

For example:

$str = "   Hello World   ";
$str = preg_replace('/\s+/', '', $str);
echo $str; // Output: HelloWorld

The solution leverages the power of regular expressions to provide a flexible and efficient method for removing whitespace characters.
