The day I wanted to test against associative array ...

badaboom.php

<?php

// php -r "var_dump(intval('foo'), intval('foo') == 'foo', 0 == 'foo', (bool) 'foo', 0 == true);"


var_dump(
    intval('foo'),           // 0

    0 == 'foo',              // true
    'foo' == 0,              // true
    
    true == 'foo',           // true
    'foo' == true,           // true
    
    // so when 0 == foo and foo == true then ...
    0 == true                // false
);

echo "meh!";

:D Sehr cool
