php-regexHow to use PHP regex to match a hyphen?

To match a hyphen using PHP regex, you can use the - character. For example:

$string = 'This-is-a-string';

if (preg_match('/-/', $string)) {
    echo 'Match found';
}

Output example

Match found

The code above uses the preg_match() function to check if the - character is present in the string. If it is, it prints out Match found.

Code explanation

• $string = 'This-is-a-string';: This is a string containing a hyphen.
