Description
The following code shows how to reference arrays in string.
Example

$monthInfo = array(
1=>array("January", 31),
array("February", 28),
array("March", 31),
array("April", 31),
array("May", 31),
array("June", 31),
array("July", 31),
array("August", 31),
array("September", 30),
array("October", 31),
array("November", 30),
array("December", 31));
$userInfo = array(
"Name"=>"Jack",
"Location"=>"Main Street, California",
"Occupation"=>"Programmer");
//Curly braces alert the parser to
//consider the entire array expression,
//including the second dimension.
print("{$monthInfo[1][0]} has {$monthInfo[1][1]} days<br>\n");
//To avoid the confusion by keeping
//the array values outside of the strings.
print($monthInfo[1][0] . " has " . $monthInfo[1][1] . " days <br>\n");
?>
The code above generates the following result.
