If I wanted to create an array in PHP with the following format, what would be the best way to approach it? Basically I want to declare the array beforehand, and then be able to add the values to person_id, name and age.
'person_id' => array('name'=>'jonah', 'age'=> 35)
To the first answer @Joe, first of all, your class doesn't support encapsulation since your attributes are public. Also, for someone who doesn't know how to create an array, this concept may be a bit complicated.
For the answer, changing a bit the class provided by @Joe, PHP provide a simple way of using arrays:
If you need many rows for this array, each row has a number, if not, remove the [0] for only one entry.
$persons = array();
$persons[0]['person_id'] = 1;
$persons[0]['name'] = 'John';
$persons[0]['age'] = '27';
for loop (for multiple records), would I simply remove the 0 from $persons[0]?
Depending on how you want to use it, you could make a simple object:
class Person
{
public $person_id;
public $name;
public $age;
}
$person = new Person; // make the object beforehand
$person->person_id = 123; // their id
$person->name = 'Joe'; // my name
$person->age = 21; // yeah, right
This is virtually identical to an array (in terms of how it's used) except for:
new array() you use new Person (no brackets)['item'] you use ->item
You can start with an empty array:
$arr = Array();
Then add stuff to that array:
$arr['person_id'] = Array();
$arr['person_id']['name'] = "jonah";
$arr['person_id']['age'] = 35;
