Comparing Floats and Strings

[random1]

Hi All,

 

How do you compare floats in PHP?

 

I am comparing browser versions and need to know how compare the following:

 

$browserversion = "2.0.0.14"; // Firefox version

$supportedversion = "2.0.0.00" // Minimum supported version of Firefox

 

if($browserversion >= "2.0.0.00")

{

echo("Browser is supported");

}

else

{

echo("Browser is not supported");

}

 

I also need comparisons for Safari and Opera:

 

e.g. if ($operaversion >= 9.0){echo("Opera version is supported...");}

<?php
$browserversion = "2.0.0.14"; // Firefox version
$supportedversion = "2.0.0.00"; // Minimum supported version of Firefox

if($browserversion >= $supportedversion)
{
    echo "Browser is supported";
}
else
{
    echo "Browser is not supported";
}
?>
gives--> Browser is supported

 

So your problem is what exactly?

The problem is that this returns "Suported browser" regardless off how high or low the browser version is.

Not on my server

<?php
$browserversion = "2.0.0.14"; // Firefox version
$supportedversion = "2.0.0.15"; // Minimum supported version of Firefox

if($browserversion >= $supportedversion)
{
    echo "Browser is supported";
}
else
{
    echo "Browser is not supported";
}
?>

--> Browser is not supported
