Question

I’m getting some benchmark data about page execution time. Its provided by the framework as a string. I want to convert it into a float, multiply it by 1000, and store it in the DB as an int. It seems to be acting really strange and I was hoping someone can help me figure out why. Here is the code:

    $elapsed = $this->benchmark->elapsed_time();
    var_dump("before:");
    var_dump($elapsed);

    $elapsed = floatval($elapsed);

    var_dump("after:");
    var_dump($elapsed);

Here is the result:

EDIT:
I figured this out thanks to someone pointing out that the string length was wrong. Apparently the method is returning the string ‘{elapsed_time}’, the framework is buffering the output, and then replacing that string with the final eval time. Thanks for the help.

<?php

    $time = '0.5643';
    var_dump( $time );        
    //output  :: string(6) "0.5643"
    var_dump( $time * 1000 ); 
    //output  :: float(564.3)
?>

Everything as expected .. but then you do something really stupid like this:

<?php

    $badtime = "\0\0\0\0\0\0\0\0" . $time;
    var_dump( $badtime );        
    //output  :: string(14) "0.5643"

    var_dump($badtime * 1000); 
    //output  :: int(0)

    $goodtime = str_replace("\0", "", $badtime);
    var_dump($goodtime * 1000);
    //output  :: float(564.3)

?>
