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";
}
?>
