php-regexHow to match a space using PHP regex?

To match a space using PHP regex, you can use the \s character class. This character class matches any whitespace character, including spaces, tabs, and line breaks.

Example code

$string = 'This is a string with a space.';
$pattern = '/\s/';

if (preg_match($pattern, $string)) {
    echo 'A space was found!';
}

Output example

A space was found!
