PHP - A Doubt Regarding The Use Of Microtime()
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"; ?> Similar Tutorialshi this code will output an unique id like: 0.85760300 1319393114 Code: [Select] $uniqueId= microtime(); echo $uniqueId; my question is: how can i convert this value to something like: Code: [Select] 23/10/2001 19:06 ? thanks 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 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 Nunja whats the diff between echo,print,print_r what's the difference between include(),require,require_once Friends, suppose iam copying 1 to 100 files using a loop in php & when the copy process reach at 50th file my browser went offline. My doubt is will it copy all 100 files ?? OR it will terminate at 50th file ? if i want to get all files copied if the browser went offline then what i want to do ?? Please clear Hi All, being a noob when it comes to any sort of coding I am facing a strong learning curve but I'm getting there.

I have been reading about cURL implementation instead can someone provide some assistance if this is possible and assist. A lot of thank in advance, Andrew Chapman Hi all, Can anyone offer assistance with the following: I am trying to obtain a score from a users radio button selection on a simple quiz. i am not able to obtain the results.... I'm not sure if this is exactly a coding help question, excuse me if its not. I want to know what is the best & secure way to submit a form to itself. I've tried to google the answer, but did not get a proper answer with explanation or may be I didnt use proper keywords to search it. Out of these which one do i use? Code: [Select] // Leave the action field empty. <form method="POST" action=""> //$PHP_SELF, also if i use echo $PHP_SELF my form does not work like it should. <form method="POST" action="<?$PHP_SELF?>"> //$_SERVER['PHP_SELF'], same problem as $PHP_SELF, it doesnt work if i use echo. <form method="POST" action="<?$_SERVER['PHP_SELF']?>"> Hello guys, i need to create a code for making connections with SSL servers (particularly SMTPS and POP3S) and i know about the existence of OpenSSL extension. However, i'm in doubt about a basic issue: 1. Is this extension useful for creating SSL clients or SSL servers? I'm not a SSL expert, so maybe i'm misunderstanding something; i hope you can help me. Kind regards. I have a php code that call a process (a java program). The process runs in background for a so long time - from 1 minute to 2 hours. I make the process call using exec:
<?php
function execInBackground($cmd) {
if (substr(php_uname(), 0, 7) == "Windows"){
pclose(popen("start /B ". $cmd, "r"));
}
else {
exec($cmd . " &> /dev/null &");
}
}
$command = "java ... ReadEmailsCmdLine 2>&1";
execInBackground($command);
echo "FINALIZADO";
Though the command runs in background it looks that the PHP code wait for the command completion to send a answer to client browser because I just see "FINALIZADO" after the java program finished its execution.Does someone know how I can solve this problem? Or at least does have a hint/pointer for that? Since now I thanks any comment/suggestion |
