Question

Simple question really. I have come across an issue with work where it would be ideal to store >= <= and == into a variable to spit out into certain if statements wherever the case may be.

$numb1 = 5
$numb2 = 10
$option = >=

if($numb1 $option $numb2)

Answer 1

You can’t put a var for testing this in a control instruction.
This will return some : syntax error, unexpected T_VARIABLE

You could use some eval() to do it, but it’s not advisable.

Perhap’s you could make something different with the following :

$option=$_GET['option']; // or POST or something else...
$numb1 = 5;
$numb2 = 10;

switch($option) {
 case ">=":
    if($numb1 >= $numb2){//someting}
    break;
 case "<=":
    if($numb1 <= $numb2){//someting}
    break;
 case "==":
    if($numb1 == $numb2){//someting}
    break;
 default://something else if there is no $option
    break;
}

Or with a function like the following

function testVar($numb1,$numb2,$option)
{
   // Same switch
}
