Convert boolean to integer value php

Question

Is there any builtin function for PHP that will take a boolean value and return its integer equivalent? 0 for FALSE, 1 for TRUE? Of course you can easily create a function to do

Answer 1

If you are getting your value in from JSON I.E. Via an AJAX POST, the value will come in as a string (As you have found). A way around this is to compare the true/false string and then cast the bool to an int

$requestBool = $_REQUEST['bool_value']; //This is 'true' or 'false'

$myInt = (int)($requestBool === 'true');
echo $myInt;

//returns: 0 or 1

Answer 2

Normally, simply $myInt = (int)$myBoolean should work, can you show us your code otherwise ?

Answer 3

Just add a "+" before your variable like this :

$myBool = true; 

var_dump(+$myBool);

ouputs: int(1);

Answer 4

You can do multiple castings in a single go:

$isTest = 'true';

(int)(bool)$isTest

echo $isTest; // this outputs 1

Answer 5

Use type casting (bool):

var_dump((bool) 1);         // bool(true)
var_dump((bool) 0);         // bool(false)

Answer 6

// cast to Integer
echo (int)true;         // 1
echo (int)false;        // 0

// get the integer value from argument
echo intval(true);      // 1
echo intval(false);     // 0

// simply echoing true returns 1
echo true;              // 1

// you can even add those values
echo true + true;       // 2
