This function works fine without using regex. So it is really faster and low resource hungry.

", ";", "'", ". ");
    $str = str_replace( $remove_chars, ' ', $str );
    $parts = explode(' ', $str);
    if(count($parts) > 0){
        foreach($parts as $part){
            $part = trim($part);
            if( $part != '' ) {
                if( filter_var($part, FILTER_VALIDATE_EMAIL) !== false){
                    $emails[] = $part;
                }                
            }
        }
    }
    if(count($emails) > 0){
        return $emails;
    }
    else{
        return null;
    }
}

$string = "Guys, please help me to extract valid sam-ple.1990@gmail.co.uk email addresses from some text content using php
example , i have below text content in mysql database ' Life is more beautiful, and i like to explore lot please email me to sample@gmail.com. Learn new things every day. 'from the above text content i want to extract email address 'sample-x@gmail.com' using php regular expressions or other method.";

$matches = extract_email_addresses( $string );
print_r($matches);
