I'm trying to echo only the integer from this script.

<?php
$hour = '<script type="text/javascript">
var x = new Date().getHours();
document.write(x)
</script>';

var_dump($hour);

my output from this is

string(93) "17"

but I just want to get my output as 17 as an integer.

When I try using parseInt it outputs 0.

How can I get it to output 17 instead of 0?

`var_dump((int)$hour);` – AbraCadaver Mar 16 '21 at 16:54
@AbraCadaver, I already tried that, it still sent out ```0``` – Jude Joshua Mar 16 '21 at 16:59

Why not use `\DateTime()`? Example: `$date = new \DateTime(); var_dump($date->format('H'));` – hppycoder Mar 16 '21 at 16:59

`string(93) "17"` there is more to this than meet the eye! 93 chars means you are vardumping the whole string from ` – RiggsFolly Mar 16 '21 at 17:00
Ha @RiggsFolly yes I read too fast and missed that. – AbraCadaver Mar 16 '21 at 17:00
@AbraCadaver No need to apologise to me my friend – RiggsFolly Mar 16 '21 at 17:01

So you can't just assign JS to a string and have it execute and store the result in that string. It doesn't work that way. – AbraCadaver Mar 16 '21 at 17:01
You need to learn about the [difference between client and server side](https://stackoverflow.com/questions/13840429/what-is-the-difference-between-client-side-and-server-side-programming). Also, there is no need to use JS here. The current hour can be fetched with PHP. – El_Vanja Mar 16 '21 at 17:02
@hppycoder, I want to get the user time in real-time and not make use of server time – Jude Joshua Mar 16 '21 at 17:02
If you want time from the client, then you will need to employ AJAX to pass that value to PHP. – El_Vanja Mar 16 '21 at 17:03
Then you have to write a page in HTML with some JS in it, then send the date back to the PHP using AJAX – RiggsFolly Mar 16 '21 at 17:03
Then PHP needs to be told what the browser time is. Passed through an AJAX call or some other way like a form. The server will only ever know what the server time is. It cannot possibly know what the browser is because that's on the client side – hppycoder Mar 16 '21 at 17:03

@RiggsFolly Isn't that the point of a choir, though? :) – El_Vanja Mar 16 '21 at 17:04
I bet we would all be good friends in real life – hppycoder Mar 16 '21 at 17:04
Wouldnt want to meet @El_Vanja in a dark alley judging by his picture :) :) – RiggsFolly Mar 16 '21 at 17:06
Okay guys, let me try this. Thanks for the melody. I hope it puts my code to sleep. :) – Jude Joshua Mar 16 '21 at 17:07
You got this @UbyjudeJosh. This is a good concept to learn because it affects more than just PHP and will set you up for nearly all other future endeavors as well – hppycoder Mar 16 '21 at 17:09
I would love to know how you managed to claim that var_dump produced `string(93) "17"` thats a bit of magic – RiggsFolly Mar 16 '21 at 17:10
Thanks, @hppycoder! – Jude Joshua Mar 16 '21 at 17:21
@RiggsFolly, I used an online debugger to run my PHP code when it stopped displaying on local – Jude Joshua Mar 16 '21 at 17:22
Try VCCode and XDEBUG, work like a dream – RiggsFolly Mar 16 '21 at 19:45
