If time is between X and Y BUT check that it's a certain time zone

[416bc]

I'm trying to use php to display an image depending on time of day. It's for a live chat image. Here is the code I'm tweaking. I didn't write it.

function date_at_timezone($format, $locale, $timestamp=null){
  
  if(is_null($timestamp)) $timestamp = time();
  
  //Prepare to calculate the time zone offset
  $current = time();
  
  //Switch to new time zone locale
  $tz = date_default_timezone_get();
  date_default_timezone_set($locale);
  
  //Calculate the offset
  $offset = time() - $current;
  
  //Get the date in the new locale
  $output = date($format, $timestamp - $offset);
  
  //Restore the previous time zone
  date_default_timezone_set($tz);
  
  return $output;
  
}

//Examples
$t = time();

print date("g:i A T", $t); //4:16 PM PDT
print date_at_timezone("g:i A T", "America/Los_Angeles", $t); //7:16 PM EDT
print date_at_timezone("g:i A T", "Pacific/Samoa", $t); //12:16 PM SST
print date("g:i A T", $t); //4:16 PM PDT

$time = date(H);
if ($time <18 ¦¦ $time > 22) 
{ 
display_one_thing(); 
} 
else 
{ 
display_other_thing(); 
} 

Can someone help me? I'm thinking something along these lines

$time = date(H:i);
if ($time < 08:30 || $time > 17:00) 
{ 
display_one_thing(); 
} 
else 
{ 
display_other_thing(); 
} 

But how do I make that check for only the 'America/Los_Angeles' time zone?

Title should read BUT not BUY, sorry.

Found my own answer:

<?php
function date_at_timezone($format, $locale, $timestamp=null){
 
 if(is_null($timestamp)) $timestamp = time();
 
 //Prepare to calculate the time zone offset
 $current = time();
 
 //Switch to new time zone locale
 $tz = date_default_timezone_get();
 date_default_timezone_set($locale);
 
 //Calculate the offset
 $offset = time() - $current;
 
 //Get the date in the new locale
 $output = date($format, $timestamp - $offset);
 
 //Restore the previous time zone
 date_default_timezone_set($tz);
 
 return $output;
 
}

$t = time();
$time = date_at_timezone("Hi", "America/Los_Angeles", $t);
if ($time > '0830' && $time < '1700') 
{ 
echo 'Business Hours'; 
} 
else 
{ 
echo 'After Hours'; 
} 

?>

Hi there 416bc,

Welcome to WebmasterWorld!

Cool that you have figured this out; I shall only offer a little tweek here, It's not going to affect the function, but it's good practice to do something like this:-

if (($time > 0830) && ($time < 1700)){
echo 'Business Hours';
exit;
}
else{
echo 'After Hours';
exit;
}

Use parenthesis in the if clause especially if you are using logical operators [php.net ], this makes the evaluation easier to read & the exits serve a good purpose too; this stops the script executing any other code further down and just makes it tidier IMO. This is particularly advantageous if you have a header(); always good to exit after a header!

Cheers,
MRb

Thanks. I had those there at one point, but in all my testing I deleted them. Thanks for the information.
