First, please wrap PHP code in the appropriate bbCode tags.
Next, here is what it should look like, with comments to answer your question.
Code: Select all
<?php
// Give $freqa a value
$freqa= 24.9;
if ( $freqa != 24.9 )
{
if ( $freqa != 36.4 )
{
// If we are here then $freqa either does not equal 24.9 OR it does not equal 36.4)
echo ("<h1>Not running at 24.9 or 36.4 RUNNING AT $freqa</h1>");
}
else
{
// If we are here then $freqa does not equal 24.9 but it DOES equal 36.4)
echo ("<h1>Running at 36.4</h1>");
}
}
else
{
// We are 24.9
echo ("<h1>Is running normal</h1>");
}
?>

Sorry about that, there is no way in php to OR both statements into one line?

Untested...
Code: Select all
$freqa= '24.9';
switch ($freqa) {
case '24.9':
case '36.4':
echo '<h1>Is Running Normal</h1>';
break;
default:
echo ("<h1>Not running at 24.9 or 36.4 RUNNING AT $freqa</h1>");
}
In your code..
Code: Select all
if($freqa != 24.9 || $freqa != 36.4)
This will
always return true, as $freqa is not going to be equal to one of the two.

you can also do this:
Code: Select all
$freqa= 24.9;
if(($freqa != 24.9) || ($freqa != 36.4)) //this should work
{
echo "<h1>Not running at 24.9 or 36.4 RUNNING AT $freqa</h1>";
}
else
{
echo "<h1>Is running normal</h1>";
}

You might want to take another look at that.
