Php conditioning a numeric variable

Question

I have this variable in php $get_user_tipo and it gets their own value from a mysqli field (int) and its a numeric value, i'm usign a number to represent a role, por examble 1 for admins, and 2 for employees.

I want to do a conditional statement for the variable and compare it with a value, for example, (a bad, bad example)

if($get_user_tipo=1) {
      do something
} else { 
      Do nothing , just jump to the next check
}
if($get_user_tipo=2) {
      do something
} else { 
      Do nothing , just jump to the next check
}

i'm pretty new in PHP

`if( $get_user_tipo == 1 ) { ... } elseif( $get_user_tipo == 2 ) { ... } else { ... }` Take a look at [basic php tutorial](http://www.w3schools.com/php/) — fusion3k, Feb 25 '16 at 00:48

You need to make sure you use double equals to compare values.

if($get_user_tipo == 1) {
      //do something
} else { 
      //Do nothing , just jump to the next check
}
if($get_user_tipo == 2) {
      //do something
} else { 
      //Do nothing , just jump to the next check
}

Use double = to compare the value as the other answer says

<?php

if ($get_user_tipo == 1) {
    //do something
} elseif ($get_user_tipo == 2) {
    //do something
}

?>

Can i do multiple statements with elseif? – Mr. Jonas The Consultor Feb 25 '16 at 00:56
For this example, as the value you are comparing will be the same I am gonna say yes, but if you are gonna compare different variables I suggest to make other if – Neobugu Feb 25 '16 at 00:59

@Mr.JonasTheConsultor, yes, but you may want to use a [switch](http://php.net/manual/en/control-structures.switch.php) at a certain point. – Devon Bessemer Feb 25 '16 at 00:59

To clarify the other answer, a single = is treated as an assignment operator. This means that you are actually setting $get_user_tipo to 1 in the if statement.

What you want is a comparison operator:

== is a loose equals comparison, meaning '1' (string) is equal to 1 (integer) (type-juggling).
=== is a strict comparison, meaning '1' (string) will not be equal to 1 (integer)

The comparison operators manual: http://php.net/manual/en/language.operators.comparison.php
