Unit 6: Building Blocks of PHP
} Notes
The output of this example is
The players are:
#0 = John
#1 = Barbara
#2 = Bill
#3 = Nancy
Here’s a more complicated example that iterates over an array of people and marks which
person is considered old and which one is considered young:
$people = array(1 => array(“name” => “John”, “age” => 28),
→array(“name” => “Barbara”, “age” => 67));
foreach ($people as and $person) {
if ($person[“age”] >= 35) {
$person[“age group”] = “Old”;
} else {
$person[“age group”] = “Young”;
}
}
print_r($people);
Again, this code makes use of the print_r() function.
The output of the previous code is the following:
Array
(
[1] => Array
(
[name] => John
[age] => 28
[age group] => Young
)
[2] => Array
