== and === in php

One reason for I hate PHP

<?php 



if('0001' == '1'){
        echo 'when == test, 0001 and 1 are equal';
}


if('0001' === '1'){
        echo 'when === test, 0001 and 1 are equal';
} 

?> 

Output:
when == test, 0001 and 1 are equal

<?php 

if(1 == true){
        echo 'when == test, 1 and true are equal';
}


if(1 === true){
        echo 'when === test, 1 and true are equal';

}

?>  

Output:
when == test, 1 and true are equal

 Note: any number equals to true, 0 equals to false.

<?php 

if('any string' == true){

        echo 'when == test, any string and true are equal';
}

if('any string' === true){
        echo 'when === test, any string and true are equal';
}


?>   

Output:
when == test, any string and true are equal
