PHP - How To Convert Normal Time To Timestamp

PHP 5.2.6

We rent PHP server space on a server in California. Several of my pages generated by PHP show the current date and time, so when the page is printed, the user knows when the data was printed. Our users could be anywhere in the US, I am in Michigan. How do I convert the server time (PDT) into local time, regardless of where the user is?

Thanks.

hey guys im wondering how you would add or takeaway a hour from a timestamp in a database when trying to select it please?   thank you

Hello

I have a timestamp formated as : "2011-10-20 12:37:21"

I need to show days left till this date (disregard the hours, minutes, seconds..), so I'll end up with 'there is "X" days left untill'

I really cannot figure you all this date/time stuff, but hopefully this is not to difficult 

Anyone got a "quick" code for this?

    

I have to two variables $cronlast and $cronnow in my php code.
I need to have the time 7am of previous day in $cronlast variable and  7am today in $cronnow variable.
I need the time in UNIX timestamp format.
So everyday when I print the variable I should have:

$cronlast=7am Yesterday(in Unix Timestamp)
$cronnow=7am Today(in Unix Timestamp)

I would appreciate any help.

How to output a MySQL timestamp field to correct local time with daylight saving with PHP?   Local time is set in php.ini with: date.timezone = "Europe/London"   Confirmed set with:   <?php echo date_default_timezone_get(); ?>   But when I echo the timestamp field it does not display correct UK time for the record (an hour behind correct UK time).   <?php echo date('jS F Y - g:ia', strtotime($row['Date'])); ?>  

I have a form that submits G

How can I convert this to string of time when I need to insert it into the database and then turn it back around when it needs to be read?

          
<option>11:00 AM</option>
<option>11:30 AM</option>
<option>12:00 PM</option>
<option>12:30 PM</option>
<option>1:00 PM</option>
<option>1:30 PM</option>


Thank you.

Is it possible to convert time(); to date();?

I have all the dates stored in my database as UTC and I want to retrieves these UTC date/time to show the local time zone. So, example, If I live in New York, I want it to show east coast time zone and not the Universal Time. Any idea?

Hello, i need a fast convertor that converts the date format 03-03-2008, 08:26 PM into a timestamp fast.
Like, you paste 03-03-2008, 08:26 PM into a post form, submit and it gives you the time stamp.

I made a convertor a whille ago, but you need to insert each numbers into a separate input box (day, months, year etc)
I cant remember how exactly it functions etc asi haventtouched PHP In a while.....

This is a string.

Hello All, 
  Need an advise in finishing this task please. 
 

function convertTimeFormat($time12Hour) {
// Initialized required variable to an empty string.
		$time24Hour = ""; 

// Used explode() function to break the string into an array and stored its value in $Split variable. 
		$Split = explode(":",$time12Hour); // print_r(explode (":", $time12Hour)); => Array ( [0] => 09 [1] => 50 [2] => 08AM )

// Retrieved only "hour" from the array and stored in $Hour variable. 
		$Hour = $Split[0];   

    $Split[2] = substr($Split[2],0,2);

// Used stripos() function to find the position of the first occurrence of a string inside another string.	
		if($Hour == '12' && strpos($time12Hour,"AM")!== FALSE) {
			// Code here 
		} elseif(strpos($time12Hour,"PM")!== FALSE && $Hour != "12") {
			// code here
		}
		return  $time24Hour;
	}
	$time12Hour = "09:50:08AM";
	$result = convertTimeFormat($time12Hour);
	print_r($result); 

/*
Input : "09:50:08AM";
Output : "21:50:08PM";
*/

 

Hey guys im fairly new to php i cant really keep using that as an excuse anyway im to the point where i am comfortable with procedural php style programming and i have moved on to object orientated and prepared statements etc. Anyways this has no relevance to that sorry.

Ok when using $_GET in php say for example i wanted to log a user out i would use ?status=logout or whatever i have started to instead use that use codes like ?abihcofscj=21904jkq i know this looks weird and there is probs no need but does any over sites use this type of behavior or am i just being retarded haha thanks

Hi All,

When I put

echo memory_get_usage();

at the very beginning of a php file I get 51207808. Is this normal while there is not much processing to do ? This happens even for very small php files that only display html syntax.

Thanks!

Hello,   Is anybody aware of a statistical function in PHP which returns the inverse of the normal cumulative distribution, given a probability, mean and standard deviation as inputs?

Thank you.
