Wrong Order of Output

[TerraBuilder]

I wrote a statement to display a number and write a string true or false after testing it to be a double. Although, if I write it in the first echo statement, it goes out of order. This wont happen if I separate into another echo statement on the next line.

 

<?
function check($num){ //function to change
if(is_double($num)){
echo "TRUE";
}else{
echo "FALSE";
}
}
$number=3.1415;
echo "Is ".$number." a double?".check($number); //Output
?>

echo true or false in the function will run before the echo of your main statement will, you should use return, your  should have been, I just shorten the code a bit.

 

<?php
function check($num){ //function to change
return is_double($num) ? "TRUE" : "FALSE";
}
$number=3.1415;
echo "Is ".$number." a double?".check($number); //Output
?>
