Just so we all know why...

<?php

$values = array( '', 0, null, '0' );
foreach( $values as $value )
{
    if( $value === '' )
    {
        echo 'If/ElseIf:   The empty string'."\n";
    }
    else
    if( $value === 0 )
    {
        echo 'If/ElseIf:   The integer 0'."\n";
    }
    else
    if( $value === null )
    {
        echo 'If/ElseIf:   The null value'."\n";
    }
    else
    if( $value === '0' )
    {
        echo 'If/ElseIf:   The string value 0'."\n";
    }

    switch( $value )
    {
        case '':
        {
            echo 'Switch/Case: The empty string'."\n";
            break;
        }

        case 0:
        {
            echo 'Switch/Case: The integer 0'."\n";
            break;
        }

        case null:
        {
            echo 'Switch/Case: The null value'."\n";
            break;
        }

        case '0':
        {
            echo 'Switch/Case: The string value 0'."\n";
            break;
        }
    }

    echo "\n";
}

?>
