php-regexHow to use regex in PHP to match any character including newline?

Regex (Regular Expressions) is a powerful tool used to match patterns in strings. In PHP, it can be used to match any character including newline.

Example code

$string = "This is a string
with a newline";

$pattern = "/^.*$/m";

if (preg_match($pattern, $string)) {
    echo "Match found!";
}

Output example

Match found!

Code explanation

• $string: This is the string that we are trying to match.
• $pattern: This is the regex pattern that we are using to match the string. The /m modifier at the end of the pattern tells PHP to match the pattern across multiple lines.
• preg_match(): This is the PHP function used to match the pattern against the string.
