So when I try the following:
$a = '1.00';
$b = '1.01';
if($a < $b){
print 'ok';
}
This works fine. But when I retrieve these variables from an xml file. the strings are EXACTLY the same, but for some reason, the if function doesn't work right. So I assume I have to convert the strings to a number. But when I do so, the decimals get removed.
Is my assumption correct? If so, how do i solve it?
If not, what's the problem?
Thank you!

The number_format() function is used to convert string into a number. It returns the formatted number on success otherwise it gives E_WARNING on failure. echo number_format( $num , 2);
PHP | floatval() Function The floatval() function is an inbuilt function in PHP which returns the float value of a variable. Syntax: float floatval ( $var ) Parameters: This function accepts one parameter which is mandatory and described below: $var: The variable whose corresponding float value will be returned.
The is_numeric() function checks whether a variable is a number or a numeric string. This function returns true (1) if the variable is a number or a numeric string, otherwise it returns false/nothing.
$a = (float) $a;
$b = (float) $b;
