PHP - Problems With Microtime() And Date() Functions

Hi all,

I post a strange behavior that could be reproduced (at least on apache2+php5).
I don't know if I am doing wrong but let me explain what I try to achieve.

I need to send chunks of binary data (let's say 30) and analyze the average Kbit/s at the end :

I sum each chunk output time, each chunk size, and perform my Kbit/s calculation at the end.

Code: [Select]
<?php

// build my binary chunk
$var= '';
$o=9000;
while($o--)
{
$var.= "testtest";
}

// get the size, prepare the memory.
$size = strlen($var);
$tt_sent = 0;
$tt_time = 0;

// I send my chunk 30 times
for ($i = 0; $i < 30; $i++)
{
// start time
$t = microtime(true);
echo $var."\n";
ob_flush();
flush();
$e = microtime(true);
// end time
// the difference should reprenent what it takes to the server to 
// transmit chunk to client right ?

// add this chuck bench to the total
$tt_time += round($e-$t,4);
$tt_sent += $size;
}

// total result
echo "\n total: ".(($tt_sent*8)/($tt_time)/1024)."\n";

?>

In this example above, it works so far ( on localhost, it oscillate from 7000 to 10000 Kbit/s through different tests).

Now, let's say I want to shape the transmission, because I know that the client will have enough of a chunk of data to process for a second.

I decide to use usleep(1000000), to mark a pause between chunk transmission.

Code: [Select]
<?php

// build my binary chunk
$var= '';
$o=9000;
while($o--)
{
$var.= "testtest";
}

// get the size, prepare the memory.
$size = strlen($var);
$tt_sent = 0;
$tt_time = 0;

// I send my chunk 30 times
for ($i = 0; $i < 30; $i++)
{
// start time
$t = microtime(true);
echo $var."\n";
ob_flush();
flush();
$e = microtime(true);
// end time
// the difference should reprenent what it takes to the server to 
// transmit chunk to client right ?

// add this chuck bench to the total
$tt_time += round($e-$t,4);
$tt_sent += $size;

usleep(1000000);
}

// total result
echo "\n total: ".(($tt_sent*8)/($tt_time)/1024)."\n";

?>

I am doing something wrong ? Does the buffer output is not synchronous ?

Thanks a Lot

I'm trying to switch two dates if one is before the other, but I'm getting some very strange output from this code....


I've verified that the variables contain the correct information, HOWEVER when this code is run, the returns a

$rangeStart = 2016-03-02  <- This is the return even if I give it a static date!
$rangeEnd = 2010-09-19

or blank!  What am I doing wrong?


For this example:

Code: [Select]
$selDay = 17;
$selMonth = 9;
$selYear = 2010;
$pDay[0] = 14; //Day
$pDay[1] = 9; //Month
$pDay[2] = 2010; //Year

$errMsg = "selDay: ".$selDay."-".$selMonth."-".$selYear."; pDay: ".$pDay[0]."-".$pDay[1]."-".$pDay[2]."; selRange: ".$selRange."; TEMP: ";

        if(mktime(1,1,1,$selMonth,$selDay,$selYear)>mktime(1,1,1,$pDay[1],$pDay[0],$pDay[2]))
{
$reverse = true;

$tmp = $pDay[0];
$pDay[0] = $selDay;
$selDay = $tmp;
$errMsg.="<br />selDay=".$selDay."<br />pDay[0]=".$pDay[0];


$tmp = $pDay[1];
$pDay[1] = $selMonth;
$selDay = $tmp;
$errMsg.="<br />selMonth=".$selMonth."<br />pDay[1]=".$pDay[1];

$tmp = $pDay[2];
$pDay[2] = $selYear;
$selDay = $tmp;
$errMsg.="<br />selYear=".$selYear."<br />pDay[2]=".$pDay[2];
}
$RangeStart = date("Y-m-d",mktime(1,1,1,$selMonth,$selDay,$selYear)); //Selected Range start in d-m-Y
$RangeEnd = date("Y-m-d",mktime(1,1,1,$pDay[1],$pDay[0],$pDay[2])); //Selected Range start in d-m-Y
$errMsg.=";<br /> Range Start: ".$pRangeStart."; <br />Range End: ".$pRangeEnd.";

echo $errMsg;

Returns:

Code: [Select]
selDay: 17-9-2010;
pDay: 14-9-2010;
selRange: ;
TEMP:
selDay=14
pDay[0]=17
selMonth=9
pDay[1]=9
selYear=2010
pDay[2]=2010;
Range Start: ;
Range End: ;

This is getting annoying.  Any help would be wonderful.

hi there.

can someone tell me how to get this to print out the real minutes instead of the month?

echo date("M-d-Y H:m:s", mktime());

i've read http://www.sqlite.org/lang_datefunc.html but i can't seem to get it to work.

I have a script I am putting together that simulate a cricket game. The only issue is, that there are a huge number of functions because there doesn't seem to be any other way to do this properly. As well as this, there a while() loop and all this seems to be leading to the page reaching a max 30 second timeout when generating the result.

My code is attached below, it is quite messy at the moment because i've just be working on it, but I was wondering if anyone has any solutions of how I can speed this up or change to prevent a timeout:

Hey,

I'm using a script which allows you to click on a calendar to select the date to submit to the database.

The date is submitted like this: 2014-02-08

Is there a really simple way to prevent rows showing if the date is in the past?

Something like this:
if($currentdate < 2014-02-08 || $currentdate == 2014-02-08) {

}

Thanks very much,
Jack

I teaching myself php, but I am coming from java and other compiled languages, so the process has been a little bumpy. I am trying to do something like this:

Code: [Select]
class my_class
{

  function one ()
  {
     $two = two ();

     $three = three ();

     $five = $two + $three;

     return $five;
  }

  function two ()
  {
     $two = 2;

    return $two;
  }
 
  function three ()
  {
     $three = 3;

     return $three;
  }
}


Unfortunately, I keep getting an error message saying that my call to two () is an undefined function. I am gathering from this that the scope of one () is not aware of the existence of two (). Is there a way to get around this so I can call two () and three () from one ()?

Hello. I'm new to pHp and I would like to know how to get my $date_posted to read as March 12, 2012, instead of 2012-12-03.
Here is the code:
Code: [Select]
<?php

$sql = " SELECT id, title, date_posted, summary FROM blog_posts ORDER BY date_posted ASC LIMIT 10 ";

$result = mysql_query($sql);

while($row = mysql_fetch_assoc($result)) {
$id = $row['id'];
$title = $row['title'];
$date_posted = $row['date_posted'];
$summary = $row['summary'];

echo "<h3>$title</h3>\n";
echo "<p>$date_posted</p>\n";
echo "<p>$summary</p>\n";
echo "<p><a href=\"post.php?id=$id\" title=\"Read More\">Read More...</a></p>\n";
}

?>
I have tried the date() function but it always updates with the current time & date so I'm a little confused on how I get this to work.

I have tried a large number of "solutions" to  this but everytime I use them I see 0000-00-00 in my date field instead of  the date even though I echoed and can see that the date looks correct.

Here's where I'm at:
I have a drop down for the month (1-12) and date fields (1-31) as well as a text input field for the year.  Using the POST array, I  have combined them into the xxxx-xx-xx format that I am using in my field as a date field in mysql. 

<code>
$date_value =$_POST['year'].'-'.$_POST['month'].'-'.$_POST['day'];
echo $date_value;
</code>

This outputs 2012-5-7 in my test echo but 0000-00-00 in the database.

I have tried unsuccessfully to use in a numberof suggested versions of:
strtotime()
mktime

Any help would be extremely appreciated.
I am aware that I need to validate this data and insure  that it is a valid date. That I'm okay with. I would like some help on getting it into the database.

Alright, I have a Datetime field in my database which I'm trying to store information in. Here is my code to get my Datetime, however it's returning to me the wrong date. It's returning:
1969-12-31 19:00:00

$mysqldate = date( 'Y-m-d H:i:s', $phpdate );
$phpdate = strtotime( $mysqldate );
echo $mysqldate;


Is there something wrong with it?

(continuing from topic title)
So if I set a date of July 7 2011 into my script, hard coded in, I would like the current date to be checked against the hard coded date, and return true if the current date is within a week leading up to the hard coded date.

How could I go about doing this easily?

I've been researching dates in php but I can't seem to work out the best way to achieve what I'm after.

Cheers

Hi,

I have a job listing website which displays the closing date of applications using:

$expired_date

(This displays a date such as 31st December 2019)

I am trying to show a countdown/number of days left until the closing date.

I have put this together, but I can't get it to show the number of days.

                    <?php 
                    $expired_date = get_post_meta( $post->ID, '_job_expires', true );
                    $hide_expiration = get_post_meta( $post->ID, '_hide_expiration', true );
                    if(empty($hide_expiration )) {
                        if(!empty($expired_date)) { ?>
                                <span><?php echo date_i18n( get_option( 'date_format' ), strtotime( get_post_meta( $post->ID, '_job_expires', true ) ) ) ?></span>
                    
                    <?php
                                        $datetime1 = new DateTime($expired_date);
                                        $datetime2 = date('d');
                                        $interval = $datetime1->diff($datetime2);
                                        echo $interval->d;

                     ?>
                        <?php }
                    } 
                    ?>

Can anyone help me with what I have wrong?

Many thanks

Hi there,

I have a string '12/04/1990', that's in the format dd/mm/yyyy.

I'm attempting to convert that string to a Date, and then insert that date into a MySQL DATE field.

The problem is, every time I try to do so, I keep getting values like this in the database: 1970-01-01.


Any ideas?


Much appreciated.

Hi guys, I'm putting together a small event system where I want the user to add his own date and time into a textfield (I'll probably make this a series of drop-downs/a date picker later).
This is then stored as a timestamp - "0000-00-00 00:00:00" which displays fine until I try to echo it out as a UK date in this format - jS F Y, which just gives today's date but not the inputted date.



Here's the code I have right now:

Code: [Select]
$result = mysql_query("SELECT * FROM stuff.events ORDER BY eventdate ASC");

echo "<br />";
echo mysql_result($result, $i, 'eventvenue');
echo ", ";

$dt = new DateTime($eventdate);

echo $dt->format("jS F Y");


In my mysql table eventdate is set up as follows:
 
field - eventdate
type - timestamp
length/values - blank
default - current_timestamp
collation - blank
attributes - on update CURRENT_TIMESTAMP
null - blank
auto_increment - blank


Any help as to why this could be happening would be much appreciated, thanks.

I'm getting this Time Zone error.
Perhaps it's a compatibility issue with PHP 5.3. Looked all over for an answer without finding one.
Here is the error message


Warning: date() [function.date]: It is not safe to rely on the system's timezone settings.
You are *required* to use the date.timezone setting or the date_default_timezone_set() function.
In case you used any of those methods and you are still getting this warning,
you most likely misspelled the timezone identifier. We selected 'America/New_York' for 'EST/-5.0/no DST'
instead in /blocked.php on line 41
12/02/12

Here is the code. Line 41 is near the bottom, the one with the d,m,y.  Perhaps the echo date (d/m/y") needs to be changed. Appreciate any help!
