PHP - Please Clear My Doubt

whats the diff between echo,print,print_r



what's the difference between include(),require,require_once

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"; 
?>

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. With the implementation of our new client portal, we require a new client sign-up api...The following was provided...

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,

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']?>">
