PHP - Find Next Time On List?

Basically I have recently been playing around with parsing a csv file. What I am looking to do at this point is simply take the date/timestamp (part of the csv file), which is in the following format:DD/MM HH:MM:SS.100th/s
For the sake of argument, lets say I have this in an array string called $csv[0] and the file has several lines that span the course of a couple hours. I wouldn't mind having to use explode() to breakup/remove the date or 100th/s IF that would make things a lot simpler.

So where would I start in trying to achieve this?. The result I am looking for will simply return "X Seconds". Storing this in a string variable would be a bonus, as I plan to use this to divide a separate piece of information.

Any examples or ideas would be great. Thank you.

ps:
Here is an example time from the csv file itself:
Code: [Select]
11/19 22:23:18.143

What are the differences and implications of UTC time and Zulu time?
  

<?php
function getArr(string $time):array
{
    $dateTime = new \DateTime($time);
    return [
        'time'=>$time,
        'timestamp'=> $dateTime->getTimestamp(),
        'dateTime' => $dateTime
    ];
}
$arr = getArr('2020-08-05');  
$arr_z = getArr('2020-08-05T00:00:00Z');  

print_r($arr);
print_r($arr_z);

echo('equal timestamps: '.($arr['timestamp'] === $arr['timestamp']?'true':'false'));

 

Array
(
    [time] => 2020-08-05
    [timestamp] => 1596585600
    [dateTime] => DateTime Object
        (
            [date] => 2020-08-05 00:00:00.000000
            [timezone_type] => 3
            [timezone] => UTC
        )

)
Array

        (
            [date] => 2020-08-05 00:00:00.000000
            [timezone_type] => 2
            [timezone] => Z

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.

OK So I've got a datepicker that sends a date in d/m/y format. My DB stores the data in Unix Timestamp Which I can convert the date to with strtotime however this does the exact date & time.

All I want is the actual day. I've spent hours trying to convert this with just the day with mixed results...

Thanks.

Hello,

I tried to implement some PHP code to enable a web page to show "Dinner" specials versus "Lunch" specials based on the time.

The business is located in the Eastern Time Zone, so I only need to routine to work based on Eastern Time (New York).

What I am noticing is that the server is processing the lines of code so fast that the command to establish the correct time for the remaining code is not always being acknowledged.

This line of code appears to be processing too fast for the remaining lines of code:
date_default_timezone_set ( "America/New_York" );

Is there some additional code I can put in place to make sure the correct time is always ascertained?

I need the $hourmin variable to always return a combination of hour + minute based on 24-hour time and Eastern Time zone.

My code is as follows:


 <?php
   $name8 = file_get_contents("test/special8name.txt");
date_default_timezone_set ( "America/New_York" );
$gethour = date("H");
$getminutes = $gettimedate["minutes"];
$gettimedate = date();
$hourmin = $gethour . $getminutes;
$currentday = date("l", time());
$currentdate = date("M j, Y");
if ($hourmin < 1500 && $currentday <> "Saturday" && $currentday <> "Sunday") {
   echo "<span class=\"namesred\">$name8 </span>";
}
  else if ( $hourmin > 1500 && $hourmin < 2300 && $currentday <> "Saturday" && $currentday <> "Sunday") {
   echo "<span class=\"namesblue\">$name8 </span>";
  }
  else if ( $currentday == "Saturday" or $currentday == "Sunday") {
   echo "<span class=\"namesblue\">$name8 </span>";
  }
?>

I am having a problem with PHP displaying the correct date and time. It updates as it should, but is fast by 4min and is always displaying a date in 2004. I ran a basic php script to make sure the application im using itself is not wrong. go to lunenburgledger.com/time.php

Anybody had any ideas on where to check? The system time on the Windows Server 2003 is correct. The only thing I can think of is that it was converted to a virtual machine on vmware esxi, but the system time stayed right. Any ideas?

Thanks!

Hi,
In my mysql database i have a text input option, in the registration form and edit my details form i have a multiple select dropdown list, which user selects options to populate the text input box, which ultimately populates the text field in the mysql database.
All works perfectly.

The dropdownlist consists of 3 parts <optgroups> first is current selection (what is the usesr current selection)works fine, The second <optgroup> is existing words, what words we(the site) have given as options, and the third <optgroup> is the words that others have used. This is where im having a small problem.
Because its a text field when i call the data from the database, it calls the entire text box as a single option in my select list..

I want to break the words in the text field (at the comma) and have them listed each one as an option in the select list.


Example what i need:

Words in text box:(my input allows the "comma")
word1, word2, word3, word4, word5, word6,

How i want them called/displayed:
<option value=\"word1\">word1</option>
<option value=\"word2\">word2</option>
<option value=\"word3\">word3</option>
<option value=\"word4\">word4</option>
<option value=\"word5\">word5</option>
<option value=\"word6\">word6</option>

here's my code:
$query = "SELECT allwords FROM #__functions_experience WHERE  profile_id  = '".(int)$profileId."' LIMIT 1";
         $original_functionsexperience =doSelectSql($query,1);
         $query = "SELECT allwords FROM #__functions_experience WHERE  profile_id  = '".(int)$profileId."' LIMIT 1";
         $functionsexperiencelist=doSelectSql($query);
          $funcexpList ="<select multiple=\"multiple\" onchange=\"setFunctionsexperience(this.options)\">";   
         foreach ($functionsexperiencelist as $functionsexperienceal)
            {
            $selected="";
            if ($functionsexperienceals->allwords == $original_functionsexperience)
               $selected=' selected="selected"';
            $allwords=$functionsexperienceal->allwords;
            $funcexpList .= "<optgroup label=\"Current selection\">
            <option value=\"".$allwords."\" ".$selected." >".$allwords."</option>
            </optgroup>      
              <optgroup label=\"Existing Words\">
              <option value=\"existing1,\">existing1</option>
              <option value=\"existing2,\">existing2</option>
              <option value=\"existing3,\">existing3</option>
              <option value=\"existing4,\">existing4</option>
              <option value=\"existing5,\">existing5</option>
              <option value=\"existing6,\">existing6</option>
         </optgroup>
         <optgroup label=\"Others added\">    //heres problem
         <option value=\"".$allwordsgeneral."\">".$allwordsgeneral."</option>
         </optgroup>";
            }
         $funcexpList.="</select>";
         $output['FUNCEXPLIST']=$funcexpList;         
      
         
   The result im getting for optgroup others added:
   word1, word2, word3, word4, word5,

how can i get it like this:
<option value=\"word1\">word1</option>
<option value=\"word2\">word2</option>
<option value=\"word3\">word3</option>
<option value=\"word4\">word4</option>
<option value=\"word5\">word5</option>
<option value=\"word6\">word6</option>

Hi , I have one question .. Can I split showing of content of dynamic list in 2 parts , when I echo list in code ..

Code: [Select]
<?php 
// Run a select query to get my letest 8 items
// Connect to the MySQL database  
include "../connect_to_mysql.php"; 
$dynamicList = "";
$sql = mysql_query("SELECT * FROM products ORDER BY date_added DESC LIMIT 8");
$productCount = mysql_num_rows($sql); // count the output amount
if ($productCount > 0) {
while($row = mysql_fetch_array($sql)){ 
             $id = $row["id"];
 $product_name = $row["product_name"];
 $price = $row["price"];
 $date_added = strftime("%b %d, %Y", strtotime($row["date_added"]));
 $dynamicList .= '<table width="100%" border="2" cellspacing="2" cellpadding="2">
        <tr>
          <td width="17%" valign="top"><a href="product.php?id=' . $id . '"><img style="border:#666 1px solid;" src="inventory_images/' . $id . '.jpg" alt="' . $product_name . '" width="77" height="102" border="2" /></a></td>
          <td width="83%" valign="top">' . $product_name . '<br />
            $' . $price . '<br />
            <a href="product.php?id=' . $id . '">View Product Details</a></td>
        </tr>
      </table>';
    }
} else {
$dynamicList = "We have no products listed in our store yet";
}
mysql_close();
?>


Code: [Select]
<p><?php echo $dynamicList; ?><br />
</p>
It works ok, and putting my files, everything works, but when I put 8 pictures with price and other details, it just show one image with details and another image below with details, and the third image below and so on ..
Can I split dynamic list to show 4 images with details on the left side and 4 on the right side?

Thank you in advance for help , if is possible

Hi, I use the following code to create a select menu from an array of options stored in LISTS.php:


include 'LISTS.php';

print('<select id="from" name="from">');
foreach ($langList as $lang) {printf('<option %s>%s</option>', 
     ($from1 == $lang ? 'selected="selected"' : ''), $lang);
     }
echo '</select>';


where LISTS.php includes the following:
$langList = array(' ','English', 'French', 'German', 'Dutch', 'Spanish');

This works great, but now I want to do something similar with a checkbox list, where each checkbox has an associated 'onchange' javascript function and I'm getting pretty stuck.

My checkbox list is of the following form:

Code: [Select]
<html>
<ul style="height: 95px; overflow: auto; width: 200px; border: 1px solid #480091; list-style-type: none; margin: 0; padding: 0;">
    <li id="li1b"><label for="chk1b"><input name="chk1b" id="chk1b" type="checkbox" onchange="function1('chk1b','li1b')">Option1</label></li>
    <li id="li2b"><label for="chk2b"><input name="chk2b" id="chk2b" type="checkbox" onchange="function1('chk2b','li2b')">Option2</label></li>
//etc.
 </ul>
</html>
What I want to do is have 'Option1', 'Option2', etc. stored in an array in LISTS.php and have a PHP script that populates the checkbox list accordingly, in a similar manner to my select menu above. I can't work out how to get the ID of the next <li> and the next <input> in the list to go up by one each time, e.g. 'li1b' then 'li2b', 'li3b', etc.

Could someone pls help me out? Thanks!

I have this:

    $sql = mysqli_query($conn, "SELECT ip
                                     , page
                                     , CASE WHEN referrer = ''
                                            THEN 'N/A'
                                            ELSE referrer
                                       END as referrer     
                                     , DATE_FORMAT(date, '%m/%d/%y') as date
                                     , TIME_FORMAT(time, '%T') as time
                                FROM tblTraffic 
                                ORDER BY date DESC, time DESC");

most of my traffic report contains the correct times, my time, which is CST in the USA.  but some records are off by a lot.  Does the time() function capture the time of the actual location from which the visitor is coming from?  if so, what could I do to return my timezone for any visitor?  w3 schools and php.net don't mention this.

I am making a time clock, and I was wondering what is the best way to calculate the number of hours an employee worked?

I have a table called "statuses" it holds names of punch types:
- id = the auto_inc
- status = "in/out/break/lunch" text statuses
- paid = whether or not the punch is paid or not (true/false)

I have another table called "logging" This table holds the information about the punch type:
- id = the auto_inc
- owner = the member id
- ip = members ip
- inout = the punch type from the statuses table
- location = the city/state of where the punch took place
- date = the time the member punched

Maybe I am over thinking this, but what is the best way to calculate the hours a person has worked?

Right now I am getting all the punches for for a particular member between a date range. then loop through the data to display it and passing it to a method in a class called Calc. I want to then add the times from punch in to punch out, then the next punch in to punch out.

Any suggestions?

Hi,

The hosting provider for my domain confirm me that the server time is in EST (UTC-5). They also sent me a grab supporting that
Code: [Select]
server time is now:
----------------------
Sun Nov 7 02:20:01 EST 2010
-------------------

But when I use the following code, the output I get is has 1 hr difference (UTC-6)
echo date("d M, Y h:i:s A",time());

Output==> 07 Nov, 2010 01:20:01 AM

But it suppose to give the same time as the server, ryt? Can anybody please explain?

Thanks,

Let's say I am buying a share for $10.

If I sell the share on the same day BEFORE 3:30PM, it will be sold for $10, but if I keep the share past 3:30PM, I want the code to automatically add $1 (Taxes and such) once in the the price of the share in database, after that no matter how many days pass by, the price will remain the same.

 

I've thought about CRON jobs, but I have no idea how to make/use them or set them up.

 

Any direction or help is appreciated.

 

 

Is there a way to take data that is listed like a,b,c,d,e and turn that into an unordered list?

Basically, I'm going to have a list of schools that will be listed with comma separators.  I'll print that data out in two places, one will be printed as it's in the database.  The other I would like to echo as an unordered list.
