time to render page

rul

i have a page and this is its source code

<table width="100%">
  <tr>
    <td>[code=php]<? include("prueba.php"); ?>

</td>
</tr>
<tr>
<td>

<? include("footer.php"); ?>

</td>
</tr>
</table>
[/code]

prueba.php

[code=php]
<?
//im not gonna put the code but it simply makes a search in a big database an return some results
?>

[/code]

and

footer.php

[code=php]
<?
function getmicrotime(){
    list($usec, $sec) = explode(" ",microtime());
    return ((float)$usec + (float)$sec);
    }

$initime=getmicrotime();

echo "PHP version: ".phpversion();
echo "<br>";
echo "MySQL version: ".mysql_get_client_info();
echo "<br>";
echo "Web server: ".php_sapi_name();
echo "<br>";
echo "Operative system: ".php_uname();
echo "<br><br>";

$totaltime=getmicrotime()-$initime;
echo "The page took $totaltime sec. to render";
?>

[/code]

here is the problem,
if i paste footer.php's code into prueba.php's code it gives me the right time but if i do like this way, including the files it gives something like: "The page took 0.02254654 secs to render" this is right but if i refresh it gives me "The page took 6.40153884888E-005 secs to render";

what's wrong?
thanks for helping

wish I could help you as I have code almost identical to that in my footer and it is included also and it gives me the right times.

You might want to read up on how php handles things.

To see if it process in order or if certain tags take priority

6.40153884888E-005, in mathematical terms, is equal to 0.0000640153884888. The E you see in there means "times ten to the ... power." (E stands for exponential, usually in terms of 10 for scientific notation.)

How will this help you? Well, immediately, it doesn't. However, you may know that a float is treated as a non-truncated variable. This tells PHP that it needs to store more of the data than you probably need for this. If you remove the float, it will treat is as a plain number (not an integer, not a float). This plain number will be truncated at a smaller length than the float, so it will not need to be raised to a power to keep more data.

Hope this helps.

but, how can i truncate the scientific notation value to a normal float value??

Try defloating it.

Ever get that sinking feeling? LOL

Sorry, couldn't resist... 😃

how can i defloat¿

Since the fractional part is in (ostensibly) millionths of a second, it can be made into an integer by multiplying by a million. Do all the calculations in microseconds, and then convert back.

$t1 = microtime();
$t1 = explode(' ',$t1);
$t1[0] = $t1[0]*1000000;

//.....[i]code[/i]......//

$t2 = microtime();
$t2 = explode(' ',$t2);
$t2[0] = $t2[0]*1000000;

$tdelta[0] = $t2[0]-$t1[0];
$tdelta[1] = $t2[1]-$t1[1];
$tdelta = $tdelta[0]+1000000*$tdelta[1];

echo $tdelta/1000000; //Elapsed seconds
