preg-match

问题 I'm using the following regex from emailregex.com to validate emails on my site. It's working like a charm in JS but I'm unable to get it working within PHP. /^(([^<>()[]\.,;:\s@"]+(.[^<>()[]\.,;:\s@"]+)*)|(".+"))@(([[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}])|(([a-zA-Z-0-9]+.)+[a-zA-Z]{2,}))$/ The issue from what I'm seeing is the backslashes, when adding it in quotes it keeps trying to escape it. Regex101 shows that it is working, it's just a matter of how to get it into PHP. Any help
