Access elements in an object array using an index - PHP

[Graze]

eg.

class Person
{

public $Height;
public $Age;

}


$firstPerson = new Person();
$firstPerson->Height = 136;
$firstPerson->Age = 26;

$secondPerson = new Person();
$secondPerson->Height = 124;
$secondPerson->Age = 18;


Persons = array($firstPerson, $secondPerson);

I have an array of objects that I would like to access using an index syntax instead of having to use the foreach loop in php.


I cant seem to use a normal index like Person[0]->Height to access the Height property of the person at position 0 in the array. In C# it would have been so simple as Person[0].Height

Am I doing something wrong or is there anyway I could do something similar?

Perhaps you meant $Persons?

Also, just from a style perspective, I find your capitalization to be very inconsistent.

LOL, yes, I meant $Persons. This is not what my code looks like but an example of what I want to do that I quickly typed up for the thread.

I use PascalCase for non local variables and methods names and camelCase for local one.

Well, I plugged this into my local Drupal install:

<?php
class Person
{

public $Height;
public $Age;

}


$firstPerson = new Person();
$firstPerson->Height = 136;
$firstPerson->Age = 26;

$secondPerson = new Person();
$secondPerson->Height = 124;
$secondPerson->Age = 18;


$persons = array($firstPerson, $secondPerson);
print_r($persons);
print "The first person's height is ".$persons[0]->Height;
?>

And I got this:

Array ( [0] => Person Object ( [Height] => 136 [Age] => 26 ) [1] => Person Object ( [Height] => 124 [Age] => 18 ) ) The first person's height is 136

Looks right to me. 🙂

And I got this:

Thanks buddy. Knowing it was possible I looked over my code and used the print_r and read thought my messy results.

Turns out I misspelt a property while assigning while assigning a value to it using a loop.
Long story short the first few object properties in the array were messed up and were left blank. When I used the index to access these the would just return nothing so I assumed it wasn't working.

The joys of a dynamic language is that I don't see these things before hand.
