Actually, you should not mix JS and PHP at all. If you need data on a page, fetch it with AJAX, or include it in a script tag with an appropriate type attribute.Teemu– Teemu2021年01月15日 09:41:02 +00:00Commented Jan 15, 2021 at 9:41

Maybe a hidden field where the value is the php variable and then you may retrieve the field value with javascriptcwhisperer– cwhisperer2021年01月15日 09:48:03 +00:00Commented Jan 15, 2021 at 9:48

@Rory McCrossan How can I attach data to HTML in the smartest way, because in my opinion I have to do it also with echo, because HTML does not know the PHP variables.Christian Teubner– Christian Teubner2021年01月15日 09:49:45 +00:00Commented Jan 15, 2021 at 9:49

1@Teemu I agree with you completely. I removed my comments as they could be misconstrued.Rory McCrossan– Rory McCrossan2021年01月15日 09:56:13 +00:00Commented Jan 15, 2021 at 9:56

1@RoryMcCrossan Though manipulating JS with PHP is a very commonly used practice (💩 is delicious, millions of flies can't be wrong, can they?), I've started to advice against it. You can imagine a fresh developer failing their first security audit, and then them explaining "But I got the code from SO ..." The dev won't feel very comfortable, and it's also bad promotion to SO too. I know I've already lost the war, but still continuing the battle, maybe we needed a canonical answer to this question, and use it like this dup target ..?Teemu– Teemu2021年01月15日 13:18:48 +00:00Commented Jan 15, 2021 at 13:18
