Change `$civil =` by `$civil ===` http://php.net/manual/en/language.operators.comparison.php — SilvioQ, Mar 01 '19 at 13:32

The '=' is an assignment operator and will be used to assign values to the variables.

$a = 10;

This means store 10 into variable $a;

$a = 20;  
$b = $a;

The above example means first store 20 into variable $a and then store the variable $a into $b. Since $a is 20 and it is being assigned to $b then automatically $b also becomes 20.

Let's come down to the "==". That's the equality operator. It is used to check whether two values are same.

$a = 30;
$b = 30;
if ($a == $b){
    // do something if both are equal
}

The comparison uses "==", checking if $a has the same value as of $b. It's not as precise as "===" (also compares the variable type), but for most uses, "==" is sufficient.

There are a few other operators also, have a look at the documentation: http://php.net/manual/en/language.operators.comparison.php

this does two things wrong: 1) answer a to-be-closed question - they should be flagged appropriately, not answered and 2) used a link as your answer – treyBake Mar 01 '19 at 13:34
you also missed out that `==` checks just value and ignores type. So 2 == '2' returns true - still .. the linked dupe covers all of this and this unfortunately doesn't add anything – treyBake Mar 01 '19 at 13:39
Calm your horses @treyBake, I was writing up a full doc. – dearsina Mar 01 '19 at 13:41
sorry i forgot that ahaahhaha it should be equal to not just an equal – Alfredo Ramirez Mar 01 '19 at 13:44
btw thanks for answering my question – Alfredo Ramirez Mar 01 '19 at 13:45
everyone has made that mistake at least once in their life! :-D – dearsina Mar 01 '19 at 13:47
