Boolean Values-PHP-

say with me....1,2,3:BOOOOOLEANN!!hahaha

Oke ,it is known as True or False values. True = 1, and False =0. Let we just jump to example !

<?php

$true_value = true;
$false_value = false;

print ("true_value = " . $true_value);
 
print (" false_value = " . $false_value);

?>

OK ,for this script it will show to u the value of true and false,for false,it will print blank NOT the number zero.Another example for proving that true=1 and false=0:

<?php

$true_value = true;
$false_value = false;

if ($true_value == 1) 
{
print("that's true");
}

else
{
print (" false_value = " . $false_value);

 }

?>

Plus,u also can do like this:

<?php

$true_value = true;
$false_value = false;

if ($true_value) 
{
print("that's true");
}

else
{

print (" false_value = " . $false_value);

 }

?>

Besides,NOT also can use with boolean value,like this:

$true_value = true;

if (!$true_value) {
print("that's true");
}
 
else {
print("that's not true");
}


N/NOTE:try it,test it!!god luck!
