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;
?>

<?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;
?>

<?php
   $mtime = microtime();
   $mtime = explode(" ",$mtime);
   $mtime = $mtime[0];
   $endtime = $mtime;
   $totaltime = ($endtime - $starttime);
   echo "This page was created in ".$totaltime." seconds";
?>

Can please confirm my suspicions of simplexml_load_file() are not permitted. 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,

Openssl Extension Doubt

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.

Doubt Regarding Form Submission

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']?>">

Doubt With Time Consuming Function

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
