    timestamp showing hour which is not there

    in PHP Coding Help

    Posted

    Hello,

     

    I am comparing these 2 time stamps to see how much time has passed. They time passed is 66 seconds.

     

    When I format them back into h:m:s, it shows 1 hour, 1 minute and 6 seconds instead of just 1 minute and 6 seconds.

     

    I was just wondering why this was?

     

    Thanks

    $startStamp = 1487156507;
$endStamp = 1487156573;
$howLong = $endStamp - $startStamp;
echo $howLong . "<br>";
echo(date("h:m:s",$howLong)) . "<br>";

    A little help with the math for level/exp code

    in PHP Coding Help

    Posted

    Hi guys. I'm using php to make a basic level up experience system.

    At the moment I'm using the following math.

     



    
$level = 1; //increments on level up 
    
$constantValue = 150; 

    
$level * $constantValue = $exp2level;

     

    Ideally I would like it to be a little more complicated so the exp needed to level isn't so predictable. Now, me and maths have never got along so I'm struggling.

     

    Is there a way I can generate exp results a little like FF7. Like this:

    Thanks for any tips  :happy-04:

    can I use this code twice on one page?

    in PHP Coding Help

    Posted

    I have a div on my site that is hidden on desktop then comes visable on mobile devices. Ideally I want to use the following code to include my content in both my normal content div, and my mobile div, and just have one showing at a time.

    If I try to use it twice in my index.php page, the include default works but when I try to access a page it halts any content from loading.

    Is there a way I can use this code twice in one page?

     <?php

    if (isset($_GET['nav'])) 
{
    if (strpos($_GET['nav'], "/")) 
{
    $direc = substr(str_replace('..', '', $_GET['nav']), 0, strpos($_GET['nav'], "/")) . "/";
    $file = substr(strrchr($_GET['nav'], "/"), 1);
    if (file_exists($direc.$file.".php")) 
{
    include($direc.$file.".php");
} else {
    include("error.php");
}
} else {
    if (file_exists(basename($_GET['nav']).".php")) 
{
    include(basename($_GET['nav']).".php");
} else {
    include("error.php");
}
}
} else {
    include("default.php");
}
?>

    Thanks

    php timer

    in PHP Coding Help

    Posted

    I switched to time() and it all worked well, thanks :)

     

    I plan to change it from sessions to a database, I just used sessions when testing it on my laptop.

     

    I don't know why I thought I couldn't use that in the first place :P

     

    Is there a way to make time() a little easier to read ?

    php timer

    I am trying to make a php timer of sorts. For a city building game web app.

     

    I am using this code as a sort of time stamp but its very unreliable and jumpy.

     

    When a player clicks on a building to build, it stores the following as a session variable:

    $startTime = number_format($Time, 0, '.', '');

    the to get the current time:

    $Time = date("his");

    then to see if the 30 second build time has passed I use:

    if (isset($_SESSION['buildStart']) && ($Time - $_SESSION['buildStart'] > 30)) {
        built();
    }

    the rest of the code works fine, but sometimes the timer will jump from say 5 seconds to 25 seconds in an instant. 

     

    Does anyone have a more reliable way to check if the 30 seconds has passed?

     

    Sorry if this is all crappy code, I am tryng to make this to get better :P

     

    Edit: Oh, I don't think I can use time() because I am using the times to also make a progress bar:

    Hey guys,

     

    I am using this code to use javascript to send the browser window width to a php session variable.

    session_start();

$parentDir = basename(dirname($_SERVER['PHP_SELF']));;

if (!isset($_SESSION['screenWidth'])) {
    echo '<script>window.location = "' . "/" . $parentDir . "/" . '?width="+window.innerWidth</script>';
    if (isset($_REQUEST['width'])) {
        $_SESSION['screenWidth'] = $_REQUEST['width'];
        header("Location: " . "http://" . $_SERVER['HTTP_HOST'] . "/" . $parentDir);
    }
}

    it works fine on my pc, however, when I try it on my phone it returns a width value of 900, which is wrong.

     

    If i add the javascript directly it returns a true value of 350.

    <button onclick="myFunction()">Get Width</button>
<script>
function myFunction() {
    alert(window.innerWidth);
}
</script>

    I know this isn't just php but I was hoping someone would have any idea as to whats going on? Thanks for any help

     

    EDIT: I uploaded a demo: http://www.myprimaryweb.co.uk/checkWidth/

    shorthand syntax help

    in PHP Coding Help

    Posted

    Hey,

     

    I have only recently learnt about using shorthand. I have managed to convert most of my simple if else's and isset checks to shorthand but am struggeling with a few.

     

    Could someone show me how I would change this to shorthand, when it has two variables in the else.

    if (isset($_SESSION['posY'])) {
    $posY = $_SESSION["posY"];
} else {
    $posY = 50;
     $_SESSION["posY"] = 50;
}

    Thanks

     

    how would i use this variable?

    Hey guys,

     

    I have this variable which i use to detect touchscreens and if i need to use touchstart or click.

    var whatenemyTouch = isMobile ? 'touchstart' : 'click';

    I am trying to use it with this:

    window.onclick=function(e){

    I would like to use it inplace of onclick but I cant get it working, any ideas?

     

    Thanks

    finding difference between current date and future date.

    in PHP Coding Help

    Posted · Edited by cloudll

    Use the datetime object, and this is pretty simple.

     

     

    $date1 = new DateTime();
$date2 = date_create("2013-12-12");
$diff = date_diff($date1,$date2, true);
echo $diff->format("%R%a days");

     

    This works well to work out the difference :) Thanks. However I cant seem to echo $date1. Is this normal with datetime?

     

    EDIT: Figured it out, my silly mistake

    finding difference between current date and future date.

    in PHP Coding Help

    Hey,

     

    I have been trying to tweak this code to tell me the days between the current date and a future date. The snippet below however sets a start date rather than using the current date.

    I have been trying to format date() in a way that will work but have had no luck.

    $date1=date_create("2013-03-15");
$date2=date_create("2013-12-12");
$diff=date_diff($date1,$date2);
echo $diff->format("%R%a days");

    Could someone tell me what I need to do to get it working please? Thank you.

    I dont know much, but shouldn't that work?

    adding an }else{ to a nested if statement

    in PHP Coding Help

    Posted

    Hey people. Firstly, sorry if my Topic Title is incorrect. I wasn't 100% sure how to word it.

     

    In my code below, I have an if statement within an if statement.

     

    I have an }else{ set for one of the ifs, but I would like an }else{ for the other one. I just cannot get it working. I have tried placing it everywhere I can think of.

     

    Is it possible to have an else for this line

    if (($attackverify == "yes") && ($status == "online"))

    Here is my code.

    <?php

// HANDLE THE ATTACK

if (($attackverify == "yes") && ($status == "online"))
	{
	if (!isset($_SESSION['LAST_ATTACK']))
		{
		echo 'you attacked' . $decodedData;

		// ATTACK SQL QUERY GOES HERE

		$_SESSION['LAST_ATTACK'] = time();

		// RELOAD THE PAGE AFTER ATTACK
		// reloadPage();

		}
	elseif (isset($_SESSION['LAST_ATTACK']) && (time() - $_SESSION['LAST_ATTACK'] > 1))
		{
		echo 'you attacked' . $decodedData;
		$_SESSION['LAST_ATTACK'] = time();

		// ATTACK SQL QUERY GOES HERE
		// RELOAD THE PAGE AFTER ATTACK
		// reloadPage();

		}
	  else
		{

		// DISPLAY ERROR MESSAGE

		echo 'too soon to attack';
		echo '<br />';

		// SET SESSION

		echo $_SESSION['LAST_ATTACK'];
		echo '<br />';

		// RELOAD THE PAGE AFTER ATTACK
		// reloadPage();

		}
	}
}

    Thanks

    Okay, this is what I came up with. It works but still lets the player attack other people by changing the information in the url bar. Is there any way to change this?

            $username = null;
	if (isset($_REQUEST['username']))
		{
		$username = $_REQUEST['username'];
		}

	$attackverify = null;
	if (isset($_REQUEST['attackverify']))
		{
		$attackverify = $_REQUEST['attackverify'];
		}

	// SESSION USERNAME

	$sesusername = $_SESSION['auth'];

	// FIND ONLINE PLAYERS

	$sql = "SELECT * FROM login WHERE online='online'";
	foreach($connect->query($sql) as $row)
		{
		$un = $row['username'];

		// CANNOT ATTACK YOURSELF

		if ($sesusername == $un)
			{
			echo <<<CODE

// THIS CODE HAS NO ATTACK LINK

<img style="position:absolute; top:{$row['pos_y']}px; left:{$row['pos_x']}px;" src="engine/img/{$row['username']}.gif">
<span style="left:{$nameposx}px;top:{$nameposy}px;color:#fff;position:absolute;">{$row['username']}</span>

CODE;
			}
		  else
			{

			// ATTACK THE ENEMY

			echo <<<CODE

// THIS CODE DOES HAVE AN ATTACK LINK

<a href="?attackverify=yes&username={$row['username']}">
<img style="position:absolute; top:{$row['pos_y']}px; left:{$row['pos_x']}px;" src="engine/img/{$row['username']}.gif">
</a>
<span style="left:{$nameposx}px;top:{$nameposy}px;color:#fff;position:absolute;">{$row['username']}</span>

CODE;
			}
		}

	// HANDLE THE ATTACK

	if ($attackverify == "yes")
		{
		echo 'you attacked' . $username;

		// ATTACK SQL QUERY GOES HERE
		// RELOAD THE PAGE AFTER ATTACK

		reloadPage();
		}
	}

    linking arrays

    in PHP Coding Help

    Posted

    I was wondering if there is a way to link two arrays together. I currently have

    $enemyNames = array("The Pain", "The Fear", "The End");
    $enemyImage = array("img01", "img02", "img03");

    I am then using array_rand to generate a random "enemy"

    $enemyName = $enemyNames[array_rand($enemyNames)];

    I would ideally like to have the first enemy name linked with img01, and the second linked to img02 etc. I am not sure how I would link them together while still using array_rand. Is it possible?

    How would I go about doing this ?

    Hello,

    I am working on a little multiplayer game. When a person logs in, a session is created storing their username and their character is set to "online" in the database. I then query my database and use for each to display all the characters who are set to "online" on the game map.

     

    I'm not sure how I would go about letting the players attack each other. The attack can be used by just clicking on the other character, but I'm not sure how I would update the health in the database for the character who was attacked. does anyone have any ideas?

     

    Sorry if this question is a bit vague, I'm confused myself.

     

    Thanks for any tips.

    quick question about password hashing cost

    in PHP Coding Help

    Posted

    Hey guys, this is probably a silly question but just wanted to check.

     

    This is from the PHP manual for password_needs_rehash

        if (password_needs_rehash($hash, PASSWORD_DEFAULT, $options)) {
        
        $newHash = password_hash($password, PASSWORD_DEFAULT, $options);

    $options being the cost. I understand why the cost is being used for $newhash, but why is it being used for:

      if (password_needs_rehash($hash, PASSWORD_DEFAULT, $options)) {

    Is that actually doing anything?
