PHP Regex special characters to include quotations

I have this JavaScript code which allows me to detect if a string contains any special characters including single and double quotations...

if (/[!@#$%^&*()_+\-=\[\]{};':"\\|,.<>\/?`~]/.test(string) === false) {
    //...
}

However when I try to do this in PHP the regex is invalid since PHP regexes have to be in quotations.

if (!preg_match('/[!@#$%^&*()_+\-=\[\]{};':"\\|,.<>\/?`~]/', $string)) {
    //...
}

How would I use this JavaScript regex in PHP? I cannot figure out a way to have a special character regex that includes quotations.
