PHP - Php Output Buffer Benchmark (microtime Inaccurate When Used With Usleep?)

I am trying to run tests on my pages and see how much time each one of em take to execute.
For this purpose, i'm using this code which i got online:
Code: [Select]
<?php 
   $mtime = microtime(); 
   $mtime = explode(" ",$mtime); 
   $mtime = $mtime[1] + $mtime[0]; 
   $starttime = $mtime; 
?>
<!-- Rest of the php and validation and form elements -->
<?php 
   $mtime = microtime(); 
   $mtime = explode(" ",$mtime); 
   $mtime = $mtime[1] + $mtime[0]; 
   $endtime = $mtime; 
   $totaltime = ($endtime - $starttime); 
   echo "This page was created in ".$totaltime." seconds"; 
?>

microtime() returns microseconds & secs since Unix epoch. So after exploding, why do we add them both?
Cant we just use the microseconds part?

I've tried this code & the one above & both return same time(almost).

Code: [Select]
<?php 
   $mtime = microtime(); 
   $mtime = explode(" ",$mtime); 
   $mtime = $mtime[0]; 
   $starttime = $mtime; 
?>
<!-- Rest of the php and validation and form elements -->
<?php 
   $mtime = microtime(); 
   $mtime = explode(" ",$mtime); 
   $mtime = $mtime[0]; 
   $endtime = $mtime; 
   $totaltime = ($endtime - $starttime); 
   echo "This page was created in ".$totaltime." seconds"; 
?>

I'm using microtime to capture $start_time and $finish_time bothing using microtime() function. I then pass both $start_time and $finish_time into date() function to parse a date. The difference between $start_time and $finish_time is also calculated. The problem being the date() function is producing incorrect values.

list($total_count, $success_count, $errors_data, $start_time, $finish_time) = $summary_data;
$duration_time = $finish_time - $start_time;

echo "<b>Started Processing At:</b> ".date('m/d/Y H:i:m', $start_time)."<br/>";
echo "<b>Completed Processing At:</b> ".date('m/d/Y H:i:m', $finish_time)."<br/>";
echo "<b>Processing Duration:</b> $duration_time seconds<br/><br/>";


The output:

Started Processing At: 11/22/2010 18:45:11
Completed Processing At: 11/22/2010 18:45:11
Processing Duration: 8.0499620437622 seconds

PHP Buffer Flushing is it good or bad?
thank you all.

Hi there,

Can anyone show me how I can grab the value "c87cc576092fe1a0f5ac3d50091694b4" out of this string, it changes.

Also its coming from a socket a $buffer variable, so How can I do this without grabbing everything else aswell, ie all the data after it too

Quote

$buffer = fgets($fp, 4096);      

   /*** recieve data looks like this - <dd><input type="hidden" name="sid" value="c87cc576092fe1a0f5ac3d50091694b4" />

    fclose($fp);
}

fclose($Handle);



If someone could show me how to do this, I think you can do it with the split function, i just dont know how. if someone could show. i'd be SO greatful

I have this inside of a method:
if($output){

$opt = fread($pointer, 10000);

if(!$headers){

$opt = preg_replace("/http.+(\r\n\r\n|\n\n|\r\r)/isU", "", $opt);

}

echo $opt;
}

one of my methods uses fsocketopen to open a file and start processing it. I then have this method which reads out the data to the page. as the file is being processed.

Here is the file that is being processed
Code: [Select]
<?php
function flush_buffers(){
    ob_end_flush();
    flush();
    ob_start();
}
for($i=0;$i<10;$i++){
echo "Test1: $i";
flush_buffers();
usleep(500000);
}
?>
when http outputs the data it also outputs the buffer size as well. I ran it on two files, and here was my output:

Code: [Select]
Test1: cats
b
Test1: cats
b
Test1: cats
b
Test1: cats
b
Test1: cats
b
Test1: cats
b
Test1: cats
b
Test1: cats
b
Test1: cats
b
Test1: cats
0

Test2: 0
8
Test2: 1
8
Test2: 2
8
Test2: 3
8
Test2: 4
8
Test2: 5
8
Test2: 6
8
Test2: 7
8
Test2: 8
8
Test2: 9

Is there any way to remove the buffer size (the "8" and the "b")?
I basically went off of this and converted it to a class: http://phplens.com/phpeverywhere/?q=node/view/254

In one of my servers when ever I call sleep or usleep functions my script sleeps and never wakes up,
Any suggestion on what can cause the issue?
my php -v output:
Code: [Select]
PHP 5.2.17 (cli) (built: Jan 24 2012 20:49:48)
Copyright (c) 1997-2010 The PHP Group

Well I have a script that executes a scan on a system set to run infinitely, and I need it to echo out a message each time it loops through, but I don't want it to echo out the message with the next loop message below it, and the next one below that etc... I've tried using the flush(); function and been messing around with that with no luck. For security reasons I don't want to release any of the processing code, but here is the basic construction of the script:

<?PHP
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
$RepeatIt = -1;
for($g=1; $g!=$RepeatIt+1; $g++)
{
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***

$ScanMessage = ":.:.: SCANNING THE HITLIST FOR MOBSTER: ".$MobName." (SCAN #$g) :.:.:"."<br/><br/>";
echo $ScanMessage;

***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
}
?>

At the moment it's returning:

:.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #1) :.:.:

:.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #2) :.:.:

:.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #3) :.:.:

:.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #4) :.:.:

So what I want it to do is just delete the scanning message and replace it with the next scan message so while running this script you would see just the number increment on the same line.

Any suggestions?

Thanks.

Hi all,

Is there a simple way to log the command output of a linux console?

This command locks up my screen. It is a screen on an Aastra IP phone.

$command = 'logsave /var/www/html/aastra/test.log ls';

shell_exec($command);


Thanks!

Hey folks,

I have made a cart for buying drinks. I also made an sql database. But when I click on the email button, I receive an email but only with the id of the products. I would like to have an output with the id of the product, but also the name of the product ( the name of the column in sql is also 'name')

this is my code and you can check it out on  http://fhcs.be/cart-demo3/

thanks in advance

Hi. I found a code online but unfortunately, the data is retrieved via variables. How can i convert this code to retrieve the data from database instead. Thank you in ADVANCE!

Code: [Select]
var members = [
    ['Steven B. Ayres', '1911-1913', 'New York', 'Independent Democrat', '1861-1929'],
    ['William Augustus Ayres', '1915-1921 1923-1934', 'Kansas', 'Democratic', '1867-1952'],
    ['William Hanes Ayres', '1951-1971', 'Ohio', 'Republican', '1916-2000']
];

I'm not getting any errors but I"m not getting the output I'm expecting. When it gets the characterIDList values if there is a value for that field it needs to take that value then explode it and get the ID and characterName of each of the values so say the value inside of characterIDList was 2,3 then for each of those values it would find the characterName and ID of the value and be able to put each of them as a LI inside the UL.  I was hoping I could have the charactersQuery separate because I use it for the dropdown.

Code: [Select]
$newsQuery = "
    SELECT
        news.categoryID,
        news.newsTitle,
        news.newsPicture,
        news.content,
        news.characterIDList
    FROM
        news
        LEFT JOIN categories
            ON news.categoryID = categories.ID
    WHERE
        news.ID = '" . $newsID . "'";
$newsResult = mysqli_query ( $dbc, $newsQuery ); // Run The Query
echo $newsQuery;
$row = mysqli_fetch_array ( $newsResult, MYSQL_ASSOC );
$characterIDList = $row[ 'chracterIDList' ];

$characterIDList = explode(',',  $characterIDList);

foreach($characterIDList as $value){
    $charactersQuery = "
        SELECT
            ID,
            characterName
        FROM
            characters
        ORDER BY
            characters.characterName";
    $charactersResult = mysqli_query ( $dbc, $charactersQuery ); // Run The Query
}
